I have a field which has multiple comma characters in it and I want to
change the first occurrence only.

I can not work out how to do this as replace changes all occurrences.

eg

Field
'fred, bob, june, 12/34/56'
needs to become
'fred^ bob, june, 12/34/56'

where the first comma ',' becomes a circumflex '^'

The first comma can be in any position or not present at all

I imagine it will be something like

set field1= IF(POS(field1,','), CONCAT(substr field1 up to comma, '^',
substr field1 after comma),else field1 Unchanged)

If someone could help before I wipe my whole field I would be most
grateful.

set field1= REPLACE(field1,LEFT(field1,LOCATE(',',field1)),
CONCAT(LEFT(field1,LOCATE(',',field1)-1),'^'))

of course with the check added that there should be a ',' in your `field1`

Many thanks - worked a treat, but it took me a while to work out what
was involved

I guess the old grey matter is just not what it was.
