How your code responds to and deals with that error often spells the difference between a successful application and one that creates all sorts of problems for users as well as developers. This article explores the world of error management in PL/SQL: the different types of exceptions you may encounter; when, why, and

how exceptions are raised; how to define your own exceptions; how you can handle exceptions when they occur; and how you can report information about problems back to your users. Exception Overview There are three categories of exceptions in the world of PL/SQL: internally defined, predefined, and user-defined. An internally defined exception is one that is raised internally by an Oracle Database process; this kind of exception always has an error code but does not have a name unless it is assigned one by PL/SQL or your own code. An example of an internally defined exception is ORA-00060 (deadlock detected while waiting for resource). A predefined exception is an internally defined exception that is assigned a name by PL/SQL. Most predefined exceptions are defined in the STANDARD package (a package provided by Oracle Database that defines many common programming elements of the PL/SQL language) and are among the most commonly encountered exceptions. One example is ORA-00001, which is assigned the name DUP_VAL_ON_INDEX in P

What does the SQLERRM Function do? The SQLERRM function returns the error message associated with the most recently raised error exception. This function should only be used within the Exception Handling https://www.techonthenet.com/oracle/exceptions/sqlerrm.php section of your code. Syntax The syntax for the SQLERRM function in Oracle/PLSQL is: SQLERRM Parameters or Arguments There are no parameters or arguments for the SQLERRM function. Note See also the SQLCODE function. Example Since EXCEPTION HANDLING is usually written with the following syntax: EXCEPTION WHEN exception_name1 THEN [statements] WHEN exception_name2 THEN [statements] WHEN exception_name_n THEN [statements] WHEN OTHERS THEN [statements] END [procedure_name]; You could use the SQLERRM function to raise an error as follows: EXCEPTION WHEN OTHERS THEN raise_application_error(-20001,'An error was encountered - '||SQLCODE||' -ERROR- '||SQLERRM); END; Or you could log the error to a table using the SQLERRM function as follows: EXCEPTION WHEN OTHERS THEN err_code := SQLCODE; err_msg := SUBSTR(SQLERRM, 1, 200); INSERT INTO audit_table (error_number, error_message) VALUES (err_code, err_msg); END; NEXT: Declare Cursor Share this page: Advertisement Back to top Home | About Us | Contact Us | Testimonials | Donate While using this site, you agree to have

Description When you encounter an ORA-00913 error, the following error message will appear: ORA-00913: too many values Cause You tried to execute a SQL statement that required two sets of equal values, but you entered more items in the second set oracle sql sql than was in the first set. Resolution The option(s) to resolve this Oracle error are: Option #1 This error often occurs when you are performing a 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'); Option #2 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 supplie
