I need help. I'm relatively new to SQL coding.

I need to create View of:
The number of meters read in the current month by each of the meter readers (this view should be able to be used at any time without having to be changed to accommodate the date).

And I have this code

```
CREATE VIEW ViewA AS
SELECT SUM(meter) FROM reading
WHERE MONTH(columnName) = MONTH(CURRENT_DATE());

```

But the error says:
Error starting at line : 1 in command -
CREATE VIEW ViewA AS
SELECT SUM(meter) FROM reading
WHERE MONTH = MONTH(CURRENT\_DATE())
Error report -
ORA-00907: missing right parenthesis
00907. 00000 - "missing right parenthesis"
