Set the property EvaluateAsExpression to True and then click the Ellipsis button against the Expression property. Select the variable SQLInnerQuery and press F4 to view the properties. SELECT SProcName, SchemaName, Dimension, ETLSchema, ETLTable, IsExecute FROM dbo.SProcValues Paste the following query in the value of the variable SQLGetParameters Other variables relate to each column available in the table so we can loop through each row and hold it in a variable. Variable SQLInnerQuery will hold the query that will be used later in the inner Execute SQL Task. Variable SProcValues will hold the parameter set that we stored in the above-mentioned table. On the SSIS package, assuming that you have the data source and connection manager already established. (SProcName, SchemaName, Dimension, ETLSchema, ETLTable, IsExecute) VALUES Let's insert some sample data using the following script. Based on your stored procedure definition, the table schema would look like this. Let's say the table name is dbo.SProcValues. The example uses SSIS 2008 R2 with SQL Server 2012 backend.Ĭreate a table to store your parameter values. When you create a stored procedure that includes DBCLOB parameters, you need to specify PARAMETER CCSID UNICODE, and if the stored procedure includes DBCLOBs in the body, you need to specify APPLICATION ENCODING SCHEMA UNICODE.Here is one way of doing this. The following example shows a user-defined type stored procedure that includes a double-byte DBCLOB variable. Tip: Db2 translates all Db2 character data between the internal Db2 table Code Character Set Identifier (CCSID) and the external application CCSID. VARGRAPHIC: A varying-length data type used to store a variable-length graphic string.ĬHAR or CLOB defined with “FOR MIXED DATA”: Data types that are used to store character data or mixed data (that is, a combination of single-byte character set (SBCS) characters and multi-byte character set (MBCS) characters).”ĭBCLOB: A double-byte character large object. GRAPHIC: A fixed-length data type that’s used to store a graphic string. This section describes how to code DBCS data in a Db2 for z/OS native stored procedure.ĭb2 for z/OS provides DBCS support for the following data types: If you write SQL applications that support double-byte character languages, you need to know a bit about how Db2 for z/OS supports DBCS data and how character translation is handled. Languages such as Chinese and Japanese contain double-byte characters, which are characters that are too large to represent with a single byte. Working with double-byte character set (DBCS) data Now let’s look at some more complex examples. Now this stored procedure is ready to be deployed. To learn how, see Deploying, running, and debugging stored procedures. The snippet includes some of the more commonly used parameters and an example SELECT statement. The SELECT statement is the part of the stored procedure that gets executed when the stored procedure is called. To see all of the options that you can define in a stored procedure, open the link that is included at the top of the snippet. Select that snippet to populate your file with the basic CREATE PROCEDURE structure (in the following example, the procedure name has already been changed to MYPROCEDURE): You’ll only need to type a few letters before you see CREATE PROCEDURE in the list of available code snippets. spsql file, and start typing CREATE PROCEDURE. Creating a basic stored procedure with code snippets Stored procedures are a powerful tool for increasing the performance and efficiency of distributed applications. Currently, Db2 Developer Extension supports Db2 for z/OS native stored procedures, which are stored procedures that are written entirely in SQL and are created by using the CREATE PROCEDURE or CREATE OR REPLACE PROCEDURE statement, which is available with Db2 12 function level 507 and later. This article covers the basics of using Db2 Developer Extension to create a simple stored procedure and then explains some of the more complex things you might need to do when you create a stored procedure, such as working with DBCS data and user-defined types.
