Idle connections not being closed by the pool

Based on the docs quick example, I am trying to run a simple query as follows:

const sql = require('mssql')

(async () => {
    try {
        const pool = await sql.connect('mssql://username:password@localhost/database')
        const result = await sql.query`select * from mytable where id = ${value}`
        console.dir(result)
    } catch (err) {
        // ... error checks
    }
})();

After logging the results, the process remains stucked until I press CTRL+C.

The problem is happening in the await sql.query part - it is returning a promise that seems to resolve, so I cannot figure out what is happening and why the process do not finish and keeps waiting for something.

Node 7.9.0 node-mssql 4.0.2

I have the same problem with the 4.10 version. I am using the connection pool when triggering a good amount of async queries. And after I return the results from the db, I explicitly close the connection pool but still the connections used remain active and the MSSQL server shows all the unclosed connection. For a heavy use, this makes the Db server to reach the max available connections and the Node.JS server can not connect anymore .

Is there any fix I can use?

Fixed in 4.0.4. Anyway, the fix doesn’t close the process when all connections are closed. You need to explicitly call pool.close().
