I have installed a UDF dll on my firebird database, however i am unsure how to call it.
The UDF creates a text file to a location, and is called FILE_WRITE:
DECLARE EXTERNAL FUNCTION FILE_WRITE
RETURNS INTEGER BY VALUE
ENTRY_POINT 'File_write' MODULE_NAME 'udf_file.dll';
Could someone please advise on the syntax of calling a UDF via a trigger please?
