MySQL combine two columns into one column

This is the only solution that would work for me, when I required a space in between the columns being merged.

select concat(concat(column1,' '), column2)

Try this, it works for me

select (column1 || ' '|| column2) from table;

It's work for me

SELECT CONCAT(column1, ' ' ,column2) AS newColumn;

My guess is that you are using MySQL where the + operator does addition, along with silent conversion of the values to numbers. If a value does not start with a digit, then the converted value is 0.

So try this:

select concat(column1, column2)

Two ways to add a space:

select concat(column1, ' ', column2)
select concat_ws(' ', column1, column2)
