Question

Hi ,
I have String value in table now I require to check that value is valid or not .
I have below Query .
SELECT *
FROM Table TCI
WHERE (ISDATE(SUBSTRING(SUBSTRING(Data,82,6),1,4)+'-'+SUBSTRING(SUBSTRING(Data,82,6),5,2)+'-'+'01')<>1 OR LEN(LTRIM(RTRIM(SUBSTRING(Data,82,6)))) < 0 OR SUBSTRING(Data,82,6)='000000')
AND (LEN(LTRIM(RTRIM(SUBSTRING(Data,88,6)))) < 0 OR SUBSTRING(Data,88,6)= '000000' OR ISDATE(SUBSTRING(SUBSTRING(Data,88,6),1,4)+'-'+SUBSTRING(SUBSTRING(Data,88,6),5,2)+'-'+'01')<>1)
AND (LEN(LTRIM(RTRIM(SUBSTRING(Data,173,6)))) < 0 OR ISDATE(SUBSTRING(SUBSTRING(Data,173,6),1,4)+'-'+SUBSTRING(SUBSTRING(Data,173,6),5,2)+'-'+'01')<>1)

I need only invalid record set from below Query ;
like; If it is not isdate and is_numeric type for particular row then it return only that row.
currently i'm facing issue like whole string is invalid in that case it gives row .
should I use case statement in where clause ?
Thanks

Hi PrajapatiNeha,
Your requirement is confusing. Judging from the query, the column data
seems to be a string which consists of fixed length date or numberic format substrings, so you are verifying each substring is valid and need to select the invalid substrings?
If that is your requirement, why not just extract the substrings into a derived table and filter based on the derived table?  The substrings in the derived table will give a more directly overview of your long data string.
If you have any question, feel free to let me know.
