mersi baieti f mult

mai am de facut functia asta:

FUNCTION Similar (tcStr1, tcStr2) 
* Compares two strings. Returns a numeric
* indication of their similarity (0 = not
* at all similar, 100 = identical).

* Written by Mike Lewis, June 2002

LOCAL lcOK
PRIVATE pnScore

* Convert each string to simplest form (letters
* and digits only, all upper case)
tcStr1 = UPPER(tcStr1)
tcStr2 = UPPER(tcStr2)
lcOK = "ABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890"
tcStr1=CHRTRAN(tcStr1,CHRTRAN(tcStr1,lcOK,""),"")
tcStr2=CHRTRAN(tcStr2,CHRTRAN(tcStr2,lcOK,""),"")

IF EMPTY(tcStr1) OR EMPTY(tcStr2)
  * One or both of the strings is now empty
  RETURN 0
ENDIF

IF tcStr1 == tcStr2
  * Strings are identical
  RETURN 100
ENDIF

* Initialize cumulative score (this will be the
* total length of all the common substrings)
pnScore = 0

* Find all common sub-strings
FindCommon(tcStr1,tcStr2)

* We now have the cumulative score. Return this
* as a percent of the maximum score. The maximum
* score is the average length of the two strings.
RETURN pnScore*200 /(LEN(tcStr1)+LEN(tcStr2))

ENDFUNC 

da parca ar fii mai indicat sa o fac in C# ,de fap pe amandoua

dar exista o fct similar si stored procedure?
