<div><p>SQL statements can be contained in one or more lines.</p>
|
||
<div class="section"><p>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.</p>
|
||
</div>
|
||
<div class="section"><p>Constants containing DBCS data may be continued across multiple
|
||
lines in two ways: </p>
|
||
<ul><li>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.
|
||
<p>This SQL statement has a valid graphic constant of G'<AABBCCDDEEFFGGHHIIJJKK>'.
|
||
The redundant shifts at the margin are removed. </p>

</li>
|
||
<li>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
