We all know that Latch is the mechanism that Oracle uses for serial control in memory. From 10g R2, Oracle introduced a new technology-Mutex. Mutex is not an invention of Oracle, but an underlying call provided by the system. Oracle only uses it to implement serial control and replaces some Latch. Mutex has two variabl
Author: runming QQ: 226399587 http://blog.csdn.net/runming918As an important mechanism in oracle, SCN (System Chang Number) plays an important role in Data recovery, Data Guard, Streams replication, and synchronization between RAC nodes. Understanding the operating mechanism of SCN can help you gain a deeper understanding of the above functions.Before understanding SCN, Let's first look at how data changes in orac
As a DBA of an Oracle database, deploying an Oracle database is a basic skill. What should be included in the complete deployment of an Oracle database? The following is a brief discussion. 1. Set up the basic environment. The key to this step is to ensure that the Network and storage configurations required by the database are complete and can be accessed normal
After looking at a number of paging stored procedures, it was found to be for SQL Server, without Oracle, so I wanted to write a stored procedure about Oracle because the database I used was Oracle. --------------------------------------------------------------------------------------------------------------- ------------------------------------------------------

According to the jdk jdbc documentation, the resultset: setfetchsize () function syntax sets the number of rows that should be obtained from the database for this resultset object when more rows are required for the JDBC driver. If the specified retrieved size is zero, the JDBC driver ignores this value and arbitrarily guesses the obtained size. The default value is set by the statement object of the created result set. The size can be changed at any time. However, when the
Transferred from: http://database.51cto.com/art/201010/231561.htmOracle queries are sometimes constrained by conditions such as capitalization. Here's a way to implement an Oracle query that ignores case, so if you're interested in Oracle queries, you might want to take a look at this. The database has 4 records, respectively ' KKK ' KKK ' ' KKK ' KKK ' (1) SELECT * from T_vvip t where T.name=lower (' K

Similar to other database systems, Oracle string concatenation uses the "| |" string concatenation, which is used in the same way as the plus sign "+" in MSSQLServer. For example, execute the following SQL statement: Copy Code code as follows: SELECT ' work # for ' | | fnumber| | ' The employee's name is ' | | FName from T_employee WHERE FName is not NULL In addition to "| |", Oracle
In Oracle/plsql, the InStr function returns the position of the string to be intercepted in the source string. The syntax is as follows: InStr (string1, string2 [, Start_position [, Nth_appearance]]) String1 the source string to find in this string. String2 the string to find in the string1. The start_position represents where the string1 starts looking. This parameter is optional, if omitted defaults to 1. The string index starts at 1. If this parame
