<h1>Binding Input Parameters</h1>
</center>
<p>You should assign values for input variables
any time you want to execute an SQL command or a stored procedure with input parameters.</p>
<P>Suppose, we want to insert some rows into the table <EM
>EMPLOYEES ( NAME CHAR(25), AGE INTEGER, COMMENT CHAR(25)).</EM> In
the following examples we'll consider the different methods to write
the appropriated command text and bind input variables: </P>
<UL>
<LI><A
href="bind.html#Assigning a value with SAParam object">assigning
a value to <STRONG>SAParam</STRONG>
object</A>;
<LI><A href="bind.html#Using the stream operator<<" >using the
stream <STRONG>operator<<</STRONG></A>.</LI></UL>
<H2><A name="Assigning a value with SAParam object">Assigning a value with SAParam object</A><A name="Assigning a value with SAParam object">
</A></A></H2>
<P><A href="../OnLineDoc/Param.html">SAParam</A> object represents a
parameter object associated with a command.</P>
<H3>Example 1. </H3>
<P>Let's execute the next SQL command to insert a row into the
table:</P>
<P><EM>insert into
EMPLOYEES (NAME, AGE, COMMENT) values (:1, :2, :3)</EM></P>
<P>This command has three input parameters to set values to
<EM>NAME, AGE</EM> and <EM>COMMENT</EM> columns. In that example input parameters
are marked by <EM>:1, :2, :3</EM>. It means we will identify a
parameter by its <STRONG>position</STRONG> . </P>
<P>To create and execute the command we should do the following:</P>
<OL>
<LI>Create a command object <EM>cmd</EM>
