Doctrine 2 - ORM

Impossibility to override built-in SQL functions

Details

  • Type: Bug Bug

    Any

Description

Doctrine doesn't allow to to create own SQL function for DQL if that function is already defined as "built-in". An example could be custom DATE_ADD implementation.
Method FunctionDeclaration() in Doctrine\ORM\Query\Parser gives higher priority to built-in SQL functions, even if they are not
usable for a specific situation, and registering of own datetime function doesn't help. This issue makes it impossible to use some advanced Doctrine extensions,
for example https://github.com/beberlei/DoctrineExtensions that provide fuller implementations.
Considering the fact that someone may want to use ready components provided by the community, and being new to Doctrine can't figure out the way to hack
or workaround this, the issue is a major one.

Just name the method differently.

To rename the method one has to KNOW that he has to rename it, i.e. to know about this issue.
One has to SPEND hours (like me) on understanding that there are built-in implementations and other extensions that are meant
to provide necessary features just don't work. IMHO it's just too cruel to leave it as is.

As to the renaming: is it ok to go and edit source code (change class name at least) provided by someone else and then merge all the sources when new releases appear?
Is that the only way flexible Doctrine provides? Also, I want DQL to be as close as possible to real SQL. I don't want to see weird stuff like MY_DATE_ADD or BETTER_DATE_ADD, or whatever it will be.
Syntax matters, we are all writers, code writers...

I re-open the issue in order to attract more attention, but you are free to decide how to treat it. Hope you'll find the best solution. A short line in documentation could notify about current limitations and save hours for people
who want to be productive with Doctrine.

Printing statements in bold isnt helpful. This is open-source.

However, you are right that this could be more user-friendly. Its now throwing an exception when an internal function is attempted to be overwritten.
