Changed Database Context To 'master' Error
a minute: Sign up php sql error message changed database context up vote 0 down vote favorite I have a routine that I call to do a mssql and mysql server connect like so: $mysql_aoi_conn = DoMySQLConnect( 'AOI' ); $mssql_aoi_conn = DoMsSQLConnect( 'itf' ); the functions are as follows: function DoMySQLConnect( $pdb_name ){ $mysql_conn = mysql_connect('localhost', '####', '####') or die( 'could user error message changed database context to not connect to localhost server : ' . mysql_error() ); $mysqldb_conn = mysql_select_db( $pdb_name, $mysql_conn ) or die('could not use database ' . $pdb_name . ' : ' . mysql_error() ); return array("database" => $mysqldb_conn, "connection" => $mysql_conn ); }; function DoMsSQLConnect( $pdb_name ){ $mssql_conn = mssql_connect("128.251.xxx.xxx", '###', '###') or die("failed to connect to server USLONSAPP003"); $mssqldb_conn = mssql_select_db( $pdb_name, $mssql_conn) or die("failed to select database " . $pdb_name); return array("database" => $mssqldb_conn, "connection" => $mssql_conn ); }; I'm trying to use the connection implementation within the mssql_query and mysql_query to tell my queries which connection to use but I'm getting an error. Here is one of my queries: $login_res = mssql_query("SELECT * FROM ITF_USER WHERE ITF_LOGIN = '" . $lcUserName . "'", $mssql_aoi_conn['connection'] ) or die("failed to query ITF_USER: \n" . mssql_get_last_message() ); This dies with the mssql_get_last_message() of: Changed database context to 'itf'. which is not really an error. Can someone tell me if I'm utilizing this query option wrong? php mysql sql-server error-handling share|improve this question edited Jun 28 '11 at 19:33 asked Jun 28 '11 at 19:16

UTC Modified: 2003-07-13 10:48 UTC From: cdcr440 at hotmail dot com Assigned: Status: Not a bug Package: MSSQL related PHP Version: 4.3.1 OS: WinNT Private report: No CVE-ID: View Add Comment Developer Edit [2003-07-07 12:01 UTC] cdcr440 https://bugs.php.net/bug.php?id=24522 at hotmail dot com Description: ------------ When selecting a database with mssql_select_db(), the error "Changed database context to 'XXX'". DB server is MSSQL 2000. The problem seems to be the result of running a query and the next time the script tries to select the database, it fails with the above message, which I wouldn't expect from mssql_query(). The failing query will first run for a long time and fail with the changed database above message. All subsequent attempts to select the database will fail with the same message. But running other queries in other scripts will be successful. The behaviour of the bug is hard to predict and I haven't been able to design a query that will surely generate the problem. Also the queries that fail with PHP work fine in SQL Analyzer/Enterprise manager (connected as the same user), so it's not a changed database context query/SQL problem. The user I use to connect to the database has the target database as default database therefore I wouldn't expect a change of context to be a problem. Also the user can run exactly the same query with a very slightly different value in one of the parameters and succeed(e.g. "hup" in the query for VARCHAR will fail but "hu" for the same column will succeed), so it's not an access right problem. However, the workaround I've found is to use the sa user to connect to the server, which would tend to show that it's a user problem. I thought for a while that it was a problem with number of open connections to the database, but I reduced them and the behaviour of the bug isn't consistent with that as it can occur when very few concurrent connections are open. The bug also has been present in the last few versions of PHP, not only in 4.3.1. I whish I could provide more useful information like a core dump, but the failing code is very simple, I haven't figured out what the problem is, and PHP doesn't crash.
