Typeless Rules

A typeless expression is a concatenation or sum of elements whose type (between String, Numeric, and Date) cannot be distinguished without context. <Typeless Exp> consists of one of these:

<Typeless Exp> + <Typeless Value>

<Typeless Value>

A typeless value can be any of these:

• A variable reference
• A function call whose type cannot be determined without context
• A typeless sub-expression enclosed in parentheses

<Typeless Value> consists of one of these:

<IdValue>

IF (<Boolean Exp>, <Typeless Exp>, <Typeless Exp>)

DBFUNCTION (<Parameter List>)
