if you have to deal with datawarehouses you need to implement dimension tables. A dimension could be the time dimension - a table of month Id&#8217;s for example&#160;to aggregate data per month. How to generate&#160; such month id&#8217;s (YYYYMM)?
Simply use the model clause - some Oracle 10g spreadsheet functionality and generate a bunch of [...]]]></description>

some aspects i need to remember in future installation i want to record here. SuSE Linux 10.1&#160;is different from the SLES/OpenSuSE&#160; Installations. Libraries, &#160;Development Tools, &#8230; are missing.

		<description><![CDATA[hi,
everybody tells you to use bind variables (reduced parses) and that&#8217;s ok. But in some circumstances you get a lot of problems with it. Using bind variables with the LIKE operator could cause horrible performance even you index that column and you do not use a &#8216;%&#8217; at the start of the searched string.

Once an Oracle Block is read from the disk it gets a place in the buffer cache. How long the block remains cached depends on following parameters.

if&#160;it&#8217;s an index block - they are stronger bound to the DEFAULT cache then table blocks resulting in&#160;a longer period&#160;of cache life cycle.
