TriggerIs a special type of stored procedure, which is different from the stored procedure. A trigger is executed when an event is triggered. trigger events can be divided into three categories: DML events, DDL events, and database events, stored procedures can be called directly by the stored procedure name. When performing operations such as UPDATE, INSERT, and DELETE on a table, SQL Server automatically runs the SQL statement defined by the trigger, this ensures that data processing must comp

Many of the reasons for using TRIM are that some systems, in order to improve query efficiency, do not use ORACLE's unique, excellent, and never-before-defined VARCHAR2, but use the CHAR type to write dead character lengths. Therefore, in the associated query when depressed, the newly established table on the use of VARCHAR2, if you do not

When using PL/SQL, the first time you open the table, you will be prompted to "dynamic execution table is inaccessible, automatic statistics of this session is forbidden" error, a message is as follows: V$session,v$sesstat,v$statname is not authorized, do not have access to these tables, So there is no statistic in this law.Granted, of course.

to some default settings of the win system, the free database connection of TCP is not released in time after the database connection pool is exhausted. TCP connections continue to increase, slowly exceeding the limit. After the TcpTimedWaitDelay is configured, the TCP connection is automatically freed after 60 seconds of inactivity. As a result, 50 or so stable connections are maintained under normal conditions.I think it should be so, sometimes looking at the database pool useful, but in fact

into it, the table will not immediately allocate extent, that is, it does not occupy the data space, only when you insert the data to allocate space. This can save a little space. When the Deferred_segment_creation parameter is set to False, both the empty table and the non-empty table are assigned segment. It is important to note that this value is set only after the newly added table, which has no effect on the previously established empty table and requires a restart of the database paramete
