The concatenation of two or more numbers is the number formed by concatenating their numerals. For example, the concatenation of 1, 234, and 5678 is 12345678. The value of the result depends on the numeric base, which is typically understood from context.

Another way to implement Concat in SQL with the numerical value is to use the CAST operator. This operator converts the numerical data into the string format. Using the + (plus) operator will manipulate the numeric data into string concatenation. You must convert the numerical data into a string data type.

SQL Server CONCAT() Function ExampleGet your own SQL Server. Add two strings together: SELECT CONCAT('W3Schools', '.com'); Example. Add 3 strings together: SELECT CONCAT('SQL', ' is', ' fun!'); ... Example. Add strings together (separate each string with a space character): SELECT CONCAT('SQL', ' ', 'is', ' ', 'fun!');

Approach: The simplest approach to do this is: Convert both numbers to string. Concatenate both strings into one, as this is comparatively easy. Convert this concatenated string back to integer.

To concatenate a string and a number, such as an integer ( int ) or a floating point number ( float ), you first need to convert the number to a string using str() . Then, you can use the + or += operator to concatenate.

PostgreSQL allows us to concatenate a string with a number using a built-in “CONCAT()” function or a pipe operator “||”. The return type of the pipe concatenation operator || and CONCAT() function is “TEXT”. So, using these methods, you can concatenate multiple strings and numbers in Postgres.

JavaScript (+) sign concatenates instead of giving sum? The + sign concatenates because you haven't used parseInt(). The values from the textbox are string values, therefore you need to use parseInt() to parse the value.
