When you prepare a statement that uses variables as parameters, the variables
|
||
are bound to the statement. This means that if you update the values of the
|
||
variables, the next time you execute the statement it will run with updated
|
||
parameter values. For statements that you plan to execute only once, use
|
||
<span class="function"><a href="sqlsrv_query.html" class="function">sqlsrv_query()</a></span>.
