How to concat datatypes like integers(integer with integer) & varchar(varchar with varchar) in mysql?
Solution 1:
Use CONCAT
http://dev.mysql.com/doc/refman/5.1/en/string-functions.html#function_concat
SELECT CONCAT(1, 2);
-- "12"
SELECT CONCAT('foo', 'bar');
-- "foobar"
SELECT CONCAT(1, 'bar');
-- "1bar"
Solution 2:
if the arguments include any binary strings, the result is a binary string. A numeric argument is converted to its equivalent binary string form; if you want to avoid that, you can use an explicit type cast, as in this example:
SELECT CONCAT(CAST(int_col AS CHAR), char_col);
