I am running a basic install of MySQL 5.0 with "strict mode" turned on I
would like to use RPAD however at times a NULL var will be sent to the
function. My goal is to have a function that will convert the NULL to a
blank string to get the result of EXAMPLE3 if a NULL is returned.
EXAMPLE 1
mysql> select rpad(null,5,'1');
+------------------+
| rpad(null,5,'1') |
+------------------+
| NULL |
+------------------+
1 row in set (0.00 sec)
EXAMPLE 2
mysql> select rpad('0',5,'1');
+-----------------+
| rpad('0',5,'1') |
+-----------------+
| 01111 |
+-----------------+
1 row in set (0.00 sec)
mysql>
EXAMPLE 3
mysql> select rpad('',5,'1');
+----------------+
| rpad('',5,'1') |
+----------------+
| 11111 |
+----------------+
1 row in set (0.02 sec)
Is there a function I can use to convert the null string to a blank string
before it is sent to RPAD in a basic installation of MySQL or will I need
to create a function?
Wishing you the best you know you deserve,
