DELETE
The examples below also work for the execute method.
query(sql)​
query(sql: string)
- promise.js
- callback.js
try {
const sql = 'DELETE FROM `users` WHERE `name` = "Page" LIMIT 1';
const [result, fields] = await connection.query(sql);
console.log(result);
console.log(fields);
} catch (err) {
console.log(err);
}
const sql = 'DELETE FROM `users` WHERE `name` = "Page" LIMIT 1';
connection.query(sql, (err, result, fields) => {
if (err instanceof Error) {
console.log(err);
return;
}
console.log(result);
console.log(fields);
});
- result: contains a ResultSetHeader object, which provides details about the operation executed by the server.
- fields contains extra meta data about the operation, if available
info
The connection used for the query (.query()) can be obtained through the createConnection, createPool or createPoolCluster methods.
query(options)​
query(options: QueryOptions)
- promise.js
- callback.js
try {
const sql = 'DELETE FROM `users` WHERE `name` = "Page" LIMIT 1';
const [result, fields] = await connection.query({
sql,
// ... other options
});
console.log(result);
console.log(fields);
} catch (err) {
console.log(err);
}
const sql = 'DELETE FROM `users` WHERE `name` = "Page" LIMIT 1';
connection.query(
{
sql,
// ... other options
},
(err, result, fields) => {
if (err instanceof Error) {
console.log(err);
return;
}
console.log(result);
console.log(fields);
}
);
