DROP FUNCTION IF EXISTS format_path;
DELIMITER $$
CREATE DEFINER='root'@'localhost' FUNCTION format_path (
path VARCHAR(260)
)
RETURNS VARCHAR(260) CHARSET UTF8
COMMENT '
Description
-----------
Takes a raw path value, and strips out the datadir or tmpdir
replacing with @@datadir and @@tmpdir respectively.
Also normalizes the paths across operating systems, so backslashes
on Windows are converted to forward slashes
Parameters
-----------
path (VARCHAR(260)):
The raw file path value to format.
Returns
-----------
VARCHAR(260) CHARSET UTF8
Example
-----------
mysql> select @@datadir;
+-----------------------------------------------+
| @@datadir |
+-----------------------------------------------+
| /Users/mark/sandboxes/SmallTree/AMaster/data/ |
+-----------------------------------------------+
1 row in set (0.06 sec)
mysql> select format_path(\'/Users/mark/sandboxes/SmallTree/AMaster/data/mysql/proc.MYD\') AS path;
+--------------------------+
| path |
+--------------------------+
| @@datadir/mysql/proc.MYD |
+--------------------------+
