<p>SQL statements can be coded in a PL/I program wherever executable statements

can appear.</p>
|

|
|
<p>Each SQL statement in a PL/I program must begin with EXEC SQL and end with

a semicolon (;). The key words EXEC SQL must appear all on one line, but the

remainder of the statement can appear on the next and subsequent lines.</p>

<li class="ulchildlink"><strong><a href="rzajpcommentspli.htm">Comments in PL/I applications that use SQL</a></strong><br />

The line continuation rules for SQL statements are the same as those for other PL/I statements, except that EXEC SQL must be specified within one line.</li>

<li class="ulchildlink"><strong><a href="rzajpincludecodepli.htm">Include code in PL/I applications that use SQL</a></strong><br />

SQL statements or PL/I host variable declaration statements can be included by placing the following SQL statement at the point in the source code where the statements are to be embedded.</li>

Code SQL statements within the margins specified by the MARGINS parameter on the CRTSQLPLI command. If EXEC SQL does not start within the specified margins, the SQL precompiler will not recognize the SQL statement.</li>
