The performance of the SQL statement is measured in MSSQL server by looking at the time it took to execute the SQL statement.By setting STATISTICS We can view the system situation when executing SQL. The options are Profile,io, time. Introduced as follows:SET STATISTICS profile on: Displays the time, in milliseconds, that is required to parse, compile, and execut

If you want the scheduled job to start automatically, find SQL Server agent (MSSQLSERVER) in the service, set to "automatic" modeStep three: Generate scripts for scheduled jobsMethod 1, click the job under SQL Server agent, select the job you created--right-write the job script--create to, and then copy the scripting languageMethod 2

Scene: The DBA gave me the creation scripts for all the storage, functions, and so on, with thousands of files. Now you need to import these object creation scripts into another library, how do you solve them? Manual execution is obviously not realistic. So manually wrote a batch, all the files into one. SQL scripts, which are generated at the end of @. SQL scrip

I don't know if the stored procedure can be implemented, but the job scheduler for SQL Server 2000 does have the ability to make certain SQL statements run at regular intervals, and then do the following:Enterprise Manager--Management--sql Server Agent--Right key job--New job--Enter the job name in the general item--"Step" item--New--Enter the step name in step n

makes some changes in a database based on some business logic. Before you run the code block to change the data, you need to create a database backup that can roll back these changes at any time you need. Because we do not want to give more permissions to the user who is going to execute the stored procedure, we will use the EXECUTE AS clause to play an account with more privileges, have the account do a database backup, and use the revert clause to switch back to the caller's original

PrefaceIn real-time computing, the raw data is usually collected from the queue, which is usually a Java bean in memory, and when the data is collected, the data is usually landed on the database for subsequent ETL use. To give a simple example, for a game, to count a game, a server's login registrationEvents, the Java bean corresponding to the original data might be the same: Public class Event { private String userName; Private String game; Private String server; Private String

server| Create | scripts | asynchronous | execute Application Scenario: Many complex update queries are time-consuming in a large database. In order to avoid the user waiting for a long time, those time-consuming operations can be performed asynchronously, immediately return the execution information to the user, while performing operations in the database background, wait until the completion of the data table update. Development environment:

another function, the first parameter is a column in the table, a map object, and the second parameter is the portion of the AST that is parsed by SQL, corresponding to the WHERE clause. GroupBy clauseGroupBy operations for collections are also available in Scala, followed by the previous exampleScala> L groupBy (_%2) = Map (1, List (1, 3, 5), 0, List (2, 4, 6))Above this function, the L this list is grouped according to the parity.In the Scala _

When executing a stored procedure, we often encounter execution timeout. If there are too many data to be processed and the modification process is complicated, use the following methods to solve the problem: Add transaction management to the processing of stored procedures: SET transaction isolation level Repeatable read ---> need this lineBegin tran /* Here isProgramProcessingCodeSegment */ Commit transactionQuitwithrollback:If (@ tran
