[mapserver-users] mapserver >= 5.6 and querys via php-mapscript

[Lime, Steve D (DNR)]

The concept changed in 5.6 to support improved query performance, especially for RDBMS data sources. It's been a bit of
a cluster though and interpretation of $result->shapeindex varies by 5.6.x version and driver. We'll get this straightened
out and simplified in 6.0. Addressing 5.6.3 only:


-          shapeindex should hold the global record index for a shape

-          tileindex should hold the result set record index for a shape (for RDBMS data sources, e.g. Oracle and PostGIS only)

There still may be inconsistencies with OGR-fronted RDBMS sources.

in the older ms versions I got with $result->shapeindex an absolute record
id for all data sources (postgis, OGR, shapefiles).
what ids were used before by default e.g. for postgis data?
why this concept has changed in the new version 5.6?
Thanx
