When i'm trying to pass missing values to a function called from a query like:
Expr1:my_functi on("fdf",,"fdf" ,,,,"fd")
I always obtain an error!
I'll try using:
Eval("my_functi on('fdf',,'df', ,,,'fd')")
to see what happens!
Any other suggestions?
TIA

What's the VBA of your function Vladi?
And can you post some SQL examples of trying to use it.

'Make sure that the number of Arguments passed to the Function matches the
'number of declared Parameters contained within the Function, both number

Unless the missing parameters are set as optional in the function it won't work.

Sure
I've tried a lot but no chance! Finnally i've done the function to accept both:
Null
and missing values and the problem is resolved!
Eval didn't work in this case!
If it worked can do a great job coz i'm using this function to send mails, and when the body is html u can guess what happens with " and ' :)
Simply in the function i've introduced the null to be acceptable value and it is Ok now!
Thanks for your suggestions!

The arguments are on the correct place but are optional! This is all of the problem obviously!
It's pitty that in the query you should use null for optional arguments, but sometimes it gives errors in some functions!
For my functions with optional parameters i'll include the nulls also like a source of missing parameter!
:)
I'll come back soon in the forum people!

Vladi,
Optional arguments does NOT mean using a Null!
If you pass a field to a function that is passing an argument - it is simply a Null argument.
In the code, the functions IsNull() & IsMissing() are two different things.
If you pass a Null to an optional string parameter, for instance, that will give an error.

I've read about this error in several other discussions, but still
can't seem to pinpoint the problem with my code. Everything seemed to
be working fine for some time, but it now tends to bomb out on me for
some reason. The Summary field is pulled from a Rich Text Editor that
allows HTML formatting and appears to be the culprit, but I just can't
seem to figure out why. Any guidance is greatly appreciated.

Hello folks,
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.
This is as boiled down as I can make it.
Here is my compilation command:
