There is such a view, probably as follows: This view can only be compiled successfully in a 10g,11g environment and cannot be compiled in 9i environments. The code is as follows Copy Code Select a.*,b.*From (select Id,name from a)Left join B on a.id=b.id; The view can be compiled successfully in a 9i,10g,11g environment. The code is as follows Copy Co

Today, the customer wants to use Oracle 9.2.0.5, which is no longer supported by aix 6.1, so he has to copy the software from other databases and recompile it. However, you can only create a database manually. I haven't used manual database creation for a long time. I simply recorded the database creation process. 1. Set the oracle user environment Su-oracle Expo

This article discusses how to use ado.net to access Oracle stored procedures (called SQL programming Blocks) and functions (a programming block that returns a single value). You can connect to an Oracle database using the following managed data provider: Microsoft. NET Oracle provider, OLE DB. NET provider, ODBC. NET data provider, and Oracle's Odp.net provider.

Starting with Oracle 9i, Oracle allows you to make a reputation for primary keys, unique keys, and foreign KEY constraints for view. The NOT NULL constraint can inherit from the base table, so it is not allowed to display the declaration. Because the view constraint is just a declaration, its state can only be disable novalidate. The following is a simple examp

The process of 3.5.1 server shutdown The system completes the following steps when you close the database routine. 1. The first phase Oracle writes the contents of the buffer to the redo log file. Writes the changed data in the database buffer to the data file. Closes the data file and the redo log file. The control file is still open and the database cannot perform a general access operation. 2. Phase II Closes the database. The routine begins unload

I SELECT a table in a production test database when a ORA-01578, a block damage, previously learned how to deal with block damage, to really have not met, today finally let me met, it's still a production test database, so you don't have to be nervous. The database version is 9.2.0.4. The RMAN command of Oracle9i has a blockrecover command to fix bad Blocks online. The following describes how to fix Bad blocks using RMAN.

Why the lock concept is introduced What is a lock The management and allocation of all Oracle 9i locks is done automatically by the database management system, which does not require user intervention, but also provides manual locking commands for experienced users. Classification of Locks 1. Divide by permissions Exclusive lock Shared locks 2. Division of resources by lock allocation Data lock Dictionary l

procedure that returns a single value The Executeoraclescalar () method of the OracleCommand class is used to execute an SQL statement or stored procedure that returns a single value as a OracleType data type. If the command returns a result set, the method returns the value of the first column in the first row. If ref CURSOR is returned, rather than returning the value of the first row of the first column pointed to by ref CURSOR, the method returns a null reference. The ExecuteScalar () meth
