Hello,

I am trying to update a column, T_ALT_DESC of PASTMSTR table which has data in Upper Case. I need to convert the data into sentence case. For example,
T_ALT_DESC = ELECTRA GLIDE CLASSIC FLHTC (SOLID) should be

T_ALT_DESC = Electra Glide Classic Flhtc (Solid).

T_ALT_DESC has several other values which need to be converted.

Is it possible with DB2 Update Clause.

Thanks
Sri

Sri50131,

It can be done in sql but it would be real ugly using atleast 3 scalar functions. Since it is an update I suggest doing it programatically.

kolusu,

I do not have time to do it programatically 'coz we are going live soon. This would be one time thing, so, I would really like to do it thru' SQL.

Thanks

well,

the general idea may be like this:


Code:

   SELECT
    UCASE (SUBSTR(<my field>,1,1))
 ||
    REPLACE (
    REPLACE (
    REPLACE (
    REPLACE (
         LCASE(SUBSTR(<my field>,2)), ' a',' A')
                                    , ' b',' B')

                                    , ' t',' T')

                                    , ' z',' Z')

      FROM ...


regards,
bauer
