npm 上的 node-mysql 文档(https://npmjs.org/package/mysql)有一个选项用于在表连接中重叠列名,如下所示:
var options = {sql: '...', nestTables: true};
connection.query(options, function(err, results) {
/* results will be an array like this now:
[{
table1: {
fieldA: '...',
fieldB: '...',
},
table2: {
fieldA: '...',
fieldB: '...',
},
}, ...]
*/
});
转义查询标识符格式将第二个参数传递给connection.query()
清理标识符的参数:
connection.query('SELECT * FROM users WHERE id = ?', [userId], function(err, results) {
// ...
});
我想知道你如何将这两个一起使用?假设您需要在连接中转义标识符,但想要声明嵌套表的选项:
var sqlString: 'SELECT * FROM TableOne INNER JOIN TableTwo ON TableOne.id = TableTwo.tableone_id WHERE TableOne.id = ?';
var options = {sql: sqlString, nestTables: true};
connection.query(options, function(err, results) {
...
});
我试图将转义值作为第二个参数传递,connection.query()
如下所示:
var sqlString: 'SELECT * FROM TableOne INNER JOIN TableTwo ON TableOne.id = TableTwo.tableone_id WHERE TableOne.id = ?';
var options = {sql: sqlString, nestTables: true};
connection.query(options, 1, function(err, results) {
...
});
但无济于事。我想知道是否有办法做到这一点?
