STDDEV returns sample standard deviation of expr, a set of numbers. You can use it as both an aggregate and analytic function. It differs from STDDEV_SAMP in that STDDEV returns zero when it has only 1 row of input data, whereas STDDEV_SAMP returns a null. Oracle calculates the standard ...
The STDDEV function can be used in the following versions of Oracle/PLSQL: Oracle 12c, Oracle 11g, Oracle 10g, Oracle 9i, Oracle 8i Example (as an Aggregate Function) Let's look at some Oracle STDDEV function examples and explore how to use the STDDEV function in Oracle/PLSQL. For examp...
