Description
Bug Description
An error occurred during binary arithmetic operations between the time field and the data field.
To Reproduce
Assume that we execute the following statement under a database named testdb.
DROP TABLE t1;
CREATE TABLE t1( time TIMESTAMP, c0 INT);
INSERT INTO t1(time, c0) VALUES (1641024000000, 1);
# query 1 success
SELECT time, c0 FROM t1 WHERE (time - c0) > 0;
SELECT time, c0 FROM t1 WHERE (time + c0) > 0;
SELECT time, c0 FROM t1 WHERE (-(-c0)) > 0;
# query 2 error
SELECT time, c0 FROM t1 WHERE (time - (-c0)) > 0;
Expected Behavior
The query statement 1 and query statement 2 can both retrieve all the data.
Actual behaviour
Query 1 can retrieve all the data, but Query 2 returns an error: DB error: Invalid operation.
Environment
- OS:Ubuntu Server 22.04 LTS 64bit
- TDengine Version:3.3.3.0
Additional Context
Hello, TDengine team. I'd like to confirm with you whether this is a bug? Because Query 1 and Query 2 are equivalent.
