ASP Search
I am trying to build a search results page for the user. In the database we have three tables Employees Empname - Text Fullname - Text Records Id - Autonumber Subject - Text Description - Text Record Dependents RecordId - Integer Username - Text In record dependents there could be multiple values for each recordid basically it specifies who is allow to view a particular record. What I need help with is how do a search that will find what the user has specified but only bring back results for which he is a RecordDependent. Can this be done through simple sql? or do I need something more. I was thinking more on the lines of "Select * from records where exists (Select * from recorddependents where empname = '8877YYYY') and description ='" & request.form("description") & "'" First of all, don't use "Select *"
http://aspfaq.com/show.asp?id 96 Second, try something along the lines of; strSQL = "Select [FIELDS] from Records Where [Condition 1]=[Value 1] AND [Condition 2]=[Value 2]" Replacing [FIELDS] with your field names, and [Condition 1] etc, with the respective conditions and values you want to meet.

based on the results of another query (QueryA): QueryA = "SELECT CustID FROM tblCUSTOMERS WHERE CustName = 'A%'" QueryB = "SELECT CustID, CustName FROM tblCUSTOMERS WHERE CustID IN (" & QueryA & ")" But the following is even faster and allows for more than one field to be returned in QueryA: QueryB = "SELECT tblCUSTOMERS.CustID, CustName FROM (" & strSQLA & ") AS tblSQLA INNER JOIN tblCUSTOMERS ON tblSQLA.CustID = tblCUSTOMERS.CustID" So QueryA would include all the CustID's for customers starting with A. And QueryB would include more fields in the customers table (i.e. not just the CustID field) for the records returned in QueryA (which was the customers starting with A). I suppose it wouldn't hurt to always use LEFT JOIN's in QueryB and build from the tblSQLA on the left to other tables that have fields you want to return. Best regards, J.
