Described in embodiment do not represent all implementations consistent with this disclosure.On the contrary, they be only with it is such as appended
The example of the consistent device and method of some aspects be described in detail in claims, the disclosure.
Before introducing data query method, apparatus, storage medium and the electronic equipment of disclosure offer, first to this public affairs
It opens application scenarios involved in each embodiment to be introduced, includes server and terminal in the application scenarios, terminal can
It is communicated by network with server, database (such as can be Hbase database) is contained in server, can be received
The inquiry request that terminal is sent, and query result is returned into terminal.Wherein, server can be local server, can also be with
Cloud server, terminal for example can be smart phone, tablet computer, smart television, smartwatch, PDA (English:
Personal Digital Assistant, Chinese: personal digital assistant), the mobile terminals such as portable computer, be also possible to platform
The fixed terminals such as formula computer.
Fig. 1 is a kind of flow chart of data query method shown according to an exemplary embodiment, as shown in Figure 1, the party
Method is applied to server, comprising:
Step 101, the inquiry request sent by terminal is parsed, it is corresponding to obtain at least one query information in inquiry request
At least one query pattern.
For example, when user requires to look up the data in database, inquiry can be sent by terminal to server and asked
It asks, may include the data to be inquired of user in inquiry request, is i.e. query information, query information can be one or more.Clothes
Device be engaged in after receiving inquiry request, each of inquiry request query information is parsed, to obtain this at least one
The corresponding one or more query patterns of query information.Wherein, the query information in inquiry request can be according to preset DSL
(English: Domain-specific Languages, Chinese: field language-specific) description, server is to inquiry request with right
The DSL answered parses query information, and to obtain the corresponding query pattern of query information, query pattern, which can be understood as user, to be looked into
The attribute of the data of inquiry, i.e., the data format of a certain data column in database, query pattern can have one or more, each
The data format of a certain data column in query pattern correspondence database.It is required to look up in database with user comprising identification card number
For 211123456789101234 and name be Li Ming data, pass through terminal to server send inquiry request, inquiry request
Including<211123456789101234>AND<Li Ming>, i.e., " 211123456789101234 " are a query information, " Li Ming "
For a query information, server parses two query informations, and obtain two query patterns: 17 or 18 bit digitals are (i.e.
The corresponding query pattern of identification card number), 2-4 Chinese characters (i.e. the corresponding query pattern of name).
Step 102, search whether exist and matched first line unit of at least one query pattern in concordance list.
It is exemplary, search whether to exist in concordance list with matched first line unit of whole query patterns, can in concordance list
It further include these data column pair with the mode comprising certain data column (or referred to as field) in tables of data each in database
One or more line units are answered, while can also be including the corresponding table name of line unit each in these line units, wherein table name can be unique
Mark data table, it is also necessary to which explanation is.First line unit can be zero, one or more.When the first line unit is not present (i.e. zero
It is a) when, indicate do not have to arrange with the data of whole query pattern exact matchings in concordance list, when the first line unit is one or more
When, indicate that there are data exactly match with whole query patterns in concordance list arranges, the corresponding line unit of these data column is the
One line unit.It is arranged with the matched data of whole query patterns, it can be understood as the mode of data and query pattern be one by one in data column
It is corresponding, i.e., according to the corresponding relationship of line unit in concordance list and query pattern, by concordance list with the matched whole rows of query pattern
Key is as the first line unit group.For example, in concordance list there are two data column in data, respectively meet 17 or 18 bit digitals
Mode and 2-4 Chinese characters mode, then can determine the two data column with<211123456789101234>AND<Lee
Bright > the query pattern that is parsed matching, it is the first line unit that the two corresponding data, which arrange corresponding line unit,.It needs to illustrate
It is the data column for including in concordance list, corresponding data column in the query pattern inquired before can be are also possible in advance
Specified certain data column.
Step 103, when in concordance list there are when at least one first line unit, in the database by least one the first row
In the data line that key is identified, search and the matched data line of at least one query information.
Step 104, terminal will be sent to as query result with the matched data line of at least one query information.
For example, when there are one or more line units in concordance list, according to the relationship of line unit in concordance list and table name,
It determines the corresponding table name of each first line unit, determines that each first line unit is corresponding further according to the corresponding table name of each first line unit
Tables of data, then the data line that all the first line unit is identified in tables of data is obtained, later in the number that all the first line unit is identified
It, finally will be with the matched data line of at least one query information according to lookup in row and the matched data line of at least one query information
Terminal is sent to as query result.Wherein, the quantity of the first line unit is greater than or equal to the number of tables of data, i.e. a tables of data
One or more first line units can be corresponded to.For example, inquiry request includes<211123456789101234>AND<Li Ming>, then
The query pattern parsed is 17 or 18 bit digitals and 2-4 Chinese characters namely query pattern is identification card number and name, it is assumed that rope
Draw in table there are two data column to match respectively with 17 or 18 bit digitals and 2-4 Chinese character the two query patterns, accordingly this
Two data column have corresponded to three line units, then these three line units are exactly that the first above-mentioned line unit (can be understood as having found and meet
The mark of the data line of querying condition in inquiry request), it is assumed that these three first line units are respectively as follows: 1001101,1100110,
1100111, then can take out 1001101,1100110,1,100,111 three data lines identified in database, then this three
Inquiry includes the data line of " 211123456789101234 " and " Li Ming " in a data line, is sent to end as query result
End.
For example, storing the population information in certain city in database, it is now desired to searching name in database is " Wang Ming ",
Identification card number be " 610123456789101234 ", gender be " male " data, can be inputted by terminal<Wang Ming>AND<
Inquiry request is sent to server by the inquiry request of 610123456789101234>AND<male>, terminal.Server is receiving
To after the inquiry request, inquiry request is parsed, to three query informations " Wang Ming " for including in inquiry request,
" 610123456789101234 " and " male " seek corresponding regular expression respectively, to obtain three query patterns: 2-4 Chinese characters
(the corresponding inquiry of gender of the bit digital of (the corresponding query pattern of name), 17 or 18 (the corresponding query pattern of identification card number), 0 or 1
Mode).Later, searched whether in concordance list exist with matched first line unit of whole query patterns, i.e., in search index table
With the presence or absence of the data in three data column, meet the mode of the bit digital of 2-4 Chinese characters, 17 or 18,0 or 1 respectively, if deposited
Arranging corresponding line unit in, these three data is the first line unit, such as three data arrange corresponding two the first line units, are respectively as follows:
1111101,1100000, two data lines of 1111101,1100000 marks in database are taken out, finally by the two data
Data line in row including " Wang Ming ", " 610123456789101234 " and " male " is sent to terminal as query result, such as
Include " Wang Ming " in the data line of 1100000 marks, but does not include " 610123456789101234 " and " male ", and 1111101
Include simultaneously in the data line of mark " Wang Ming ", " 610123456789101234 " and " male ", then by the data of 1111101 marks
1111101 data lines identified are taken out in the corresponding tables of data of row, are sent to terminal as final query result.
In conclusion the disclosure receives the inquiry request sent by terminal first, by parsing inquiry request, to be looked into
Asking includes at least one corresponding query pattern of at least one query information in request, then search whether in concordance list to exist with
Matched first line unit of at least one query pattern, when there is one or more first line units in concordance list, all first
Lookup and the matched data line of at least one query information in the data line that line unit is identified will finally be believed at least one inquiry
Matched data line, which is ceased, as query result is sent to terminal.It can be realized the inquiry to distributed data base, improve distribution
The search efficiency of formula database, saves storage resource.
Fig. 2 is the flow chart of another data query method shown according to an exemplary embodiment, as shown in Fig. 2, step
Rapid 103 can be realized by following steps:
Step 1031, when in concordance list there are when at least one first line unit, by the first line unit of at least one in database
The data line identified is as target line.
Step 1032, it is searched and the matched data line of at least one query information in target line.
It is exemplary, when there is one or more line units in concordance list, according to the relationship of line unit in concordance list and table name, really
Determine the corresponding table name of each first line unit, determines the corresponding number of each first line unit further according to the corresponding table name of each first line unit
According to table, then using all the data line that is identified of the first line units is searched in target line and extremely later as target line in tables of data
A few matched data line of query information.
Optionally, step 1031 can be accomplished by the following way:
1) when there are when at least one first line unit, determine corresponding first table name of each first line unit in concordance list.
2) tables of data that each first table name is identified is searched in the database.
3) at least one data line that at least one first line unit is identified is determined in all tables of data.
4) will an at least data line as target line.
For example, when in concordance list there are when at least one first line unit, first according to line unit in concordance list and table name
Corresponding relationship, determine corresponding first table name of each first line unit, wherein the quantity of the first line unit be greater than or equal to the first table
Quantity (the i.e. tables of data of corresponding first table name mark of first line unit, the tables of data of first table name mark of name
May include multiple first line units), then determine the tables of data that the first table name is identified in database, all tables of data are obtained later
The total data row (the first line unit and data line correspond) that middle the first line unit of whole is identified, finally makees total data row
For target line.For example, arranging in concordance list there are two data is parsed with<211123456789101234>AND<Li Ming>respectively
Query pattern matching out, the two corresponding data arrange corresponding three the first line units, be respectively as follows: 1001101,1100110,
1100111, first determine the corresponding table name of three the first line units, table name belonging to 1001101 are as follows: 0x5211,1100110 Hes
Table name belonging to 1100111 is all 0x7100, then the corresponding tables of data of 0x5211 and 0x7100 is searched in the database, and
A 1001101 corresponding data lines are taken out in the tables of data of 0x5211 mark, are taken out in the tables of data of 0x7100 mark
1100110,1100111 corresponding two data lines, using these three data lines as target line.
Fig. 3 is the flow chart of another data query method shown according to an exemplary embodiment, as shown in figure 3, step
Rapid 101 may include:
Step 1011, according at least one query information, the matched regular expression of each query information is obtained.
Step 1012, using the matched regular expression of each query information as a query pattern.
It is exemplary, it may include one or more query informations in inquiry request, query information for example can be text
Format, by the corresponding data of each query information according to regular expression (English: Regular Expression) rule into
Row description, to obtain the matched regular expression of each query information, using the matched regular expression of each query information as
One query pattern, the i.e. corresponding query pattern of a regular expression, multiple regular expressions correspond to multiple queries mode.
Correspondingly, query pattern is matched with data column, then it can be understood as regular expression corresponding to the data in data column and look into
The corresponding regular expression of inquiry mode is identical.It is<Zhang San>AND<male>citing with inquiry request, server can remove inquiry and ask
After the bound symbol (such as: AND, OR etc.) asked, parse two query informations for including in inquiry request: " Zhang San " and
" male " " male " corresponding data are described according to the rule of regular expression, i.e., 0 or 1 (the corresponding query pattern of gender),
" Zhang San " corresponding data are described according to the rule of regular expression, i.e. 2-4 Chinese character (the corresponding inquiry mould of name
Formula), by " name ", " gender " corresponding two regular expressions as two query patterns.
Fig. 4 is the flow chart of another data query method shown according to an exemplary embodiment, as shown in figure 4, should
Method is further comprising the steps of:
Step 105, it when the first line unit is not present in concordance list, searches and the matched target of query pattern in the database
Data arrange, and the matched regular expression of data institute in target data column is identical as query pattern.
It for example, can be by searching in the database and query pattern when the first line unit is not present in concordance list
Matched target data column are to inquire data, wherein the matched regular expression of data institute and inquiry mould in target data column
Formula is identical.
Step 106, when there are when at least one target data column, determine at least one target data column correspondence in database
At least one second line unit and corresponding second table name of each second line unit.
Step 107, the tables of data that each second table name is identified is searched in the database.
Step 108, at least one data line that at least one second line unit is identified is determined in all tables of data.
Step 109, at least one data line at least one second line unit identified at least one query information
Matched data line is sent to terminal as query result.
It is exemplary, when there are target data column matched with query pattern in database, it can determine that target data arranges
Corresponding second line unit and corresponding second table name of each second line unit.Wherein, the second line unit can be one or more, the
The quantity of two table names is less than or equal to the quantity of the second line unit.Corresponding tables of data is determined further according to the second table name, finally by institute
Have in tables of data in the total data row (the second line unit and data line correspond) that all the second line units are identified at least one
A matched data line of query information is sent to terminal as query result.Above-mentioned determines at least one in all tables of data
At least one data line that second line unit is identified, and at least one data line that the second line unit is identified determine with extremely
The method that a few matched data line of query information is sent to terminal, and is directed to the first line unit mark in above-mentioned steps 103 and 104
The processing method at least one data line known is identical, repeats no more.
Step 110, according at least one second line unit, corresponding second table name of each second line unit and query pattern, more
New concordance list.
It is exemplary, it, will after the second line unit and corresponding second table name of each second line unit have been determined in step 106
Corresponding relationship between query pattern and the second line unit, the second table name is stored in concordance list, updates concordance list to inquire energy later
It is enough that query result is directly obtained according to concordance list.Wherein it is possible to by the corresponding relationship of each second line unit and query pattern, look into
The corresponding relationship of inquiry mode and target data column, is stored in concordance list, i.e., it is corresponding with query pattern to contain line unit in concordance list
The corresponding relationship of data arrange in relationship, query pattern and database corresponding relationship, line unit and table name, wherein line unit and data
Row corresponds, and table name and tables of data correspond, and tables of data may include one or more line units.
Fig. 5 is the flow chart of another data query method shown according to an exemplary embodiment, as shown in figure 5, step
Rapid 109 may comprise steps of:
Step 1091, at least one data line at least one second line unit identified is as target line.
Step 1092, end is sent to as query result with the matched data line of at least one query information using in target line
End.
It is exemplary, when there are target data column matched with query pattern in database, it can determine that target data arranges
Corresponding second line unit and corresponding second table name of each second line unit.Wherein, the second line unit can be one or more, the
The quantity of two table names is less than or equal to the quantity of the second line unit.Corresponding tables of data is determined further according to the second table name, finally by institute
There is the total data row (the second line unit and data line correspond) that all the second line unit is identified in tables of data to be used as target line,
Terminal is sent to as query result with the matched data line of at least one query information using in target line again.
It should be noted that being determined in step 102 and the first row being not present when concordance list is empty (when first inquiry)
