Chapter 3: RDBMS Stored Procedure Details Run Stored-Procedure details This section provides: • A complete, detailed reference for all the syntax expressions and options you can use to define the RUN STORED-PROCEDURE and the associated language elements that comprise a stored procedure definition. • Syntax to use the RUN STORED-PROCEDURE statement with and without the LOAD-RESULT-INTO phrase. • Detailed information about using the RUN STORED-PROCEDURE statement with the send-sql option. Examples to use the RUN STORED-PROCEDURE statement with and without the LOAD-RESULT-INTO phrase are provided. Complete syntax reference for Run Stored-Procedure The following syntax shows the RUN STORED-PROC statement and all options that can be used with the statement: Syntax RUN STORED-PROCEDURE procedure-name [[LOAD-RESULT-INTO [ = PROC-STATUS]] | [ = PROC-HANDLE]] [ NO-ERROR ] [([INPUT|OUTPUT|INPUT OUTPUT] [PARAM parameter-name =]expression, ... [INPUT|OUTPUT|INPUT OUTPUT] [PARAM parameter-name =]expression )] However, keep in mind that not all options shown can be used simultaneously. Note: In the RUN STORED-PROCEDURE syntax, note that the is either a pure handle or a handle that points to a temp-table. For more information about the use of temp-table handle with the LOAD-RESULT-INTO phrase, see the “LOAD-RESULT-INTO phrase” section on page 125. Syntax CLOSE STORED-PROCEDURE procedure-name [ integer-field = PROC-STATUS ] [ WHERE PROC-HANDLE = integer-field ] The CLOSE STORED-PROCEDURE is not used when the LOAD-RESULT-INTO keyword is used with the RUN-STORED-PROCEDURE statement. See the “Closed Stored-Procedure statement” section on page 127. For valid combinations and usage of these syntax elements see the: • “Run Stored-Proc statement execution without the LOAD-RESULT-INTO phrase” section on page 128 124 OpenEdge Data Management: DataServer for Microsoft SQL Server
Run Stored-Procedure details • “Run Stored-Proc statement execution with the LOAD-RESULT-INTO phrase” section on page 129. • “Run Stored-Proc statement execution using the send-sql-statement option” section on page 129. The following sections describe the syntax elements and options in detail. This section also presents examples that describe typical situations in which you might use the various options that the RUN STORED-PROC statement supports. Run Stored-Procedure statement The RUN STORED-PROC statement runs a RDBMS stored procedure or allows you to send Transact-SQL to a MS SQL Server based data source using an OpenEdge DataServer. It contains a procedure-name which is either the: • Name of the RDBMS stored procedure that you want to run • OpenEdge built-in procedure name, send–sql–statement, to send Transact-SQL to a MS SQL Server based data source Note: If your ABL procedure is in a transaction block when a RUN STORED–PROCEDURE statement is executed, the RDBMS stored procedure runs within the same RDBMS transaction, even if your stored procedure declares its own transaction levels. LOAD-RESULT-INTO phrase The LOAD-RESULT-INTO function loads the result sets into a temp-table which is represented by a handle variable. Note that handle can also be defined as extent to enable you to pass more than one temp-table handle in those instances where SQL statement(s) are defined to return more than one result set. When used with the RUN STORED-PROC statement or stored procedure to load result sets into temp-tables, this function carries an implicit CLOSE-STORED PROCEDURE statement. Note: The compiler issues an error at runtime if the variable of type handle with the LOAD-RESULT-INTO function does not point to a temp-table. For additional details about using the LOAD-RESULT-INTO phrase with the temp-table handle, see the “Loading result sets into temp-tables” section on page 141. When used with the LOAD-RESULT-INTO phrase, the temp-table handle identifies the temp-table to which the result set will be loaded. You can specify an array of one or more temp-table handle elements to retrieve stored procedure result sets and have the DataServer load the result set data directly into the associated temp-table(s). This approach allows you to have direct ABL access to the fields defined in the temp-table. OpenEdge Data Management: DataServer for Microsoft SQL Server 125
