<h1 class="topictitle1">DB2 UDB
|
|
CLI SQLSTATEs</h1>
|
|
<div><p>Because different database servers often have different diagnostic message
|
|
codes, DB2<sup>®</sup> UDB
|
|
CLI provides a standard set of <em>SQLSTATEs</em> that are defined by the X/Open
|
|
SQL CAE specification. This allows consistent message handling across different
|
|
database servers.</p>
|
|
<div class="p">SQLSTATEs are alphanumeric strings
|
|
of 5 characters (bytes) with a format of <samp class="codeph">ccsss</samp>, where <samp class="codeph">cc</samp> indicates
|
|
class and <samp class="codeph">sss</samp> indicates subclass. Any SQLSTATE that has a
|
|
class of: <ul><li>01, is a warning.</li>
|
|
<li>HY, is generated by the CLI driver (either DB2 UDB CLI or ODBC).</li>
|
|
</ul>
|
|
</div>
|
|
<p>The <samp class="codeph">SQLError()</samp> function also returns an
|
|
error code if the code is generated by the server. When connected to an IBM<sup>®</sup> database
|
|
server, the error code is SQLCODE. If the code is generated by DB2 UDB CLI instead
|
|
of at the server, then the error code is set to -99999.</p>
|
|
<p>DB2 UDB
|
|
CLI SQLSTATEs include both additional IBM defined SQLSTATEs that are returned
|
|
by the database server, and DB2 UDB CLI defined SQLSTATEs for conditions that are
|
|
not defined in the X/Open specification. This allows for the maximum amount
|
|
of diagnostic information to be returned. When running applications in Windows<sup>®</sup> using
|
|
ODBC, it is also possible to receive ODBC defined SQLSTATEs.</p>
|
|
<div class="p">Follow these
|
|
guidelines for using SQLSTATEs within your application: <ul><li>Always check the function return code before calling <samp class="codeph">SQLError()</samp> to
|
|
determine if diagnostic information is available.</li>
|
|
<li>Use the SQLSTATEs rather than the error code.</li>
|
|
<li>To increase your application's portability, only build dependencies on
|
|
the subset of DB2 UDB
|
|
CLI SQLSTATEs that are defined by the X/Open specification, and return the
|
|
additional ones as information only. (Dependencies refers to the application
|
|
making logic flow decisions based on specific SQLSTATEs.)</li>
|
|
<li>For maximum diagnostic information, return the text message along with
|
|
the SQLSTATE (if applicable, the text message includes the IBM defined
|
|
SQLSTATE). It is also useful for the application to print out the name of
|
|
the function that returned the error.</li>
