Multiple Cases Access Utilities1 Access & ODBC Managing and Using ODBC Connections P.O. Box 6142 Laguna Niguel, CA

Multiple Cases Access Utilities2 Linked Tables P.O. Box 6142 Laguna Niguel, CA

Multiple Cases Access Utilities3 Linked Tables Powerful feature of Microsoft Access Very widely used Sets up “pointers” in the database Can link to text, Excel, dBase, etc. Another type of data source is ODBC

Multiple Cases Access Utilities4 ODBC P.O. Box 6142 Laguna Niguel, CA

Multiple Cases Access Utilities5 ODBC ODBC = Open Database Connectivity Microsoft supplies a generic middleman driver with Windows Vendors supply drivers for their specific database or data source This enables Access to link to data in almost any kind of database including Oracle, MS SQL Server, DB2, MySQL, etc.

Multiple Cases Access Utilities6 Linking Tables Via ODBC P.O. Box 6142 Laguna Niguel, CA

Multiple Cases Access Utilities7 Linking to ODBC tables 3 scenarios The ODBC connection (DSN or Data Source Name) exists already (perhaps provided by IT group) Create the DSN in advance via Windows Create the DSN connection while going through the link table procedure

Multiple Cases Access Utilities8 Launch Link Tables Dialogue (Existing DSN scenario, Scenario 1)

Multiple Cases Access Utilities9 Link Dialogue Select files of type ODBC

Multiple Cases Access Utilities10 Select Existing Data Source

Multiple Cases Access Utilities11 Login to Data Source

Multiple Cases Access Utilities12 Select Tables to Link

Multiple Cases Access Utilities13 Access Database Window with Linked Tables

Multiple Cases Access Utilities14 Create New Windows DSN (Scenario 2) As stated before DSN typically created well in advance by IT But…for illustration purposes we will create it ourselves This scenario thus has two major steps 1 – create the DSN under Windows 2 – Launch the link tables dialogue in Access and proceed. We have already done this, so this will not be repeated here

Multiple Cases Access Utilities15 Key DSN Properties Name Driver Database Name Authentication Method User Name/Password (if using SQL Server authentication)

Multiple Cases Access Utilities26 Rocky2 DSN Tests OK

Multiple Cases Access Utilities27 Rocky2 DSN now available Note: the rocky2 DSN is available for all applications that can use ODBC, not just Access

Multiple Cases Access Utilities28 Link Tables (Use created DSN; still in second scenario) We will now go through an abbreviated series of slides showing how the new DSN can used.
