<h1 class="topictitle1">String truncation in DB2 UDB CLI functions</h1>
|
|
<div><p>If an output string does not fit into a buffer, DB2<sup>®</sup> UDB CLI truncates the string to a length
|
|
that is one less than the size of the buffer, and writes the null terminator.
|
|
If truncation occurs, the function returns SQL_SUCCESS_WITH_INFO and an SQLSTATE
|
|
by indicating truncation. The application can then compare the buffer length
|
|
to the output length to determine which string is truncated.</p>
|
|
<p>For example, if <samp class="codeph">SQLFetch()</samp> returns SQL_SUCCESS_WITH_INFO,
|
|
and an SQLSTATE of 01004, at least one of the buffers bound to a column is
|
|
too small to hold the data. For each buffer that is bound to a column, the
|
|
application can compare the buffer length with the output length and determine
|
|
which column is truncated.</p>
