[GitHub] [incubator-doris] xinyiZzz opened a new issue #7349: [Bug] Rewrite Bigint SlotRef to compare DecimalLiteral in Binary predicate
xinyiZzz opened a new issue #7349:
URL: https://github.com/apache/incubator-doris/issues/7349
### Search before asking
- [X] I had searched in the [issues](https://github.com/apache/incubator-doris/issues?q=is%3Aissue) and found no similar issues.
### Version
trunk
### What's Wrong?
For query "select * from T where t1 = 2.0", when the ResultType of column t1 is equal to BIGINT, in the binary predicate analyze, the type will be unified to DECIMALV2, so the binary predicate will be converted to <CastExpr<SlotRef>> <op In the form of ><DecimalLiteral>, because Cast wraps the t1 column, it cannot be pushed down, resulting in poor performance.
### What You Expected?
Convert it to the equivalent query "select * from T where t1 = 2" to push down and improve performance.
### How to Reproduce?
_No response_
### Anything Else?
