    Posted: 07 Feb 2008 at 9:15am
I have a field on my report that I want to return like this...Here is my SQL code If I were to do it in SQL.  How can I return the same thing on my report in Crystal Syntax?

SUM(CASE KILSHEET.Contract WHEN 1 THEN ((TOT_CARC_WEIGHT / 100) * 1.75) ELSE 0 END)

I would create a manual running total and replace the Case statement with an IIF() function.
Global NumberVar ContractTotal;
ContractTotal := ContractTotal + IIF({KILSHEET.Contract}=1, (TOT_CARC_WEIGHT / 100) * 1.75, 0);

Then in the report footer (or where ever you want the total to be printed), put this formula to print the value:
Global NumberVar ContractTotal;
ContractTotal;

I have all the Crystal Reports functions documented with sample code in Chapter 7 of my book Crystal Reports Encyclopedia.

That's weird. You are defining the variable here. Are you using Crystal Syntax?

Do you have an apostrophe as the first character on that line, or is that a typo in your message? There should not be an apostrophe on the line anywhere.

Global Numbervar ContractTotal;

Is there another alternative to doing this with just an immediate if or CASE statement?

To be honest, I don't know what is going on with your reports. I looked at both posts you have on the forum and the code I give you works fine on my computer. Yet you get strange errors when you run it. There is something odd happening, but I have no idea where the problem is.

Anyway, another way to do you SELECT statement is to create a formula with only the IIF() statement.

IIF({KILSHEET.Contract}=1, (TOT_CARC_WEIGHT / 100) * 1.75, 0);
And add that to your report in the Details section. Then right-click on it and select Insert > Summary. That will give you a total at the end of the report.

I just noticed something here, re-reading the thread.  Where exactly are you putting this formula?  You should just be creating a new formula field, and adding the field to the details section.  It sound instead like you are trying to assign and manipulate variables inside a running total condition.  Which could throw errors.
