Hi there, I'm having a lot of trouble with one sql statement and I wonder can you help. I My problem is the following...there are two field name in the the table named LecturerName and Projectcode. Each ProjectCode vulue is unique within the table but there can be many entries in the table with the same LecturerName. I would like to pull each distinct value of LecturerName with any one corresponding ProjectCode value, it does not matter what the ProjectCode value is, but all attemps at this have failed so far. I have tried this but it does not work: Set rsLecturers = Server.CreateObject("ADODB.Recordset") sqlLect = "Select LecturerName, MIN(ProjectCode) from tblSuggestions WHERE LecturerName IN ( SELECT DISTINCT LecturerName FROM tblSuggestions)" rsLecturers.Open sqlLect, Conn, 3, 3 I get this error when I try to run this: [Microsoft][ODBC Microsoft Access Driver] You tried to execute a query that does not include the specified expression 'LecturerName' as part of an aggregate function. I am trying to put the results of this query into a recordset and I am using an accessdatabase Thanks in advance, Kevin.
