Row Count on all table

2	What is the best way to see how many row on each table, instead of using count()? rowcount asked 20 Feb '14, 15:43 pLee 215●11●12●20 accept rate: 0% flat view

One Answer:

If approximate numbers are sufficient, you can query the system catalog (row numbers are updated on each checkpoint):

select table_name, count from systab order by table_name

You could also add a "Checkpoint;" command just prior to Volker's select to force more up-to-date counts.
