  19. def resolve(expression: Expression): Expression

    Resolves type coercion for expression by applying necessary transformations on the expression and its children.

    Resolves type coercion for expression by applying necessary transformations on the expression and its children. Because fixed-point sometimes resolves type coercion in multiple passes, we apply each provided transformation twice, cyclically, to ensure that types are resolved. For example in a query like:

    SELECT '1' + '1'

    fixed-point analyzer requires two passes to resolve types.
