If you’re trying to run a multi-line query in SQLcl or SQL*Plus, and you keep getting an error such as “Unknown Command”, but running it in SQL Developer causes no such error, maybe this post will help.
By default, SQLcl and SQL*Plus don’t allow blank lines in SQL statements. However, you can change this with the SET SQLBLANKLINES command.
In Oracle, the SINH() function returns the hyperbolic sine of its argument.
In Oracle, the SIN() function returns the sine of its argument, where the argument is an angle expressed in radians.
In Oracle, the POWER() function returns its first argument raised to the power of its second argument.
In Oracle, the REMAINDER() function returns the remainder of its first argument divided by its second.
It’s similar to the MOD() function, except that it uses ROUND() in its calculation, whereas MOD() uses FLOOR() in its calculation.
In Oracle, the MOD() function returns the modulo operation. In other words, it returns the remainder of its first argument divided by its second.
In Oracle, the EXP() function returns the value of e (the base of natural logarithms) raised to the power of the argument.
The number e, also known as Euler’s number, is a mathematical constant approximately equal to 2.71828.
Continue readingIn Oracle, the COSH() function returns the hyperbolic cosine of its argument.
In Oracle, the COS() function returns the cosine of its argument.
In Oracle, the ROUND(number) function returns a number rounded to a given number of decimal places.
By default, it rounds the number to zero decimal places, but you can provide an optional argument that specifies the number of decimal places to use.
Oracle also has a ROUND(date) syntax, which is used on dates. This article is solely about the ROUND(number) syntax, which is used on numbers.
