I have a table that has families_id
, date
, metric_id
A record gets inserted for each families_id
there will be a date
& metric_id
1-10.
So there should be 10 records for each families_id
, the records get inserted with a date an each should follow on from each other. So metric_id
10 date should be greater than metric_id
6 date.
On mass how can I select where they have
metric_id
metric_id
6 is before the date for metric_id
2use row_number to assign an ordinal to the metric_id and date for each family, then they should match - also metric_id, 1,2,3,4... should match with its calculated row_number(), also 1,2,3,4....
SELECT IQ.* FROM (SELECT families_id, [date], metric_id,
ROW_NUMBER() OVER (PARTITION BY families_id ORDER BY [date]) rn_date,
ROW_NUMBER() OVER (PARTITION BY families_id ORDER BY metricid) rn_metric FROM YourTable) IQ
WHERE IQ.rn_date != IQ.rn_metric;
--should detect wrongly ordered metric_ids
SELECT IQ.* FROM (SELECT families_id, [date], metric_id,
ROW_NUMBER() OVER (PARTITION BY families_id ORDER BY [date]) rn_date,
ROW_NUMBER() OVER (PARTITION BY families_id ORDER BY metricid) rn_metric FROM YourTable) IQ
WHERE IQ.metric_id != IQ.rn_metric;
Another possibility - detect a metricID where the date is earlier for a higher id
SELECT y1.families_id, y1.metric_id FROM yourtable y1
WHERE
EXISTS(SELECT 0 FROM yourtable y2 WHERE y1.families_id = y2.families_id
AND
y2.date < y1.date
AND
y2.metricid > y1.metricid)
