| I need to select a multitude of data 15 years out then pivot it into another table for Reports.I have 2 tablesTable1 ( key1 , key2, incDate )Table2 ( key1 , key2, amount, paidDate)key1 and key2 hold the relationship between these two tables. I need to get all data from Table2 that starts from the incDate from Table1 and goes out 15 years. I will need to have a running total of the amount starting at year1( the incDate year) and going out 15 years from that. I can grab the data found with a simple group by, but how do I also continue my running total for the remaining years? After that I will need to pivot this data into another table with columns like year1, year2, year3, etc. I will need 1 row in this new table for every row from Table1.Thanks. |

| I did come up with a solution to cross into a numbers table and achieved setting up the correct years to update for each of my sets. I then updated the amounts and running totals. This is 3 processes and takes quite a while to do. I have about 170k rows and for 15 years that is quite a bit of rows to insert into a temp table before I pivot it. |

| No to pivot over 2 million rows. Currently the longest time in my query is to cross join the nums table to get data from Table1 setup for 15 years. |
