Nesting functions in 'where' in 4.3

Path Finder

Hi,

Very quick question that someone may be able to answer.

In a complex form search that we have, we use the 'where' function to filter the results. So that the data is case-insensitive, we use the 'lower' function.

In version 4.2.5, this syntax works fine:

where like(lower(Room),lower("%MB.1%"))

('Room' is a field in the search, the other data is user entered so can vary wildly)

In version 4.3, I get the error:

"Error in 'where' command: The arguments to the 'like' function are invalid."

Is this an error, or can we no longer nest functions?

Any advice or suggestions would be appreciated.

Thanks,

Graham.

It works in v6 but why are you lowering your match string; why not just lower it yourself like this:

where like(lower(Room),"%mb.1%"))

Assuming that there actually is some valid reason for needing this (e.g. you are using a $token$ for the match string), switch from SQL-type like to RegEx-type match and use the ignorecase inline token like this:

where match(lower(Room),"(?i)MB.1"))

Hi. Wow, this takes me back a few years...

Thanks for your answer.

Yes, the question did relate to the use of a $token$ in an Advanced XML View. Otherwise yes, I get that I could turn off Cap Lock and type the string in lowercase(!)

But thank you for the suggestion of using the match function. I hadn't come across it before and I think it will prove useful in a number of different situations.

I am mining older unanswered questions for karma so please accept my answer. I am glad it was at least educational, if it could not be useful.
