# Proposed changes
For an vectorized expression which meets the condition
`vexpr->is_constant()`, a const column is expected to return.
But now we still don't cover all predicates for const expression.
For example, for query `SELECT col FROM tbl WHERE 'PROMOTION' LIKE 'AAA%'`,
predicate `like` will return a ColumnVector<UInt8> which contains a single
value.
This PR want to cover all const predicates whether it returns a constcolumn
or not
