mysql_query error

I've got a query that I build in PHP and then call mysql_query on. The link to the database is active and working. But it gives me a SQL error: "You have an error in your SQL syntax near '' at line 1".

Problem is if I echo the query to the page and copy and paste the query into the mySQLAdmin page then it works just fine.

The query that I run is the following(there are no carraige returns in the text, it is just one long line):

SELECT S_NAME, S_DESCRIPTION, S_START_DATE, S_END_DATE, S_SEND_DATE, P_FIRST_NAME, P_LAST_NAME, P_CONTACT_NO, P_EMAIL, SQ_TEXT, CASE WHEN SQR_TEXT IS NULL THEN SR_TEXT ELSE SQR_TEXT END AS Q_TEXT, S.SURVEY_ID FROM SURVEYS S LEFT JOIN SURVEY_QUESTIONS SQ ON SQ.SURVEY_ID = S.SURVEY_ID LEFT JOIN SURVEY_RESPONSES SR ON SR.SURVEY_QUESTION_ID = SQ.SURVEY_QUESTION_ID LEFT JOIN SURVEY_QUESTION_RESPONSES SQR ON SQR.SURVEY_QUESTION_RESPONSE_ID = SR.SR_TEXT LEFT JOIN RECIPIENT_DETAILS RD ON RD.RECIPIENT_DETAIL_ID = SR.RECIPIENT_DETAIL_ID LEFT JOIN PERSON P ON P.PERSON_ID = RD.PERSON_ID WHERE S.SURVEY_ID = 5

Could anybody maybe know what the problem is.

Thanks

RE: mysql_query error

while (list ($key, $val) = each ($field_list))

//check is value is total_recipients

RE: mysql_query error

do me a favor and try taking the semicolon out after $svid but before the last double quote. I am wondering if something is being misinterpreted due to it.

example

WHERE S.SURVEY_ID = $svid";

not

WHERE S.SURVEY_ID = $svid;";

since I cant actually test it here, I need you to test it for me.

RE: mysql_query error

did that. Still gives the same error. Usually I don't include it but after a bit of RTFM in the php-docs it states that it needs one after the end of a query. So I added it and it made no deference. At the moment it is without it.

RE: mysql_query error

this code follows just below the previous code posted.

$connection = get_db_connection();

$result = mysql_query ( $query, $connection ) or die("Invalid query: " . mysql_error());


The get_db_connection() function connects to the db if the connection has been lost and returns the connection. This function is used in ALL the php files where I query the DB and it works 100%.

RE: mysql_query error

I can be really stupid if I have the time. That query works fine. The value of one of the functions that is in another php file was incorrect and thus the SQL in that function read "WHERE SURVEY_ID = ". The survey_id parameter was empty. Anyway thanks for the trouble. I amaze myself with stupidity sometimes.
