So now in my config instead of using host: 'localhost\\SQLEXPRESS' I'm using host: 'localhost'

Thanks. Will check on that too. Right now I've upped my pool.max to 10000 and running some tests.

question, by default querying date columns inflates them to JavaScript Date objects. I can’t figure out, without doing a post-query map, how to get those as strings. Is there a way to specify that I want certain column types always back as a string?

Jason Luboff

@JLuboff

@jbw91 In your select statement use a Cast or Convert

John Woodruff

@johnbwoodruff

in my situation that’s not ideal, as it’s generated queries based on various criteria, and I won’t know when it’s a date column vs not to be able to cast it.

I was hoping there’d be some built in option, like is found in the pg package.

it essentially allows me to provide a parseFn for specified data types

Jason Luboff

@JLuboff

Gotcha. I've never dealt with generated queries, so can't be of much help unfortunately.

John Woodruff

@johnbwoodruff

thanks for trying! :)

Hi, im having an issue:
Im trying to install and try some code with mssql, but whenever I try to run the code it gives me: "Unknown plugin "transform-runtime""
Any suggestions?

Hi all, My query looks like

select 1,2,3,4;

in results.recordset, what i was exptecting is for the object result.recordset.toTable()

{
    "columns":[
        {"name":"","nullable":false},
        {"name":"","nullable":false},
        {"name":"","nullable":false},
        {"name":"","nullable":false}
    ],"
    rows":[
        [1,2,3,4]
    ]
}

instead I am getting

{"columns":[{"name":"","nullable":false}],"rows":[[[1,2,3,4]]]}

How to overcome this? (Results are automatically grouped in to object based on column headers. in my case no column names are preset. )

@nelsonwellswku

does anyone have any experience using transactions with promises or async await? i'm calling trans.rollback() but it doesn't seem to actually perform the rollback and I'm at a loss why

Nelson Wells

@nelsonwellswku

I figured it out. You can't use connection.request(transaction) if your transaction was made with a different connection. derp.

Greetings, wondering if anyone has had experiences with using bulk requests and inserting geometry type data? I have a pretty simple scenario but specifically introduction a geometry column results in this error

Hey everyone, I was wondering, is it possible to change the database being connected to in a connection pool?

I mean after using it once. Or should I create new pools for each DB I'm connecting to?

David Gasperoni

@mcdado

FWIW I do create new pools. Couldn’t manage to change db.

Chris Rutherford

@cjrutherford

it's okay, I just didn't specify a database, and used unambiguous table names to get the right DB. i.e: select * from [database].[dbo].[tableName]

Hi all. I'm trying to figure out how to receive the 'row' event from a query run against a Request object. The code looks like this:

this[data] = await new Promise((resolve, reject) => {
    var request = new sql.Request(this[db]);
    var query = queries.getErrors;

    //get the records for the block #blockNo
    request.on('row', (row) => {
        console.log(`Got row!`);
    });
    request.query(query, (err, result) => {
        if (err) {
            console.error(`An error occurred while processing the request: \n${err}`);
            reject(err);
        }
        else {
            console.info(`Received ${result.recordset.length} records.`);
            resolve(result.recordset);
        }
    });
}) || [];

Problem is that even though I get 500+ records back, the row event never fires. Any suggestions?

Hey! Does anyone knwo how to simply open a connection async, make a request async and close eonnction

I don't want to deal with calbacks

David Gasperoni

@mcdado

@teb951999 if you want to do async you either use callbacks or promises

I’m afraid

Maybe await / async by you need a recent version of Node, and personally I never used it

I'm trying to pull in data from five different databases, and it looks like everything is coming through, but I can't continue because of this trace stack... I'm not sure where the unhandled promise rejection is located. Is it in my code? here's the call stack:

@JLuboff

@cjrutherford Do you have this bit Symbol(Symbol.iterator) some where in your code? Or in a query?

Chris Rutherford

@cjrutherford

Sorry I found out it was because I was using Promise.all() with an object instead of an array..... sorry

Jason Luboff

@JLuboff

All good, I may not have even had the answer but still try to help :smile:

hi every one

can any one tell me how to do transcations in node js for mssql?

to write transactional queries in node for mssql queries?/

help me

David Gasperoni

@mcdado

I think you just write them in the SQL queries? You just need to make sure you use the same connection for transaction

Sorry I yet never written a transaction

Jason Luboff

@JLuboff

@vijaylakkavaram The docs explain how to use a transaction https://www.npmjs.com/package/mssql#transaction

If you need to set an isolation level, you just do

transaction.begin('SERIALIZABLE').then(() => { ...

Hi there all, trying to connect to an old SQL server 2000 instance, and I'm using SQL.connect() work a template strong building the connection string how can I add in the TDS version to that? Or how would I convert to a config object?

NVM. Got it. Just moved away from the template string

andrew bernard

Jason Luboff

@JLuboff

@drexler Are you using SQL Express?

andrew bernard

@drexler
