Question

let’s say I have 10 tables and I need to write a simple LOG entry that states how many records each tables has.

Something like

Declare @msg Varchar(MAX)
Set @msg = 'Process Succeeded; Table1 has xx record, Table2 has zz records, Table3 has ww records ...'

Insert INTO LOG (msg) VALUES (@msg)

Answer 1

Or roll it up into:

 declare @Summary as VarChar(256)
 select @Summary =
   'Foo: ' + Cast( ( select Count(42) from Foo ) as VarChar(10) ) +
   ', Bar: ' + Cast( ( select Count(42) from Bar) as VarChar(10) )
 select @Summary
