Parameter / Record Selection option to include or exclude NULL values
Parameter / Record Selection option to include or exclude NULL values
(OP)
Using Crystal Reports XI. I've got a field in our Inventory database called PartCategory and that field has 4 possible values: Y, W, U or NULL.
I'm trying to add a parameter to allow users to select which category(s) they want to include on the report. I've tried adding a static parameter but I can't leave the value as NULL...it doesn't like that. So I decided to do two parameters...one category "Include Categories" for the user to select which categories (Y, W or U) to include and a second parameter "NULL Categories" to either include or exclude NULL categories. Just need some direction on how to setup my record selection to make this happen.
My current record selection is:
{Inventory.Yard} = {?Yard} and
{Inventory.Stock} = {?Stock Numbers} and
{Inventory.PartCategory} = {?Include Categories}
Any help would be greatly appreciated.
Thanks!

For your Categories in the parameter, use the word 'Null'.
Then in your select/formulas if the word 'Null' is selected perform the null check.
Something similar to below but with your actual criteria/database
Create a parameter
--{?Param} values = Yard, Stock, Upper Shelf, None
Edit the record selection formula
--Select Formula =
IF {?Param} = "Yard" then
{Inventory.PartCategory} = "Y"
and {whatever other items needed here}
ELSE
IF {?Param} = "Stock" then
{Inventory.PartCategory} = "S"
and {whatever other items needed here}
ELSE
IF {?Param} = "Upper Shelf" then
{Inventory.PartCategory} = "U"
and {whatever other items needed here}
Else
IF {?Param} = "Null" then
(TRIM({Inventory.PartCategory}) = ""
OR
IsNull({Inventory.PartCategory})=TRUE)
and {whatever other items needed here}
