Accompanying drawing explanation
Fig. 1 is the process flow diagram of the method for data in matched data table of the present invention.
Embodiment
Below, by reference to the accompanying drawings and embodiment, the present invention is described further:
With reference to figure 1, a kind of method of data in matched data table, in order to understand the method for the program better, is described below in conjunction with concrete example.
An existing tables of data, the data in tables of data are as shown in table 1 below:
Table 1:
| Material code | Name of material | Quantity | Project name | Contract number | Color | Thickness | Voltage | Wattage | Highly | Planting patterns |
| YJ0103 | Grouan | 100 | A hotel | 1234 | Ash | 40 | ||||
| SD0201 | Lamp affixed to the ceiling | 50 | B hotel | 1011 | 220 | 100 | ||||
| LH0309 | Camphor tree | 100 | C park | 1414 | 4 | Ground seedling | ||||
| SD0202 | Wall lamp | 80 | A hotel | 1234 | 220 | 80 | ||||
| YJ0103 | Grouan | 80 | D garden | 1331 | Ash | 40 |
In tables of data, field refers to the row in tables of data, and record refers to the row in tables of data, and such as, in table 1, " name of material " these row are called a field, and " SD0201 " this line is called a record.Method of the present invention is as follows:
Steps A: the field in tables of data is divided into a public field region and at least two privately owned field area, wherein, is designated as associate field by the field of in public field region.
According to steps A by " material code ", " name of material ", " quantity " in table 1, " project name " and " contract number " totally 5 fields be divided into public field region, " color " and " thickness " is divided into the first privately owned field area, " voltage " and " wattage " is divided into the second privately owned field area, and " highly " and " planting patterns " is divided into the 3rd privately owned field area." material code " field in public field region is designated as associate field.
Step B: create the association identification identical with privately owned field area quantity for this associate field, an an association identification correspondence association privately owned field area, association identification is added in the data of associate field.Preferably, association identification is added into the head of the data of associate field, and these association identification input interpolation by user.
Create three association identification, be respectively " YJ ", " SD " and " LH ", " YJ " associates with the first privately owned field area, and " SD " associates with the second privately owned field area, " LH " associates with the 3rd privately owned field area, in the data of " material code " field, add association identification.Before not adding association identification, data in " material code " field are respectively " 0103 ", " 0201 ", " 0309 ", " 0202 " and " 0103 ", when the head in " 0103 " adds " YJ ", namely data become " YJ0103 ", and now " YJ0103 " is associated with the first privately owned field area relation.
Step C: receive user to the inquiry request of this tables of data, inquiry request carries querying condition, filters out qualified record according to this querying condition, and the record after screening is designated as screening record; If only have one to screen record, perform a step D, if there are many to screen record, from Article 1 to the last item, screening record performs step D successively.Preferably, querying condition refers to using the data in a certain field as key word of the inquiry.
Such as, querying condition in the inquiry request of user is, data in " name of material " field are the record of " grouan ", record is obtained particular by performing database query statement, after having responded the inquiry request of user, by filtering out the record meeting querying condition, from table 1, the screening meeting querying condition records two.
The data corresponding to this field name in field name in privately owned field area associated by it and this screening record are combined, to form a data splitting by step D: according to the association identification in this screening record; The data corresponded in this screening record in public field region and data splitting are formed a new record, the record that this is new is designated as matched record; Wherein, if field name have n, n be greater than 1 integer, then the data of a field name and its correspondence form the part in data splitting, and whole data splitting is made up of n part.
In step C, that inquires about " grouan " records two, then need to perform twice step D successively from Article 1 to Article 2.Such as, in Article 1 screening record, as known from Table 1, the association identification in this screening record is in " material code " field, and be specially " YJ ", associated by " YJ " is the first privately owned field area, i.e. " color " and " thickness " field.
Corresponding to table 1, that " color " and " ash " is combined according to the content of step D, specifically " color " and " ash " can be combined into " color ash ", or further, a symbol is added between " color " and " ash ", be combined into " color: ash ", the form of its combination is not limited to above-mentioned described form.Description conveniently, is described unifying with " field name: corresponding data " this form.
Because there are " color " and " thickness " two field names, therefore " color: ash " is the part in data splitting, " thickness: 40 " is also the part in data splitting, and " color: ash " and " thickness: 40 " these two parts have been combined into a data splitting.Preferably, can be distinguished with a separator between every two parts, specifically can add between the two sections "; ", namely form " color: ash; Thickness: 40 " this form.
The data corresponded in this screening record in public field region and data splitting are formed a new record, the record that this is new is designated as matched record.Then recording according to Article 1 screening the matched record obtained is, " ' YJ0103 ', ' grouan ', ' 100 ', ' A hotel ', ' 1234 ', ' color: ash; Thickness: 40 ' ".And then for Article 2 screening record execution step D, just can obtain another matched record is, " ' YJ0103 ', ' grouan ', ' 80 ', ' D garden ', ' 1331 ', ' color: ash; Thickness: 40 ' ".
By step D, useful field (field in the privately owned field area of the field in public field region and correspondence) is extracted exactly in screening record, field in other privately owned field area can be regarded as extraneous data or unconcerned data at this screening record, filters it.
Step e: create a form, by the data Replica in matched record in form.Further, in each cell of the first row of form, insert the attribute-name of the data in the row representing this cell place respectively.Wherein, attribute-name is just located therein when creating form.
Particularly, in conjunction with above-mentioned obtained two matched datas, form obtained in this step and data as shown in table 2.
Table 2:
In order to the flow process of the method is described better, below again for an example.
Be still for table 1, after carrying out steps A and step B, in step C, the querying condition of user is, the data in " contract number " field are the record of " 1234 ".Get two matched record through step D, then through step e generate form and data as shown in table 3.
Table 3:
As can be seen from above-mentioned method, technical scheme of the present invention has following beneficial effect: by carrying out Region dividing to the data in tables of data, incidence relation between preset data and data, when user is by after input inquiry condition, data in the record returned are only the data that user is concerned about, fall recording irrelevant Field Sanitization with this, finally return data in table form, make presenting of data very succinct directly perceived, what be conducive to raising user checks efficiency.Such as, if having 10 privately owned field area in a tables of data, if return a complete documentation in this tables of data for the querying condition of user's input, so this record will be very long, and the inside can comprise some fields had nothing to do with this record.Therefore filtering out the data that these fields can make to return is all the data that user is concerned about.
Corresponding to above-mentioned method, also disclose the device of data in a kind of matched data table below, comprise with lower module:
Modules A: for the field in tables of data being divided into a public field region and multiple privately owned field area, the field of in public field region is designated as associate field;
Module B: for creating the association identification identical with privately owned field area quantity for this associate field, an an association identification correspondence association privately owned field area, association identification is added in the data of associate field;
Module C: for receiving the inquiry request of user to this tables of data, inquiry request carries querying condition, filters out qualified record according to this querying condition, is designated as screening record by the record after screening; If only have one to screen record, perform a step D, if there are many to screen record, from Article 1 to the last item, screening record performs step D successively;
Module D: for according to the association identification in this screening record, the data corresponding to this field name in the field name in the privately owned field area associated by it and this screening record are combined, to form a data splitting; The data corresponded in this screening record in public field region and data splitting are formed a new record, the record that this is new is designated as matched record; Wherein, if field name have n, n be greater than 1 integer, then the data of a field name and its correspondence form the part in data splitting, and whole data splitting is made up of n part;
Module E: for creating a form, by the data Replica in matched record in form.
In module B, association identification is added into the head of the data of associate field.
In module C, querying condition refers to using the data in a certain field as key word of the inquiry.
