: first create the primary database FJJDBBK, and then create a table with the same structure as the current database in FJJDBBK. The best way to create these table structures is to use the Generate SQL Scripts function under the Object menu of Enterprise Manager to Generate the Scripts file for these tables, and then select the FJJDBBK database, run the file using the Query Analyzer function in the Tools me

use the stored procedure, instead of using SQL statements to reduce the overhead of the parser.Database ConnectionTo provide ACID (four features of transactions), SQL Server must ensure that all database changes are sequential. It uses locks to ensure that the insert, delete, or update operations of the database do not conflict with each other (for database lock

Today, a vendor asked me a question. If you want to change the data type of a field in a table, whether it is a field type in View also responds to automatic changes. At that time, I thought it would be changed automatically. However, the vendors said they had tried and won't change it. They asked me if I had any other choice but to try again. At that time, I thought of the storage process sp_refreshview for refreshing the View and asked them to give

database more complex tasks, in excle and other tools can be easily completed. When the contents of the table are modified correctly, the database administrator can import the files from the Excle table directly into the SQL Server database. Because SQL Server is born with

In practice, you sometimes need to import a large amount of data into the database and then use it for various program calculations. In this experiment, we will use step 5 to complete this process and record the time spent by various methods in detail. The tools used in this experiment are VS2008, SQL server 2000, and
