f2s_esql_get_proc_param¶

Applies to: Oracle, MS SQL, MySql/MariaDB, PostgreSQL Drivers

Syntax

f2s_esql_get_proc_param {parameterNumber OR parameterName} to {variable} [using {variant}]

Parameter	Description
parameterNumber	The position of the parameter (1 - iNUM) to return
parameterName	A string containing the name of the parameter
variable	Variable to hold the value of the parameter
variant	Optional variant type variable that will receive a statement interface

Description

This command is used to get the value of a specific parameter associated with a stored procedure.

The optional “using” syntax allows you to pass around the interface created by this command. The variable passed MUST be a variant. This allows for multiple statements to be active concurrently in some cases. If you use the “using” syntax, it must be used on all subsequent commands. Mixing the using syntax is not supported. So for instance, if you plan on having multiple statements active concurrently, all active statements must make use of the using syntax.

Examples

SQL Server Code to create a simple Stored Procedure ‘dbo.TEST’ that takes a ‘DATETIME’ input and adds 40 days to the ‘OUTPUT’ parameter

CREATE PROCEDURE TEST @dDateIN DATETIME, @dDateOUT DATETIME OUTPUT
 AS SELECT @dDateOUT = DATEADD(dd,40,@dDateIN)

DataFlex code to call the SQL Server ‘TEST’ Stored Procedure under the ‘.dbo’ schema

DateTime dtCurrentDateTime
DateTime dtOutputDateTime
Move (CurrentDateTime()) to dtCurrentDateTime

f2s_esql_set_proc_name "dbo.TEST"
f2s_esql_prepare_stmt
f2s_esql_set_proc_param "@dDateIN" to dtCurrentDateTime
f2s_esql_execute_proc
f2s_esql_get_proc_param "@dDateOUT" to dtOutputDateTime
Showln  dtOutputDateTime
