Macro write_sql 

write_sql!() { /* proc-macro */ }

A procedural macro for writing SQL strings with automatic ToSql formatting.

This macro parses format strings at compile time and generates code that calls ToSql::fmt_sql for each placeholder argument.

Syntax

write_sql!(f, fmt, "format string", arg1, arg2, ...)

Where:

• f is a mutable reference to a String
• fmt is a SqlFormat value
• "format string" contains literal text and placeholders
• Arguments follow for each positional placeholder

Placeholders

• {} - Positional placeholder (uses corresponding argument from the list)
• {identifier} - Named placeholder (uses variable with that name in scope)

Examples

use surrealdb_types::{write_sql, SqlFormat, ToSql};

let mut f = String::new();
let fmt = SqlFormat::SingleLine;

// Positional placeholders
write_sql!(f, fmt, "{}", value);
write_sql!(f, fmt, "a: {}, {}", b, c);

// Named placeholders
let x = 42;
write_sql!(f, fmt, "x = {x}");

// Mixed
write_sql!(f, fmt, "{a} {} {c}", b);
