Hi ,

Is there any way , I can write a Select statement in SPUFI to extract those records from a table where the column defined as LONGVARCHAR contains specific value.

Regards
PRM

prmohanty,

Did you try LIKE predicate? Read upon it here and also the examples at the bottom of the link

Am I missing something? Would it not be as easy as:

Select
FIRST_NAME,
LAST_NAME,
FROM YOUR_TABLE
WHERE LAST_NAME = 'SMITH'

LAST_NAME is LONGVARCHAR

Nasacar,

I think OP wanted to search for a specific string any where in the long varchar colum

ex: if the column consists of the following

Code:

NASCAR
The official site of NASCAR is Nascar.com
NASCAR delivers exciting finish‎
The National Association for Stock Car Auto Racing (NASCAR) is a family-owned ...


Your SQL would only fetch the 1st row where as a LIKE predicate will fetch all the 4 rows

however if you change the where clause to

Code:

WHERE  LAST_NAME LIKE '%NASCAR%'


will fetch all the rows

Thanks kolusu for clarification. When I read the request it sounded LIKE he was searching for a set string.

Your LIKE example makes perfect sense to me!
