Title: Message

Substr(''mystr1~mystr2~mystr3', 1, 20) => 1 is the position and 20 the length (not the position).
The "substring" functions return a portion of string, beginning at character position, substring_length characters long.

SELECT substr('mystr1~mystr2~mystr3',1,instr('mystr1~mystr2~mystr3','~')-1) W_First,
               substr('mystr1~mystr2~mystr3',instr('mystr1~mystr2~mystr3','~')+1,
                         (INSTR('mystr1~mystr2~mystr3', '~', 1,2)-1)-(INSTR('mystr1~mystr2~mystr3','~',1,1)) ) W_SECOND,
               substr('mystr1~mystr2~mystr3',instr('mystr1~mystr2~mystr3','~',1,2)+1,length('mystr1~mystr2~mystr3')) W_THIRD

Subject: String manipulation

I'm trying to separate a string into 3 values:
The string is:
mystr1~mystr2~mystr3

Here is the code so far:
  1  select substr(subject,1,instr(subject,'~')-1) first,
  2  substr(subject,instr(subject,'~')+1, instr(subject,'~',1,2)-1) second,
  3  substr(subject,instr(subject,'~',1,2)+1,length(subject))
  4  from test_table
  5  where test_column=1700455

The result I get is:
mystr1
mystr2~mystr3
mystr3

The result I want is:
mystr1
mystr2
Mystr3

TIA,
