带有选择计数值的concat字符串-MySQL

Question

I want to add string with selected count value from table.

SELECT 
CONCAT(COUNT(*),' ', if(COUNT(*) > 1, 'rows','row')) AS NoOfRows
FROM myTable;

Output :

NoOfRows
BLOB

Expected :

NoOfRows
10 rows

What am I doing wrong?

Answer 1

Maybe you have to use cast function.

select
    concat(cast(count(*) as char(10)), ' ', if(count(*) > 1, 'rows','row')) as NoOfRows
from myTable;
