Continuation for SQL statements in C and C++ applications that use SQL

You can split an SQL statement wherever a blank can appear. The backslash (\) can be used to continue a string constant or delimited identifier. Identifiers that are not delimited cannot be continued.

Constants containing DBCS data may be continued across multiple lines in two ways:

• If the character at the right margin of the continued line is a shift-in and the character at the left margin of the continuation line is a shift-out, then the shift characters located at the left and right margin are removed.

  This SQL statement has a valid graphic constant of G'<AABBCCDDEEFFGGHHIIJJKK>'. The redundant shifts at the margin are removed.

  *...+....1....+....2....+....3....+....4....+....5....+....6....+....7....*....8
  EXEC SQL SELECT * FROM GRAPHTAB           WHERE GRAPHCOL =  G'<AABBCCDDEEFFGGHH>
  <IIJJKK>';
   

• It is possible to place the shift characters outside of the margins. For this example, assume the margins are 5 and 75. This SQL statement has a valid graphic constant of G'<AABBCCDDEEFFGGHHIIJJKK>'.

  *...(....1....+....2....+....3....+....4....+....5....+....6....+....7....)....8
      EXEC SQL SELECT * FROM GRAPHTAB           WHERE GRAPHCOL =  G'<AABBCCDD>
     <EEFFGGHHIIJJKK>';
