You can link to or import more than one table or view in a single operation. Consider the number of columns in each table or view. Access does not support more than fields in a table, so Access links or imports only the first columns.
As a workaround, you can create a view in the SQL Server Database to access the columns beyond the limit. Determine the total amount of data being imported. The maximum size of an Access database is two gigabytes, minus the space needed for system objects. If the SQL Server database contains large tables, you might not be able to import them all into a single Access database. In this case, consider linking to the data instead of importing. Secure your Access database and the connection information it contains by using a trusted location and an Access database password.
Plan for making additional relationships. Access does not automatically create relationships between related tables at the end of an import operation. You can manually create the relationships between new and existing tables by using the Relationships window. For more information, see What is the Relationships window? To import data, select Import the source data into a new table in the current database. You can create a DSN file or reuse an existing one. Use a DSN file when you want to rely on the same connection information for different link and import operations or to share with a different application that also uses DSN files.
Depending on which authentication method you entered in the connection information, you may need to enter a password again. Enter a name for the DSN file, or click Browse to create the file in a different location. Click Next to review the summary information, and then click Finish. In the Description box, optionally enter documentary information about the DSN file.
Do not click the down arrow. With Integrated Windows authentication Connect through a Windows user account. On pages three and four, select various options to customize your connection. A screen appears to confirm your settings. Select Test Data Source to confirm your connection. You may need to login to the database. To change additional settings, select Options. In the Link Tables or Import Objects dialog box, under Tables , select each table or view that you want to link or import, and then click OK.
Security Selecting this option eliminates the need to enter credentials each time you open Access and access the data. But, this stores an unencrypted password in the Access database, which means people who can access the source contents can see the user name and password. If you select this option, we strongly recommend storing the Access database in a trusted location and creating an Access database password.
For more information, see Decide whether to trust a database and Encrypt a database by using a database password. Note If you decide not to save the password, but then change your mind, you need to delete and re-create the linked table, and then select Save Password. In the Get External Data - ODBC Database dialog box, you can save the import steps as a specification and create an Outlook task to automate the import operation on a regular basis.
For more information, see Save the details of an import or export operation as a specification. When a link or import operation completes, the tables appear in the Navigation Pane with the same name as the SQL Server table or view combined with the owner name. For example, if the SQL name is dbo. But you can rename the tables to something more meaningful.
In an import operation, Access never overwrites a table in the database. Although you cannot directly append SQL Server data to an existing table, you can create an append query to append data after you have imported data from similar tables.
In a link operation, if columns are read-only in an SQL Server table, they are also read-only in Access. Tip To see the connection string, hover over the table in the Access navigation pane. If you want to make design changes, do it in the SQL Server database.
To see the design changes in Access, update the linked tables:. Select each linked table you want to update, select OK , and then select Close. Access data types are differently named from SQL Server data types. You can work with data stored in SQL Server either by linking to it or importing the data into an Access database. Linking is a better option if you share the data with others because the data is stored in a centralized location and you can view the most current data, add or edit the data, and run queries or reports in Access.
Locate the SQL Server database that you want to link to. If necessary, contact the database administrator for connection information. You can link to multiple objects at a time.
Access supports up to fields columns in a table, so the linked table will include only the first fields of the object you link to. To create the linked tables in an existing Access database, make sure that you have the necessary permissions to add data to the database.
Note: A linked table created in an existing Access database, gets the same name as in the source object. If Contacts1 is also already in use, Access will create Contacts2, and so on. When linking to a table or view in a SQL Server database, Access creates a new table known as a linked table that reflects the structure and contents of the source table.
Any structural changes to linked tables like removing or changing columns, have to be made from the SQL Server and not Access. In the Select Data Source box, if the. Note: You need write permissions to the folder to save the. Click Next to review the summary information, and click Finish. If you see the Select Unique Record Identifier , it means that Access was unable to determine which field or fields uniquely identify each row of the source data. Just select the field or combination of fields that is unique for each row, and if you are not sure, check with the SQL Server database administrator.
When the linking operation is complete, you can see the new linked table or tables in the Navigation Pane. When you open either a linked table or the source object, you see the latest data. Right-click the table in the Navigation Pane, and then click Linked Table Manager on the shortcut menu. Select the check box next to each linked table that you want to update, or click Select All to select all of the linked tables.
