A simple connect and execute plugins for MSSQL querys on nodejs.
npm install node-mssql-connectorA simple way to connect to Microsoft SQL (MS-SQL) databases from Node.js.
Run queries or stored procedures. Based on tedious by Mike D Pilsbury.
UPDATE, DELETE, SELECT etc.tedious-connection-pool.CurrentVersion: 1.0.0
npm install node-mssql-connector
``js`
MSSQLConnector = require( "node-mssql-connector" );
MSSQLClient = new MSSQLConnector( {
settings: {
max: 20,
min: 0,
idleTimeoutMillis: 30000,
detailerror: true # To show detail error information
},
connection: {
userName: "",
password: "",
server: "",
options: {
database: ""
}
}
})
:`js
Initiliazed client
MSSQLClient.on( "error", function( error ){
// handle error
} );
`$3
First define the query statement.
js
query = MSSQLClient.query( "
SELECT ID, Name, Lastname
FROM Table
WHERE id = @id
")
`Set the parameters. Values with leading
are defined as parameters.
If there aren't any parameter you do not need the following line.
Important You have to use the correct datatype from tedious. They can be found here (column "Constant"): http://pekim.github.io/tedious/api-datatypes.html`js
query.param( "id", "Int", 23 )
`
Execute the query. The result will be returned as an
with an Object for each result.
`js
query.exec( function( err, res ){
if( err ){
console.error( err );
return
}
/*
The result looks like this:
{
result:[
{
id: 23,
name: "Testuser"",
lastname: "Testlast"
}
],
rowcount: 1
}
*/
})
`Since
:
You can also add a list of (Array) parameters into one param statement, e.g. query = MSSQLClient.query( "
SELECT ID, Name, Lastname
FROM Table
WHERE id IN (@idlist)
")
query.param( "idlist", "Int", [23,34,67] )
Check that every parameter in this array has the given type.
Stored procedure
The stored procedure in database looks like:
`sql
CREATE PROCEDURE [dbo].[sp_demo] @ID Int,
@Total Tinyint = 0 Output,
@Teststring Varchar(100) = 'Default' Output
AS
SET @Teststring = "Modifed"
SET @Total = 100
SELECT ID, Name, Lastname
FROM Table
WHERE ID = @id
`The difference to SQL Statment is that you have to call the
method of MSSQLClient. If your stored procedure has output params (like in this example) then you must define this via storedprod.outParamjs
storedprod = MSSQLClient.storedprod( "tedious_get2" )
storedprod.param( "id", "Int", 23 )
storedprod.outParam( "Total", "Int" )
storedprod.outParam( "Teststring", "VarChar" )
storedprod.exec( function( err, res ){
if( err ){
console.error( err );
return
}
/*
The result looks like this. The paran 'output' is only by stored procedures.
{
result:[
{
id: 23,
name: "Testuser"",
lastname: "Testlast"
}
],
output: [
{
Total: 100
},
{
Teststring: "Modifed"
}
],
rowcount: 1
}
*/
