This example demonstrates how to prepare a statement with

<function>sqlsrv_prepare</function> and re-execute it multiple times (with

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
|
|
<function>sqlsrv_query</function>.
