Usage
Mapping SQL Column Names
You can use the sqlNameToColumn
function to map SQL column names to new names using a provided map. Here is an example:
import { sqlNameToColumn } from '@toshihiko/sql-utils';
const sql = 'SELECT aa FROM b WHERE cc = dd';
const map = {
aa: 'a',
cc: 'c',
dd: 'd',
};
const newSql = sqlNameToColumn(sql, map);
console.log(newSql); // Output: SELECT a FROM b WHERE c = d
Escaping SQL Strings
Use the escape
function to escape special characters in a string to prevent SQL injection:
import { escape } from '@toshihiko/sql-utils';
const userInput = 'It\'s a "quoted" string';
const escapedString = escape(userInput);
console.log(escapedString); // Output: It\'s a \"quoted\" string
Escaping Strings for SQL LIKE Clauses
Use the escapeLike
function to escape special wildcard characters used in SQL LIKE clauses:
import { escapeLike } from '@toshihiko/sql-utils';
const searchTerm = '50%_discount';
const escapedTerm = escapeLike(searchTerm);
console.log(escapedTerm); // Output: 50\%\_discount
