APPENDIX C
VLDB Properties
C
VLDB properties (sometimes called VLDB settings) allow you to
customize the SQL which MicroStrategy generates. You can manipulate
things like SQL join types, SQL inserts, table creation properties, and so
on. Use the VLDB Properties Editor to change the defaults to alter the
syntax of a SQL statement and take advantage of unique, database-specific
optimizations.
Some of the qualities that make these properties valuable are:
• Optimization: Take advantage of database-specific settings to further
enhance the performance of queries.
• Flexibility: VLDB properties are available at multiple levels, so that the
SQL generated for one report, for example, may be manipulated
separately from the SQL generated from another, similar report.
• Complete database support: VLDB properties allow you to easily
incorporate and take advantage of new database platforms and
versions.
VLDB Hierarchy
VLDB properties can be set at various levels in the MicroStrategy
architecture. The following diagram shows the how VLDB properties set
for one object take precedence over those set for another:
