Had a great morning building snow forts and a snowman with the girls. Once again realized how fortunate we are when our neighbor brought over the snowman kit shown here so we didn’t have to use the jack-o-lantern kit we were using. 🙂

Hey, it’s not a picture about snow! Did have the opportunity to meet with a valued partner with Churchill Mortgage today!

How Much Space Is Being Used by 1 LOB / CLOB / BLOB in DB2

Building off of yesterdays lesson on how to determine how much space a table is using (including LOBs and Indexes), there may come a time when you need to determine how much space 1 or more specific records are taking up. To do that, use the LENGTH() function which will return you how many bytes the field is using. Simply do some math to get a more useful value (like KB).

SELECT length(LOB_DATA_X) BYTE_A, length(LOB_DATA_X) / 1024 KB_A
FROM XX.MY_TABLE
FETCH FIRST 10 ROWS ONLY WITH UR FOR READ ONLY;

Get Space Used by LOB / CLOB / BLOB in DB2

If you have a DB2 table and want to get information as to how much space a particular table is using, you could try and deduce it from things like the row length, or you could just query the view via a table function and make your life a heck of a lot easier.

For instance, start with something like this…

SELECT * FROM TABLE(SYSPROC.ADMIN_GET_TAB_INFO('XX', 'MY_TABLE'));

Previous versions of this function include ADMIN_GET_TAB_INFO_V97 and ADMIN_GET_TAB_INFO_V95. The nice thing is that it appears you don’t have to be a DBA to query the info which is nice for us app developers out there!

Keep in mind that sizes returned are in KB, so you may want to convert the data to something more useful like so…

SELECT  TRIM(TABSCHEMA) || '.' || TRIM(TABNAME) AS TABLE_NM,
        DATA_OBJECT_P_SIZE / 1024 AS DATA_P_SIZE_NB, 
        LOB_OBJECT_P_SIZE / 1024 AS LOB_P_SIZE_MB, 
        XML_OBJECT_P_SIZE / 1024 AS XML_P_SIZE_MB, 
        LONG_OBJECT_P_SIZE / 1024 AS LONG_P_SIZE_MB, 
        (DATA_OBJECT_P_SIZE + LOB_OBJECT_P_SIZE + XML_OBJECT_P_SIZE + LONG_OBJECT_P_SIZE) / 1024 AS TOTAL_P_SIZE_MB,
        INDEX_OBJECT_P_SIZE / 1024 AS INDEX_OBJECT_P_SIZE_MB
FROM TABLE(SYSPROC.ADMIN_GET_TAB_INFO('XX', 'MY_TABLE'));
