Some of my queries stopped working after updating CCv6. After debugging them in phpmyadmin I found out that CC builds those queries wrong.
CC 6.0.7
Read data with a table t1 and a relation to a table t2.
t2 is set as "One matching record, foreign key in this table"
Foreign key is the field name of t2 related to a t1 field, not the primary key.
My t2.foreign key is not related to t1 primary key but to another t1 field. So I added a relation conditions:
T2.myforeignkey:T1.mykey
The query created was (probably wrong):
Select ... FROM T1
LEFT JOIN T2 on t1.mykey = T2.myforeignkey
As you can see the join between t1 primary key and t2 foreign key is missing. But the query worked for me.
CC 6.0.12
Read Data is the same as before but the query is different:
Select ... FROM T1
LEFT JOIN T2 on t1.primarykey = T2.myforeignkey
Now my additional relation is missing, and the (correct) join between primarykey and foreignkey is preventing the query from giving back any result.
My bad for using a bug to get a result but the latest version of CC is not right yet.
