Built by the engineers behind Netezza and the technology behind Amazon Redshift, AnzoGraph is a native, Massively Parallel Processing (MPP) distributed Graph OLAP (GOLAP) database that executes queries more than 100x faster than other vendors.  

The below given query will fetch the duplicate rows in MSSQL with number of occurance of each row.

SELECT     <all column names - comma seperated>, COUNT(<name of any one column>) AS Occurance_Count
FROM <table name>
GROUP BY <all column names - comma seperated>
HAVING (COUNT(<name of any one column>) > 1)

 

Note: The data in '<>' should be replaced with relevent data. E.g. '<all column names - comma seperated>' should be replaced with 'a,b,c' where a, b and c are the names of the columns in the table.

Download AnzoGraph now and find out for yourself why it is acknowledged as the most complete all-in-one data warehouse for BI style and graph analytics.
