We have a requirement to normalise 15 million historical transactions into a number of tables. This involves various transformation processes currently implemented in T-SQL stored procedures. Current thinking is to process the transactions in T-SQL, driven by a cursor (probably [url=https://sqlperformance.com/2012/09/t-sql-queries/cursor-options]FAST_FORWARD, LOCAL [/url]) , invoking the stored procedures as required. Would welcome thoughts on the viability of such an approach and any suggestions of alternatives
