![]() Output proves that concatenating a NULL value with strings using the "||" operator returns null. Let’s consider the below snippet to see how the “||” operator deals with the NULL values: SELECT 'PostgreSQL' || NULL || 'Databases' AS output ![]() The output shows that the “||” operator successfully concatenated the given strings.Įxample 2: Concatenate Two Strings and a NULL Value Using || Operator For this, two strings “PostgreSQL” and “Databases” will be concatenated through the “||” operator: SELECT 'PostgreSQL' || ' ' || 'Databases' AS result In PostgreSQL, two strings can be concatenated with the help of the “||” operator. In the above syntax, str_1, str_2, str_n represents the strings, words, characters to be concatenated.Įxample 1: Concatenate Two Strings Using || Operator in Postgres The syntax to concatenate two or more strings using the “CONCAT()” function will be as follows: SELECT CONCAT('str_1', 'str_2', 'str_n') Here, str_1, str_2, str_n are the strings to be concatenated. Let's start with the syntax of the “||” operator: 'str_1' || 'str_2 ' || 'str_n' In this section, we will show you how to concatenate strings using the “||” operator and the CONCAT() function.
