Hi Folk
I have a databse with a bunch of double entries in some fields. For
example:
field A:
"that is the way to go that is the way to go "
field A should be:
"that is the way to go "
Is there some sort of sql I can use to find these (and clean them up)?
TIA

Yep. Assuming they really are exact doubles (phrase,space,phrase)
here's one way:
SELECT TRIM( SUBSTR(
fieldA, 1, FLOOR( LENGTH( fieldA ) /2 ) )
)
START , TRIM( SUBSTR(
fieldA, CEILING( LENGTH( fieldA ) /2 ) )
)finish
FROM mytable
HAVING START = finish
LIMIT 0 , 30
>(and clean them up)?
I'll leave that as an execise for the reader. WARNING: BACK UP YOUR
