Can some please help me with a duplicate key error

[mike browne]

Hello,

I have been trying to solve this problem for a long time and have not found a solution, so could someone please assist me.

I am getting this error:

[MySQL][ODBC 3.51 Driver][mysqld-4.1.22-community-nt]Duplicate entry '' for key 2


Now as far as I know I only have one index on the table and it is the primary key which is auto-increment. So what is this error really telling me, what is it referring to when it says "For Key 2", I cannot figure out what key2 is.

Also, it shows as a '' which to me looks like a null. However I have every field filled in with something on the insert clause.

Insert clause is:

INSERT INTO ASSETSCHEDULE (AssetID,DateReserved,DateReservedString,CreatDate,CreatDateString,CreatTime,CreatTimeString,TimeReserved,TimeReservedString,ReserveLength,LastRecordedTime,LastRecordedTimeString,PatronBarcode,PatronFirstName,PatronLastName,PatronType,ReserveType,BookingCode,RecordDeleted,BranchLocated,ZoneLocated) VALUES('Table7',41409,'5/15/2013',41409,'5/15/2013',0.59880594907,'2:22:16 PM',0.59791666667,'2:21:00 PM',60,0.59791666667,'2:21:00 PM','Temp Schedule ',' ',' ',' ',1,'T8DJ9B350E7OO23',2,'Main Room',0)

I am at a loss for why this would error off with the above error message. So can someone please assist me, or tell me what to look for.

Thanks for any information

Mike
