Continuation for SQL statements in ILE RPG applications that use SQL

Start of change This topic introduces the continuation for SQL statements in two types of RPG format. End of change

Fixed-form RPG

When additional records are needed to contain the SQL statement, positions 9 through 80 can be used. Position 7 must be a + (plus sign), and position 8 must be blank. Position 80 of the continued line is concatenated with position 9 of the continuation line.

Constants containing DBCS data can be continued across multiple lines by placing the shift-in character in position 81 of the continued line and placing the shift-out character in position 8 of the continuation line.

In this example the SQL statement has a valid graphic constant of G'<AABBCCDDEEFFGGHHIIJJKK>'.

 
C/EXEC SQL    SELECT  *  FROM  GRAPHTAB  WHERE  GRAPHCOL  =   G'<AABBCCDDEE>
C+<FFGGHHIIJJKK>'
C/END-EXEC

Free-form RPG

SQL statements can be contained on one or more lines. To continue an SQL statement across multiple lines, the SQL statement can be split wherever a blank is allowed. The plus sign (+) can be used to indicate a continuation of a string constant. The literal continues with the first nonblank character on the next line.
