What is a Clustered Index table?

ε祈祈猫儿з 提交于 2019-12-05 12:54:27
I may be wrong, but it seems to be different opinions in the interwebs about what these are. SQL Server, MySQL, DB2, and PostgreSQL show different definitions for these tables. After reading a ton from different vendors (database manuals, user posts, etc.) I was able to distinguish three types of tables of interest (there are many, many more types of no interest for this question). Please bear with me: Heap Table : All rows are stored (probably unordered) in the heap table. Each row has an internal ROWID that identifies it. Indexes are optional. If added, they include the indexed columns as

DB2/iSeries SQL clean up CR/LF, tabs etc

百般思念 提交于 2019-12-05 12:38:50
I need to find and clean up line breaks, carriage returns, tabs and "SUB"-characters in a set of 400k+ string records, but this DB2 environment is taking a toll on me. Thought I could do some search and replacing with the REPLACE() and CHR() functions, but it seems CHR() is not available on this system (Error: CHR in *LIBL type *N not found). Working with \t, \r, \n etc doesn't seem to be working either. The chars can be in the middle of strings or at the end of them. DBMS = DB2 System = iSeries Language = SQL Encoding = Not sure, possibly EBCDIC Any hints on what I can do with this? If you

How to get the last insert ID from a table

Deadly 提交于 2019-12-05 10:13:22
问题 I want to get the value of the last ID insert in a table. How I can do this? 回答1: Well the solution that I use is: select id from NEW TABLE (insert into (val1, val2, ...) values ('lorem', 'ipsum', ...)) This gets the id column from the last row inserted in the DB :) 回答2: SELECT IDENTITY_VAL_LOCAL() AS VAL FROM SYSIBM.SYSDUMMY1 See docs. 回答3: Have a look at this answer. http://www.sitepoint.com/php-database-db2/ // get the last inserted ID into the specified table // int lastInsertID(string

DB2 VARCHAR unicode data storage

眉间皱痕 提交于 2019-12-05 09:15:18
We are currently using VARCHAR for storing text data in DB2 however we are hitting the problem that length of VARCHAR specified is not the same as length of text because in DB2 VARCHAR length specified is UTF-8 data length which can vary depending on stored text data. For example some texts contain characters from different languages and because of it some texts with 500 characters can't be saved in VARCHAR(500) and etc. Now we are planning to migrate to VARGRAPHIC. I need to know what are limitations of using VARGRAPHIC for storing unicode text data in DB2. Are there any problems with using

Insert BLOB using java for both DB2 and Oracle

南笙酒味 提交于 2019-12-05 08:16:24
I am currently validating an application developed on Oracle for DB2. Since we don't want to maintain two separate sources, I need some query to insert blob into a field, that works in both oracle and db2. I don't have any identifier to distinguish under which DB the application is running. I used utl_raw.cast_to_raw in oracle and CAST() as BLOB in DB2 which are mutually incompatible. You won't be able to find a common SQL that uses some kind of casting. But you can do this with "plain" SQL using JDBC's setBinaryStream() PreparedStatement pstmt = connection.prepareStatement( "insert into blob

Increment a sequence twice in DB2

落爺英雄遲暮 提交于 2019-12-05 05:33:29
问题 I need to get the next value of a sequence twice in DB2 (version 9.1). Rather than executing the following twice: SELECT nextval FOR schema.sequence AS id FROM dual I would like to do something like: SELECT nextval FOR schema.sequence AS id1, nextval FOR schema.sequence AS id2 FROM dual Except the above only increments it once: ID1 ID2 ----------- ----------- 643 643 1 record(s) selected. Am I forced to just query twice, or is there a way to increment it twice in 1 query? 回答1: This is a a
