## commonjs usage
`npm install --save js-sql-parser`
```js
const parser = require('js-sql-parser');
const ast = parser.parse('select * from dual');
console.log(JSON.stringify(ast, null, 2));
ast.value.selectItems.value[0].value = 'foo';
ast.value.from.value[0].value.value.value = 'bar';
console.log(parser.stringify(ast));
// SELECT foo FROM bar
```
```js
// placeholder test
const parser = require('js-sql-parser');
const ast = parser.parse('select ${a} as a');
ast['value']['selectItems']['value'][0]['value'] = "'value'";
console.log(parser.stringify(ast));
// SELECT 'value' AS a
```
Note: PlaceHolder is an `literal` value but not an `identifier`. Table_name / column_name / function_name are `identifier` thus should NOT be placed with placeholder.
## script tag
```js
<script/>
var sqlParser = window.sqlParser;
var ast = sqlParser.parse('select * from dual');
var sql = sqlParser.stringify(ast);
```
