B4J Question MS SQL -> Syspro ERP

I am an absolute DUMMY when it comes to "networking". We are using Syspro and I am trying to connect to it via B4J code but just don't get it right (no problem via ODBC connection or making use of "Launch Power Query Editor" that is available under Excel -> Get Data -> Launch Power Query Editor.

I am connected to the company network (VPN) and my B4J connection code is as follows:

B4X: 
#AdditionalJar: mssql-jdbc-9.2.1.jre11

.....and.....

B4X: 
Dim SQL1 As SQL

.....and.....

B4X: 
SQL1.Initialize2("com.microsoft.sqlserver.jdbc.SQLServerDriver", "jdbc:sqlserver://;servername=xxx-sql-001;databaseName=Syspro_Live_XXX_X", "johans", "xxxxxxxxxx")

But no joy - keep on getting the following error:

B4X: 
com.microsoft.sqlserver.jdbc.SQLServerException: Login failed for user 'johans'. ClientConnectionId:4eece5da-4676-434a-b682-80289365fc6d

Please give some advise on how to solve this issue.....browsed the forum and the web for hours but just do not find an answer to the error....

hi!
this is incorrect:
B4X: 
jdbc:sqlserver://;servername=xxx-sql-001

it should be
B4X: 
$"jdbc:sqlserver://${host}:${port};databaseName=${database}"$

check that sql server has the tcp ip protocol open and check that a fixed port is working too.

config.properties - MS Sql driver for JDBC

I am trying to change the tutorial code for mysql to MS Sql, but I have it wrong. This is my code: DriverClass=com.Drivermicrosoft.sqlserver.jdbc.SQLServerDriver JdbcUrl=jdbc:sqlserver://localhost/test?characterEncoding=utf8 I could not find the correct connection string elsewhere on the...

Have tried this:

B4X: 
SQL1.Initialize2("com.microsoft.sqlserver.jdbc.SQLServerDriver", "jdbc:sqlserver://xxx-sql-001:1433;databaseName=Syspro_Live_XXX_X;", "johans", "xxxxxxxxxx")

...but no joy.

I am not in charge of IT (hosted off site) so not sure how to do this:

B4X: 
check that sql server has the tcp ip protocol open and check that a fixed port is working too.

Same error:

B4X: 
com.microsoft.sqlserver.jdbc.SQLServerException: Login failed for user 'johans'. ClientConnectionId:68164b2b-9141-41f7-afca-bbdb4e526ed7

you have to do it (or ask for someone to do it this way:

At long last got it working.....

B4X: 
#Region Project Attributes
    #MainFormWidth: 600
    #MainFormHeight: 600
#End Region

#AdditionalJar: jtds-1.3.1

Sub Process_Globals
    Private fx As JFX
    Private MainForm As Form
    Private xui As XUI
    Private Button1 As B4XView
    Dim SQL1 As SQL
    Dim res As ResultSet
    
End Sub

Sub AppStart (Form1 As Form, Args() As String)
    MainForm = Form1
    MainForm.RootPane.LoadLayout("Layout1")
    MainForm.Show
    
    Dim connected As Boolean = False
    SQL1.Initialize("net.sourceforge.jtds.jdbc.Driver","jdbc:jtds:sqlserver://xx.x.xxx.xx:1433/Syspro_Live_XXX_X;integratedSecurity=true;useNTLMv2=true;")
    connected = SQL1.IsInitialized
    
    Log("connected = " & connected)

    res = SQL1.ExecQuery("SELECT Customer FROM ArTrnDetail  Where ArTrnDetail.TrnYear = '2022' and ArTrnDetail.TrnMonth = '06';")
    Do While res.NextRow

        Dim datarow(2) As Object
        datarow(0) = res.GetString("Customer")
        Log(datarow(0))
        
    Loop

End Sub

Also had to find and copy ntlmauth.dll into folder C:\Windows\System32 so that it can connect by making use of Window authentication.

B4X: 
connected = true
