Let's just say I've got an SQL database with 10 entries in it.
id | code | name
-------------------------
1 | 00001 | Entry 1
2 | 00002 | Entry 2
3 | 00003 | Entry 3
4 | 00004 | Entry 4
5 | 00005 | Entry 5
6 | 00006 | Entry 6
7 | 00007 | Entry 7
8 | 00008 | Entry 8
9 | 00009 | Entry 9
10 | 00010 | Entry 10
I want to be able to prefix the code entries of all lines from id's 1-5 with pre1.
and all lines from id's 6-10 with pre2.
, so I end up with this:
id | code | name
-------------------------------
1 | pre1.00001 | Entry 1
2 | pre1.00002 | Entry 2
3 | p开发者_开发百科re1.00003 | Entry 3
4 | pre1.00004 | Entry 4
5 | pre1.00005 | Entry 5
6 | pre2.00006 | Entry 6
7 | pre2.00007 | Entry 7
8 | pre2.00008 | Entry 8
9 | pre2.00009 | Entry 9
10 | pre2.00010 | Entry 10
Can this be done? Preferably I'd like to use phpMyAdmin or MySQL Workbench but am happy to consider any ways.
UPDATE
yourTable
SET
code = CONCAT(
IF(id BETWEEN 1 AND 5,
'pre1.',
'pre2.'),
code);
Or more general case
UPDATE
yourTable
SET
code = CONCAT('pre1',code)
WHERE
id BETWEEN 1 AND 5;
and repeat for other ranges.
