Hi Alex,
1. Does the description mean that criteria is always the same size of tablecolumns?
Although one could argue that it would be legal that criteria could be smaller than the number of columns, I think it is a safer choice to make them always the same size.
2. If so, does that mean, that criteria={"m�ller","alex", null}; results in all records?
Again, this is a choice one can make: AND-type or OR-type searching. I choose for AND-type searching, because it seemed to have more practical use. In that case the criteria would select all records where the first field starts with "m�ller" and the second starts with "alex". The criteria (null,null,null) would always select all records.
3. What do i do with an empty string? I want to use regexpression and an empty string matches any string. But this makes no sence, isn't it?
According to the interface definition, an empty string indeed matches any string (because any string starts with an empty string). So an empty string does the same as a null string.
Frans.
