CODBCStmt.SetStmtAppParamDescmethod

Sets the handle to the APD for subsequent calls to **Execute** and **ExecDirect** on the statement handle.

Syntax

FUNCTION SetStmtAppParamDesc (BYVAL dwAttr AS SQLUINTEGER) AS SQLRETURN

Parameters

Return value

SQL_SUCCESS, SQL_SUCCESS_WITH_INFO, SQL_ERROR, or SQL_INVALID_HANDLE.

Description

Sets the handle to the APD for subsequent calls to Execute and ExecDirect on the statement handle. The initial value of this attribute is the descriptor implicitly allocated when the statement was initially allocated. If the value of this attribute is set to SQL_NULL_DESC or the handle originally allocated for the descriptor, an explicitly allocated APD handle that was previously associated with the statement handle is dissociated from it and the statement handle reverts to the implicitly allocated APD handle.

This attribute cannot be set to a descriptor handle that was implicitly allocated for another statement or to another descriptor handle that was implicitly set on the same statement; implicitly allocated descriptor handles cannot be associated with more than one statement or descriptor handle.
