Table filter strange problem

AST · 2007-07-10

Hi,
Maybe someone had similar problem.
I have two identical tables:
- on local sql server (Table Filter works fine)
- on remote sql server (Table Filter doesn't work - omit some records)
I use the following combinations of filter:
Field1 (Boolean): Yes
Field2 (Boolean): No

I have the same properties of sql server, database and table and I use the same collation.
:?:

How did you tested that?

I just created one table on local server and exported it to remote server. I have the same data in both of tables. I tested 2 fileds of boolean type. On local server Table Filter works good but on remote server doesnt't work even in sipmle case (doesn't show all records which satisfy the conditions).
Example: I know that there are 8 records that meet conditions and I Navision show only 5.

Try to look at the records directly to SQL. Check if there are correct values 0/1 instead false/true...

I solved my problem

Becouse I didn't insert value to my table directly, but using outside application, I set sql property Allows Null to Yes (I didn't need import default values to this table). So I had NULL value insted of 0. Navision doesn't know NULL value?

The trick I use for NULL is this.

If I want to filter for true, I set the following filter

setfilter(MYField,'<>%1',true);

this will include false, as well as NULL.

If I want to filter on false

setfilter(MYField,'<>%1',false);

This includes true as well as NULL.

And this might help for finding NULL, I suppose?

SETFILTER("The Boolean",'<>%1&<>%2',TRUE,FALSE);

Howdy, Stranger!
