Parameter Markers in Procedure Calls

When calling procedures that accept parameters, interoperable applications should use parameter markers instead of literal parameter values. Some data sources do not support the use of literal parameter values in procedure calls. For more information about parameters, see Statement Parameters. For more information about calling procedures, see Procedure Calls, later in this section.
