| Is there anything special that I need to consider if I'm going to create a counter table that's single column, single row?It's for creating unique serial numbers for labeling, so a program will determine that it needs 20 labels, and will do do a SELECT Count_Num FROM COUNTTABLE and then use that as a base to start the labels and then do an UPDATE COUNTTABLE SET Count_Num = (SELECT Count_Num FROM COUNTTABLE)+20.So would it just be a:CREATE TABLE dbo.COUNTTABLE(Count_Num int) |

| Well, The select and update should be in the same transaction, or another transaction could get the same count_num (I am assuming that would be bad).-Chad |

| Good thinking, we only have one label printer and one person processing right now, but we'll be adding more at some point so probably a good idea. (As long as the labeling program can handle both at once...) |
