Can you check in SQL if a fields can be encoded using specified charset
Started by Paul Taylorover 15 years ago2 messagesgeneral
Is there a function that can say whether a textvalue can be encoded in a
particular charset
i.e.
SELECT FIELD1 FROM TABLE1 WHERE ENCODE_AS_IS08859(FIELD1)=true
thanks Paul

See convert() and friends here:
http://www.postgresql.org/docs/9.0/interactive/functions-string.html#FUNCTIONS-STRING-OTHER
That will issue an error when the text can't be converted, but you could
have a plpgsql function catching the exception for you and returning
false. Won't be very fast, but will do the job.
