1. Character functions:
The characters in SQL Server are case-insensitive.However, the lower and upper functions are common in SQL Server, Oracle, and DB2. For example, select empno, ename, deptno from EMP where upper (ename) = upper ('bucket ');

This article mainly describes the actual operation steps for correctly creating the DB2 SQL stored PROCEDURE (create procedure (SQL) statement). First, we start with the syntax format, at the same time, there is a description of its syntax. The following is the main content of the article.
The syntax format is as follows:

What we will tell you today is how to use the DB2 database function in Domino7.x to find the correct explanation of the SQL error code. Its product is Lotus Domino Designer, and the platform is unrelated to the version: 7.x. the following articles will provide you with relevant knowledge.

DB2 does not exist in the explain table of the SQL Execution Plan by default. Therefore, you need to create an explain table as needed during use. How can you create it? In fact, DB2 still provides a variety of methods for you to use. The first method is to use the script EXPLAIN. DDL by default, which is created in the following path of the database by default:
= 2084
Available pages = 2084
Used pages = 2084
Unused pages = not applicable
High water mark page) = not applicable
Page size, in bytes) = 32768
Expanded data block size page) = 32
Prefetch size page) = 32
Container COUNT = 1
The value of pagesize is already relatively large. You can consider increasing the tablespace.
How to expand the existing table space in DB21) Example of directly adding a container:Db2 "alter tablespace tpms add (DEVICE '/dev/rhdisk9' 10000 )"After adding a container,
This article describes how to execute SQL scripts in the DB2 command window for your reference.
You can run SQL scripts in the Command Editor, DB2 command window in Windows, or shell in Linux. Run the following SQL statement in the windows
After the last write, how do I export the data structure and data ([Tips] exporting table structures and data from DB2). Now I have finally finished writing how to import the table structure.
The first step is to create a database. You can use control center or command line. However, for this new database, I prefer command editor.After opening, you can directly write the following SQL text:Create Database m

The following articles mainly describe the basis of the DB2 SQL stored procedure. The stored procedure is simply procedure. To learn this, we must first understand another concept: routine, which is generally translated into "routines ".
Routine: database objects that exist on the server and are written according to the application logic and can be called through the client or other routine.

The constraint is used to force the row data to meet specific business rules (the data type is to force the column data to meet the rules)There are five types of constraints: • not null • unique • primary key • Foreign key • check the not null constraint on SQL Server: • Create Table u_emp (• empno bigint, • ename varchar (10) Not null, • job varchar (9), • Mgr bigint, • hiredate date, • Sal decimal (7,2), • comm decimal (7,2 ), • deptno decimal (7,2)
Mixed character data and graphic data is always allowed for Unicode, but for EBCDIC and ASCII, the specific installation of db2®determines whether mixed data can be used.The field MIXED DATA on installation panel DSNTIPF can has the value YES or NO for ASCII or EBCDIC character strings. The value YES indicates that character strings can contain a mixture of SBCS and DBCS characters. The value NO indicates that they cannot. Mixed character data and gra
The paging query method of DB2 is not the same as that of paging query statements in Oracle and SQL. The following describes the differences between paging query in DB2 and paging query in other databases.
