Somehow I think jhonatan is lysdexic and really should be spelled Johnathon, but… what do I know? I’m just a stupid American.

I solved problem for jhonatan:

–because you don’t use northwind database I
–have to create table and populate
–first with your data which makes no implicit sense
CREATE TABLE patientsurveys (
ps_id INT,
q1_1 INT,
q1_2 INT
)

INSERT INTO patientsurveys (ps_id, q1_1, q1_2) VALUES (1010101, 1, 19840101)
INSERT INTO patientsurveys (ps_id, q1_1, q1_2) VALUES (1010101, 2, 19840101)
INSERT INTO patientsurveys (ps_id, q1_1, q1_2) VALUES (1020232, 1, 19840409)
INSERT INTO patientsurveys (ps_id, q1_1, q1_2) VALUES (1020256, 1, 19440103)
INSERT INTO patientsurveys (ps_id, q1_1, q1_2) VALUES (2020225, 2, 19450604)
INSERT INTO patientsurveys (ps_id, q1_1, q1_2) VALUES (2020232, 1, 19840409)
INSERT INTO patientsurveys (ps_id, q1_1, q1_2) VALUES (2060354, 2, 19900303)

–this is the form of the query you are asking for, no?
SELECT
ps_id,
CONVERT(BIT,CASE WHEN (COUNT(q1_1) > 1) THEN 0 ELSE 1 END) AS STATUS
FROM
patientsurveys
WHERE
ps_id IN (SELECT ps_id FROM patientsurveys GROUP BY ps_id HAVING COUNT(*) > 1)
GROUP BY
ps_id

–be sure to drop this table now, since it makes no sense and
–serves no usefulness either here now, or in the future
DROP TABLE patientsurveys

Just a question.

How can I compare 2 rows of a table? Just want to get a boolean value: 1 means the 2 rows are identical; 0 means they’re different.

I’ve tried using “group by”

Query

select ps_id, q1_1,q1_2
from patientsurveys
group by ps_id, q1_1,q1_2

Results

PS_ID Q1_1 Q1_2
1010101 1 19840101
1010101 2 19840101
1020232 1 19840409
1020256 1 19440103
2020225 2 19450604
2020232 1 19840409
2060354 2 19900303

The 2 firsts rows are identical except for Q1_1 column (1 vs 2). I want my query to return just 1 row like this:

PS_ID STATUS
1010101 0 (means rows are different)

And, the table really has around 200 columns, so is there any way to do this dynamically?

Thanks

I didn’t install sp3 for sql server 2000, is this problem or other problems?
