<div class="section"><h4 class="sectiontitle">Usage</h4><p>This function is used to return multiple results
|
|
that are set in a sequential manner upon the processing of a stored procedure
|
|
that contains SQL queries. The cursors have been left open so that the result
|
|
sets remain accessible when the stored procedure has finished processing.</p>
|
|
<p>After
|
|
completely processing the first result set, the application can call <samp class="codeph">SQLMoreResults()</samp> to
|
|
determine if another result set is available. If the current result set has
|
|
unfetched rows, <samp class="codeph">SQLMoreResults()</samp> discards them by closing
|
|
the cursor and, if another result set is available, returns SQL_SUCCESS.</p>
|
|
<p>If
|
|
all the result sets have been processed, <samp class="codeph">SQLMoreResults()</samp> returns
|
|
SQL_NO_DATA_FOUND.</p>
|
|
<p>If <samp class="codeph">SQLFreeStmt()</samp> is called with
|
|
the SQL_CLOSE or SQL_DROP option, all pending result sets on this statement
|
|
handle are discarded.</p>
