Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a flowchart of a character extraction method of a database statement according to an embodiment of the present invention, where the character extraction method includes:
step S11: when a target character string in a target SQL statement is to be extracted, setting a corresponding regular expression according to the target character string, and performing rule matching on the target SQL statement by using the regular expression;
step S12: if the screening character string meeting the regular expression exists in the target SQL statement, adding a first identifier and a second identifier at the initial position and the end position of the screening character string respectively to obtain a modified SQL statement;
the first identifier and the second identifier are identifiers which are different from any character in the target SQL statement;
step S13: character-by-character matching is carried out on the modified SQL statement;
step S14: and when the first identifier and the second identifier in the modified SQL statement are matched, extracting the character string between the first identifier and the second identifier to obtain a target character string.
In this embodiment, a method for extracting characters from an SQL statement is provided, by which special content characters can be extracted from the SQL statement. Specifically, when a target character string in a target SQL statement is to be extracted, a corresponding regular expression is set according to the target character string, and the regular expression is used to perform rule matching on the target SQL statement. Wherein, the target character string is a special content character, such as: 2021-7-211: 11:11, jasmine, cola, etc.
If the screening character string meeting the regular expression exists in the target SQL statement, the regular expression set according to the target character string is adapted to the target character string, in this case, a first identifier and a second identifier need to be added to the initial position and the end position of the screening character string in the target SQL statement respectively, and the modified SQL statement is obtained. The first identifier and the second identifier added to the start position and the end position of the filter string may be any identifiers that can be distinguished from any character in the target SQL statement.
After the first identifier and the second identifier are added to the initial position and the end position of the screened character of the target SQL statement to obtain a modified SQL statement, character-by-character matching can be carried out on the modified SQL statement; after the first identifier and the second identifier are matched in the SQL statement in a character-by-character matching mode, the target character string can be extracted from the position between the first identifier and the second identifier.
Such as: when the target SQL statement is selected from static time, 2020-9-811:4:11, if the target SQL statement is matched by using the character-by-character matching rule in the prior art, the character string "2020-9-811: 4: 11" cannot be extracted from the target SQL statement. In this case, the regular expression may be set according to the character string "2020-9-811: 4: 11" first. The regular expression corresponding to the character string '2020-9-811: 4: 11' in the target SQL statement is as follows: (\ d {2} | \ d {4}) (? ([0] {1} \ d {1} | [1] {1} [0-2] {1}) (? ([0-2] {1} \ d {1} | [3] {1} [0-1] {1}) (? ([0-1] {1} \ d {1} | [2] {1} [0-3] {1}) (? ([0-5] {1} \ d {1}) (? ([0-5] {1} \ d {1}) before character-by-character matching is performed on the target SQL statement, whether a screening character string meeting the regular expression exists in the target SQL statement needs to be detected. If the filtering character string "2020-9-811: 4: 11" satisfying the regular expression exists in the target SQL statement, identifiers &% # and #% &arerespectively added at positions before and after the filtering character string "2020-9-811: 4: 11", and at this time, the target SQL statement becomes a modified SQL statement select &fromstaff time &% # 2020-9-811:4:11 #% &.
And then, performing character-by-character analysis on the modified SQL statement according to the existing character-by-character matching rule, and when the identifiers of &% # and #% & exist, extracting the character string between the identifiers of &% # and #% & in the modified SQL statement, so as to extract the character string '2020-9-811: 4: 11' from the modified SQL statement.
In addition, in practical applications, the method provided by this embodiment may also be used to analyze the SQL statement select from staff name, since the existing character-by-character matching rule cannot be used to extract "three pages" in the SQL statement. Specifically, when the SQL statement select from stop work where name is three, a regular expression corresponding to "three" needs to be set first, and the SQL statement select from stop work where name is three is matched with "three" by using the regular expression corresponding to "three", if a character string of "three" is matched in the SQL statement, then &% & and &% & m% are added before and after "three", so that the SQL statement select from stop work where name is three.
Then, the existing character-by-character matching rule is used for analyzing the SQL statement select from staff hand where name &% & three &% & when the character strings in the SQL statement are identified as &% & and &% & the & +, the character string in the middle of &% & and &% & can be extracted, so that the special character string of 'three' can be extracted from the SQL statement select from staff hand where name &% & three &% & the special character string can be extracted.
It can be understood that, compared with the prior art, the technical solution provided in this embodiment can convert the target character string in the target SQL statement into a character string recognizable by the character-by-character matching rule, so that the special content characters can be extracted from the target SQL statement by the method.
It can be seen that, in this embodiment, when a target character string in a target SQL statement needs to be extracted, first, a corresponding regular expression is set according to the target character string, and the regular expression is used to perform rule matching on the target SQL statement; if the screening character string meeting the regular expression exists in the target SQL statement, adding a first identifier and a second identifier at the initial position and the end position of the screening character string respectively to obtain a modified SQL statement; the first identifier and the second identifier are identifiers which are different from any character in the target SQL statement; and then, carrying out character-by-character matching on the modified SQL statement, and when a first identifier and a second identifier in the modified SQL statement are matched, extracting a character string between the first identifier and the second identifier to extract a target character string in the target SQL statement. Obviously, the method provided by the embodiment can convert the target character string in the target SQL statement into the character string recognizable by the character-by-character matching rule, so that the target character string which cannot be recognized in the target SQL statement can be extracted, and the purpose of extracting the special content characters from the SQL statement is achieved.
Based on the above embodiments, this embodiment further explains and optimizes the technical solution, and as a preferred implementation, the target character string includes a special character and/or an SQL character string and/or a character.
Specifically, in this embodiment, the target character string of the special content character in the target SQL statement may be a special character, or may be an SQL character string or a text, etc. Such as: the target character string may be zhang san, lie si, 2020-9-8, name, etc., as long as the character string cannot be extracted from the target SQL statement by using the existing character-by-character matching rule.
Therefore, by the technical scheme provided by the embodiment, the application range of the SQL statement character extraction method provided by the application can be further widened.
Based on the foregoing embodiment, this embodiment further describes and optimizes the technical solution, and as a preferred implementation, the character extraction method further includes:
and storing the regular expression.
In this embodiment, after the regular expression corresponding to the target character string is set, the regular expression may also be stored in order to expand the template extraction library of the target SQL statement. Therefore, in the subsequent matching process of the character string in the target SQL statement, the regular expression can be directly used for judging whether the character string which is required to be extracted by the user exists in the target SQL statement.
Based on the above embodiment, this embodiment further describes and optimizes the technical solution, and as a preferred implementation, the first identifier and the second identifier are specifically user-defined identifiers.
In this embodiment, when the first identifier and the second identifier are added to the start position and the end position of the screening character string of the target SQL statement, the first identifier and the second identifier may be set according to the code writing habit of the user. The first identifier and the second identifier defined by the user may be the same or different, as long as the first identifier and the second identifier can be distinguished from the characters in the target SQL statement, and character-by-character matching of the target SQL statement is easy.
Obviously, by the technical scheme provided by the embodiment, the flexibility of the user in setting the first identifier and the second identifier can be relatively improved.
Based on the above embodiments, this embodiment further describes and optimizes the technical solution, and as a preferred implementation, the first identifier and the second identifier are specifically identifiers appearing in pairs.
In practical applications, when the first identifier and the second identifier are added to the starting position and the ending position of the screening character string of the target SQL statement, the first identifier and the second identifier may also be set as identifiers that appear in pairs, such as: ", [ sic ], { }, [ sic ], and the like.
It is conceivable that, when the first identifier and the second identifier are set as identifiers appearing in pairs, in the process of performing character-by-character matching on the modified SQL statement, matching and recognition of the paired identifiers appearing in the modified SQL statement is easier, which not only improves the extraction efficiency of the target character string, but also improves the extraction accuracy of the target character string.
Obviously, by the technical scheme provided by the embodiment, the accuracy in extracting the target character string can be further ensured.
Based on the foregoing embodiment, this embodiment further describes and optimizes the technical solution, and as a preferred implementation, the character extraction method further includes:
and if the screening character string meeting the regular expression does not exist in the target SQL sentence, re-executing the step of setting the corresponding regular expression according to the target character string and performing rule matching on the target SQL sentence by using the regular expression until the screening character string meeting the regular expression exists in the target SQL sentence.
In this embodiment, if there is no filtering character string satisfying the regular expression in the target SQL statement, it indicates that the regular expression set according to the target character string is not adapted to the target character string. In this case, in order to ensure smooth proceeding of subsequent steps and to be able to extract a target character string of a special content character from a target SQL statement, the step of setting a corresponding regular expression according to the target character string and performing rule matching on the target SQL statement by using the regular expression needs to be executed again until a screening character string satisfying the regular expression appears in the target SQL statement.
Obviously, the technical scheme provided by the embodiment can further ensure that the target character string of the special content character can be extracted from the target SQL statement.
