我们刚刚发布了用于 SQL Server 连接的 Node.JS 预览驱动程序。您可以在此处找到它:
Introducing the Microsoft Driver for Node.JS for SQL Server。
驱动程序支持回调(这里,我们连接到本地 SQL Server 实例):
// Query with explicit connection
var sql = require('node-sqlserver');
var conn_str = "Driver={SQL Server Native Client 11.0};Server=(local);Database=AdventureWorks2012;Trusted_Connection={Yes}";
sql.open(conn_str, function (err, conn) {
if (err) {
console.log("Error opening the connection!");
return;
}
conn.queryRaw("SELECT TOP 10 FirstName, LastName FROM Person.Person", function (err, results) {
if (err) {
console.log("Error running query!");
return;
}
for (var i = 0; i < results.rows.length; i++) {
console.log("FirstName: " + results.rows[i][0] + " LastName: " + results.rows[i][1]);
}
});
});
或者,您可以使用事件(这里,我们连接到 SQL Azure aka Windows Azure SQL 数据库):
// Query with streaming
var sql = require('node-sqlserver');
var conn_str = "Driver={SQL Server Native Client 11.0};Server={tcp:servername.database.windows.net,1433};UID={username};PWD={Password1};Encrypt={Yes};Database={databasename}";
var stmt = sql.query(conn_str, "SELECT FirstName, LastName FROM Person.Person ORDER BY LastName OFFSET 0 ROWS FETCH NEXT 10 ROWS ONLY");
stmt.on('meta', function (meta) { console.log("We've received the metadata"); });
stmt.on('row', function (idx) { console.log("We've started receiving a row"); });
stmt.on('column', function (idx, data, more) { console.log(idx + ":" + data);});
stmt.on('done', function () { console.log("All done!"); });
stmt.on('error', function (err) { console.log("We had an error :-( " + err); });
