DB2 DBVISUALIZER CREATE STORED PROCEDURE HOW TO
Cursors can be used, if one by one row needs to be processed. Db2 dbvisualizer create stored procedure how to In the query window, enter the following statements that use the sys.sqlmodules catalog view.Returns values of the parameters passed.Gives status back to the calling module.It is compiled once and used many a times.Supports languages like SQL, COBOL, C, REXX, PLI, ASSE, JAVA.Parameters can be supplied to the above SP if they are declared while creating SP. In mainframes environment, A stored procedure can be invoked from an application program USING A CALL or it can be invoked from the Command Line. RUN OPTIONS "MSGFILE(OUTFILE),RPTSTG(ON),RPTOPTS(ON)" OUTCODE INTEGER OUT, PARMLST VARCHAR(254) OUT) This example creates the same stored procedure as above using a different procedure name. Copy and paste the following example into the query window and click Execute.
This process gives a name, declares IN & OUT parameters, Sets the external Language etc.Įxample: CREATE PROCEDURE STRD001(PROCNM CHAR(18) IN, SCHEMA CHAR(8) IN, In Object Explorer, connect to an instance of Database Engine.
Native Stored procedures are written in SQL language.Įxternal Stored procedures are written along with the host language like COBOL.Ĭreating external stored procedures involves in defining/CREATING the SP to DB2 and coding of SP logic in Language defined. This table contains this SP details in columns like Specific Schema, Specific Name(Procedure name), Routine Type, Routine Body, SQL Data Access, Path & External Name Etc.Ĭan be coded just like any other cobol db2 program with the required SQL statements inside it. Once the Stored procedure is created, a row gets created in SYSROUTINES table. It is a data base Object which performs certain business logic so it is also considered as a program. Good thing about Stored procedures are, when it gets compiled and called for the first time the execution plan gets stored in the database which gets used in further invocations of this SP. Invoking Stored Procedures: In mainframes environment, A stored procedure can be invoked from an application program USING A CALL or it can be invoked from the Command Line. Stored procedures are DB2 objects and must be defined to DB2 using CREATE PROCEDURE Statement. These are ALSO considered as the programs that are compiled and stored in a DB2 server which can be called/INVOKED from any application program.
DB2 DBVISUALIZER CREATE STORED PROCEDURE CODE
You must then modify the template to something that is syntactically correct, but we still recommend that you finish the real code in the Code Editor instead.Ĭlick Execute in the dialog to create the new procedure.DB2 stored procedures mainframe–> Stored procedures are the programs that contains one or more SQL statements to perform a business functionality and can be called by any application with SQL call statements. What you create with the assistant should be seen as a template that you then complete and work with in the editor.įor some databases the sample code is editable because there is no way to write a generic sample that compiles. The real code is often complex and large, so DbVisualizer provides a more powerful editing environment than would fit in a dialog via the Code Editor. For most databases, you can not enter the real code in the action dialog. The dialog uses this information together with a simple sample body to compose a CREATE statement.

Create Database Databases, Session SQL Mode1CatalogExport Database. For some databases you can also enter a direction (typically IN, OUT, or INOUT) and a default value.
