But if you’ve got scrolling errors, it can blow up quickly, and also your archiving strategy here makes a difference. There is an option for extended row size. Let’s create a new table named db2_characters to store the fixed length character strings: CREATE TABLE db2_characters( char_col CHAR (3) ); 1) Insert a fixed-length character string into the CHAR column example DB2 and byte[] primary key columns : Page 1 of 1 [ 8 posts ] Previous topic | Next topic : Author Message; ChrisR Post subject: DB2 and byte[] primary key columns. In your table's definition DB2 will always reserve 312 bytes on the page for the LOB locator; therefore any LOB less than 312 bytes can be stored inline. The row width can be used to estimate table size, and also to pick a tablespace with the correct page size.

SQL Optimizer - Picks different Logicals/Index when same job run twice in a row. Latest DB2 Database topics from Bytes community of DB2 Database experts and professionals. Calculate table and record size. As we have noted, LENGTH works best with single-byte character sets, a multi-byte character may use bytes or char semantics. Where 8 accounts for a header (6 bytes) and an ID map entry (2 bytes). die Geschwindigkeit einer Internetverbindung, werden aber meistens Bits und nicht Bytes pro Zeiteinheit verwendet (Beispiel: 100 Mbit/s). Das Byte ist die Standardeinheit um Datenmengen anzugeben, beispielweise die Kapazitäten eines Speichermediums oder die Grösse einer Datei. You can't set INLINE LENGTH to something less than the maximum size of the LOB locator (i.e. DB2 Diagnostic log (technically, this is DB2 instance level, and not database level): It’s not technically part of the database size, but is at the instance level. The length can be returned in any of the following units: - LENGTH returns Characters - LENGTHB returns Bytes - LENGTHC returns unicode characters - LENGTH2 returns Code units - LENGTH4 returns Code points.

Hello Sandeep Simon, the data type byte count is CHAR as defined (e.g. A DB2 DBA must be able to calculate the row width. 312 bytes for a 2Gb LOB) because it doesn't make sense. DB2 is more strict about a row fitting on a page.
For general purposes, a DB2 table must be in a tablespace where any row, minus LOBs fits on a single page.
