Usage notes:
CLI applications always requests describe information from the server, ignoring the binding information that is provided by the application. Setting the ForceDescribeBeforeCall keyword to 1 also sets the AllowDeferredPrepare keyword to 0, which means that describe information is also requested for dynamic SQL statements. Setting the AllowDeferredPrepare keyword to 0 does not set the ForceDescribeBeforeCall keyword to 1.
CLI applications do not request describe information from the server and uses the binding information that is provided by the application when it prepares a CALL statement. If the CALL statement fails, the error recovery logic implicitly requests the describe information of input parameters from the server and issues the CALL statement again.
