Stored procedures
Removes duplicates among substrings of a string, based on one or more separators.
Example
// Removes duplicates
StringDeleteDuplicate("France, Italy, Germany, Spain, France", ", ")
// Returns "France, Italy, Germany, Spain"
Syntax
<Result> = StringDeleteDuplicate(<Initial string> , <Separator> [, <Comparison>])
<Result>: Character string
String without duplicates.
<Initial string>: Character string
String with duplicates.
<Separator>: String or array of strings
This parameter can correspond to:
  • The string that separates the substrings. This separator is case sensitive.
  • An array of strings. The different strings in the array delimit the substrings. These separators are case sensitive.
If this parameter is not specified, the default separator is TAB.
<Comparison>: Optional integer
Comparison options:
ccIgnoreAccentAccent-insensitive comparison
ccIgnoreCaseCase-insensitive comparison.
ccIgnoreInsideSpaceComparison ignoring spaces within strings.
ccIgnorePunctuationAndSpaceSpace and punctuation-insensitive comparison.
ccIgnoreSpaceComparison ignoring spaces before and after strings.
ccNormal
(Default value)		Standard comparison, equivalent to the '=' operator.
Remarks
  • In case of duplicates, only the first occurrence of the substring from the original string is kept in the result string.
  • The characters taken into account for punctuation and spaces are provided by the system. To get the list of these characters, write the following WLanguage code:
    s is string
    FOR i = 0 TO 255
    IF Charact(i) <> StringFormat(Charact(i), ccIgnorePunctuationAndSpace) THEN
     s += Charact(i)
    END
    END
