<div><p>An SQL statement can be placed anywhere a REXX command can be placed.</p>
|
||
<div class="section"><p>Each SQL statement in a REXX procedure must begin with EXECSQL
|
||
(in any combination of uppercase and lowercase letters), followed by either:</p>
|
||
<ul><li>The SQL statement enclosed in single or double quotation marks, or</li>
|
||
<li>A REXX variable containing the statement. Note that a colon must not precede
|
||
a REXX variable when it contains an SQL statement.</li>
|
||
</ul>
|
||
</div>
|
||
<div class="section"><p>For example:</p>
|
||
<pre>EXECSQL “COMMIT”</pre>
|
||
<p> is
|
||
equivalent to:</p>
|
||
<pre>rexxvar = “COMMIT”
|
||
EXECSQL rexxvar</pre>
|

</div>
|

<div class="section"><p>The command follows normal REXX rules. For example, it can optionally
|
||
be followed by a semicolon (;) to allow a single line to contain more than
|
||
one REXX statement. REXX also permits command names to be included within
|
||
single quotation marks, for example:</p>
|

<pre>'EXECSQL COMMIT'</pre>
