Determine the characteristic demand of application field.
Form is the essential part of enterprise application software, the exploitation of form for convenience, all kinds of form development systems
In a number of system function is both provided to complete the function that some are general, such as Mathematical treatment, string processing, date lattice
Formula conversion etc..But in actual applications, according to the specific needs of application field, Report Form Design person also need to often use some be
The function that does not have in system function, the date format conversion or number format conversion of such as specific format, and with applied business logic
Related processing function, these functions are accomplished by Report Form Design person's designed, designed and supply its Reusability into SQL.
In the business report system of current main-stream, the method that design SQL is provided mostly.Microsoft
There is provided SQL in crystal report (Crystal Report) system in Visual Studio IDEs
Editing machine designs SQL for user, can be published in the warehouse of reporting system and be set with every other after the completion of design
Meter person is shared to be used.Crystal report SQL design and issue it is all fairly simple, but need to use VISUAL BASIC or
The special programming language of crystal report is write, and has many restrictions to code function, can not be used such as in SQL
Form or Database field, this greatly limits the application of SQL.
Profit universe reporting system, outstanding table reporting system and X5 forms platform are all the parsings that WEB forms are developed with JAVA language
Engine, therefore, they are required to SQL and developed using JAVA language, and it is configured using also will be according to certain regular right
Configuration file enters edlin.For example the flow of one SQL of addition is as follows in profit universe reporting system：
1st, the java classes of SQL are write, are inherited
This class of com.runqian.report4.model.expression.Function.
2nd, under the config catalogues of java class.path, customFunctions.properties files are found, and
The registration of SQL class and function name is carried out wherein.
3rd, at designer end, by customFunctions.properties files copy to designer web WEB-
INF classes under config, by class file copy to designer web WEB-INF under classes, have bag name, phase
The Jian Bao paths answered.
4th, in web terminal, by customFunctions.properties files copy to webapps demo WEB-
INF classes under config, by class file copy to webapps demo WEB-INF under classes, have bag name,
Corresponding Jian Bao paths.
5th, designer is restarted.
6th, SQL is used in designer.
Above-mentioned SQL implementation method advantage is powerful, the volume that JAVA programming languages can be made full use of to provide
Cheng Nengli, form translation function and business logic processing function to user are all easier to realize.
Also a kind of implementation of SQL simply can design and apply SQL【1】.It is square herein
In case, SQL four-tuple Fun={ SQL name, SQL query statement, input parameter number, output parameter
Number } define, the function of function is realized that reports user need to only write this SQL query statement by SQL query statement therein, without
Use other programming languages.After above-mentioned SQL four-tuple is all determined, so that it may be submitted to database, for other forms
Family is shared to be used.It can be embedded in when using as system function in expression formula.The SQL resolving of this scheme
It is as follows：
1st, the identification variables in the expression formula comprising SQL and replacement, all variables all replace with specific value,
Prepared for SQL evaluation.
2nd, the SQL in recognition expression formula.
3rd, by the User-Defined Functions function name stored in database, corresponding SQL query statement and parameter are found
Number information is compared with the variable number obtained, to verify whether variable-definition number is correct.
4th, the parametric variable in SQL query statement is replaced with the actual parameter value of the SQL in expression formula.
5th, SQL query statement of the previous step after variable replacement is performed, return value, i.e. asking as SQL is obtained
Value result replaces its appearance in expression formula.
For profit universe reporting system, the outstanding SQL realization side based on JAVA such as table reporting system and X5 form platforms
Method, its major defect is：
The technical threshold for creating SQL is higher.Various reporting systems require user when designing SQL
Using the programming language specified and by defined said shank, it is necessary to which the SQL of database manipulation also GPRS SQL is compiled
Journey.
The deployment of SQL is complicated, and when SQL is more, workload is big and error-prone.
For with four-tuple Fun={ SQL name, SQL query statement, input parameter number, output parameter number }
The SQL scheme of realization, its main deficiency is function limitation, and SQL is performed and result is obtained and all passed through
What SQL query statement was realized, it is difficult to realize the SQL function of including service logic rule.In addition it is also efficient low
Shortcoming, i.e., perform SQL query statement database server and be required for carrying out syntax check to it every time.
The SQL function of the current each main flow reporting system of comprehensive analysis is realized, it is found that there are the following problems：
The technical threshold for creating SQL is higher.Various reporting systems require user when designing SQL
Using the programming language specified and by defined said shank, it is necessary to which the SQL of database manipulation also GPRS SQL is compiled
Journey.This means common Report Form Design person and user may need one new programming language and its developing instrument of study to set
Count SQL.
The deployment of SQL is complicated.During the SQL deployment of various reporting systems, generally involve
The establishment of multiple files and editor, and to put it under specified file path, some reporting systems also need to restarting and set

" 2014 on August 25, ", with reference to the accompanying drawings 1, following steps will be passed through：ChnDate (today (), ' YYYY MM
The DD days moon ') same day date format is turned into Chinese date format.
Step 1)：SQL and parameter registration.Registration SQL be $ $ chnDate (oldDate,
Format), $ $ chnDate are SQL names, and oldDate is the date to be converted of default form, and format is to expect to turn
The form changed into.
Step 2)：SQL associated storage process is created.A storing process is created in data base management system,
Shape such as chnDate (inParams, outParam), inParams are input parameters, and outParam is output parameter, is character
String type.The processing logic of accompanying drawing 2 is realized in storing process chnDate, the old date to using CSV in inParams
And two parameter values of desired format resolve into the parameter value of two character string types, and date type and structure class are converted into respectively
Type, is then handled it and is set implementing result to output parameter outParam returns.
Step 3)：SQL is used in form.Using example such as
$ STRCAT (" date printeds：", $ $ chnDate ($ TDODAY (), ' YYYY MM months DD day ')), wherein system letter
Number $ STRCAT () are used for two string-concatenations into a character string, and system function $ TDODAY () are used to obtain acquiescence lattice
The current date of formula, if current date is " 08/25/2014 ", above-mentioned example will obtain character string " date printed：201
On August 25th, 4 ".The number of parameters of SQL should be identical with what is registered in step 1.
Step 4)：Recognize the SQL in form., can be very according to SQL prefix and parenthesis matching relation
Readily recognize $ STRCAT (" date printeds：", $ $ chnDate ($ TDODAY (), ' YYYY MM months DD day ')) in make by oneself
Adopted function $ $ chnDate ($ TDODAY (), ' YYYY MM months DD day ').
Step 5)：Identification variables are with replacing in SQL parameter list.$ $ chnDate ($ TDODAY (), ' YYYY
MM months DD day ') in, its parameter list is " $ TDODAY (), ' YYYY MM months DD day ' ", wherein $ TDODAY () are system letter
Number is, it is necessary to evaluation, it is assumed that evaluation obtains result：08/25/2014, $ TDODAY () are replaced in $ $ chnDate ($ TDODAY with it
(), ' YYYY MM months DD day ') in appearance, obtain $ $ chnDate (' 08/25/2014 ', ' YYYY MM months DD day ').Extremely
This, only includes constant in the parameter list of SQL.
Step 6)：Prepare parameter and call SQL associated storage process.Comprise the following steps：1st, SQL
The input parameter value of associated storage process is " ' 08/25/2014 ', ' YYYY MM months DD day ' ".2nd, SQL is set to close
Join the output parameter of storing process；3rd, the name using chnDate as storing process；4th, using storing process name and parameter setting data
Storehouse accesses component, submits storing process to be performed to database server.
Step 7)：Perform step 6) in set storing process and returning result, herein returning result be " in 2014
August 25 ".
Step 8)：Receiving step 7) in storing process returning result and be applied in form expression formula, i.e., by step 7) return
Return result and replace SQL $ $ chnDate ($ TDODAY (), ' YYYY MM months DD day ') (" beaten in expression formula $ STRCAT
Print the date：", $ $ chnDate ($ TDODAY (), ' YYYY MM months DD day ')) in appearance, obtain $ STRCAT (" printing day
Phase：", " 2014 on August 25, "), so far, SQL parsing terminates.
The present invention can also have other alternate embodiments, such as：
In step 1) in, the name of SQL can also be without special prefix, then can when Report Engine is parsed
Obtain the name list of all system functions and SQL from system database with elder generation, then with the function used in form
It is compared.
In step 2) in, the storing process name of SQL association can also be saved in SQL in database
, then can be without derived relation between storing process name and its association SQL name in record, its incidence relation can be from
SQL is found in the register information in database.Then when calling associated storage process for SQL will first from
The storing process name of SQL association is obtained in database.In addition, the processing logic of SQL can also use number
Realized according to the User Defined SQL function in the system of storehouse, with being using storing process difference, the result in storing process
Returned by output parameter, and result is returned by function return value in User Defined SQL function.
The description of the above examples is only intended to facilitate the understand of the core idea of the present invention；Simultaneously for the general of this area
