Chapter 3: RDBMS Stored Procedure Details The following types of temp-tables can support result sets: • Static — A temp-table whose schema is defined at compile time. • Dynamic — A temp-table whose schema is defined at run time. There are two types of dynamic temp-tables: dynamic-prepared and dynamic-unprepared. 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. PROC-STATUS phrase The PROC-STATUS phase returns the return status from a MS SQL Server stored procedure. The return status is an integer value that typically indicates whether a stored procedure succeeded or failed; if a stored procedure fails, a code indicates why it failed. See your Microsoft SQL Server documentation for descriptions of the possible values for the return status. PROC-HANDLE phrase The PROC-HANDLE phrase allows you to specify a handle to act as a unique identifier for a MS SQL DataServer stored procedure. For example, the PROC-HANDLE assigns a value to the specified integer field or variable (integer–field) that uniquely identifies the stored procedure that is returning results from MS SQL Server. Note these additional points about the PROC-HANDLE: • Progress Software Corporation recommends that you specify a procedure handle for each stored procedure that you run. • You do not have to specify a handle if there is only one active stored procedure and you do not include SQL statements in the OpenEdge application. NO-ERROR option The NO-ERROR option specifies that any ERROR condition that the RUN STORED–PROCEDURE statement produces is suppressed. Before you close a stored procedure, check the ERROR–STATUS handle for information on any errors that occurred. You receive an error when you attempt to close a stored procedure that did not start. Note: This option must appear before any runtime parameter list. PARAM phrase The Param phrase identifies a run-time parameter to be passed to the stored procedure. A parameter has the following syntax: Syntax [( [INPUT|OUTPUT|INPUT-OUTPUT ] [ PARAM parameter-name = ] expression, ... [INPUT|OUTPUT|INPUT-OUTPUT ][ PARAM parameter-name = ] expression )] 126 OpenEdge Data Management: DataServer for Microsoft SQL Server
Run Stored-Procedure details An expression is a constant, field name, variable name, or expression. INPUT is the default. OUTPUT and INPUT–OUTPUT parameters must be record fields or program variables. Note: When you run send–sql–statement for a MS SQL-based data source, it passes a single character expression parameter containing the SQL statement you want the data source to execute. If you do not specify parameter–name (the name of a keyword parameter defined by the stored procedure), you must supply all of the parameters in correct order. If you do specify parameter–name, you must precede your assignment statement with the keyword PARAM. If you do not supply a required parameter, and no default is specified in the stored procedure, you receive a run-time error. Closed Stored-Procedure statement For a RDBMS stored procedure, a PROC-STATUS received value indicates that the procedure has completed execution and makes available the return code value and any output parameters. For a send–sql–statement stored procedure, CLOSE STORED–PROCEDURE closes the SQL cursor used by the procedure, as shown: Syntax CLOSE STORED-PROCEDURE procedure-name [ integer-field = PROC-STATUS ] [ WHERE PROC-HANDLE = integer-field ] procedure The name of the stored procedure that you want to close or the built-in procedure name, send–sql–statement. integer–field = PROC–STATUS Assigns the return value from a stored procedure to the specified integer field or variable (integer–field). WHERE PROC–HANDLE = integer–field An integer field or variable whose value uniquely identifies the stored procedure that produces the results returned from the data source or the SQL cursor of a send–sql–statement stored procedure. Consider these points concerning the CLOSED STORED-PROCEDURE statement: • If you specified a PROC–HANDLE when you ran a stored procedure, you must specify the PROC–HANDLE when you close the stored procedure. • If you do not specify a PROC–HANDLE, the CLOSE STORED–PROCEDURE statement closes the procedure if there is only one stored procedure running. If there is more than one stored procedure running, an error is returned. OpenEdge Data Management: DataServer for Microsoft SQL Server 127
