SQL Server
ODBC
Standard Security:
"Driver={SQL Server};Server=Aron1;Database=pubs;Uid=sa;Pwd=asdasd;"
Trusted connection:
"Driver={SQL Server};Server=Aron1;Database=pubs;Trusted_Connection=yes;"
Prompt for username and password:
oConn.Properties("Prompt" = adPromptAlways
oConn.Open "Driver={SQL Server};Server=Aron1;DataBase=pubs;"
OLEDB, OleDbConnection (.NET)
Standard Security:
"Provider=sqloledb;Data Source=Aron1;Initial Catalog=pubs;User Id=sa;Password=asdasd;"
Trusted Connection:
"Provider=sqloledb;Data Source=Aron1;Initial Catalog=pubs;Integrated Security=SSPI;"
(use serverName\instanceName as Data Source to use an specifik SQLServer instance, only SQLServer2000)
Prompt for username and password:
oConn.Provider = "sqloledb"
oConn.Properties("Prompt" = adPromptAlways
oConn.Open "Data Source=Aron1;Initial Catalog=pubs;"
Connect via an IP address:
"Provider=sqloledb;Data Source=190.190.200.100,1433;Network Library=DBMSSOCN;Initial Catalog=pubs;User ID=sa;Password=asdasd;"
(DBMSSOCN=TCP/IP instead of Named Pipes, at the end of the Data Source is the port to use (1433 is the default))
SqlConnection (.NET)
Standard Security:
"Data Source=Aron1;Initial Catalog=pubs;User Id=sa;Password=asdasd;"
Trusted Connection:
"Data Source=Aron1;Initial Catalog=pubs;Integrated Security=SSPI;"
(use serverName\instanceName as Data Source to use an specifik SQLServer instance, only SQLServer2000)
Connect via an IP address:
"Data Source=190.190.200.100,1433;Network Library=DBMSSOCN;Initial Catalog=pubs;User ID=sa;Password=asdasd;"
(DBMSSOCN=TCP/IP instead of Named Pipes, at the end of the Data Source is the port to use (1433 is the default))
Declare the SqlConnection:
C#:
using System.Data.SqlClient;
SqlConnection oSQLConn = new SqlConnection();
oSQLConn.ConnectionString="my connectionstring";
oSQLConn.Open();
VB.NET:
Imports System.Data.SqlClient
Dim oSQLConn As SqlConnection = New SqlConnection()
oSQLConn.ConnectionString="my connectionstring"
oSQLConn.Open()
