Self Join Condition fails in PHP but works in mysql

What the query builder makes out of your second where condition is:

WHERE parent.c_ID = 'child.c_ID'

So instead of a "normal" where() use whereRaw(), which takes your input and injects it right into the final SQL query

->whereRaw('parent.c_ID =

Alternatively you could also use DB::raw() on the third argument

->where('parent.c_ID', '=',

Both are essentially the same so use whichever you like more.

If condition in MySQL - can I use it like this?
No, you can't use IF like you show. You can only set a column to an expression, and the expression may contain an IF. The IF has an "else" argument, which may be the same column. If that happens, the column is assigned its own value, in which case no change will be made. And there must be only one SET keyword in an UPDATE. UPDATE kasutajad SET raadioslot0 = IF(raadioslot0 = %i, -1, raadioslot0),

[django+mysql]MySQLdb.connect works well, but cannot connect mysql via
The settings for the DB should be HOST and PORT, not DATABASE_HOST ... so try this: DATABASES = { 'default':{ 'ENGINE' : 'django.db.backends.mysql', 'NAME' : 'tasty', 'USER' : 'root', 'PASSWORD' : 'mycode', 'HOST' : '', 'PORT' : '3306', }, }
