Query Language for Java™ (SQLJ) support is based on the SQLJ
|

|
|
ANSI standard. The DB2 SQLJ support is contained in the IBM<sup>®</sup> Developer
|
||
|
|
Kit for Java. DB2 SQLJ support allows you to create, build, and run
|
||
|
|
embedded SQL for Java applications.</p>
|
||
|
|
<p>The SQLJ support provided by the IBM Developer Kit for Java includes
|
||
|
|
the SQLJ run-time classes, and is available in /QIBM/ProdData/Java400/ext/runtime.zip.</p>
|
||
|
|
<div class="section"><h4 class="sectiontitle">SQLJ setup</h4><p>Before you can use SQLJ in Java applications
|
||
|
|
on your server, you need to prepare your server to use SQLJ. For more information,

see <a href="sqljsetup.htm#sqljsetup">Setting up your server to use SQLJ</a>.</p>

restrictions</h4><p>When you create DB2 applications with SQLJ, you should be
|
||
|
|
aware of the following restrictions:</p>
|
||
|
|
<ul><li>DB2 SQLJ
|
||
|
|
support adheres to standard DB2 Universal Database™ restrictions
|
||
|
|
on issuing SQL statements.</li>
|
||
|
|
<li>The DB2 SQLJ
|
||
|
|
profile customizer should only be run on profiles associated with connections
|
||
|
|
to the local database.</li>
|
||
|
|
<li>The SQLJ Reference Implementation requires JDK 1.1, or higher. See <a href="multjdk.htm">Support for multiple Java Development Kits (JDKs)</a> for
|
||
|
|
more information on running multiple versions of the Java Development
|
||
|
|
Kit.</li>

<li class="ulchildlink"><strong><a href="sqljprof.htm">Structured Query Language for Java profiles</a></strong><br />
|
||
|
|
Profiles are generated by the SQLJ Translator, sqlj, when you translate the SQLJ source file. Profiles are serialized binary files. That is why these files have a .ser extension. These files contain the SQL statements from the associated SQLJ source file.</li>
|
||
|
|
<li class="ulchildlink"><strong><a href="sqlj.htm">The structured query language for Java (SQLJ) translator (sqlj)</a></strong><br />
|

The SQLJ translator, sqlj, generates a serialized profile containing information about the SQL operations found in the SQLJ program. The SQLJ translator uses the /QIBM/ProdData/Java400/ext/translator.zip file.</li>

<li class="ulchildlink"><strong><a href="sqljdbpc.htm">Precompile SQL statements in a profile using the DB2 SQLJ profile customizer, db2profc</a></strong><br />

You can use the DB2 SQLJ Profile Customizer, db2profc, to make your Java application
|

|

work more efficiently with your database.</li>

<li class="ulchildlink"><strong><a href="sqljdbpp.htm">Print the contents of DB2 SQLJ profiles (db2profp and profp)</a></strong><br />
|
||
|
|
The DB2 SQLJ
|
||
|
|
Profile Printer, db2profp, prints the contents of a DB2 customized profile in plain text. The
|
||
|
|
Profile Printer, profp, prints the contents of profiles generated by the SQLJ

translator in plain text.</li>
|
||
|
|
<li class="ulchildlink"><strong><a href="sqljpdb.htm">SQLJ profile auditor installer (profdb)</a></strong><br />
|
||
|
|
The SQLJ profile auditor installer (profdb) installs and uninstalls debugging class-auditors. The debugging class-auditors are installed into an existing set of binary profiles. Once the debugging class-auditors are installed, all RTStatement and RTResultSet calls made during application run time are logged. They can be logged to a file or standard output. The logs can then be inspected to verify the behavior and trace errors of the application. Note that only the calls made to the underlying RTStatement and RTResultSetcall interface at run time are audited.</li>

|
|
<li class="ulchildlink"><strong><a href="sqljpc.htm">Convert a serialized profile instance to Java class format using the SQLJ profile conversion tool (profconv)</a></strong><br />
|
||
|
|
The SQLJ profile conversion tool (profconv) converts a serialized
|
||
|
|
profile instance to Java class format. The profconv tool is
|
||
|
|
needed because some browsers do not support loading a serialized object from
|
||
|
|
a resource file that is associated with an applet. Run the profconv utility
|
||
|
|
to perform the conversion.</li>

||
|
|
<li class="ulchildlink"><strong><a href="sqljembd.htm">Embed SQL statements in your Java application</a></strong><br />
|
||
|
|
Static SQL statements in SQLJ are in SQLJ clauses. SQLJ clauses
|
||
|
|
begin with <samp class="codeph">#sql</samp> and end with a semicolon (;) character.</li>
|
||
|
|
<li class="ulchildlink"><strong><a href="sqljcr.htm">Compile and run SQLJ programs</a></strong><br />
|

|

If you Java program has embedded SQLJ statements, you need

|
|
to follow a special procedure to compile and run it.</li>
