Hi all!
I cannot share the code, but maybe someone can gibve me an idea...
I have to lookup something in a database (updates from specific time,
MS SQL Server), and check them in another database (Oracle). Both might
contain multiple rows, which makes this big...
The point is, that the code below runs at app 10 rows/second, which is
slow... any ideas how I can do it better?
The slow thing is that for each row in DB1, I run a query in DB2.
The code is basically this - there is some more, but
// get data from MS SQL
$result2=odbc_exec($conn2, $sql);
while(odbc_fetch_row($result2) )
{
// test for this is Oracle DB (here might be multiple rows too)
$sql2= select....
$result=odbc_exec($conn, $sql2);
// if row exist
while(odbc_fetch_row($result))
//if(odbc_num_rows($result)>1)
{
// add to array - for next step to search - do not add twice
$k=count($part1)-1;
while(($k>-1) && ($part1[$k]!=odbc_result($result2,1)) &&
($part2[$k]!=odbc_result($result2,2)) &&
$part8[$k]!=trim(odbc_result($result,1)))
$k--;
if($k==-1)
{
$part1[]=trim(odbc_result($result2,1));
$part2[]=trim(odbc_result($result2,2));
$part3[]=trim(odbc_result($result2,3));
$part4[]
ASO....
