Begin each embedded SQL statement with the SQL prefix EXEC SQL, which identifies the statement as an embedded SQL statement. The complete SQL prefix must appear on one line and is not case specific. No character other than blank can appear between EXEC and SQL.The remainder of the statement can appear on the same line or on subsequent lines.
Subject to charset restrictions, SQL statements are case insensitive, with lower case variable definitions and references identical to their upper case equivalents.
End each embedded SQL statement with a semicolon, which is the SQL terminator. The embedded SQL statement text should not be over 64K.
