The SQL statement requires two sets of values equal in number. This error occurs when the second set contains more items than the first set. For example, the subquery in a WHERE or HAVING clause may return too many columns, or a VALUES or SELECT clause may return more columns than are listed in the INSERT.

Problem Note 57778: An "ORA-00913: too many values.." error might occur after opening the Pack Optimization Products view. This error is likely to occur when you have a high volume of size sets in your system. The workaround for this issue is to reduce the number of size sets in your system.
For example, the subquery in a WHERE or HAVING clause may return too many columns, or a VALUES or SELECT clause may return more columns than are listed in the INSERT. Action: Check the number of items in each set and change the SQL statement to make them equal.
Cause: This error occurs when a SQL statement requires two sets of values equal in number, but the second set contains fewer items than the first set. This can occur in a WHERE or HAVING clause in which a nested SELECT returns too few columns as in: WHERE (A,B) IN (SELECT C FROM ...)
What causes an ORA-00913 error? The SQL statement requires two sets of values equal in number. This error occurs when the second set contains more items than the first set.
Let's look at an example that shows how to add a column in an Oracle table using the ALTER TABLE statement. For example: ALTER TABLE customers ADD customer_name varchar2(45); This Oracle ALTER TABLE example will add a column called customer_name to the customers table that is a data type of varchar2(45).
An Oracle Identity column can be reset by simply changing its start value with an alter table...modify statement. Given that identity column internally uses a sequence, why is it not possible to do the same with a sequence i.e. change its start value to a specific number with a single alter statement?
ORA-00947 not enough values. Cause: This error occurs when a SQL statement requires two sets of values equal in number, but the second set contains fewer items than the first set. This can occur in a WHERE or HAVING clause in which a nested SELECT returns too few columns as in: WHERE (A,B) IN (SELECT C FROM ...)
You just need to check the number of columns and its type in both the tables ie the tables that are involved in the sql. In my case, the insert statement was missing one column, and so in select , I had one additional value. Adding the missing column in the insert statement fixed the error for me.
The function ISNULL() returns all records with 'NULL' values and records having Empty value (”) or Spaces (' ') in the specified column. Expression can be a column name and replacement is the string value which will replace the column value.
For debugging, use the -d option while running the oracle-compute command. The -d option prints out all the HTTP traffic, which facilitates the user in debugging error messages. Scripting on this page enhances content navigation, but does not change the content in any way.
Possible causes of error 913 are: Accessing a stored procedure or view that refers to a table in a database that has been dropped. Accessing a stored procedure or view that refers to a table in a database that has been dropped and re-created.
The Oracle INSERT ALL statement is used to insert multiple rows with a single INSERT statement. You can insert the rows into one table or multiple tables by using only one SQL command.
To MODIFY a column in an existing table, the Oracle ALTER TABLE syntax is: ALTER TABLE customers MODIFY column_name column_type; ALTER TABLE MODIFY allows modifying the constraints such as primary key, column size, type, its default value, length, nullability, etc. Here is an example of modifying the first_name column.
There are a few basic options. You can modify the SQL so that no duplicate values are created, thus no errors are triggered. If you do not wish to do this, you can also simply drop the table constraint altogether. This would only be recommended if the constraint is unnecessary for the foundation of your table.
