Introduction

 We are going to discuss establishing an

connection to a SQL Server Database

 You will learn that there is an easy way and a hard way

Overview – What do you have to know…

Security Modes

There are two types of modes:

 Standard Mode (default)

 Integrated Mode

Standard and Integrated Security

DATABASE

Database Security Users, Groups, Permissions

Database Interfaces

DB-Library ODBC

Sources

Connecting to a SQL Server Data Source

 Connecting with Data Control

 Connecting with ADO Data Control (ADO)

 Connecting with ADO Data Control (DSN)

 Connecting with ADO Data Control (UDL)

 Connecting with ADO (Programmatically)

Connecting with Data Control

 Natively it can’t be done…

 However…

Server database, then we can connect to that.

 Downside

 DEMO

Connecting with ADO Data Control (ADO)

 Natively it connects fine

 Set the Connection string property

 Set the RecordSource property

 DEMO

Connecting with ADO Data Control (DSN)

 Natively it connects fine

 Set the Connection string property

 Set the RecordSource property

Data Source Name (DSN)

A DSN is a registry entry (Machine DSN) or text file (File DSN) that contains information about a

database and the SQL Server it resides on.

Control Panel ->

Administrative Tools -> Data

Sources (ODBC)

Start Menu -> Administrative

Tools -> Data Sources

(ODBC)

Demo – Setting up a Data Source Name

Example of a File DSN (Standard)

Example of a File DSN (Integrated)

DEMO – ADO Control with DSN

Connecting with ADO Data Control (UDL)

 Natively it connects fine

 Set the Connection string property

 Set the RecordSource property

Creating a UDL

 Create a file with a UDL extention

 Double-click on the icon

Set the Provider

Set the Connection and Test

Examine the UDL

[oledb]

; Everything after this line is an OLE DB initstring

Provider=SQLOLEDB.1;Integrated Security=SSPI;Persist Security Info=False;User ID=sa;Initial Catalog=pubs;Data Source=dalgoodwin3\dalgoodwin32000

Look familiar?

Can you say “ Connection string”

DEMO – ADO Control with UDL

Connecting with ADO (Programmatically)

 Declare an ADO connection object

 Set the Connection String

 Open the Connection

 Instantiate the recordset etc…

DEMO – Connect with ADO

Other ways

 RDO – Similar to ADO Use DSN or DSN-less connection strings

 ODBCDirect – Too much for this lesson

 ODBC – lots of API calls Better off with the ADO abstraction
