It seems simple, but I need some help to write a query that will only select the first row (columns a,b,c,d,e) of a group of similar rows. Example: an employee can have one or more records (columns a is the employee number), but I only want to extract the first row for each employee. See below:

Table

Emp, Fname, Lname,itemNo, ItemDesc
1 joe smith 123 test part
1 joe smith 134 test part 2
1 joe smith 145 test part 3
2 bill white 111 partb
3 dave green 123 test part
3 dave green 111 partb

These are the rows I'm trying to extract:
1 joe smith 123 test part
2 bill white 111 partb
3 dave green 111 partb

Please help. Thanks!
