Обсуждение: Update value to "the first character is capital and the rest is small"

Hello all,

Does anyone have available plpgsql codes to update all capital letters
in a column to "the first character is capital and the rest is small" ?

For example, in tableA(id, description)
001,  'ZHANG ZHE XIN'                                              =>
'Zhang Zhe Xin'
002,  'LIU, WEI-HUAI'
=>    'Liu, Wei-Huai'
003,  'GU & WEI. NAN (CE SHI) & TOMMORROW'      =>   'Gu & Wei. Nan (Ce
Shi) & Tommorrow'

Thanks a lot!
Ying

I don't know about plpgsql codes, but there is a function initcap() that
you can use for that.

alvherre=# select initcap('GU & WEI. NAN (CE SHI) & TOMMORROW');
              initcap
------------------------------------
 Gu & Wei. Nan (Ce Shi) & Tommorrow
(1 row)

I got the answer from the docs. |initcap|(text)

thanks anyway,

Have you tried the initcap function?

  select initcap('abcd efgh');
   initcap
-----------
  Abcd Efgh
