Function find_identifier_span 

pub fn find_identifier_span(
    sql: &str,
    identifier: &str,
    search_start: usize,
) -> Option<Span>

Finds the byte offset span of an identifier in SQL text.

Searches for the identifier as a whole word (not part of another identifier). Returns the first match found, or None if not found.

Arguments

• sql - The SQL source text
• identifier - The identifier to find (table name, column name, etc.)
• search_start - Byte offset to start searching from (for multi-statement SQL)

Example

let sql = "SELECT * FROM users WHERE id = 1";
let span = find_identifier_span(sql, "users", 0);
assert_eq!(span, Some(Span { start: 14, end: 19 }));
