sSQL.Append( SELECT ‘X’ ); sSQL.Append( FROM ProfileInsurancePlanYear ); sSQL.Append( WHERE ProfileID = + profileid.ToString()

 sSQL.Append(" SELECT 'X' ");
        sSQL.Append(" FROM ProfileInsurancePlanYear ");
        sSQL.Append(" WHERE ProfileID = " + profileid.ToString() + " AND CropYear = " + cropyear.ToString());

This was a query that was originally hitting an access back end. I have moved it over to SQLCE and am perplexed about what this query is supposed to do.

The table structure it hits is:

ProfileID
InsurancePlanID
CropYear
INsurance_Price
Levels_XML

I am assuming this would select something from the Levels_XML column where the profileid and cropyear match?

Does this even work in sqlCE?

    This type of query is typically used to see if a row exists. If a row is found, the query will return a single character, X. Otherwise, it will be an empty result set… You could also say 

     sSQL.Append(" SELECT count(*) ");
 sSQL.Append(" FROM ProfileInsurancePlanYear ");
 sSQL.Append(" WHERE ProfileID = " + profileid.ToString() + 
             " AND CropYear = " + cropyear.ToString());

    Which will return a result with either 0 or some positive number. Different approaches both asking the database simply to indicate whether or not any records existing matching the condition.
