Subj:   Re: String extraction in teradata
 
From:   debojit.pal

Hi Abhishek,

I am not sure if there is any inbuilt function in TD to do this but you can use the following query (had a tough time with the parentheses :)) -

     Sel substr ('ab-cd-ef', 1, (position('-' in 'ab-cd-ef') -1)) as  col1,
     substr((Substr('ab-cd-ef', (Position('-' In 'ab-cd-ef') +1), 20)), 1, (Position('-' In
     (Substr('ab-cd-ef', (Position('-' In 'ab-cd-ef') +1), 20))) - 1)) as col2,
     substr((Substr('ab-cd-ef', (Position('-' In 'ab-cd-ef') +1), 20)), (Position('-' In
     (Substr('ab-cd-ef', (Position('-' In 'ab-cd-ef') +1), 20))) + 1), 20) as col3;

Please note, that this will work only for your given example i.e. if your string has 3 sets of alphabets separated by two dashes. If your string has more sets of alphabets then you would require more nesting or use stored procedures.


Thanks,

Debojit.
