Filtering two IBTable and insert or edit IBTable

[sx2008]

Zitat von mkinzler:

I would change the name when to a not reserved name.

WHEN is a reserved word.
Using reserved words in SQL could lead to VERY STRANGE errors.
I (and mkinzler) recommend to change the name of the field.

PS: don't set ParamType to ptUnknown! Set it to ptInput.
