Thanks for the reply "value1/2" are not the acutal strings those are just placeholders. The string looks like this

value1="UID=rmdb_dbo;DBN=326474...."

(UID can have different usernames, I just picked rmdb_dbo as an example but it can also be a personal user like "cb2ayal" for example) value2 can be any SQL string like the below

"update ..." 
"insert ..."
"delete ..."

I am insterest in the tables with "rmdb_dbo" so I need to grep for this string
