The merge view will offer four choices for resolving the conflict: Keep both changes, placing the left before right, keep only the left changes, keep only the right changes, and keep both changes, placing the right before left. in addition the code can be directly edited in the merge view. The Code comparison tool provides four options to solve the conflict: Keep two changes, use the changes on the left, and use the changes on the right. In addition,

1. When comparing a set of records in a certain part of a table, the difference between a common subquery and an associated subquery can be used.

Key point: the key here is the condition of the WHERE clause added to the subquery. This condition specifies that the sales unit price and average unit price of each item ar

logical address, which will send messages to the address, in this way, we can configure the Logical Address of the endpoint as the address for tcpTrace listening, specify another physical address for the server, and configure tcpTrace to forward messages to the physical address. For example, the server configuration is as follows: The client does not need to configure ClientViaBehavior, as shown in the following code: Now "http: // localhost: 8887/CalculatorService" is a logical address.
