Hi, This query works fine: create table t1 (d date) PARTITION BY RANGE (d); CREATE TABLE t1_p1 PARTITION OF t1 FOR VALUES FROM ('2000-01-01') TO ('2019-01-01'); Same query, but now (using domain): CREATE DOMAIN ddate AS date; create table t1 (d ddate) PARTITION BY RANGE (d); CREATE TABLE t1_p1 PARTITION OF t1 FOR VALUES FROM ('2000-01-01') TO ('2019-01-01'); The follow error occur: SQL Error [42804]: ERROR: specified value cannot be cast to type ddate for column "d" Detalhe: The cast requires a non-immutable conversion. Dica: Try putting the literal value in single quotes. Posição: 55 I cannot use domain in this case? Thanks in advance! -- Att Márcio |
