Multiple nested if statements

[#1]

Hi all

Can someone please help me with the following load statement:

Groupings2:

Load *,

If(0 <= seats_reamaining <= 10 , 'A',

If(10 < seats_reamaining <= 20 , 'B',

If(20 < seats_reamaining <= 30 , 'C',

If(30 < seats_reamaining <= 40 , 'D',

If(40 < seats_reamaining <= 50 , 'E',

If(50 < seats_reamaining <= 60 , 'F',

If(60 < seats_reamaining <= 70 , 'G',

If(70 < seats_reamaining <= 80 , 'H',

If(80 < seats_reamaining <= 90 , 'I',

If(90 < seats_reamaining <= 100 , 'J',

If(100 < seats_reamaining <= 110 , 'K',

If(110 < seats_reamaining <= 120 , 'L',

If(120 < seats_reamaining <= 130 , 'M',

If(130 < seats_reamaining <= 140 , 'N',

If(140 < seats_reamaining <= 150 , 'O',

If(150 < seats_reamaining <= 160 , 'P',

If(160 < seats_reamaining <= 170 , 'Q',

If(170 < seats_reamaining <= 180 , 'R', 'Cannot Calculate')))))))))))))))))) as Seat_Class

Resident Groupings1;

I keep getting the following error:

Error in expression:

')' expected

I don't understand this as the correct number of parenthesis is included to close all the if statements. Any help will be greatly appreciated.

ps I'm fairly new to QV.

Hi Andre,

Your Welcome. You can mark the answer as correct if it solved your purpose. Not only this question,but for every question you put up. This will help other peoples to find the answers as if they can have the same query.

Hi Andre,

Did you tried this simple expression?  No need of AND and many conditions

Groupings2:

Load *,

If(seats_reamaining <= 10 , 'A',

If(seats_reamaining <= 20 , 'B',

If(seats_reamaining <= 30 , 'C',

If(seats_reamaining <= 40 , 'D',

If(seats_reamaining <= 50 , 'E',

If(seats_reamaining <= 60 , 'F',

If(seats_reamaining <= 70 , 'G',

If(seats_reamaining <= 80 , 'H',

If(seats_reamaining <= 90 , 'I',

If(seats_reamaining <= 100 , 'J',

If(seats_reamaining <= 110 , 'K',

If(seats_reamaining <= 120 , 'L',

If(seats_reamaining <= 130 , 'M',

If(seats_reamaining <= 140 , 'N',

If(seats_reamaining <= 150 , 'O',

If(seats_reamaining <= 160 , 'P',

If(seats_reamaining <= 170 , 'Q',

If(seats_reamaining <= 180 , 'R', 'Cannot Calculate')))))))))))))))))) as Seat_Class

Hi Jagan, Yes this will too work if we have only positive values.  But if we have negative values then this expression will give 'A' but if we need to display cannot calculate then we have to use that lengthier code.  Choose depending on situation.

[marcus_sommer]

In this case you could use fabs() which returned a positive value.

I always prefer the mapping appoach. To define my mappings I use an external table, like xls or txt. Simmple to maintain and add values, when needed.

[jagan]

Hi,

In that case use this

Groupings2:

Load *,

If(seats_reamaining >= 0,

If( seats_reamaining <= 10 , 'A',

If(seats_reamaining <= 20 , 'B',

If(seats_reamaining <= 30 , 'C',

If(seats_reamaining <= 40 , 'D',

If(seats_reamaining <= 50 , 'E',

If(seats_reamaining <= 60 , 'F',

If(seats_reamaining <= 70 , 'G',

If(seats_reamaining <= 80 , 'H',

If(seats_reamaining <= 90 , 'I',

If(seats_reamaining <= 100 , 'J',

If(seats_reamaining <= 110 , 'K',

If(seats_reamaining <= 120 , 'L',

If(seats_reamaining <= 130 , 'M',

If(seats_reamaining <= 140 , 'N',

If(seats_reamaining <= 150 , 'O',

If(seats_reamaining <= 160 , 'P',

If(seats_reamaining <= 170 , 'Q',

If(seats_reamaining <= 180 , 'R', 'Cannot Calculate'))))))))))))))))))) as Seat_Class

Hi,

This is good. But, For negative values, this will give null.

Just a small change to eradicate this:

Groupings2:

Load *,

If(seats_reamaining >= 0,

If( seats_reamaining <= 10 , 'A',

If(seats_reamaining <= 20 , 'B',

If(seats_reamaining <= 30 , 'C',

If(seats_reamaining <= 40 , 'D',

If(seats_reamaining <= 50 , 'E',

If(seats_reamaining <= 60 , 'F',

If(seats_reamaining <= 70 , 'G',

If(seats_reamaining <= 80 , 'H',

If(seats_reamaining <= 90 , 'I',

If(seats_reamaining <= 100 , 'J',

If(seats_reamaining <= 110 , 'K',

If(seats_reamaining <= 120 , 'L',

If(seats_reamaining <= 130 , 'M',

If(seats_reamaining <= 140 , 'N',

If(seats_reamaining <= 150 , 'O',

If(seats_reamaining <= 160 , 'P',

If(seats_reamaining <= 170 , 'Q',

If(seats_reamaining <= 180 , 'R', 'Cannot Calculate')))))))))))))))))),'Cannot Calculate') as Seat_Class

Resident Groupings1;

[marcus_sommer]

See above and use fabs().

[timanshu]

Hi Marcus,

fabs() will make the value positive and then it will come under any of groups 'A' to 'R' , which is not correct.

[marcus_sommer]

I understand your remark about negative values that they should be handled like positive values then otherwise all negatives will return "A". What should be the result from negative values NULL, 'Cannot Calculate' or ....
