<p>
Assigns an DBMS client for the
connection.
</p>
<h3>Parameters</h3>
<P><EM>eSAClient.</EM> One of the following values
from <STRONG>SAClient_t</STRONG> enum:</P>
<UL><STRONG>
<LI><STRONG>SA_Oracle_Client</STRONG></STRONG> Oracle
client.<STRONG>
<LI><STRONG>SA_SQLServer_Client</STRONG></STRONG> SQL
Server client.<STRONG>
<LI><STRONG>SA_InterBase_Client</STRONG></STRONG>
InterBase client.<STRONG>
<LI><STRONG>SA_SQLBase_Client</STRONG></STRONG>
SQLBase client.<STRONG>
<LI>SA_ODBC_Client</STRONG> ODBC client.
<LI><STRONG>SA_DB2_Client</STRONG> DB2 client.
<LI><STRONG>SA_Informix_Client</STRONG> Informix client.
<LI><STRONG>SA_Sybase_Client</STRONG> Sybase client.
<LI><STRONG>SA_MySQL_Client</STRONG> MySQL client.
<LI><STRONG>SA_PostgreSQL_Client</STRONG> PostgreSQL client. </LI>
</UL>
<h3>Remarks</h3>
<p>
You can set a client in <A
href="Connection_Connect.html">Connect</A>
method, in this case you don't need to use
<STRONG>setClient</STRONG>
method. The main destination of this
method is to connect to a server with no connection to a database
(for example, to check a client availability and version). But if
you are calling <A
href="Connection_Connect.html">Connect</A>
method with no specified client you have to use
<STRONG>setClient</STRONG>
method
before.
</p>
<p>
If you are calling <STRONG>setClient</STRONG>
method when the connection is set to another client the previous
connection will be disconnected and new client will be
set.
