SQL

We have requirement in Crystal report where we have to implement 2 concept in one column. For eg: in below screenshot,  if we have numbers we need to sum up and display as one row.  if it is variable row. It should remain as single row.
Material Quantity Price
O Ring 1 5.61
O Ring 1 Fixed
O Ring 1 5.61
O Ring 1 Fixed

Output should be,
Material Quantity Price
O Ring 1 11.22
O Ring 1 Fixed
O Ring 1 Fixed

Kindly pour us some suggestions if any.

    if {SM07.FNSM07InclFixPrice} = "0" or {InvParameters.FNInvParametersFixPriMatICU} = 0 then
        ToText ( {CalcMaterial.FNCalcMaterialOrderDiscount},{CalcTotals.FNCalcTotalsAmmdec})
    else 
        "Fixed"
)
Else
