B

bitmap

A graphic file that can be added to a report.

BLOB field

A BLOB field is a field containing BLOB data. A BLOB (Binary Large Object) is simply a bitmapped graphic that has been entered into a database. Placing a BLOB field on your report allows you to access these graphics as you would other data types.

Boolean expression

A Boolean expression is an expression that defines a logical relationship between two or more items. A Boolean expression is either TRUE or FALSE. A>5 And B<10 is a Boolean expression that uses the Boolean operator And. For the expression to be TRUE, both conditions (joined with the And operator) must be true. The value of A must be greater than 5 and the value of B must be less than 10. If the values do not fall into those ranges, then the expression is FALSE. Boolean expressions are useful in If-Then-Else formulas. For example:

If A>5 And B<10 Then 

    "In Range" 

Else 

    "" 

This Crystal syntax formula says: if the Boolean expression A>5 and B<10 is TRUE, print "In Range" otherwise (if the Boolean expression is FALSE), print nothing (as designated by the empty string"").

Boolean

Boolean formulas are formulas that return a Yes/No (TRUE/FALSE) value. For example, the Boolean formula {orders detail.QUANTITY} > 6 compares the value in the {orders detail.QUANTITY} field to 6. If the value is greater than 6 it returns a Yes; if it is 6 or less, it returns a No. Contrast this with a non-Boolean formula like {orders detail.QUANTITY} * 6. In this case the program returns a number, the value of {orders detail.QUANTITY} multiplied by 6. All selection formula and group selection formulas must be Boolean.
