The Specify how to select and modify data setting allows you to configure how to select and modify the data you want to be included in the synchronization process:
-
Use data from this table: Allows you to select a database table that includes the data you want to participate in the synchronization operations. You can click Preview to preview the database table you have selected.
-
Use an SQL query to specify data: Allows you to compose an SQL query that provides a more flexible way for specifying the data for synchronization. For example, you can use this option to specify multiple database tables.
-
Configure Settings: Specifies the settings for modifying data in the connected system during synchronization operations. For example, you can specify the database tables in which you want to insert, update, or delete data during synchronization operations.
Allows you to configure the running timeout for all SQL queries you specified in the connection settings (for example, those specified in the Specify How to Select and Modify Data option). Use the SQL query execution timeout box to type the timeout value you want to use.
The Specify attributes to identify objects setting provides the following options that allow you to specify the attributes with which you want to uniquely identify each object in the connected data system:
-
Available attributes: Lists the attributes that are available in the external data system. Use this list to select the attributes whose values you want to use to generate a unique identifier for each object in the external data system. You can filter attributes by typing in the text box at the top of this list. To select multiple attributes, hold down CTRL and click to select attributes in the list.
-
UniqueID attributes: Lists the attributes whose values are currently used to generate a unique identifier for each object in the external data system.
-
Add->: Moves the selected attributes from the Available attributes list to the UniqueID attributes list.
-
<-Remove: Moves the selected attributes from the UniqueID attributes list to the Available attributes list.
-
Constructed UniqueID: Displays a combination of the attributes whose values will make up a unique identifier for each object in the external data system.
This section provides some sample SQL queries illustrating how to modify SQL Server data during synchronization operations. In the sample queries, Id refers to an attribute (a column name in an SQL Server table) that uniquely identifies an object in your SQL database. These examples can be used only for configuring connections to Microsoft SQL Server 2005.
Example: Inserting an object into a table
This sample illustrates how to create a query that inserts an object with specified attributes into the table named SQLConnTest1.
Table 41: Inserting an object into a table
|
CREATE TABLE [SQLConnTest1]([Id] [bigint] IDENTITY(1,1),[attr1] [nchar](64),[attr2] [nchar](64))) |
INSERT into SQLConnTest1(Id) values(@Id) |
Example: Creating an SQL Server account
This sample illustrates how to create a SQL Server account, and then retrieve the UniqueID attribute for that account.
To define the scope where to create the SQL Server account, insert the following query in the Query Editor dialog:
SELECT sid as Id,name as login from sys.server_principals
Insert the following SQL query into the Configure SQL Statements dialog:
EXEC sp_addlogin @login, @newPassword;
EXEC sp_adduser @login,@login,'db_owner';
SELECT sid as Id from sys.server_principals where name=@login;
IMPORTANT: None of the attribute names used in SQL queries can include whitespace characters. For example, you cannot use names such as "user password".
