pg_put_line() Frustration

From

Hi all,

I am currently working on an application that will input multple lines into
a Postgre database. I am using the following code

  $sql = "COPY table_2 FROM STDIN DELIMITER AS '\t'";
  pg_query($dbc, $sql);
  $sql = $data1."\t".$data2."\t".implode("\t",
$data)."\ttrue\t05-05-2005\n";
  pg_put_line($this->dbc, $sql);
  if(!pg_put_line($dbc, "\\N"))
  {
    pg_end_copy($dbc);
    $error_message('Could not enter details');
  }
  else
  {
     pg_end_copy($this->dbc);
     unset($data);
  }

This gives me an example line like

57    BELF    254    0    10877    5138    0    0    true    05-05-2005

To go into a table with fields INT, CHAR(4) INT, INT, INT, INT, INT, INT,
BOOL, DATE

However, its not going in...

I'm getting an error

ERROR:  missing data for column "col2"

With no data being inserted.

If anyone could point out where I'm going wrong I'd be forever in their debt

Thanks

Simon

It's PostgreSQL or Postgres, not Postgre.

The last line above attempts to add a row with a single NULL value,
so you get an error about missing data for the other columns.  What's
the purpose of that line?  Why do you sometimes use $dbc and sometimes
$this->dbc?  Do they refer to the same connection or to different
connections?

Use pg_copy_to and pg_copy_from instead...
