MySQL Formatter

module.exports = function(client) { var Formatter = require('../../formatter'); var inherits = require('inherits');

The "formatter" is used to ensure all output is properly escaped & parameterized.

function Formatter_MySQL() { this.client = client; Formatter.apply(this, arguments); } inherits(Formatter_MySQL, Formatter); Formatter_MySQL.prototype.operators = [ '=', '<', '>', '<=', '>=', '<>', '!=', 'like', 'not like', 'between', 'ilike', '&', '|', '^', '<<', '>>', 'rlike', 'regexp', 'not regexp' ];

Wraps a value (column, tableName) with the correct ticks.

Formatter_MySQL.prototype.wrapValue = function(value) { return (value !== '*' ? '`' + value + '`' : '*'); };

Memoize the calls to "wrap" for a little extra perf.

var wrapperMemo = (function(){ var memo = Object.create(null); return function(key) { if (memo.key === void 0) { memo[key] = this._wrapString(key); } return memo[key]; }; }()); Formatter_MySQL.prototype._wrap = wrapperMemo;

Assign the formatter to the the client.

client.Formatter = Formatter_MySQL; };
