Join Involving View and ATAN2 function produce wrong result

[TheoristCoder]

Bug Report

1. Minimal reproduce step (Required)

CREATE TABLE t0(c0 int);

CREATE TABLE t1(c0 DECIMAL);

INSERT INTO t1(c0) VALUES (1687);
INSERT  INTO t0(c0) VALUES (0);


CREATE VIEW v0(c0) AS SELECT CAST(((t1.c0)DIV(t1.c0)) AS DECIMAL) FROM t1;


SELECT * FROM v0 INNER JOIN t0 ON ( (v0.c0 LIKE CAST(v0.c0 AS CHAR) ) <= (((t0.c0))) AND ((NOT (ATAN2(t0.c0, v0.c0)))) );

2. What did you expect to see? (Required)

Empty result

3. What did you see instead (Required)

1.000000000000000000000000000000 , 0

More importantly, if I just create a identical table instead of using view:

CREATE TABLE t0(c0 int);
INSERT  INTO t0(c0) VALUES (0);

CREATE TABLE v0(c0 DECIMAL);
INSERT INTO v0(c0) VALUES (1.00000);

SELECT * FROM v0 INNER JOIN t0 ON ( (v0.c0 LIKE CAST(v0.c0 AS CHAR) ) <= (((t0.c0))) AND ((NOT (ATAN2(t0.c0, v0.c0)))) );

It will produce correct result which is same as that of mysql.

4. What is your TiDB version? (Required)
