Initial merge done with d32e203 (r10792). Assefa needs to merge his WXS modifications and I still have the following tasks:

• context expressions (e.g. requires/labelrequires)
• raster expressions
• GEOMTRANSFORM writing

FYI... ba41ac8 (r10793) contains a couple of file changes I missed with d32e203 (r10792).

Nuts, I forgot to merge the query changes (new method) with that original batch. 70e32f0 (r10827) and 2d3356f (r10828) contain those changes. Basically this adds msQueryByFilter() to mapquery.c and exposes it (mostly for testing) via SWIG MapScript as queryByFilter for map and layer objects.

Steve,

what operators should I use for case insensitve filter requests for Equal and isLike?
I use now == for PropertyIsEqualTo and ~* for PropertyIsLike

Thx

For use =* for is PropertyIsEqualTo and ~* PropertyIsLike. The * signals the case-insensitive comparison. Note the ~ is a regex operator... Make sense?

Steve I am not I understand since my tests do not work for PropertyIsLike case sensitive

PropertyIsEqualTo works as expected with the following settings:

"[Attribue]" =* "value"  /*for case insenstive*/
"[Attribue]" == "value"  /*for case senstive*/

For PropertyIsLike I tried to set the filters like this

"[Attribue]" ~* "value-regex"  /*for case insensitive*/: works
"[Attribue]" =~ "value-regex"  /*for case sensitive*/ : does not work

Note that the by "value-regex", I mean that things like wild card '*', ... are included in it.
What is the operator I need to use for case sensitive?

Use =, ~ to do case sensitive (== works but is deprecated in my mind). Use =_, ~_ to do case insensitive.

I have been doing some updates to the expression document, and also to related documents (in MapServer/MapServer-documentation@d6a1293 (r11858), MapServer/MapServer-documentation@4e5fd3e (r11889), MapServer/MapServer-documentation@747bfd3 (r11895), MapServer/MapServer-documentation@f33eba3 (r11973), MapServer/MapServer-documentation@e56830e (r11974)). It would be good if Steve could have a look and say what remains to be done before we can close this ticket.

@sdlime , could you check if the documentation is OK, and then close the issue or provide instructions.

Closing. Any new issues would have manifested themselves in specific tickets.
