When you use DISTINCT in a Select statement, you are saying that you only want one row in the result set for each distinct set of values. The result set will not have any two rows that have the same values in every column.
Let's say in table SOP30300, you have the following data:
INV001 Items: ABC, DEF, GHI
INV002 Items: DEF, JKL, MNO
INV003 Items: MNO
Then you run this statement:
SELECT DISTINCT itemnmbr
FROM dbo.SOP30300
The result set should be:
ABC,DEF,GHI,JKL,MNO
