![]() ![]() ![]() The value must be the integer value else it will end up with throwing the error. The variable defined with the integer data type can only store the integer value. It mainly provides two distinct types of numeric data types. Given below are different PostgreSQL Types: If the user tries to feed the value of different data types in that variable, it will lead to an error. For instance, if any variable is supposed to store the integer values only, then in all the cases, it will store the integer value only. In simple terms, the variable that is assigned with one of the data types can store the value of that data type only. The data type may be defined as a kind of data. Since data is a critical part of any system, a platform must exist to aid in processing and managing the data. This post presented a detailed guide on how to use integer data types in Postgres via examples.Hadoop, Data Science, Statistics & othersĮvery application that works with data requires a database to store all the data-related to the application. Each data type stores a different range of values and has different storage requirements. These data types assist us in storing and manipulating whole numbers. PostgreSQL provides several integer data types that help us fulfill our needs, such as INTEGER, SMALLINT, and BIGINT. The maximum range of the SMALLINT type is +32,767 however, we tried to store “500000”, which causes the “smallint out of range” error. If we insert an out-of-range value, then we will encounter the following error: INSERT INTO example_tab(exp_small, exp_int, exp_big) Output authenticates the working of the integer data types. To fetch the “example_tab” data, you must execute the “SELECT *” command: The output shows that three records have been inserted into the “example_tab” tab. Execute the below query to insert integer data into the “example_tab” table: INSERT INTO example_tab(exp_small, exp_int, exp_big) The output snippet indicates that a table has been created with the integer data types. Let’s learn how we can use integer data types in Postgres: CREATE TABLE example_tab ( So, use the BIGINT data type when you have a proper reason to use it.Įxample: How to Create/Define a Table With INTEGER Data Types in PostgreSQL? Note: The BIGINT data type consumes too much storage, which decreases the database efficiency. Trying to store an out-of-the-specified range will throw an error. The storage size of the BIGINT is eight bytes. The following points will explain the working of the Postgres BIGINT data type: The minimum range of the INT type is -2,147,483,648. The storage size of the INTEGER is four bytes. The below-listed points present the working of the Postgres INTEGER data type: The minimum range of the SMALLINT type is -32,768. The storage size of the SMALLINT is two bytes. ![]() The below-listed points demonstrate the working of the Postgres SMALLINT data type: This section will explain the three primary data types to store the integer data in Postgres. This blog post will explain various integer data types via practical examples. You can store integer data types in PostgreSQL no matter what your requirements are. ![]()
