Code sample

Node.js

To authenticate to Cloud SQL for SQL Server, set up Application Default Credentials. For more information, see Set up authentication for a local development environment.

try {
  const stmt =
    'INSERT INTO votes (time_cast, candidate) VALUES (@timestamp, @team)';
  // Using a prepared statement protects against SQL injection attacks.
  // When prepare is called, a single connection is acquired from the connection pool
  // and all subsequent executions are executed exclusively on this connection.
  const ps = new mssql.PreparedStatement(pool);
  ps.input('timestamp', mssql.DateTime);
  ps.input('team', mssql.VarChar(6));
  await ps.prepare(stmt);
  await ps.execute({
    timestamp: timestamp,
    team: team,
  });
  await ps.unprepare();
} catch (err) {
  // If something goes wrong, handle the error in this section. This might
  // involve retrying or adjusting parameters depending on the situation.
