Limitationen in Crystal Reports 6

Limitationen der Formelsprache

Spezifikation

The maximum length of a String constant, a String value held by a String variable, a String value returned by a function or a String element of a String array is 254 bytes.

The maximum size of an array is 1000 elements.

The maximum number of arguments to a function is 1000. (This applies to functions that can have an indefinite number of arguments such as Choose)

The maximum length of the text of a formula is 64K.

The maximum number of loop condition evaluations per evaluation of a formula is 30,000.

Date-time functions modeled on Visual Basic accept dates from year 100 to year 9999. Traditional Seagate Crystal Reports functions accept dates from year 1 to year 9999.

Anmerkung 1 "Loop Condition Evaluations"

There is a safety mechanism to prevent report processing from hanging due to an infinite loop. Any one evaluation of a formula can have at most 30,000 loop condition evaluations per formula evaluation. This will be explained by the example below. For example:

Local NumberVar i := 1;
While i <= 100000 Do
(
   If i > {movie.STARS} Then
      Exit While;
   i := i + 1
);
20

If {movie.STARS} is greater than 30,000 then the loop condition (i <= 100000) will be evaluated more than the maximum number of times and an error message is displayed. Otherwise the loop is OK.

Note: The safety mechanism applies on a per formula base, not for each individual loop. For example:

Local NumberVar i := 1;
For i := 1 To 10000 Do
(
   Sin (i);
);
While i <= 25000 Do
(
   i := i + 1;
)

The above formula also triggers the safety mechanism since the 30,000 refers to the total number of loop condition evaluations in the formula and this formula will have 10001 + 25001 such evaluations.

Spezifikation

Text Object:
While the effective limit on text object size is 32K (including carriage return and line feed characters), it is recommended that text objects be used only for more manageably sized blocks of text.
