Can't Uncompress Data Stored to MySQL? - El Forum - 12-03-2010
[eluser]Vik[/eluser]
I'm storing a large text file to a MySQL blob field like so:
Code:
$theFile = fopen($thespssDATAfileName, "r+");
$uncompressedDATAFile = addslashes(fread($theFile, filesize($thespssDATAfileName)));
fclose($theFile);
$mysql_query = "UPDATE jobs ";
$mysql_query .= " SET spssDATAfile = (COMPRESS('$uncompressedDATAFile')) ";
$mysql_query .= " WHERE id = '$theJobID'";
$QueryID = mysql_query($mysql_query);All appears to go well, and data which appears to be properly compressed is stored in the correct field.
When I try to uncompress it like this:
Code:
$mysql_query = "SELECT UNCOMPRESS(spssDATAfile) FROM jobs ";
$mysql_query .= " WHERE id = '$theJobID'";
$QueryID = mysql_query($mysql_query);
$theResult = mysql_result($QueryID, 0);...I get a NULL result.
What am I missing?
Thanks in advance to all for any info.

I got the answer - I had to use a field of type longblob rather than of blob.
