--source include/have_partition.inc

CREATE TABLE t (a INT, b TEXT, UNIQUE (b)) PARTITION BY LIST (a) (PARTITION p0 VALUES IN (1,2), PARTITION pdef DEFAULT);

CREATE TABLE tp (a INT, b TEXT, UNIQUE (b));

ALTER TABLE t EXCHANGE PARTITION p0 WITH TABLE tp;

# Cleanup

DROP TABLE t, tp;

CREATE TABLE t (a INT, b TEXT, UNIQUE (b)) PARTITION BY LIST (a) (PARTITION p0 VALUES IN (1,2), PARTITION pdef DEFAULT);

CREATE TABLE tp (a INT, b TEXT, UNIQUE (b));

ALTER TABLE t EXCHANGE PARTITION p0 WITH TABLE tp;
