<div class="section"><h4 class="sectiontitle">Purpose</h4> <p><samp class="codeph">SQLGetData()</samp> retrieves data
|
||
|
|
for a single column in the current row of the result set. This is an alternative
|
||
|
|
to <samp class="codeph">SQLBindCol()</samp>, which transfers data directly into application
|
||
|
|
variables on a call to <samp class="codeph">SQLFetch()</samp>. <samp class="codeph">SQLGetData()</samp> can
|
||
|
|
also be used to retrieve large character based data in pieces.</p>
|
||
|
|
<p><samp class="codeph">SQLFetch()</samp> must
|
||
|
|
be called before <samp class="codeph">SQLGetData()</samp>.</p>
|
||
|
|
<p>After calling <samp class="codeph">SQLGetData()</samp> for
|
||
|
|
each column, <samp class="codeph">SQLFetch()</samp> is called to retrieve the next row.</p>
|
||
|
|
<p><samp class="codeph">SQLGetData()</samp> is
|
||
|
|
identical to <samp class="codeph">SQLGetCol()</samp>, both functions are supported for
|
||
|
|
compatibility reasons.</p>
