Here my code:

 //connect data base and select the table....
 ....
 //query
 $SQuery = "select len,pdfdata from PDFTable where nid = 34"
 // the entry exist
 // fetch the only row
 
 $row = mssql_fecth_row($SQuery);
 
 // ok!!
 
 header("Content-type: application/pdf");
 header("Content-lenght: ".$row[0]);
 print $row[1];

 The script launch the PDF program, but it remains in the list of process getting the 100% of the CPU.
 I think that the data are not completed, due to when i delete the headers lines, the binary code appears into the browser, but is not complete!!!, i think only it show 4096 bytes of the file instead of the 65470 of its real lenght.....

I did the same test using ASP .NET and the code, similar from the above works fine, but i need make it in PHP.
 Any limitations?, any wrong in the php code? or maybe this language script is not ready to work with MSSQL Server?.

Thank´s in advantage.

It's a round about way of fixing it, but others have solved this problem using the DUMPFILE flag in their query.

For your query it would look like:

$SQuery="SELECT len,pdfdata from PDFTable WHERE nid=34 DUMPFILE \"/tmp/temp.pdf\""

Then read in the file and display it.

By the way, if the PDF is 65470 bytes, I assume you are using MEDIUM BLOBs or larger?
