syspartitions

All databases

Description

syspartitions contains one row for each data partition and one row for each index partition.

For each database, syspartitions contains one row for:

If an index is local, the value for partitionid (data partition row) and data_partitionid (associated index row) are the same. If the index is not local, the value for data_partitionid (index row) is zero (0), and it does not equal that for partitionid (data partition row).

NoteThe syspartitions table in versions of Adaptive Server earlier than 15.0 has been renamed sysslices and made obsolete. With Adaptive Server version 15.0, syspartitions is completely redefined, and now supports data and index partitioning.
