The PLS_INTEGER datatype is specific to PL/SQL. It represents signed 32 bits integers that range from -2,147,483,648 to 2,147,483,647 . Because PLS_INTEGER datatype uses hardware arithmetic, they are faster than NUMBER operations, which uses software arithmetic.
What is the use of PLS_INTEGER?
PLS_INTEGER is a PL/SQL data type used for storing signed integers. PLS_INTEGER is defined in the STANDARD package as a subtype (or rather a synonym) of BINARY_INTEGER. Variables declared as PLS_INTEGER can be assigned values between -2**31 to 2**31-1 (-2,147,483,648 to 2,147,483,647).
What is the difference between PLS_INTEGER and BINARY_INTEGER?
PLS_INTEGER operations use machine arithmetic, so they are generally faster than NUMBER and INTEGER operations. Also, prior to Oracle Database 10g, they are faster than BINARY_INTEGER. In Oracle Database 10g, however, BINARY_INTEGER and PLS_INTEGER are now identical and can be used interchangeably.
What is Boolean in Plsql?
PL/SQL Boolean is the scalar datatype present in PL/ SQL which can store the logical values which can be either TRUE or FALSE. Many systems consider 1 value as the TRUE and 0 value as FALSE. … When Boolean datatype is assigned to the variable then it can either store true or false values in it.
Can PLS_INTEGER be null?
Positive: This type uses the non-negative, non-zero values of the PLS_INTEGER range. i.e., 1 to +2,147,483,647 and Null values.
What is difference between Pls_integer and INTEGER?
Answer: For integer values, the PLS_INTEGER type gives better performance and requires less storage space than either INTEGER or NUMBER types. … It is a good practice to use PLS_INTEGER versus NUMBER. The PLS_INTEGER data Type was introduced in PL/SQL version 2.2 and has a range of -2147483647 to 2147483647.
What is BINARY_INTEGER in PL SQL?
BINARY_INTEGER is a PL/SQL data type used for storing signed integers. BINARY_INTEGER is defined in the STANDARD package as a subtype of INTEGER. Variables declared as BINARY_INTEGER can be assigned values between -2**31 to 2**31-1 (-2,147,483,648 to 2,147,483,647).
What is the significance of symbol in PL SQL?
The range operator(..) is used as a shorthand way to set up arrays. When used with arrays, the range operator simplifies the process of creating arrays with contiguous sequences of numbers and letters.
What is index by Binary_integer in Oracle?
The first type of collection is known as index-by tables. … As the name implies, the collection is indexed using BINARY_INTEGER values, which do not need to be consecutive. The collection is extended by assigning values to an element using an index value that does not currently exist.
What are binary integer variables?
A binary integer variable—also called a 0/1 variable—is a special case of an integer variable that is required to be either zero or one. It’s often used as a switch to model Yes/No decisions.
Can we use BOOLEAN in PL SQL?
The Boolean data type in PL/SQL allows us to store True, False and Null values which help us in processing the logical states of a program unit. This data type is only available in PL/SQL and not in SQL, thus using Boolean values in an SQL statement has always been impossible until Oracle version 12cR1.
How do you call a BOOLEAN function in PL SQL?
create or replace function compairenumber(num1 in number,num2 in number) return boolean is begin if num1 < num2 then return true; else return false; end if; end; when i’m giving query select compairenumber(5,10) from dual its not returning true or false.
What is subtype in PL SQL?
A subtype is a definition of a type based on a built-in type. Subtypes provide a layer of abstraction between variables and parameters and the data types that they use. This layer allows you to concentrate any changes to the data types in one location.
What are the data types available in PL SQL?

How do you check if a number is even or odd in PL SQL?
PL/SQL Program to Check Number is Odd or Even
- n number:=&n;
- if mod(n,2)=0.
- dbms_output.put_line(‘number is even’);
- dbms_output.put_line(‘number is odd’);
What data types are available in Oracle?
