Just wondering whether there is a way to check columns of a table reached thire maximum length.
With following I was able to get the length of the table column
SELECT MAX(CHARACTER_MAXIMUM_LENGTH) AS LEN, COLUMN_NAME
FROM information_schema.columns
WHERE table_name IN ('TableA')
GROUP BY COLUMN_NAME
ORDER BY LEN DESC
And then I wanted to check whether those column reached its MAX length or not with data
Below gives the max length a column
SELECT MAX(LENGTH(Col1))
FROM TableA
As it is not possible to use aggregate functions in WHERE
clause, how it is possible?
Thanks
