<div class="section"><h4 class="sectiontitle">Purpose</h4> <p><samp class="codeph">SQLCancel()</samp> attempts to
|
|
end the processing of an ongoing SQL statement operation that is executing
|
|
synchronously. To cancel the function, the application calls <samp class="codeph">SQLCancel()</samp> with
|
|
the same statement handle that is used by the target function, but on a different
|
|
thread. How the function is canceled depends on the operating
|
|
system.</p>
