Description:
When the slave has more columns/fields than the master and such fields do not accept null
or do not have a default value, it must fail if in strict mode. Otherwise, it should
succeed and the extra fields should be populated with automatic values. If there is a
default value, it should be used by default. However, this is not happening.
CURRENT RESULTS:
----------------
1 - FIRST CASE (NOT NULL / NO DEFAULT VALUE)
master:
CREATE TABLE t1(`a` INT, `b` INT) ENGINE=NDB;
slave:
CREATE TABLE t1(`a` INT NOT NULL, `b` INT NOT NULL,
`c` INT NOT NULL) ENGINE=NDB;
INSERT INTO t1(a) VALUES (1); produces the following result:
master
SELECT * FROM t1 ORDER BY a;
a b
1 NULL
SELECT * FROM t1 ORDER BY a;
a b c
2 - SECOND CASE (NOT NULL / DEFAULT VALUE)
master:
CREATE TABLE t2(`a` INT, `b` INT) ENGINE=NDB;
slave:
CREATE TABLE t2(`a` INT NOT NULL, `b` INT NOT NULL,
`c` INT NOT NULL DEFAULT 500) ENGINE=NDB;
INSERT INTO t2(a) VALUES (1); produces the following result:
master
SELECT * FROM t2 ORDER BY a;
a b
1 NULL
SELECT * FROM t2 ORDER BY a;
a b c
3 - SECOND CASE (NULL / DEFAULT VALUE)
master:
CREATE TABLE t3(`a` INT, `b` INT) ENGINE=NDB;
slave:
CREATE TABLE t3(`a` INT NOT NULL, `b` INT NOT NULL,
`c` INT DEFAULT 500) ENGINE=NDB;
INSERT INTO t3(a) VALUES (1); produces the following result:
master
SELECT * FROM t3 ORDER BY a;
a b
1 NULL
SELECT * FROM t3 ORDER BY a;
a b c
1 0 NULL
4 - SECOND CASE (NULL / NO DEFAULT VALUE) (OK)
master:
CREATE TABLE t4(`a` INT, `b` INT) ENGINE=NDB;
slave:
CREATE TABLE t4(`a` INT NOT NULL, `b` INT NOT NULL,
`c` INT) ENGINE=NDB;
INSERT INTO t4(a) VALUES (1); produces the following result:
master
SELECT * FROM t3 ORDER BY a;
a b
1 NULL
SELECT * FROM t4 ORDER BY a;
a b c
1 0 NULL
CORRECT RESULTS:
----------------
1 - FIRST CASE (NOT NULL / NO DEFAULT VALUE)
master:
SELECT * FROM t1 ORDER BY a;
a b
1 NULL
slave:
SELECT * FROM t1 ORDER BY a;
a b c
1 0 0
2 - FIRST CASE (NOT NULL / DEFAULT VALUE)
master:
SELECT * FROM t2 ORDER BY a;
a b
1 NULL
slave:
SELECT * FROM t2 ORDER BY a;
a b c
1 0 500
3 - FIRST CASE (NULL / DEFAULT VALUE)
master:
SELECT * FROM t3 ORDER BY a;
a b
1 NULL
slave:
SELECT * FROM t3 ORDER BY a;
a b c
1 0 500
4 - FIRST CASE (NULL / NO DEFAULT VALUE)
master:
SELECT * FROM t4 ORDER BY a;
a b
1 NULL
slave:
SELECT * FROM t4 ORDER BY a;
a b c
1 0 NULL
