It is very important to develop a database application and select a good database. This article compares three types of databases: SQL Server, Oracle, and DB2. It provides some reference for you to select a database. 　　 　　 Openness SQL Server It can only run on windows without any openness. The stability of the operating system is very important to the database.

SQL Server versus Oracle, DB2 vs. Pros: 1. Openness: SQL Server Can only run on Windows, without the slightest openness, the stability of operating system systems is very important to the database.

The main difference between the writing of DB2 and oracle SQL statements is to be honest. ORACLE has spoiled domestic programmers, and the SQL statements in the Code are filled with a large number of ORACLE features. Almost no one knows what the ANSI standard SQL looks like, as a result, the program cannot run without

You can also reduce the length of one or more columns to reduce the row length. For example, the executed SQL statement is Alter table tpms. tpms_target alter column "target_value_by" set data type varchar (4000 ); If an error is reported, you can set a smaller value of varchar (2000), so that the execution is succ

For a geographically dispersed large enterprise organization, to build a large enterprise management information system with typical distributed computer features, it is always necessary to solve a very important problem: how to ensure the consistency of shared data among different database servers. The important problem is that the organization changes the local database with the same structure in different locations, but it is necessary to ensure that the modified database has the same result,

DB2 tuning SQL Execution Analysis I have always had a misunderstanding that it is the same to not creating indexes for all the fields in the table. Therefore, when the data volume reaches 1 million in a practical application, the retrieval speed is obviously slow, and the CPU usage during query execution is very high, which affects other jobs and leads to chain reactions.After discussing with some friends,
