Description

DROP TABLE IF EXISTS t1;

CREATE TABLE t1 (a VARCHAR(2) NOT NULL DEFAULT 'aa') ENGINE=ColumnStore;

INSERT INTO t1 VALUES ('');

SELECT HEX(a) FROM t1;

+--------+

| HEX(a) |

+--------+

| 6161   |

+--------+

Notice, emptry string was conversion to default 'aa'. Looks wrong.

DROP TABLE IF EXISTS t1;

CREATE TABLE t1 (a VARCHAR(2) NOT NULL DEFAULT ' ') ENGINE=ColumnStore;

INSERT INTO t1 VALUES ('');

SELECT HEX(a) FROM t1;

+--------+

| HEX(a) |

+--------+

| 20     |

+--------+

Notice, emptry string was conversion to default ' '. Looks wrong.

DROP TABLE IF EXISTS t1;

CREATE TABLE t1 (a VARCHAR(2) NOT NULL DEFAULT '  ') ENGINE=ColumnStore;

INSERT INTO t1 VALUES ('  ');

SELECT HEX(a) FROM t1;

+--------+

| HEX(a) |

+--------+

| 2020   |

+--------+

Notice, emptry string was conversion to default ' '. Looks wrong.

In all above scenarios, INSERTs should:

either fail on NOT NULL violation for now
or insert an empty string (when we fix the flaw that emptry string is NULL)

But it should not replace to DEFAULT!
