Doug,

Sorry I missed the datatype of your LabelsPrintedDTS col. yesterday (hat tip, Karen)!

I may be flogging a dead horse here but might you not simply add an integer column with a default value of 0 and update it to 1 after you print? So now you would use ... WHERE checkcolname = 0 for your selection.

But you're missing Doug's problem, Dan.  In order to populate the temp table, he would have to say "where Datecol is null", because those are the records that haven't been printed yet.  And Doug is saying that the "is null" is really slow

For my warehouse team, i create a temp table, open a form, and they double click or type in the part#s they want to print. Then the labels print based on the temp table.

 

No extra columns for your permanent tables and super fast.

That would work, Buddy.  Remember this column is not indexed, so the questions becomes:
What SELECTs multiple rows faster - a specific value or a null value?
Which is what Nicky's approach was asking.

What I have done in the past was set the default value to some off the date like 12/31/1899 then print your labels where the date = 12/31/1899

Nick:  His    LabelsPrintedDTS field is a DATETIME or DATE, as far as I can tell

Labels to be printed are selected WHERE LabelsPrintedDTS IS NULL.


Doug, when you create a new order, had you tried assigning a default value of 0 to LabelsPrintedDTS rather than no value? Once printed, you can change it to 1. This way you search on ... WHERE LabelsPrintedDTS = 0 rather than NULL.
