Preprocessor2 for Embedded SQL
Programming Reference

Each of the SQL statements embedded into a C application must begin with the SQL prefix EXEC SQL, which identifies the statement as an embedded SQL statement. The complete SQL prefix must appear on one line. The prefix is case insensitive, but no character other than blank can appear between EXEC and SQL. The remainder of the statement can appear on the same line or on the next and subsequent lines.

Subject to charset restrictions, SQL statements are case insensitive, except for host variable references. When dynamic SQL statement text is stored in a varchar host variable, the statement text cannot be longer than 64k.

Each embedded SQL statement must end with a semicolon.
