Alright, I was just wondering. Because that definitely adds some delay. I’m not sure about blocking though, as you seem to always do the right thing and return promises/callbacks

hi im trying to dynamically add tvp data into tvp table. I need some help here…
I have already new the table and added the columns no problem there

let columns = _.map(tvpData.columns, 'name');
tvpData.data.forEach((item) => {
        tvp.rows.add.apply(null, columns.map((c) => item[c]));
});

but it seems stuck in this foreach. any help would be appreciated

Looking into tools to test against a DB and someone pointed me here. I need to test against SQL Management studio client I guess it's a GUI interface but should still be able to throw commands at it. Would this library work to verify that a job is set correctly and ran?

Tim Oien

@toien44

What tools do people use for using this on a mac? I need a GUI interface too to verify my tests/ steps.

I used to use MySQL Workbench. Don't know if it is compatible with MSSQL. Failing that you can always install Windows on a VirtualBox VM

If you’re looking to issue SQL commands against a SQL DB on a Mac, I recommend using VS Code. It works well, includes intellisense and source control. Plus it’s good for just about any other language you need to develop in.

Tim Oien

@toien44

ok thanks all

dmanhaus

@dmanhaus

...just be sure to add the MSSQL extension after you install it.

Tim Oien

@toien44

I'm not looking for an editor as I have one I need a way to view the tables on a mac. I'd prefer to not use a VM

Sean Kelly

@seank-com

VSCode will display a table as a result of your SQL query. It's really pretty slick.

Tim Oien

@toien44

oh nice thanks

Sql operations Studio by Microsoft

It’s in alpha I think

It’s an electron-based app that’s multi-platform

I'm trying to set up a DB connection would host be the name of the database or a URL?

var mysql      = require('mysql');
var connection = mysql.createConnection({
  host     : 'localhost',
  user     : 'me',
  password : 'secret',
  database : 'my_db'
});

connection.connect((err) => {
    if (err) {
        console.error(`error connecting: ${err.stack}`);

        return;
    }

    console.log(`connected as id ${connection.threadId}`);
});

connection.end();

@toien44

I got the HOST figured out however, I can't get the console log to print out

Hi folks,

Does anyone have any experience with using SESSION_CONTEXT on SqlServer 2016/2017?

I'm running into some issues, and I'm hoping someone can help me confirm it's not just me!

// Assuming some connection pool: cp
const sql = require('mssq');
const request = new sql.Request(cp).query("SELECT SESSION_CONTEXT(N'user_var') AS [sc]");
request
    .then(r => console.log(r))
    .catch(e => console.log(e));

I'm running into an internal error, with an unknown sqlstate. I'm hoping I'm missing something here. Any ideas?

Cheers!

Oliver Jourmel

@ojourmel

Turns out this error is caused by invalid types... SESSION_CONTEXT returns sql_variant which is not supported by node-mssql.

Casting / converting the result to nvarchar seems to fix the error:

SELECT CONVERT(NVARCHAR(max), SESSION_CONTEXT(N'key')) AS [sc]

Cheers!

Hi, I'm new using mssql module and I'm trying to implement a repository where each method open a execute some queries and then close the pool but when I stress the method I'm receiving an error about global connection that already exists. does anyone have a connection pool using example?

alexlpze

@alexlpze_twitter

here is a simple example (I avoid try catch and another code to short the example)

const sql = require('mssql');

async  getCatalogbyId({dbconfig, catId}){
   let pool = await sql.connect(dbconfig);
   let catalog = await pool.request().query(`SELECT * FROM oper.CATALOG WHERE  CATID = ${catId}`);
   return catalog.recordset;
}

has anyone ever ran into TimeoutError: ResourceRequest timed out? how can i fix this without having to restart the node app?

hello everyone

@labs20

Hi. I'm running into ResourceRequest time out too without any plausible clue. Its random, the server is not overloaded (its a test environment). Any ideas or directions anyone? Thanks!

Wellington Rodriguez

@wrod7

i switched all my methods to prepared statements and i don’t get the error anymore. but still would like to have it reconnect when the error is thrown

Labs

@labs20

mmm... thanks for the info. I'll check on that.

But it still sounds a little off, doesn't it?

Jason Luboff

@JLuboff

I am using SQL Express for dev, and was experiencing timeouts (no real rhyme or reason). I was using a named instance. I found that if I went into SQL Server Configuration tool, Protocols section and then in the TCP/IP settings under IP Addresses changed TCP Dynamic Ports to blank and TCP Port to 1433, after restarting the service, no longer have time outs. Don't recall if this is the same type of timeouts you both are refering to...but worth looking into..

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

Labs

@labs20

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

Labs

@labs20

having a hard time with this one.

If someone could help, apreciate. => tediousjs/node-mssql#615

Is your node version either latest 4, 5, 6, 7, 8 or 9 ? i Tried with node version 9.5 in electron atom

John Woodruff

@johnbwoodruff

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?

anyone running graphql with mssql?

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.
