Comment (by r4ge):
Hi, I may be wrong as this I am just new to this.
The issue seems to be here "/backends/oracle/operations.py"
{{{
def lookup_cast(self, lookup_type, internal_type=None):
if lookup_type in ("iexact", "icontains", "istartswith",
"iendswith"):
return "UPPER(%s)"
if internal_type == "JSONField" and lookup_type == "exact":
return "DBMS_LOB.SUBSTR(%s)"
return "%s"
}}}
The condition might be
{{{
if internal_type != "JSONField" and lookup_type == "exact": # if the type
is not JSONField
}}}
Can I pick this up?
