Question : Multiple schemas in MySql

Hi

Just wondering if anyone knows how to set up a connection to MySql to use several schemas, like DB2 on i5 with library list?
I have 2 schemas, and the application needs to look for table X in both of them, in preferred order. This is superior to specifying the schema in the SQL, since it allows the table to be moved around between the schemas, and still be found.

Hope someone knows, thanks.

Answer : Multiple schemas in MySql

Hi!
It's not important that the feature should be present in the MySQL. As far as I know, it's not there. But that's should not stop you to use the concept in case of MySQL also. Below is a code snippet that can help you.

             //$table_name is the table you may put in any schema
//$SQLString is the query you want to execute
//$schema1 is the first database
//$schema2 is the second database
//Considring you can handle the connection things and you got proper access right in both database.
 
function select_table($table_name,$SQLString,$schema1,$schema2..)
{
        $result=mysql_query("SHOW TABLES FROM $schema1")
        while($row=mysql_fetch_array($result)
        {
                if($row[0] == $table_name)
                {
                        return mysql_query($SQLString) or die mysql_error();
                }
        }
        $result=mysql_query("SHOW TABLES FROM $schema2")
        while($row=mysql_fetch_array($result)
        {
                if($row[0] == $table_name)
                {
                        return mysql_query($SQLString) or die mysql_error();
                }
        }
        return "any error code";
}
