Hey guys, I would really appriciate it if someone can direct me with this problem. On my laptop I have: Windows XP Professional, Oracle 9i Database, Oracle Client Software, PHP4.3.1, and Apache server. PHP and Apache work fine. Oracle i9 by itslef works fine too. However when i tried to connect from PHP to Oracle using the following code: ---Code Start------------------------------------------------- <?php $user ="netuser"; $upasswd ="netuser"; $dsn ="CSSD"; $conn = odbc_connect($dsn,$user,$upasswd); echo "conn: $conn"; if ($conn <= 0) { echo "Error in connection<BR>"; exit; } else { echo "<P>Connection successful\n"; } odbc_Close($conn); ?> ----Code End------------------------------------------------------ I get the following error: xxxxxxxxxxError Start xxxxxxxxxxxxxxxxxxxx Warning: SQL error: [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified, SQL state IM002 in SQLConnect in C:\Documents and Settings\Administrator\My Documents\php\project\php14.tmp on line 5 conn: Error in connection xxxxxxxxxxError End xxxxxxxxxxxxxxxxxxxx I have already set up the ODBC by going to Administrative Tools -> Data Sources (ODBC) -> User DSN -> and added an "Oracle in OraHome92" driver for my database. Please help me out guys. This is for my Master's Thesis project. Appriciated, Yousef --------------------------------- Do you Yahoo!? Free online calendar with sync to Outlook(TM).
