DB2: The last query...

Bodensee/Lake Constance in Winter
I am always amazed at what DB2 is capable of. Today, I would like to show you my last DB2 query for this year. All what is needed comes with the regular DB2 and is even included in the free DB2 Express-C. You could run it in your own DB2, locally or in the IBM DB2 on Cloud service on Bluemix. Enough of introduction, enough of my words for this year, here is my last DB2 query for this year...


[hloeser@magicmachine]$ db2sampl

  Creating database "SAMPLE"...
  Connecting to database "SAMPLE"...
  Creating tables and data in schema "HLOESER"...
  Creating tables with XML columns and XML data in schema "HLOESER"...

  'db2sampl' processing complete.

[hloeser@magicmachine]$ db2 connect to sample

   Database Connection Information

 Database server        = DB2/LINUXX8664 10.5.6
 SQL authorization ID   = HLOESER
 Local database alias   = SAMPLE


[hloeser@magicmachine]$ db2 "select substr(note_text,length(note_text)-36,18) from in_tray where source='CHAAS'"
