Searches for a string within a string in reverse order.
StrSearchRev( str1, str2 [ , start_char ] )
Where:
str1
String on which the search will be done. It may be of the Char, Varchar or Long varchar type.
str2
Search string. It may be of the Char, Varchar or Long varchar type.
Start_char
Optional. It indicates the search start position. This variable is of the positive number type.
Type Returned:
Numeric
Objects: Procedure, Transaction, Web Panel, Panel, Data Provider
Generators: .NET, .NET Framework, Java, Ruby (up to GeneXus X Evolution 3), Visual FoxPro (up to GeneXus X Evolution 3), Apple, Android, Angular
StrSearchRev returns the position of the Str1 string where the Str2 string was found. It searches from back to front. If the last parameter is omitted, it searches from the final position of the Str1, backwards.
If the search is not successful, it returns to 0.
Notes:
- The StartChar parameter is of the positive number type and indicates the initial position of the search within the Str1. If 0, the function returns 0.
- The comparison between characters is case-sensitive; i.e.: 'a' is different from 'A'.
- If Str1 is empty or the length is shorter than Str2, the function returns 0, since the search cannot be carried out.
- If Str2 is empty, it returns StartChar if it was initialized; otherwise, it returns StrLen.
