feiwang updated SPARK-30471:
----------------------------
Description:
When we comparing a String Type and IntegerType:
'2147483648'(StringType, which exceed Int.MaxValue) > 0(IntegerType).
Now the result of findCommonTypeForBinaryComparison(StringType, IntegerType) is
IntegerType.
But the value of string may exceed Int.MaxValue, then the result is corruputed.
For example:
{code:java}
// Some comments here
CREATE TEMPORARY VIEW ta AS SELECT * FROM VALUES(CAST ('2147483648' AS
STRING)) AS ta(id);
SELECT * FROM ta WHERE id > 0;
{code}
> Fix issue when compare string and IntegerType
