not able to compare & fetch data from table using where clause

[rahullko05]

Hi,

i am building a small forum site as my final year project & stuck in a very trivial problem.

I have a table which are varchar type of data & i am trying to fetch data from table based on some condition.

$query = 'select reply_Id, post_Id, replied_by, reply, date_of_reply from reply_info where reply_info.post _Id ='. $x;

as $x='pi_1';

here $x has string value & post_Id in table has varchar value & has the same value (for that column in table) as given to $x, but still this query execution is failing. it returns false for result.

Now if i dont give any where clause query fetches all the rows of table. I tried this to confirm if connection to data base is working fine.

this is really urgent..i have already wasted an hour in this :-(

thanks in advance.

There's nothing that sticks out at me, other than that IDs are generally stored as integers. Are you positive it's a VARCHAR?

When you're developing something, you should be debugging it. So, use mysql_error() if a query fails, to see why it failed.

$query = "SELECT * FROM `tbl1` WHERE 1";
$query_result = mysql_query( $query ) or die ( mysql_error() );

As soon as the query is stored in $query_result, if there's an error, your page will die with the cause of the error displayed, e.g. 'tbl1 doesn't exist'.
