How do you resolve a divide by zero error in Oracle?

We place the following logic using NULLIF function for eliminating SQL divide by zero error:

  1. Use NULLIF function in the denominator with second argument value zero.
  2. If the value of the first argument is also, zero, this function returns a null value.

How do you fix a divisor equal to zero?

This ORA-01476 errors are related with the expression attempted to divide by zero. To solve this error, don’t use to divide by ZERO value, Use another value instead of ZERO. Or you can use NULLIF function to solve this error.

What is Sqlcode and Sqlerrm in Oracle?

SQLCODE and SQLERRM are Oracle’s built-in error reporting functions in PL/SQL. When an error occurs in PL/SQL at runtime: SQLCODE returns the number of the last encountered error. SQLERRM returns the message associated with its error-number argument.

What are the two types of exceptions in Oracle?

There are three types of exceptions:

  • Predefined exceptions are error conditions that are defined by PL/SQL.
  • Non-predefined exceptions include any standard TimesTen errors.
  • User-defined exceptions are exceptions specific to your application.

What will you do to handle divide by zero in SQL query?

If you’d like to handle division by zero gracefully, you can use the NULLIF function. NULLIF takes two arguments: the expression of interest, and the value you want to override. If the first argument is equal to the second, then NULLIF returns NULL; otherwise, it returns the first argument.

How does decode work in SQL?

DECODE compares the expression to each search value one by one. If expression is equal to a search, then the corresponding result is returned by the Oracle Database. If a match is not found, then default is returned. If default is omitted, then Oracle returns null.

What is the difference between Pragma EXCEPTION_INIT and Raise_application_error?

EXCEPTION_INIT is helps to assign a error number to the exception and which can be raised using RAISE and can be handled in EXCEPTION block. RAISE_APPLICATION_ERROR is used to return a valid error message to the calling application like Java, .

What does Sqlerrm return?

The function SQLERRM returns the error message associated with its error-number argument. If the argument is omitted, it returns the error message associated with the current value of SQLCODE . SQLERRM with no argument is useful only in an exception handler.

What is Pragma Exception_init in Oracle?

The pragma EXCEPTION_INIT associates an exception name with an Oracle error number. You can intercept any ORA- error and write a specific handler for it instead of using the OTHERS handler.

What are the two types of exceptions in PL SQL?

PL/SQL – Exceptions

  • System-defined exceptions.
  • User-defined exceptions.
