Syntax

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

Generators: .NET, Java, Ruby (up to GeneXus X Evolution 3), Visual FoxPro (up to GeneXus X Evolution 3)

Description

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.
