I created this table called LOCATION
by doing this:
CREATE TABLE LOCATION(
POSTCODE VARCHAR(10) PRIMARY KEY,
STREET_NAME VARCHAR(20),
CITY VARCHAR(20));
and when I try to add some date within the table it doesn’t work saying there is an error
INSERT INTO LOCATION VALUES(PQ95VM,'HAPPY_STREET','FRANCE');
error is saying
column not allowed here

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');

Some time, While executing insert query, we are facing:
Column not allowed here
error. Because of quote might missing in the string parameters. Add quote in the string params and try to execute.
Try this:
INSERT INTO LOCATION VALUES('PQ95VM','HAPPY_STREET','FRANCE');
or
INSERT INTO LOCATION (ID, FIRST_NAME, LAST_NAME) VALUES('PQ95VM','HAPPY_STREET','FRANCE');

INSERT INTO LOCATION VALUES(PQ95VM,'HAPPY_STREET','FRANCE');
the above mentioned code is not correct because your first parameter POSTCODE is of type VARCHAR(10). you should have used ' '.
try INSERT INTO LOCATION VALUES('PQ95VM','HAPPY_STREET','FRANCE');

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

Convert double quotes (» «) to single quotes (‘ ‘)
Example
If you have something like this:
INSERT INTO clients (id, email, country)
VALUES (1, "john@gmail.com", "USA");
Convert it to this:
INSERT INTO clients (id, email, country)
VALUES (1, 'john@gmail.com', 'USA');

I made the error of using the wrong quotation marks. I used double quotes as string delimiters in my value list instead of single quotes. Double quotes in Oracle are used as delimiters in column identifiers unlike in MySQL where they are used to enclose string literals.
INSERT INTO MYUSERS VALUES( 'Name', "Surname"); // Wrong
INSERT INTO MYUSERS VALUES( 'Name', 'Surname'); // Correct, Surname must be in single quotes

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.

This error creeps in if we make some spelling mistake in entering the variable name.
Like in stored proc, I have the variable name x and in my insert statement I am using
insert into tablename values(y);
It will throw an error column not allowed here.

Scanner sc = new Scanner(System.in);
String name = sc.nextLine();
String surname = sc.nextLine();
Statement statement = connection.createStatement();
String query = "INSERT INTO STUDENT VALUES("+'"name"'+","+'"surname"'+")";
statement.executeQuery();
Do not miss to add ‘»—-«‘ when concat the string.

Try using varchar2 instead of varchar and use this :
INSERT INTO LOCATION VALUES('PQ95VM','HAPPY_STREET','FRANCE');
answered Sep 13, 2020 at 7:30
While inserting the data, we have to used character string delimiter (' '). And, you missed it (' ') while inserting values which is the reason of your error message. The correction of code is given below:
INSERT INTO LOCATION VALUES(PQ95VM,'HAPPY_STREET','FRANCE');

I too got the same error while working with insert command. When i replaced double quotes with single quotes it worked fine
answered Apr 7, 2021 at 6:57
If PQ95VM is supposed to be a literal string, then use 'PQ95VM'. If it is a variable, make sure it is declared.

ORA-00984: column not allowed here error that occurs when you try to use a column that is not allowed in a particular area of the sql. The ORA 00984: column not allowed here error occurs when a column is not allowed in the VALUES clause of the insert query, the column name is used in VALUES clause or missing quotes in the insert statement. The VALUES clause should contain values that will be stored in the table. If the column name is specified in the VALUES clause, the insert statement will fail to save the values. The ORA-00984: column not allowed here error occurs if double quotes are used in character or date value. In varchar or date data type values, single quotes should be used.
In the Oracle insert statement, the character string or date value should be enclosed by single quotes. If single quotes are not used in the values or double quotes are used, the insert statement will fail to recognize the string or date value. If the quotations in the insert statement VALUES clause are missing, it will be treated as a column name. The insert statement was unable to store the values in the table. The error ORA-00984: column not allowed here will be thrown.
When this ORA-00984 error occurs
The error ORA-00984: column not allowed here will be thrown if the single quotation in the string value or date value is missing in the VALUES clause of the insert statement. If the double quotation mark is used in the insert statement for a string or date value, the error ORA-00984: column not allowed here will occur.

Error report -
SQL Error: ORA-00984: column not allowed here
00984. 00000 - "column not allowed here"Root Cause
In oracle, a string value or a date value is created by enclosed with a single quotation. If a single quotation is missed in a string value and a date value or enclosed with double quotation, oracle will not recognise the string and date. It will be interpreted as a column name. Because a column name is not permitted in the insert statement’s VALUES clause, Oracle will thrown this error
Solution 1
If the VALUES clause of the insert statement has a column name, delete it and replace it with a value. The insert statement was unable to save a column name. If you pass the value of a column in the insert statement, the error ORA-00984: column not allowed here will be resolved.
Problem
CREATE TABLE EMP(
id int,
name VARCHAR2(100)
)
insert into emp values (1, name);
Error report -
SQL Error: ORA-00984: column not allowed here
00984. 00000 - "column not allowed here"Solution
insert into emp values (1, 'kim');
1 row inserted.Solution 2
If a single quote is missing in the insert statement’s VALUES clause for a string or date value, the insert statement will fail to recognize the string or date value. The insert statement will fail to store the value in the table. The ORA-00984: column not allowed here will be thrown. The error will be fixed if a single quote mark is placed around a string or date value.
Problem
insert into emp values (1, kim);
Error report -
SQL Error: ORA-00984: column not allowed here
00984. 00000 - "column not allowed here"Solution
insert into emp values (1, 'kim');
1 row inserted.Solution 3
In Oracle, the string value or date value should be surrounded by a single quotation. If the string value or date value is surrounded by double quotation marks, Oracle will not recognize it as a string value or date value. The error message ORA-00984: column not allowed here will be shown. The issue will be fixed if the double quotation in the string value or date value is replaced with a single quotation.
Problem
insert into emp values (1, "kim");

Learn the cause and how to resolve the ORA-00984 error message in Oracle.
Description
When you encounter an ORA-00984 error, the following error message will appear:
- ORA-00984: column not allowed here
Cause
You tried to execute a SQL statement that included a column name where it was not permitted.
Resolution
The option(s) to resolve this Oracle error are:
Option #1
This error most commonly occurs when you try to include a column name in the VALUES clause of a INSERT statement.
For example, if you had tried to use the column named customers in an INSERT statement as follows:
INSERT INTO suppliers (supplier_id, supplier_name) VALUES (1, customer_name);
You would receive the following error message:
You could correct the INSERT statement by including a character value, instead of the column name as follows:
INSERT INTO suppliers (supplier_id, supplier_name) VALUES (1, 'IBM');
Or if you needed to include a column name, you could rewrite the INSERT statement with a sub-select as follows:
INSERT INTO supplier (supplier_id, supplier_name) SELECT account_no, customer_name FROM customers WHERE city = 'Newark';
ORA-00984: Column Not Allowed
The majority of Oracle mistakes are the result of simple mix-ups. Whether it is through errors deriving from copying and pasting across programs, mistaking program functions or just flat-out getting distracted during your work, programming an Oracle database can lead to user errors that are relatively easy to create. Often, these mistakes can be tough to spot at first, but, once the user is aware of them, they typically seem like a simple oversight. Thankfully, the user-friendly nature of Oracle means that problems like an ORA-00984 message are fairly easy to remedy.
The Problem
The ORA-00984 is an error resulting from a column not being allowed in a particular area of the program. It occurs when a user attempts to issue a SQL statement that includes a column name where it is not permitted. This can most often happen in reference to a false insertion in a VALUES clause of an INSERT statement.
For a refresher, let us go over the syntax that is most commonly used with INSERT statements. For a VALUES keyword, you will often work with this format:
INSERT INTO table
(column1, column2, … column_n )
VALUES
(expression1, expression2, … expression_n );
And for a SELECT statement, you will usually see the following:
INSERT INTO table
(column1, column2, … column_n )
SELECT expression1, expression2, … expression_n
FROM source_table
WHERE conditions;
So, as you can see from above, by accidentally inserting a column name under the VALUES section as opposed to the INSERT INTO table section in the first format, the ORA-00984 error could quite possibly be triggered.
Now that we know the source of this error, let us look at some strategies to amend the issue.
The Solution
To correct the error, the user can take a couple of approaches. First, the user could correct the INSERT statement by including a character value (instead of the column name). Additionally, if the user needs to include a column name, they could rewrite the INSERT statement with a sub-select.
A quick side note: On occasion, you will not be able to find information about the error in the alert.log file. This runs contrary to a lot of Oracle instinct where you can check this file for the source of the Oracle errors once you receive them. Instead, if there is no information about the error in this location, open the DML error logging. You can audit Oracle with additional AUDIT syntax by using the DDL audit and the LogMiner audits. DDL audit triggers allow an administrator to automatically track all changes to the database. This includes changes to tables, indices, and constraints, which can be quite useful in your search for the error source.
The Example
Let us now turn to an example to see how a solution can be successfully implemented. Suppose you tried to use the column named “clients” in an INSERT statement, much like the following:
INSERT INTO employers
(business_id, business_name)
VALUES
(7, client_name);
You would subsequently receive an error message, “ORA-00984: column not allowed here”. By taking the first approach, the following will change with the character value inclusion:
INSERT INTO employers
(business_id, business_name)
VALUES
(7, ‘Mohammad’);
Alternatively, if you took the approach of rewriting the INSERT statement with a sub-select, here is how it would look:
INSERT INTO employers
(business_id, business_name)
SELECT employer_no, client_name
FROM clients
WHERE city = ‘Syracuse’;
Both of these changes can correct the ORA-00984 error and allow your system to return to a fully-functioning state.
Looking Forward
Staying aware of how columns and values interact within your database is key to preventing errors like ORA-00984. It can be easy to get caught up in the tunnel vision that sometimes accompanies coding; keeping a clear eye can give you a cautious perspective that could save hours of frustration. Working with a dedicated Oracle consulting firm can also provide you with the proper mindset that is necessary to avoid these mistakes in your Oracle database.
