“column not allowed here” error in INSERT statement

Question

I created this table called LOCATION by doing this:

CREATE TABLE LOCATION(
POSTCODE VARCHAR(10) PRIMARY KEY,
STREET_NAME VARCHAR(20),
CITY VARCHAR(20));
         


        

Answer 1

Like Scaffman said - You are missing quotes. Always when you are passing a value to varchar2 use quotes

INSERT INTO LOCATION VALUES('PQ95VM','HAPPY_STREET','FRANCE');

So one (') starts the string and the second (') closes it.

But if you want to add a quote symbol into a string for example:

My father told me: 'you have to be brave, son'.

You have to use a triple quote symbol like:

'My father told me: ''you have to be brave, son''.'

*adding quote method can vary on different db engines

Answer 2

You're missing quotes around the first value, it should be

INSERT INTO LOCATION VALUES('PQ95VM', 'HAPPY_STREET', 'FRANCE');

Incidentally, you'd be well-advised to specify the column names explicitly in the INSERT, for reasons of readability, maintainability and robustness, i.e.

INSERT INTO LOCATION (POSTCODE, STREET_NAME, CITY) VALUES ('PQ95VM', 'HAPPY_STREET', 'FRANCE');
