“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

What you missed is " " in postcode because it is a varchar.

There are two ways of inserting.

When you created a table Table created. and you add a row just after creating it, you can use the following method.

INSERT INTO table_name
VALUES (value1,value2,value3,...);

1 row created.

You've added so many tables, or it is saved and you are reopening it, you need to mention the table's column name too or else it will display the same error.

ERROR at line 2:
ORA-00984: column not allowed here


INSERT INTO table_name (column1,column2,column3,...)
VALUES (value1,value2,value3,...);

1 row created.
