<h1>PostgreSQL</h1>
<P align=left>SQLAPI++ allows to work with a number of SQL database
servers. It provides common mechanisms to access database, and as a
general rule they work for any database server. But each server has
some specific features which developer has to know to use all
server's capability and avoid potential errors.</P>
<P align=left>This page collects all <STRONG>specific</STRONG> information that concerns
working with <STRONG>PostgreSQL</STRONG>
server using SQLAPI++
Library. Full information about using SQLAPI++ see in <A
href="../HowTo/index.html">How To</A>
and <A
href="../OnLineDoc/index.html">Online Documentation</A>.

<p>To connect to a database you should create a
connection object and then connect it. A connection object is
represented by <A href="../OnLineDoc/Connection.html" >SAConnection</A>
class. After the connection is created you need to connect it to
<STRONG>PostgreSQL</STRONG>
server using <A href="../OnLineDoc/Connection_Connect.html" >SAConnection::Connect</A>
method</p>
<p><font face=Arial><b
>void Connect( const SAString

&</b>sUserID<b>, const SAString
&</b>sPassword<b>, SAClient_t</b>
eSAClient<b> =

> <BR></b></font></p>
<p>with the following parameters:</p>
<P><EM>sDBString.</EM> One of the following
formats:</P>
<UL>
<LI><STRONG>"" or "@"</STRONG> - empty
string or '@' character, connects to a local server.
<LI>
<STRONG><database name> or @
<STRONG><database name></STRONG></STRONG> - connects to
a database with the specified name on local server.<LI>
<STRONG><server name>@</STRONG> - connects to the specified
server.<LI><STRONG><server

</STRONG>- connects to a database
with the specified name on the specified server.</LI></UL>
<P><EM>sUserID.</EM> A string containing a user name
to use when establishing the connection.<BR><EM>sPassword.</EM> A string containing a
password to use when establishing the connection.<BR><EM>eSAClient.</EM> Optional. One of the
following values from <STRONG>SAClient_t</STRONG> enum:
<UL>
<LI><STRONG>SA_PostgreSQL_Client</STRONG>
PostgreSQL client.
<LI><STRONG>SA_Client_NotSpecified</STRONG>
Used by default if <EM>eSAClient</EM>parameter is
omitted. You can use this default value only if you have
call <A

method with <STRONG>SA_PostgreSQL_Client</STRONG>
constant before.</LI>
