Home -> Community -> Mailing Lists -> Oracle-L -> Re: Bind Variables
Danny,
I'll bet my morning cheese danish that when you changed the SQL from using literals to bind variables, the execution plan changed.
Just pull each SQL statement and run it in SQL*Plus, one version of it with literals and the other with bind variables. The difference in your web page coming up in < 2 seconds with literals and > 5 minutes with bind variables is huge. Testing like this in SQL*Plus should reveal which SQL statement is taking longer with bind variables.
In SQL*Plus use SET AUTOTRACE ON so you can see the execution plans. Once you find the problem you can use hints to force the bind variable version to use the same fast plan that was used by the literal version.
