Default Parameters in a Stored Procedure Hook

In OneData, you can specify the parameters to the external program or stored procedure when you define the hook or assign it to an object. Parameters defined when the hook is assigned to an object, the parameters override the parameters in the hook definition.

You can use static parameters as needed. You can also pass any other constant numeric parameters to the procedure other than the following placeholders.

Note: The following rules apply to parameters:

Parameters are not case sensitive and must be separated by commas.

The format for dates in the XML data stream is YYYY-MM-DD HH24:MI:SS.

The XML stream publishes BLOB and CLOB as null values.
