RE: PHP, Oracle and bind variables

Jack,

 

            I see two possible problems.  

 

1)       Since your saying that the date is going in as a varchar I have
to assume that the table's definition has it as a varchar vs a date.
Change the timestamp column to date & that will correct part of the
problem.

 

2) Wrap the datum bind variable in the to_date function.  PHP sees it as
a character string & binds it as such.

Hi List 

 

 

I am trying to load data from a file into an oracle table.

the file is in matrix format (rows is timestamp and columns are sids
where the value is a status)  and needs to be put into the table as rows
as the number of columns is variable in time

so the layout of the table is 

 

dbname varchar2(20)

timestamp varchar2(20) ---> this I would like to change to date

status varchar2(6)

 

I have created a little code that loops through the files and the data
in the files and inserts the data into a table. the first row contains
the sids and should not be loaded, but just used in every insert.

 

>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> 

function insert_OLA_data_2($file_in)
{
global $conn, $FileDir; //define variables as global
$lines = file($FileDir.$file_in,FILE_IGNORE_NEW_LINES |
FILE_SKIP_EMPTY_LINES);
$line_n=0;
$stmt = oci_parse ($conn,"insert into OLA_DATA2(DBNAME,TIMESTAMP,STATUS)
values (:dbs,:datum,:stat)");
foreach ($lines as $line_num => $line) 
{
if ($line_n < 1 )
{
$a_dbs=explode(',',rtrim($line));
}
else
{
$a_line=explode (',',rtrim($line));
$cntr=1;
for ($item_num=0;$item_num < count($a_line)-1; $item_num++)
{
oci_bind_by_name($stmt,"dbs",$a_dbs[$cntr]);
oci_bind_by_name($stmt,"datum",$a_line[0]);
oci_bind_by_name($stmt,"stat",$a_line[$cntr]);
oci_execute($stmt,OCI_DEFAULT);
$e = oci_error($stmt);
if(count($e) > 1)
{
log_message('Error while loading file '.$file_in.'('.$e['message'].')');
}$cntr=$cntr+1;
}
}
$line_n=$line_n + 1;
}
$commited = oci_commit($conn);
move_files($file_in);
log_message('File '.$file_in.' processed');
}//EoF insert_OLA_data_2

>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>

I am using bind variables as there are many executions of the same query
with different values.

Above code works fine, but the date is going into the database as a
varchar and I would really like it to go in as a date
Anyone done this and can point me in the right direction?

 

format for the string containing the date is 2008:07:29:12:15:00
