DB2 conditional processors play an irreplaceable role in stored procedures. In DB2, SQL stored procedures can use the DB2 conditional processor Condition Handler) to handle SQL errors in the stored procedure running SQLERROR), SQL

The main differences between DB2 and ORACLE SQL notation To be honest, Oracle has spoiled the country's programmers, and SQL in the code is flooded with Oracle features, and almost no one knows what ANSI's standard SQL looks like, leaving the program out of Oracle at all, and the situation has changed dram

This article mainly describes several ways to use SQL statements to track DB2 databases. I saw several ways to use SQL statements to track DB2 databases on the relevant website two days ago, let's share it with you. I hope you will have a better understanding of it after browsing. 1. Use

DB2 SQL statements are familiar to everyone. Good DB2 SQL statements make the database performance more stable. So how should we optimize DB2 SQL statements? The following sections will show you the answer. The operations perform

This article describes the correct implementation process of connecting SQL Server databases to the DB2 connection Server. We all know that the interconnection between different database platforms is a heterogeneous database service, currently, all major databases can achieve such Heterogeneous Interconnection, but the specific implementation technologies of different vendors are different, such: In

The following articles mainly introduce the implementation process of connecting the SQL Server database to the DB2 connection server.

This article mainly describes the DB2 SQL stored procedure and the authoritative grammar guide. The following is a detailed introduction to the DB2 SQL stored procedure and grammar authoritative guide. The first step is to CREATE a SQL stored PROCEDURE (

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. Windows9x Series products are focused on desktop applications, NT server only for small and medium enterprises. And the reliability, security, and scalability of Wi

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

' 2000, devic'/dev/rcont1 '2000, FILE 'cont2' 2000 )"Note that this method is to change the size of the original container to 2000 pages. 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

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,

In IBM's relational database product DB2, SQL Communication Area (SQLCA) is used to return nested SQL statement execution in the program to the program.In the program is targeted to the SQLCA implementation of the call, you can control the execution of various types of SQL statements in the program, so as to avoid unex

The interconnection of different database platform is commonly called the heterogeneous service of the database, now each big database can realize such heterogeneous interconnection, but the specific implementation technology of each vendor is not the same, such as: In SQL Server called linked server, through ODBC and other database interconnection. The test environment for this article is: Operating system: WINDOWS2000 SERVER (Traditional system)

The basic syntax for most database statements is the same, but specific to each database, there are some differences, such as triggers, DB2 and SQL Server two are very different.For example, a trigger for DB2:CREATE TRIGGER eas.trname NO CASCADE before insert//INSERT trigger on EAS. T_user referencing new as N_row//Name the newly inserted data as N_row for
