Please, could someone give me some examples for these functions? I'd like to see them working and what everyone do. Cheers The availlable functions depend on the type database you are connected to. The bare minimum of functions in the file based databsaes (spreadsheet, text, dBase) is documented here: http://www.openoffice.org/dba/specifications/file_based_functions.html File based databases support only one aggregation COUNT(*) The built-in HSQL 1.8 (which should better not be used embedded into the Base document) is documented here: http://www.hsqldb.org/doc/1.8/guide/ch09.html Any resource on SQL can teach you how to use all these functions properly, particularly the aggregation funcions together with GROUP.

Well, I was not meaning to SQL, because what I want to do right now are queries using the gird, the queries window. The grid (do you mean the design view?) creates an SQL statement as you can see when you toggle between the design view and SQL view. There is a toggle option in the menu and on the toolbar. The query designer does a very bad job. It is almost useless because it can only produce baby-SQL. Within a weekend you learn much more SQL than that tool will ever be able to handle. I can demonstrate lots of working queries that are messed up completely once you load them into the design view. I wanted some examples of this, with already created queries. Exactly the last link you gave me... https://forum.openoffice.org/en/forum/viewtopic.php?f=83t=26328 On the linked forum you find dozends of example files with all kinds of calculations. However, I need a bit more: I would need help to understand these functions: *STDDEV_POP, STDDEV_SAMP, VAR_SAMP, VAR_POP, Collect, Fusion, Intersection* STDEV is the standard deviation, VAR stands for VARIATION, POP for a full population, STDDEV for a sample, I don't know about Collect, Fusion and Intersection. You might find them in SQL tutorials. -- To unsubscribe e-mail to: users+unsubscr...@global.libreoffice.org Problems? http://www.libreoffice.org/get-help/mailing-lists/how-to-unsubscribe/ Posting guidelines + more: http://wiki.documentfoundation.org/Netiquette List archive: http://listarchives.libreoffice.org/global/users/ All messages sent to this list will be publicly archived and cannot be deleted

I wanted some examples of this, with already created queries. Exactly the last link you gave me... https://forum.openoffice.org/en/forum/viewtopic.php?f=83t=26328 Is very useful, because it has queries, created with several functions. What I am looking for is exactly, that. However, I need a bit more: I would need help to understand these functions: *STDDEV_POP, STDDEV_SAMP, VAR_SAMP, VAR_POP, Collect, Fusion, Intersection* Those functions are like a mistery. I don't know where may I found information about what every one of them do exactly. Could you give me an .odb file with some queries, showing examples for these functions?
