Macro fx 

macro_rules! fx {
    ($name:expr, $($arg:expr),+ $(,)?) => { ... };
}

Macro for building SQL function calls with automatic .expr() on arguments.

Each argument has .expr() called via the Expressive trait, so you can pass Identifier, Column, Fx, scalars, or any Expressive<T> directly.

Examples

use vantage_sql::primitives::*;

// Single argument
fx!("count", sqlite_expr!("*"))

// Multiple arguments
fx!("coalesce", ident("name"), "unnamed")

// Nested function calls
fx!("round", fx!("avg", ident("price")), 2i64)
