Thread: JDBC problem with DELETE

The following piece of code:
  stmt.executeUpdate("delete from friend where name='"+someName+"'");

is returning:
  SQLException: java.sql.SQLException: ERROR: Attribute 'John Doe' not
found

where someName is "John Doe".

Any ideas?  The row where name='John Doe' is definitely in the table and I
can execute the statement without problems from psql.

Thanks in advance for your help.

//Dave

Does this happen when you run the sql from psql?

How about using PreparedStatement instead of Statement? It would then handle
the quoting correctly (which is what I'm thinking is going wrong here).

Let me answer this one... ;)

> found

Remember that an 'Attribute' is a "field" in PG.  PG is taking this as
WHERE fieldname "name" = fieldname "someName";  PG is somehow receiving
double quotes around 'someName'.  I don't do java, so you figure this one
out..

Change the quoting on someName to single quotes and it should 
work.  Single quotes aroung strings, double quotes around field
names.  Note that double quotes around field or table names are only
required if you need to preserve uppercase letters in the name.(..someone correct me if I'm not right about this...)

Hello!

How do i change the default (ISO) date/time format to (Postgres) format?
I need to 'SET DATESTYLE TO Postgres' for every session, is there a way
to set this permanently?

I'm using postgres 7.0.2 over linux.

Peter,

The sql does work from psql.

I also tried your suggestion about using PreparedStatement and that worked!

Am I doing something wrong with Statement or is it a bug?

//Dave

http://postgresql.org/docs/postgres/x1137.htm sez:

There are several ways to affect the appearance of date/time types: 
The PGDATESTYLE environment variable used by the backenddirectly on postmaster startup. 
The PGDATESTYLE environment variable used by the frontendlibpq on session startup. 
SET DATESTYLE SQL command. 


These should be sufficient. You can also adjust a #define in a header
file and rebuild Postgres. Look for something with "DATESTYLE" in the
include directories.

I'm not sure, but it might be loosing the quote somewhere.

The proper safe way is to use PreparedStatement. I'll try it here just to
make sure it isn't a bug though.

Thanks, Peter.  Please let me know if you see anything.

I can't see how my Java code could be losing the single quotes.  It is such
a simple statement.  But then again, I have made obvious coding errors that
I just can't see a time or two in the past.  :-)

Why is PreparedStatement the proper safe way?  From a coding perspective, it
takes more lines of code and it would seem to also require slightly more
computation as well.

PreparedStatement is the proper way, because it allows for differences
between implementations of SQL and how data types are handled. It's mainly
for code that can use different database engines.

ie: setString() will automatically add quotes whereas you have to do this
yourself with Statement. Also, not all quotes are '. There's a method in
DatabaseMetaData that returns the current quoting character (which we hard
code to '). This allows some engines to use different characters.

Also when you start using some of the more special types, PreparedStatement
will handle them better than you could - look at
setTimestamp()/getTimestamp() for an example... It's easier to keep the
driver in line with the backend (the format returned changed) than to change
everyone's code.

Dave,

Um... just thought I'd ask...

Are you really using "John Doe" (as in the email)
or is that just a dummy placeholder for the real
names you inserted?

The reason why I ask is that I remember the first
time I was bit by the ole single quote problem was
dealing with an 'O'Connor' that, of course, really
should have been an 'O''Connor'.  Thought maybe
something similar was happening here...

-Tim.

Tim,

It is not really "John Doe", but it also does not have any embedded single
quotes.  It does, however, have an embedded space character.  I don't know
if this has anything to do with it, but it is the only thing I can think of
that is different than line 380 in Peter's example file ImageViewer.java.
