Construct recordsets , which select records from tables or queries. Manage transactions , batching updates so all are committed to the data source at once or the whole transaction is rolled back so the data source is unchanged — if the data source supports the required level of transactions.
When you finish working with a data-source connection, you close the CDatabase object and either destroy it or reuse it for a new connection. Skip to main content. This browser is no longer supported. Download Microsoft Edge More info. Contents Exit focus mode. Doing this helps ensure that users are working with the most recent data. Alternatively, you can limit the availability of data from a secondary data connection by setting an expiration date on how long that you want data to be stored on a user's computer.
When you use this option, InfoPath makes the data from all secondary data connections available to the form for only the specified number of days. After that number of days has passed, the data will not appear in the form. You can then add a button to your form that users can click to retrieve data, by using a specific secondary data connection or all of the secondary data connections in the form.
The data will only be overwritten when the operating system uses this space to store something else. Before you add a secondary data connection to a Microsoft SQL Server database to your form template, you need the following information from your database administrator.
The authentication required by the database. The database can use either Microsoft Windows authentication or SQL Server authentication to determine how users can access the database. The name of the table that contains the data that you want to send to the form.
This is the primary table. If you plan to use more than one table in the database, you need the names of those other, child tables. You also need the names of the fields in the child tables that possess relationships to the fields in the primary table.
Once you get this information, you can use the following procedure to create the data connection to a SQL database for offline use. In the Server name box, type the name of the server where the database is stored. If the database determines who has access to the server based on the credentials used in a Microsoft Windows network, click Use Windows Authentication. If the database determines who has access to the server based on a specified user name and password that you get from the database administrator, click Use the following User Name and Password , and then type that user name and password in the User Name and Password boxes.
On the next page of the wizard, in the Select the database that contains the data you want list, click the database that you want to use, select the Connect to a specific table check box, click the name of the primary table, and then click Next. On the next page of the wizard, in the File Name box, type a name for the file that stores the data connection information.
In the Add Table or Query dialog box, click the name of the child table, and then click Next. InfoPath attempts to set the relationships by matching field names in both tables. If you do not want to use the suggested relationship, select the relationship, and then click Remove Relationship.
To add a relationship, click Add Relationship. In the Add Relationship dialog box, click the name of each related field in the respective column, and then click OK.
If you want the data from this secondary data connection to be available even if a user's computer is not connected to a network, select the Store a copy of the data in the form template check box. When you select this check box, InfoPath queries the external data source and stores the results in the form template. Security Note: Selecting this check box stores the query results in the form template.
Because the data is stored in the form template, it is available in the forms that users fill out, even if their computers are not connected to a network. If you are getting sensitive data from this data connection, you may want to disable this feature to help protect the data in case the computer is lost or stolen. On the next page of the wizard, type a descriptive name for this secondary data connection. Verify that the information in the Summary section is correct.
To allow your users to use this secondary data connection when they create a new form or open an existing form based on this form template, select the Automatically retrieve data when form is opened check box. Before you add a secondary data connection to an Access database to your form template, you need the following information from your database administrator.
Note: You will also need to know whether the database is in a network location that is accessible to your users. If other users on the network will create forms based on this form template, your database must be located in a network location that is accessible to your users.
If your form template will only query the database, you will need the name of the table that supplies the results of the query sent to the database. This table will be the primary table when you configure the query data connection. The names of any other tables that the primary table may require data from.
In most cases, the table relationships are already established in the database. If you must establish the relationships between the primary table and another table, you will need the related field names in both tables. Once you get this information, you can use the following procedure to create the data connection to an Access database for offline use.
In the Select Data Source dialog box, browse to the location of your database. Note: If your database is stored in a network location, browse to the UNC path of the location.
Do not browse to the network location through a mapped network drive. If you use a mapped network drive, the forms created based on this form template will search for the database from a mapped network drive. If the user does not possess a mapped network drive, the form will not find the database. In the Select Table dialog box, click the primary table that you want to use, and then click OK.
By default, all of the fields in the table will be added to the main data source of the form template. Under Data source structure , clear the check boxes for the fields that you do not want to include in the main data source.
To make the data from this secondary data connection available even if a user's computer is not connected to a network, select the Store a copy of the data in the form template check box.
