I'm trying to do this:
if (counter != -1) /* No ha habido ningún error */
{
PreparedStatement pstmt=null;
sql="insert into tar_historico values (?,?,?)";
razon="<br>Query: " + sql;
try {
pstmt = con.prepareStatement(sql);
pstmt.setString(1,Integer.toString(counter));
pstmt.setString(2,"1");
pstmt.setTimestamp(3,new Timestamp(new
java.util.Date().getTime()));
pstmt.executeUpdate(sql);
pstmt.close();
con.close();
}
But I get this error message in the PostgreSQL log:
query: insert into tar_historico values (?,?,?)
ERROR: parser: parse error at or near ","
What could be the problem? I've tried everything and I haven't found the
solution yet. Please, help.
Thanks in advance,
Esteban Chiner

How about:
sql="insert into tar_historico values ('?','?','?')";

What are the (Postgres) datatypes of the fields?
The best would be to know what the final format of the query became. For
this you have to run the postmaster with -d2 or something, to create a
debug-level log. It will show you the statements as they were passed to the
backend.
My personal suspicion is that your first two fields are numeric fields, not
string fields.

My suspicion aswell. Most people forget that setString() wraps the string
in quotes when the query is sent to the backend.
