How is the concat_ws function used in MySQL?

In MySQL, the CONCAT_WS function is used to concatenate two or more strings together, separating them with a specified delimiter. Its syntax is as follows:

Combine strings with a specified separator.

In this case, the separator is a delimiter, and parameters like string1, string2 are the strings to be concatenated. It will join the strings together with the specified delimiter and return the result.

For example, if we run the following query:

Combine the strings ‘2022’, ’05’, and ’31’ with a hyphen in between.

The result will be:

May 31, 2022

Here, we concatenate the strings ‘2022’, ’05’, and ’31’ together using “-” as a delimiter.
