示例1: test_promise_returns
function test_promise_returns() {
// Methods return a promises if the callback is omitted.
var connection: sql.ConnectionPool = new sql.ConnectionPool(config);
connection.connect().then(() => { });
connection.close().then(() => { });
var preparedStatment = new sql.PreparedStatement(connection);
preparedStatment.prepare("SELECT @myValue").then(() => { });
preparedStatment.execute({ myValue: 1 }).then((recordSet) => { });
preparedStatment.unprepare().then(() => { });
var transaction = new sql.Transaction(connection);
transaction.begin().then(() => { });
transaction.commit().then(() => { });
transaction.rollback().then(() => { });
var request = new sql.Request();
request.batch('create procedure #temporary as select * from table').then((recordset) => { });
request.batch<Entity>('create procedure #temporary as select * from table;select 1 as value').then((recordset) => { });
request.bulk(new sql.Table("table_name")).then(() => { });
request.query('SELECT 1').then((recordset) => { });
request.query`SELECT ${1} as value`.then(res => { });
request.query<Entity>('SELECT 1 as value').then(res => { });
request.execute('procedure_name').then((recordset) => { });
