Обсуждение: replace function in a query
Hi,
I have to write a query that does the following.
select column_x from tbl_xyz
where column_y = 'abc def ghi'
new line characters i.e. '\n' in column_y should be replaced with a space character i.e. ' ' in this query.
Is there any replace function that when used in the query with colulmn_y would do it?
Thanks,
~Harpreet

Are you looking for something like this? test=> SELECT translate ('abc test'> def test'> ghi', E'\n', ' '); translate ------------- abc def ghi (1 row) "translate" is described on http://www.postgresql.org/docs/current/static/functions-string.html Yours, Laurenz Albe
