I am doing the request, it writes an error
id – INTEGER PRIMARY KEY
help
cur = db.query("Sales_region_table t1, region_table t2 join region_table t2 on t1.id_region = t2.id ", null, " id_region = " + id_region + " and id_category = " + id_category + " and id_product = " + id_product + " ", null, null, null, null);
11-01 08:28:10.600: I/Database(1251): sqlite returned: error code = 1, msg = ambiguous column name: t2.id
The issue is around:
You’re selecting from
region_table t2and joining to the same table (with the same alias name).This causes ambiguity on the RDBMS.
