If you have literals in your SQL statements, you need to make sure that the quote character matches your build settings or you could have problems binding the DBRM.
The SQL Option preprocessor defaults to the compiler setting for literals in the build settings. If you use the same character to enclose literals in your SQL statements as you did for COBOL literals, you don't have to do anything. If you use a different character for literals in SQL statements, then you have to use the preprocessor directive of either QUOTE or APOST.
