Hi!!

I'm having a problem( again) while creating a .dbf file. First, I have this line to create the table:
Create Table Results.dbf (BuyDate Date)

And this worked well.

Now, I've this line to add a date in the table:
Insert Into Results.dbf (20070922)

But it gives me a "Data type mismacth" error. I've already saw that the date format is YYYYMMDD. So where is the error here??

Just only ASCII text?? So why is there a Date format for .dbf file...??? I tried to insert '20070922', "20070922" and this didn't work as well...

I don't know exactly where that record is, in which table. So, cause I am a beginner in SQL server, with the knowledge what I have, I did this:
SELECT * FROM dbTest WHERE VALUES ='some value';

and it gives me error, near VALUES, so I don't know how to find it,

but that database has around 30 tables, and lots of records inside, so any help on some query, to find the text, like 'sometext' will be helpfull. Thanks for replying
