I am using SQL Server 2008. I am runnung a SQL statement against several
tables. The data for the most part is all stored in varchar fields. I
cannot change the datatypes. it is a commercial application and I would
break it. Anyway one of the fields (Add_Date) stores a date like this
11/22/2009. I need records where this field has a date value in it. Problem
with using not null or not "" is there are some values stored as amounts as
well $ 123.45 0.00 123.00. How could I get only the records with a date
value in this field?

Thanks

Try the ISDATE function:

WHERE ISDATE(AddDate) = 1

Plamen:

That filterd out the amounts. I found out there is another set of values in
percents 10%. I tried DateField NOT IN ('%') but is still shows up. Any
ideas?

TIA

I though this is what you want. You asked to select only valid date
values and this is what ISDATE does. For amounts you can check with
ISNUMERIC.

So what kind of "wrong" data still shows up after putting it through
ISDATE? Do you have examples?
