SQRT Function

The SQRT function returns the positive square root of its argument, which must be a non-negative numeric expression.

The following example returns the square root of 9 for each row of the angles table:

SELECT SQRT(9) FROM angles;

The SQRT function is equivalent to ROOT(x), where 2 is the default value of the second argument to the ROOT function, specifying the index.
