[AccessD] Hit the Wall?

Dan,

We gave them a choice, we limit the # of columns or upgrade to SQL.
They chose to limit the # of columns.
I'm pretty sure my colleague tried joining multiple tables (1-1) but the
query still choked on the 8K limit which
makes sense as a query is just a virtual table.  

Boolean fields are 2 bytes so you should be OK

regards

Michael M


Michael,

How did you split the table up and apply limits to the width of the
query? Did your form change sources as the users moved from one area to
another?

Unfortunately, there is no normalization I can do that would make any
sense, and wouldn't hurt the app.

I didn't know that queries has an 8K limit, but I hope I won't hit that.
Most of the fields are short text fields, or yes/no checkboxes.

Thanks!
Dan

No,

We hit this same problem and had to split the table up and apply limits
to the width of the query. Be careful with the 8K row limit as well, you
will likely run out of row space well before 255 columns.

Our client insisted they wanted to scroll sideways over 5 years of data,
displayed monthly with 6 columns per month.  Our prototype had vertical
scrolling but no no no we want it like Excel ;-)))

cheers

In an Access app w/FE and BE, I need a table that has about 270 fields.
A single form will be bound to the table.  (This is a business process
management application.)  If I upsize this to a project (never done
this), I can have up to 1024 fields in a table.

 

I tried creating a query to join two smaller tables, but queries are
also limited to 255 columns.

 

Is there a way around this so I can still use an Access BE?

 

Thanks!

Dan Waters
