# Proposed changes
`select k1 % 2.1 from test order by k1`
explain analyze plan:
PhysicalProject ( projects=[(k1 % 2.1)#14], stats=(rows=3, width=1,
penalty=0.0) )
+--PhysicalQuickSort ( orderKeys=[k1#1] )
+--PhysicalProject ( projects=[(cast(k1#1 as DECIMAL(4, 1)) % 2.1) AS
`(k1 % 2.1)`#14, k1#1], stats=(rows=3, width=1, penalty=0.0) )
+--PhysicalOlapScan ( qualified=default_cluster:test_query_db.test,
output=[k1#1,...], stats=(rows=3, width=1, penalty=0.0) )
when apply bind_project_function rule, we calculate data type for
binary_arithmetic `k1 % 2.1`. The binary_arithmetic datatype is the datatype of
its first child, that is tinyInt. This is wrong.
