Calling a procedure or function with DEFAULT parameter values
In T-SQL, you can pass the DEFAULT keyword in a call to a procedure or function to indicate that the default value of the parameter, as specified in the declaration of the procedure or function, should be used in the call. Babelfish doesn’t support the DEFAULT keyword in procedure or function calls.
You can run Babelfish Compass with the -rewrite option on SQL source files containing procedure and function calls. Babelfish Compass rewrites the calls with actual default parameter values in place of the DEFAULT keyword. Each literal value that replaces a DEFAULT keyword is preceded and followed by comments that identify which parameters represent default values. If you change the default value of the parameter in the declaration of the procedure or function, you should update the old parameter values with which the DEFAULT keyword has been replace for all calls to that procedure or function.
–Before rewrite
dbo.stored_procedure_1( @variable1, parameter_value, DEFAULT, DEFAULT, DEFAULT)
–After Babelfish Compass rewrite
dbo.stored_procedure_1( @variable1, parameter_value, /*REWRITTEN*/ 'N/A' /*DEFAULT*/,
/*REWRITTEN*/ NULL /*DEFAULT*/, /*REWRITTEN*/ 0 /*DEFAULT*/)
