Detailed configuration of the IDC charging system and detailed configuration of the Charging System

Before you knock on the data center charging system, we need to configure the original system for use. The following is a detailed description of my installation. Please kindly advise on the missing information!

1. Configure SQL sever and attach the database.

① Start SQL sever Enterprise Manager, select the database, right-click it, and we can see "additional" and click it.

② Click Add ".

③ Select the "charge_sys_Data.MDF" file and click Add.

At this time, an error is reported. The following dialog box is displayed:

This is caused by insufficient users permissions.

The solution is as follows:

Right-click the folder where the system is located, and select "properties"> "security"> "users"> "edit"> "allow" in "full control, click OK.

Next, on the "APPEND" Page, add it.

Test successful!

The charge database is successfully added to the ingress.

Click "Next" here"

⑩ Use the SQL Server to verify the login ID and password entered by the user. Login ID: sa password: 123456, next step

Next, you must use a switch for case selection;

In this way, beginners may not be puzzled,
As a person who has been here, I must give a suggestion: I must lay the foundation well. This is like Zhang Wuji practiced jiuyang's power, and then practiced everything quickly. internal strength is a basic skill and internal strength is good, it's up to you to be tempted, changing, but you can't leave it alone;
