Thread: Appended '+' in Column Value
One column in a table has values for the attribute 'stream'. Some queries
return some rows where a stream name (only identified one so far) has an
appended '+'. I cannot update the table to remove that appended character,
and I've not seen this before.
Example:
2220 | STV | 2012-07-12 | Nematoda | | |
| | Omnivore | 50 | | StarvationCrk+| Owyhee
| | | | | |
| | | | | |
2701 | STV-10 | 2013-07-10 | Nematoda | | |
| | Omnivore | 36 | | StarvationCrk | Owyhee
I'd appreciate learning where that '+' originates and how to get rid of
it. A query to count the rows with the appendage returns zero:
select count(*) from benthos where stream = 'StarvationCrk';
count
-------
204
select count(*) from benthos where stream = 'StarvationCrk+';
count
-------
0
TIA,
Rich

Is this only in psql? If so I would suspect the table formatting code. What happens if you do \x and then look at the records? > > Example: > > 2220 | STV | 2012-07-12 | Nematoda | | | > | | Omnivore | 50 | | > StarvationCrk+| Owyhee > | | | | | | > | | | | | | > 2701 | STV-10 | 2013-07-10 | Nematoda | | | > | | Omnivore | 36 | | StarvationCrk > | Owyhee > > I'd appreciate learning where that '+' originates and how to get rid of > it.

Yeah, means either whoever inputted the data kept hitting Enter after each string(most of the time) or whatever program input the data added \n. > > Thanks, > > Rich > > -- Adrian Klaver adrian.klaver@aklaver.com

BTW, see \pset (particularly the linestyle option) in the psql man page
for documentation of this behavior and the options for changing it.
