SQL Query Check And Validate (Urgent)

Hello All,

It seems the following queries are causing my DB connections to time out, but I cant seem to figure out why.

These queries reside within my xml.config file.

The connection to the DB is fine and live. I get timeout errors every few hours or so.

Can anyone take a look at the queries which I pasted below and tell me why I keep getting timeout errors? PLEASE, I need all the help I can get.

<query name="Products" rowElementName="Product">
