I took a little look at your code. The problem appears to be that the code grabs some attributes from the activeDrTbl and activeSrNo session keys, but these session attributes are missing. That’s what the two warnings are about.

These session variables are then used to construct the database query. But since the values are missing, an empty value is used in the query, which results in an invalid SQL statement. This results in the query failing and the page crashing.

I don’t know where or how those keys are supposed to be set, but they aren’t, so please make sure that these values are set properly.

And maybe validate that these properties are set correctly before putting them in the query. You’re only doing a SELECT query here, but writing something to the database like this can cause quite nasty corruption to the data in your database.
