<h1 class="topictitle1">ODBC API return codes</h1>
|
|
<div><p>Every ODBC API function returns a value of type SQLRETURN (a short
|
|
integer). There are seven possible return codes, and associated with each
|
|
is a manifest constant.</p>
|
|
<div class="section"><p>The following list provides an explanation of each particular
|
|
code. Some return codes can be interpreted as an error on the function call.
|
|
Others indicate success. Still others indicate that more information is needed
|
|
or pending.</p>
|
|
</div>
|
|
<div class="section"><p>A particular function may not return all possible codes. See the <em>Microsoft<sup>®</sup> ODBC
|
|
3.0 Software Development Kit and Programmer's Reference, Version 3.0 ISBN
|
|
1-57231-516-4.</em> for possible values, and for the precise interpretation
|
|
for that function.</p>
|
|
</div>
|
|
<div class="section"><p>Pay close attention to return codes in your program, particularly
|
|
those that are associated with the processing of SQL statements processing
|
|
and with data source data access. In many instances the return code is the
|
|
only reliable way of determining the success of a function.</p>
