A connection string (whether ODBC or OLE DB) passes information directly to the database, such as server location, database name, type of security, and other useful options. You can define a formatted connection string either in the Access user interface or in VBA code.

OLE DB keyword summary Using ODBC driver or OLE DB providerĬonnection strings have been around a long time. Programmatically interface to SQL Server from Access

The following sections spell out the basics of getting to a database with connection strings and using a database programming interface in your Access VBA code. Keep these happy thoughts in the back of your mind as we take a few tastes of the database version of alphabet soup. The first example shows a connection string that uses SQL Server authentication and the TCP/IP connection protocol.Recall the halcyon days of youth when alphabet soup was your fun meal. Mixed mode simply means you can use either one of the two.įollowing are examples of two different SQL Server connection strings. With Windows integrated security, SQL Server recognizes the same usernames and passwords that are used to log in to the Windows network. This type of security is most commonly used when SQL Server must be accessed from outside the network.

SQL Server authentication means that separate user accounts must be added to SQL Server, and each user must supply a SQL Server username and password to connect. SQL Server can be set to use three types of security: SQL Server authentication, Windows integrated security, and mixed mode. The User ID and Password arguments will be ignored if this argument is present. □ Integrated Security=SSPI -This connection string argument specifies that you want to use Windows integrated security rather than SQL Server authentication. This can be specified on each machine by using the SQL Server Client Network Utility, or you can simply use the Network Library connection string argument to specify the name of the TCP/IP network library, which is dbmssocn. In these cases, the preferred protocol for connecting to SQL Server is TCP/IP. These include accessing SQL Server from a Windows 9x operating system and accessing SQL Server over the Internet. There are many instances, however, where it is not possible to use named pipes. This is required for using Windows integrated security (explained later). □ Network Library=netlib -By default, the SQL Server OLE DB provider will attempt to use named pipes network protocol to connect to SQL Server. □ Password=password -The password for SQL Server authentication. □ User ID=username - The username for SQL Server authentication. This argument will contain the name of the database you want to connect to. □ Initial Catalog=database name -Unlike Access, one instance of SQL Server can contain many databases. If SQL Server is installed as a named instance, the server name will have the following syntax: NetBIOS Name\SQL Server Instance Name. □ Data Source=server name -This will typically be the NetBIOS name of the computer that SQL Server is installed on. The following is a summary of the connection string arguments you will most frequently use when connecting to a SQL Server database: To connect to a Microsoft SQL Server database, you simply specify the OLE DB provider for SQL Server in the ADO connection string, and then include any additional provider-specific arguments required.
