Sporadic errors

I have a page that lists 362 items with a checkbox. When the user completes an item,
he checks it and clicks the submit button, subsequently writing the values to a
database. The problem I need to solve is a better way to delete un-checked items from
the database. The more items the user completes, the longer the request object.
TIA, Mike

One of my users get this intermittently.

Now no for...next needed for DSQL !!!

And if you have a complete list of all possible checkbox values in some
other table, we can similarly fix your INSERT code, so you'd do it all in one
query and no loop used.

I did have to make a couple of minor changes, but works like a charm.

DSQL = "DELETE * FROM Worked " _
& " WHERE CALL = '" & SanCall & "' " _
& " AND ADIF NOT IN (" & cbs & ")"

and ADIF was a text field. I changed it to a number.

Well, it's clearly better to make it a number, but it *could* have worked as
a text field with a minor change:

cbs = resafe.Replace( cbs, "" )
cbs = "'" & Replace( cbs, ",", "','" )
DSQL = "DELETE * FROM Worked " _
& " WHERE CALL = '" & SanCall & "' " _
& " AND ADIF NOT IN (" & cbs & ")"

You see that? But then the resafe regexp would need to be changed, also, to
allow textual data instead of all numeric data.

p.s.: You really shouldn't use the asterisk following the word "delete" in
a DELETE query.

Access allows it, but it's not standard SQL and all other DBs will choke on
it.

Access works just fine if you omit it, so it's good practice to learn to
live without it.

Strange, Bob,

I thought an asterix would stand for "all fields"
while DELETE is about records?

Because if it is not about "all" what specific pointer[s] could be placed
after the DELETE, as records are defined by WHERE, and have no name?

SQL = "DELETE blah, blah1 from tblWorked" ?
