Description
DROP TABLE IF EXISTS t1; |
CREATE TABLE t1 (a TINYINT) ENGINE=ColumnStore; |
INSERT INTO t1 VALUES (-1); |
SELECT LEFT('abc',a) FROM t1; |
+---------------+
|
| LEFT('abc',a) |
|
+---------------+
|
| abc |
|
+---------------+
|
Looks wrong. The expected result is:
DROP TABLE IF EXISTS t1; |
CREATE TABLE t1 (a TINYINT) ENGINE=InnoDB; |
INSERT INTO t1 VALUES (-1); |
SELECT LEFT('abc',a) FROM t1; |
+---------------+
|
| LEFT('abc',a) |
|
+---------------+
|
| |
|
+---------------+
|
The same problem is repeatable with functions:
DROP TABLE IF EXISTS t1; |
CREATE TABLE t1 (a TINYINT) ENGINE=ColumnStore; |
INSERT INTO t1 VALUES (-1); |
SELECT LEFT('abc',COALESCE(a,a)) FROM t1; |
+---------------------------+
|
| LEFT('abc',COALESCE(a,a)) |
|
+---------------------------+
|
| abc |
|
+---------------------------+
