Comparing Text to Autonum in SQL

[sparkus]

Hey,

I'm trying to help someone out. They have a complicated table and decided to store autonumbers in a text field and attempt to join them up in SQL, but everytime I try to join I get a type mismatch error.....

I can only do it via Jet Sql....

Thanks!!!

Take a look at the Int or Val function.

Hope This Helps, PH.

Can you do that in the SQL statement????

 

[PHV]

Yes, even in the JOIN clause:
... FROM Table1 INNER JOIN Table2 ON Int(Table1.txtField) = Table2.AutoField ...

I still get a type mismatch....

SELECT test.*, links.*, test.primarykeyme
FROM links, test
WHERE(test.primarykeyme)=Int(links.encrypting_device);

 

[PHV]

What are the data type of test.primarykeyme and links.encrypting_device ?
Some sample values may help.

Crud,

He stuck some non-integer values into the textfield.....is there any way to convert the autonum to a text so I can get around this?

Thank you very much for your help!!!!!

Something like this ?
WHERE links.encrypting_device Like '*' & test.primarykeyme & '*';

WHERE links.encrypting_device Like '*' & test.primarykeyme & '*'

This is a little risky. If you have Text values that are substrings of other Text values (e.g. 111 and 11), they will both match an Autonum of 11.

You could use CStr(AutoNum) instead.
