![]() Let’s take an example where you have a table called ‘customers_data’ with columns name and country. stringValue1, stringValue2, stringValue3, ….: These are the multiple string values that are combined together to form a single string value.CONCAT(): It is the concat() function itself which accepts the multiple string data.CONCAT(stringValue1, stringValue2, stringValue3. ![]() If any of the provided input values is NULL, then while concatenating the strings it ignores the NULL values. The concat() function is called the VARIADIC function which means it also accepts the array data. You can provide different types of string data such as varchar, char, and text. In general, you pass the list of elements to the concat() function and this element should be a convertible string. PostgreSQL has a concat() function which takes multiple strings and combines them into single-string values. How to Concat in Postgres using CONCAT() function The value of columns first_name and last_name are concatenated using the pipe || operator as you can see in the above query. Look at the output which shows the customer’s first and last name as a single value or full name in a new column ‘customer_name’. Let’s check with an example, suppose you have table ‘orders’ with columns first_name, last_name, and order_date. Instead of string, you can also use the columns whose values you want to combine together. In the above syntax, you can use the pipe || operator to combine multiple strings (string1, string2, and so on) into a single string value. This operator is also called a string concatenation operator. The pipe || operator of Postgres combines multiple or more than one string/text into a single value. How to Concat in Postgres using Pipe Operator Let’s see some example that uses different functions for the concatenation of the string or text values. There are several ways to concat the string or text in PostgreSQL and for that, PostgreSQL provides different functions.įrom a database scenario, concatenation can be helpful in situations where you want to combine the first or last name of the employee which exists in different columns of the table.Īlso, you can represent the information in a more meaningful way by concatenating the different values into a single value. In terms of a database, concatenate means joining two things (such as string or text) together to form a single thing( string or text). The full name of the concat is concatenate, the concatenate means add something together.
