excel – VBA Runtime Error when connection to SQL Database

Posted by: admin May 14, 2020 Leave a comment


I’m trying to connect to a SQL Server from multiple PCs in the same domain.

When using the following code:

Dim conn As ADODB.Connection

Set conn = New ADODB.Connection 'Neue Verbindung initialisieren

'Verbindung einrichten'
conn.ConnectionString = "PERSIST SECURITY INFO=True;Provider=SQLOLEDB.1;Server=WWDDB;Database=01Projekt;User ID=XXX;Password=XXX;Trusted_Connection=True;Integrated Security=SSPI;"

conn.Open returns the error:

Error on login for the user ‘XXXX’

How to&Answers:

The issue is because you are using a named user with Integrated Security. These two modes are incompatible.

Try removing Integrated Security=SSPI:

conn.ConnectionString = "PERSIST SECURITY INFO=True;Provider=SQLOLEDB.1;Server=WWDDB;Database=01Projekt;User ID=XXX;Password=XXX;Trusted_Connection=True;" conn.Open

Or the named user:

conn.ConnectionString = "PERSIST SECURITY INFO=True;Provider=SQLOLEDB.1;Server=WWDDB;Database=01Projekt;Trusted_Connection=True;Integrated Security=SSPI;" conn.Open


this is my snippet, try it :

Set cnConn = New ADODB.Connection

With cnConn
.Provider = "SQLOLEDB.1"
.CursorLocation = adUseClient
.ConnectionTimeout = 0
.Properties("Data Source").Value = ' serverName
.Properties("Password").Value = ' pswd
.Properties("User ID").Value = ' userName
.Properties("Initial Catalog").Value = ' init DB
End With
