Brief introductionWhen it comes to ensuring that enterprise applications built with IBM DB2 (DB2 certified DB2 Training) ®universal Database "(DB2 UDB) and borland® tools (such as Delphi, C++builder, or Kylix) have the best performance, programmers The ability of the DB2 opt

Comparison of concurrency control (LOCK) between DB2 and Oracle Comparison of concurrency control (LOCK) between DB2 and Oracle 1 Introduction The minimal recovery and transaction units in relational databases (DB2, Oracle, Sybase, Informix, and SQL Server) are a transaction (Transactions). Transactions are ACID (atomicity, consistency, isolation, and durability

The so-called data movement in DB2 includes:1. Import Data)2. Data Export (Export)3. Load) Both import and load use DB2 commands to save data in files of a certain format to tables in the database.Export refers to saving the data in the table of the DB2 database to a file of a certain format. The role of data movement: To transfer data between different database

4. DECIMAL (P, S) --- DECIMAL type, where P indicates precision, S indicates DECIMAL places, and implicit DECIMAL places (DECIMAL places are not counted in digits ). For example, MDECIMAL () is the precision of M. 4. DECIMAL (P, S

provided beyond the scope of this article, but the upcoming IBM Systems Journal will discuss the differences between these languages in more detail. Now let's explore some basic aspects of the XQuery language and see how to use it to query XML data in DB2 Viper.

The DB2 tutorial you are looking at is: IBM DB2 Connect Introduction (1). In part 1th of this series, we initially talked about the different programming interfaces provided by DB2 Connect and the drivers that implement those interfaces. In the last few sections, we describe roughly the communication infrastructure provided by

This time, our DB2 is deployed on Windows. Windows has a client that is called a graphical interface. But it does not seem to work well, we have some problems, let's solve it. First, add a database instance: Instances of DB2 are independent of each other, and instances can be considered as containers for databases. When the default DB2 is installed, it builds an

Explanation: mutual conversion of binary, octal, decimal, and hexadecimal values: in addition to the remainder of 2, the integers are arranged in reverse order, that is, each time an integer is divided by 2, and the remainder is the number on the right, the quotient is divided by 2, and the remainder is the number of the previous right. this step continues until the quotient is 0, and the conversion between the first,

Guidance:In recent years, with the improvement of people's living standard, many people have begun to buy insurance, which also accelerates the rapid development of the insurance industry,Insurance IndustryIt is generally oriented to the public, so the database is in a relatively important position for the insurance industry. It is precisely becauseDB2 databaseThe system has many advantages, so some insurance companies choose the DB2 database system.

DB2 data type description DB2 built-in data types can be divided into numeric type (numeric), character type (character string), graphic string, binary string type (binary string) or datetime ). There is also a special data type called datalink. The datalink value contains logical references to files not stored in the database. Numeric data typeIncluding smallint, integer, bigint,
