I have a php script which is read by batch file. This php script is parsing 1 line of row from mssql, process it and inserts it to another table. This is currently procsssing 1 data per 1 to 3 seconds. I wish to make it faster. Any ideas are welcome.

 

Here's the code i did.

<?php

              // Connect to the database (host, username, password)
              $con = mssql_connect('XXXXXXXXXXXXX','sa','XXXXXXXXX') 
                  or die('Could not connect to the server!');
               
              // Select a database:
              mssql_select_db('XXXXXXXXXXXXXXXXXXXXX') 
                  or die('Could not select a database.');
               
              // Example query: (TOP 10 equal LIMIT 0,10 in MySQL)
              $SQL = "SELECT TOP 1 * FROM table where isHex is null or isHex = '0' ORDER BY smsdt desc";
              //$SQL = "SELECT * FROM GPRSIN where id = '1586'";
              //echo $SQL; 
              //die($SQL);
              // Execute query:
              $result = mssql_query($SQL) 
                  or die('A error occured: ' . mysql_error());
               

              // Fetch rows:
              while ($Row = mssql_fetch_assoc($result)) {
               
                  //print $Row['smsmsg'] . "\n";
                  $datastring       = $Row['smsmsg'];

do you really have four different data definitions stored in one table or is this an exercise to see how you would solve a made up problem?

 

any performance problem is due to the queries and due to the number of overall queries. you would want to make sure that each query is as efficient as possible and that you run a minimum of different queries.

 

are the queries that are using LIKE '%some_value.%' actually trying to find exact matches? if so, you should be using = comparisons.

 

will the queries using TOP 1 only match at most one row in the table or can they match multiple rows but you only want one?

 

do you have indexes set up in the database tables so that finding information would be as efficient as possible?

 

 

so, how would i (probably) approach doing this. i would query for all your main data at once, loop over each row and split up the four different datastring formats to come up with one common set of data for each existing row, without performing any of the other select queries. insert this now, split up, common set of data into a new table. to retrieve any related data, just JOIN this new table with your TRIANGULATION, ROAD, and account tables.
