Can't catch prepared statement failure

const ps = new sql.PreparedStatement()
ps.input('param', sql.Int)
ps.prepare('select non-exisiting-column from table_name where phone = @phone')
.then(() => {
    // fails with uncaughtException, never happens
}).catch(er => console.error(e)) // never happens

Fails with uncaughtException Tried with plain promises and async/await

[Error: [Microsoft][SQL Server Native Client 11.0][SQL Server]Statement(s) could not be prepared.] {

My conclusion is that msnodesqlv8 is emitting multiple error events under this scenario, this is a very difficult situation to handle as really we’d expect a connection to have a 1-1 query to error output. If a connection can output many errors then we don’t know when we can expect the errors to stop coming and when the connection can be safely released back to the pool.

I’m going to open an issue with the driver and see if I can get any advice. see https://github.com/TimelordUK/node-sqlserver-v8/issues/133
