sql - Use Group By for real or float column with specify precision -


how can specify precision column of real type (eg. 3 digits after decimal point) group by clause?

eg. 12.023006 equal 12.023007 3 digits precision after decimal point , should grouped group by.

a couple ways can achieve this, 1 of cast field appropriate precision:

select cast(somecol decimal(10,3)) sometable group cast(somecol decimal(10,3))

you use round function achieve this.
