here's my problem (current one).
I have a table in which there is a GIN column. There can be multiple GIN numbers that are the same. What i need to do is set the "COUNT" columns value equal to the number of GIN numbers that are the same. For instance, if i have four rows with GIN # '100', each "Count" value for that GIN number should indicate "4", and so on. How might i be populating the COUNT column in this case? DDL follows:


CREATE TABLE [dbo].[426warrants](

you can use aggregate function using PARTITION BY

so to get count grouped by GIN use

COUNT(1) OVER (PARTITION BY GIN) AS GINCount

and include in your insert statement to populate count field
