In the above snippet, the left operand is not equal to the right one so, it retrieves a boolean “true”. ![]() The following example considers a simple expression to show the usage of the Postgres NOT EQUAL “!=” operator: SELECT 200 + 300 != 400 As result For instance, the below syntax shows the syntax of the NOT EQUAL “!=” operator with the WHERE clause: SELECT column_listĪlternatively, the “” operator can be employed to commit the same functionality.Įxample 1: Using Not Equal Operator “!=” With Integers In Postgres, the comparison operators are most often used in the WHERE Clause of any statement. The operands must be valid (i.e., both operands must have implicitly convertible data types). For instance, the below syntax shows the basic syntax of the NOT EQUAL operator: SELECT operand_1 != operand_2 Postgres Not Equal to (!=) Operator compares the left operand with the right operand and retrieves true if the given operands are not equal, and false if the operand values are equal. ![]() How to Use the NOT EQUAL Operator in Postgres?
