Add FETCH FIRST n ROWS ONLY (FFRO) to ARRAY_AGG function
This would work along the same lines as ORDER BY in the ARRAY_AGG and will restrict the number of array elements. I believe this feature would be a feature in demand as more DB2users utilize DB2 arrays. I had to resort to a workaround of using a s...
One of the frequent questions I receive from application teams, when dealing with XML data is : What is the max size of my xml documents in database ? What is the average size of them ? Today, Db2 has no easy answer for that.. the LENGTH() functio...
Improve precision for CURRENT_TIMESTAMP on windows
when asking for the CURRENT_TIMESTAMP on Unix systems, we have 6 decimal precisions for the timestamp value. yyyy-mm-dd HH.mm.ss.nnnnnn - TIMESTAMP(6) but for windows, current_Timestamp just provides a milisecond precision yyyy-mm-dd HH.mm.ss.nnn ...
My result set final format needs to be CSV. It would be awesome if I could use SELECT CSV(*) FROM TABLEA to return my result set as a column of CSV format. so for instance I have a requirement to produce a csv file of variable record lengths SELEC...
Competitive databases like Oracle, PostgreSQL and SQL Server along with others have data type TIMESTAMP with TIME ZONE but LUW does not. Our own DB2 on z/OS starting version V11.0 has TIMESTAMP WITH TIMEZONE.
In reference to this Db2 for z/OS idea (link), we need the same functionality for all platforms including Db2 for LUW.
I quote the text from the other RFE:
Currently there is documented maximum timestamp value available in DB2 as '9999-12-31-2...
A lot of applications using unix timestamps (number of seconds since 1970-01-01). For example DMC (Data Management Console) is using this. For DBAs and application developer it would be much easier to have a builtin function to convert this unix t...
Allow data type ROW CHANGE TIMESTAMP in column-organized tables
We need the ability to define columns with data type ROW CHANGE TIMESTAMP in our tables so that we can track when the last change was made. Currently we use normal row based tables which allow this but we want to migrate to column based tables. Wh...
National character data type support in non-unicode database like Oracle
Kookmin Bank is doing migration project from Oracle.
Oracle based on national codepage such as MS949 supports the unicode data types such as NCHAR, NVARCHR, NCLOB.
Now Db2 supports them in Unicode database. The requirement is asking to enable at...
