I need a query in SQL to combine several rows in the same table.
L_Life_Amount M_LifeAmount L_Health_Amount M_Health_amount 100 200 300 400 200 300 400 600 300 400 500 700
and I need to bring the below result set
InsuranceType L_Amount M_Amount L_amount-M_amount Life amount 600 900 -300 Health amount 1200 1700 -500 Total 1800 2600 -800
Here I need to sum the values of L_life_Amount(L_Amount) and sum of M_Life_amount(M_Amount) and display it as Life amount
the same way I need to do sum for L_Helath_Amount(L_Amount) and sum of M_Health_Amount(M_Amount) and display it as Health Amount
Finally I make the diff betweeen L_amount and M-amount and make a total of it.
