The ‘how’ of teaching also gets a great deal of space – how to structure a lesson, manage classes, assess for learning for learning and so on.

In teacher education programmes – and in continuing professional development – a lot of time is devoted to the ‘what’ of teaching – what areas we should we cover, what resources do we need and so on. how to cite this piece Linked piece: the key activities of teachingĪ definition for starters: Teaching is the process of attending to people’s needs, experiences and feelings, and intervening so that they learn particular things, and go beyond the given.structuring interventions and making use of different methods.He sets this within a discussion of pedagogy and didactics and demonstrates that we need to unhook consideration of the process of teaching from the role of ‘teacher’ in schools.

While both sys.partitions and sys.dm_db_partition_stats should both have correct row counts, I'd put more trust in the PARTITIONCOUNTS internal table. The on-prem version of sys.dm_db_partition_stats gets its row counts differently, from the internal table, PARTITIONCOUNTS: CREATE VIEW sys.dm_db_partition_stats ASĬROSS APPLY OpenRowSet(TABLE PARTITIONCOUNTS, i.object_id, i.index_id, i.rowset) c LEFT JOIN sys.syspalvalues cl ON cl.class = 'CMPL' AND cl.value = cmprlevel The definition of sys.partitions is: CREATE VIEW sys.partitions ASįROM sys.sysrowsets rs OUTER APPLY OpenRowset(TABLE ALUCOUNT, rs.rowsetid, 0, 0) ct In the on-prem version of SQL Server, sys.partitions gets its row counts from the internal table ALUCOUNT or sys.sysrowsets, if ALUCOUNT.rows is NULL.

Note, I removed the CONVERT(date.) functionality so this code is compatible with all partition schemes, not just those with date range values. INNER JOIN sys.dm_db_partition_stats ddps ON t.object_id = ddps.object_idįor Azure SQL Data Warehouse, you'll need to use sys.dm_pdw_nodes_db_partition_stats instead of sys.dm_db_partition_stats, even though they contain the same details.

Join sys.schemas sc on sc.schema_id = t.schema_id Sys.partitions query: SELECT convert(date, convert(varchar,rv.)) as partitionDate, p.rows as syspartitions_RowCount Statistics are updated daily after each data load. The table has a clustered columnstore index and statistics have been created on almost all of the columns. I've noticed that this is returning the same row count for all partitions, regardless of the actual content (even for empty partitions).
Querying sys.partitions can return an approximate row count for a table.
