    This example demonstrates how to prepare a statement with 
    <function>sqlsrv_prepare</function> and re-execute it multiple times (with 
    different parameter values) using <function>sqlsrv_execute</function>.

   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>.
