PostgreSQL Conditions

In this section, we are going to understand the different types of PostgreSQL Conditions, which are used to get more specific results to form a database. They are generally used with the WHERE clause.

Introduction of PostgreSQL Condition

In PostgreSQL, we have various types of conditions used to return more details output from the database. Usually, the Conditions with a clause act like a double layer filter.

Some of the most commonly used PostgreSQL conditions are as follows:

PostgreSQL AND Condition

The PostgreSQL AND condition are used to specify the data, if all the conditions separated by AND are TRUE. Or we can say that it is used with WHERE clause to get involved in those rows where both conditions are true.

PostgreSQL OR Condition

The PostgreSQL OR condition is used with WHERE clause to include rows where either condition is true and select unique data either from various columns in a table.

PostgreSQL AND & OR Condition

PostgreSQL AND & OR Condition, which is used, provides the advantages of AND & OR Condition both in just a single command. The PostgreSQL allows us to test several conditions with the help AND & OR operators.

PostgreSQL NOT Condition

The PostgreSQL NOT condition is used to get those rows where a condition is not true. And we can combine the NOT condition with the WHERE Clause.

PostgreSQL LIKE Condition

It is used to fetch data from a table where the defined condition satisfies the LIKE condition. And we can also say that the Like condition is used to perform pattern matching for identifying the exact outcome.

PostgreSQL IN Condition

The PostgreSQL IN condition is used to describe the several values in a WHERE clause. And it is a shorthand for various OR conditions. The PostgreSQL IN condition can be used with the SELECT, INSERT, UPDATE, and DELETE commands.

PostgreSQL BETWEEN Condition

The PostgreSQL Between condition is used to select values within a given range, and the values can be text, numbers, or dates. It can also be used with the WHERE clause to return data from a table between two defined conditions.
