Oracle/PLSQL: ORA-00913 Error

Error:

ORA-00913: too many values

Cause:

You tried to execute an SQL statement that required two sets of equal values, but you entered more items in the second set than was in the first set.

Action:

The options to resolve this Oracle error are:

This error often occurs when you are performing an INSERT statement and enter more values in the VALUES clause than the number of columns that you listed.

For example, if you executed the following INSERT statement:

INSERT INTO suppliers
(supplier_id, supplier_name)
VALUES
(1000, 'Microsoft', 'Bill Gates');

In this example, you've chosen to insert values into 2 columns (supplier_id and supplier_name), but you've entered 3 values (1000, Microsoft, and Bill Gates).

You need to modify your INSERT statement so there are the same number of columns as there are values. For example:

INSERT INTO suppliers
(supplier_id, supplier_name)
VALUES
(1000, 'Microsoft');

This error can also occur when your subquery in the WHERE clause returns too many columns.

For example, if you executed the following SQL statement:

SELECT * FROM suppliers

WHERE supplier_id > 5000

AND supplier_id IN (SELECT * FROM products

WHERE product_name LIKE 'H%);

In this example, the subquery returns all columns from the products table. You need to modify the subquery to return only one column as follows:

SELECT * FROM suppliers

WHERE supplier_id > 5000

AND supplier_id IN (SELECT product_id FROM products

WHERE product_name LIKE 'H%);
