MySQL combine two columns into one column

Question

I\'m trying to find a way to combine two columns into one, but keep getting the value \'0\' in the column instead to the combination of the words.

These are what I\'

Answer 1

It's work for me

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

Answer 2

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)

Answer 3

convert(varchar, column_name1) + (varchar, column_name)

Answer 4

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)
