Hello,
I have a table that has a string field "ANUM" that has values that always begin with 089. Then the 3 characters; 089, are followed by between 3 or 4 characters. So a typical value in this field might be 089213 or 0895146. There will never be more than 4 characters, which follows that the total number of characters will not exceed 7.
What I need is an expression that will "filter" out the 089 values, leaving the remainder behind. So the aforementioned values of 089213 and 0895146 would result, after the expression is run, in 213 and 5146, respectively.
Thanks in advance for your replies!
Phil

I would use -
Right(Str(intVariable), len(Str(intVariable)) - 3)
-
If you specifically need the value returned as an integer instead of a string, you can use -
Val(Right(Str(intVariable), len(Str(intVariable)) - 3))
-
Verbose Explination: str(strVariable ) returns the number stored in intVariable as a string (so if intVariable = 0891234, str(intVariable = "0891234")
That value is then passed to the len() function which returns the strings length (len("0891234") = 7)
Then 3 is subtracted from it (7 - 3 = 4)
So what we now have is this:Val(Right("0891 234", 4)) which returns the first 4 characters in "0891234" counting from the right [starting form the 4 in other words] (this returns "1234")
Finally, val() turns "1234" back into a number 1234. Condensed Explination: intVariable = 0891234 Val(Right(Str(i ntVariable), len(Str(intVari able)) - 3)) Val(Right(Str(0 891234), len(Str(0891234 )) - 3)) Val(Right("0891 234", len("0891234") - 3)) Val(Right("0891 234", 7 - 3)) Val(Right("0891 234", 4)) Val("1234") 1234
Thanks, your first option worked fine.
Cheers,
Phil

And Thanks for the both the Verbose AND the Condensed explanations!

I think for long time now, that the current implementation of CSS

The soon forthcoming CSS3 recommendation does not serve the public

what opacity is, how it is to applied to page elements.

We use an ISAPI filter to convert long urls into short clean ones.
For example:
"Site.com/user/john/"
Is re-written as:
"Site.com/user/userinfo.aspx?uid=john"
Now, "userinfo.aspx" contains a web user control which uses some Atlas functionality;
The web user control contains a "DataList" which gets updated asynchronously
through Atlas when the user clicks a button –the button is the Atlas trigger.

Go into a table where you have a field that has NULL values. Right-
Click on a record with a value in that field and choose "Filter
Excluding Selection". Some (or most, or all) of your records where
there is a NULL value in that field get eliminated.
Without getting crazy (i.e. designing your own bottons and "re-
inventing the wheel"), is there a way to make Access stop doing this?

Does anyone know how to do that? In my real project actually, I filter on two fields like this...
bindingsource.filter = "col1='" & var1 & "' AND col2='" & var2 & "'"
wherein var1 or var2 may contain a null value. Its just the same as if I want to show all records with null values.
Any ideas?

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
