With the exception of CREATE AUTHORIZATION and REPLACE AUTHORIZATION, a data definition statement is allowed in macro if it is the only SQL statement in that macro.

A data definition statement is not resolved until the macro is executed, at which time unqualified database object references are fully resolved using the default database of the user submitting the EXECUTE statement. If this is not the desired result, you must fully qualify all object references in a data definition statement in the macro body.

A macro can contain parameters that are substituted with data values each time the macro is executed. It also can include a USING modifier, which allows the parameters to be filled with data from an external source such as a disk file. A COLON character prefixes references to a parameter name in the macro. Parameters cannot be used for data object names.
