Select from multiple tables for search filter from single text field

I need a text field "keywords" to deliver results from multiple tables. Here is the Query so far which is throwing errors:

SELECT UserArtistName,UserBandName, UserBusinessName, UserInfluences AS 'who' FROM users UNION SELECT AlbumTitle, AlbumTrack1, AlbumTrack2, AlbumTrack3, AlbumTrack4, AlbumTrack5, AlbumTrack6, AlbumTrack7, AlbumTrack8, AlbumTrack9, AlbumTrack10, AlbumTrack11, AlbumTrack12, AlbumTrack13, AlbumTrack14, AlbumTrack15, AlbumTrack16, AlbumTrack17, AlbumTrack18, AlbumTrack19, AlbumTrack20 AS 'what' FROM discography WHERE ('who' LIKE ? OR 'what' LIKE ?) OR UserGenreID = ? OR UserState = ?
$rsResults->bindParam("cl", "".(isset($_POST['keyword'])?$_POST['keyword']:"") ."", "-1"); //paramKeywords
$rsResults->bindParam("i", "".(isset($_POST['genre'])?$_POST['genre']:"") ."", "-1"); //paramGenre
$rsResults->bindParam("s", "".(isset($_POST['state'])?$_POST['state']:"") ."", "-1"); //paramState

You would have to pass the parameter twice like:

SELECT UserArtistName,UserBandName, UserBusinessName, UserInfluences AS 'who' FROM users UNION SELECT AlbumTitle, AlbumTrack1, AlbumTrack2, AlbumTrack3, AlbumTrack4, AlbumTrack5, AlbumTrack6, AlbumTrack7, AlbumTrack8, AlbumTrack9, AlbumTrack10, AlbumTrack11, AlbumTrack12, AlbumTrack13, AlbumTrack14, AlbumTrack15, AlbumTrack16, AlbumTrack17, AlbumTrack18, AlbumTrack19, AlbumTrack20 AS 'what' FROM discography WHERE ('who' LIKE ? OR 'what' LIKE ?) OR UserGenreID = ? OR UserState = ?
$rsResults->bindParam("c", "".(isset($_POST['keyword'])?$_POST['keyword']:"") ."", "-1"); //paramKeywords
$rsResults->bindParam("c", "".(isset($_POST['keyword'])?$_POST['keyword']:"") ."", "-1"); //paramSecondKeywords
$rsResults->bindParam("i", "".(isset($_POST['genre'])?$_POST['genre']:"") ."", "-1"); //paramGenre
$rsResults->bindParam("s", "".(isset($_POST['state'])?$_POST['state']:"") ."", "-1"); //paramState

Error in SQL syntax

You should be able to turn on debugging in your rsobj.php file to see the full error. It could be a typo in a column name or something of that nature.

How do I do that? Do the AS statements look correct to you? I read somewhere that if the columns contain spaces you should use [ ] or " "

I'll run the query directly in phpMyAdmin but would be good to be able to turn on debugging in rsobj

I don't know what you are trying to do... a UNION SELECT should have the same columns as the initial select... so the entire query seems odd to me.

I'm pretty sure you don't want a UNION SELECT at all. In some cases it makes more sense to use two Recordsets.

Basically I am trying to use 1 text field on the search page to filter the results from 2 tables and 11 different columns

Are the two tables related? I'd probably use two different recordsets. Then each recordset can filter with the same text field.

The here clause would have the column and parameter repeated for each column you were searching against.

What about an INNER JOIN?
SELECT UserArtistName, UserBandName, UserBusinessName, UserState, UserGenreID, UserInfluences AlbumTitle, AlbumTrack1, AlbumTrack2, AlbumTrack3, AlbumTrack4, AlbumTrack5, AlbumTrack6, AlbumTrack7, AlbumTrack8, AlbumTrack9, AlbumTrack10, AlbumTrack11, AlbumTrack12, AlbumTrack13, AlbumTrack14, AlbumTrack15, AlbumTrack16, AlbumTrack17, AlbumTrack18, AlbumTrack19, AlbumTrack20 AS 'what' FROM users INNER JOIN discography ON AlbumUserID = UserID WHERE ('what' LIKE ?) OR UserGenreID = ? OR UserState = ? OR UserBusinessName LIKE ?");
$rsResults->bindParam("c", "".(isset($_POST['keyword'])?$_POST['keyword']:"") ."", "-1"); //paramKeywords
$rsResults->bindParam("i", "".(isset($_POST['genre'])?$_POST['genre']:"") ."", "-1"); //paramGenre
$rsResults->bindParam("s", "".(isset($_POST['state'])?$_POST['state']:"") ."", "-1"); //paramState
$rsResults->bindParam("cl", "".(isset($_POST['business'])?$_POST['business']:"") ."", "-1"); //paramBusinessName



How do you turn on debugging in rsobj?

If you have the latest version just look in the file for where it has Debug=false and change it to true;

Yes an INNER JOIN makes more sense.

SELECT UserArtistName, UserBandName, UserBusinessName, UserState, UserGenreID, UserInfluences AlbumTitle, AlbumTrack1, AlbumTrack2, AlbumTrack3, AlbumTrack4, AlbumTrack5, AlbumTrack6, AlbumTrack7, AlbumTrack8, AlbumTrack9, AlbumTrack10, AlbumTrack11, AlbumTrack12, AlbumTrack13, AlbumTrack14, AlbumTrack15, AlbumTrack16, AlbumTrack17, AlbumTrack18, AlbumTrack19, AlbumTrack20 AS 'what' FROM users INNER JOIN discography ON AlbumUserID = UserID WHERE AlbumTrack1 LIKE ? OR AlbumTrack2 LIKE ? OR AlbumTrack3 LIKE ? OR AlbumTrack4 LIKE ? OR AlbumTrack5 LIKE ? OR AlbumTrack6 LIKE ? OR AlbumTrack7 LIKE ? OR AlbumTrack8 LIKE ? OR AlbumTrack9 LIKE ? OR UserGenreID = ? OR UserState = ? OR UserBusinessName LIKE ?");
$rsResults->bindParam("c", "".(isset($_POST['keyword'])?$_POST['keyword']:"") ."", "-1"); //paramAlbumTrack1
$rsResults->bindParam("c", "".(isset($_POST['keyword'])?$_POST['keyword']:"") ."", "-1"); //paramAlbumTrack2
$rsResults->bindParam("c", "".(isset($_POST['keyword'])?$_POST['keyword']:"") ."", "-1"); //paramAlbumTrack3
$rsResults->bindParam("c", "".(isset($_POST['keyword'])?$_POST['keyword']:"") ."", "-1"); //paramAlbumTrack4
$rsResults->bindParam("c", "".(isset($_POST['keyword'])?$_POST['keyword']:"") ."", "-1"); //paramAlbumTrack5
$rsResults->bindParam("c", "".(isset($_POST['keyword'])?$_POST['keyword']:"") ."", "-1"); //paramAlbumTrack6
$rsResults->bindParam("c", "".(isset($_POST['keyword'])?$_POST['keyword']:"") ."", "-1"); //paramAlbumTrack7
$rsResults->bindParam("c", "".(isset($_POST['keyword'])?$_POST['keyword']:"") ."", "-1"); //paramAlbumTrack8
$rsResults->bindParam("c", "".(isset($_POST['keyword'])?$_POST['keyword']:"") ."", "-1"); //paramAlbumTrack9
$rsResults->bindParam("i", "".(isset($_POST['genre'])?$_POST['genre']:"") ."", "-1"); //paramGenre
$rsResults->bindParam("s", "".(isset($_POST['state'])?$_POST['state']:"") ."", "-1"); //paramState
$rsResults->bindParam("cl", "".(isset($_POST['business'])?$_POST['business']:"") ."", "-1"); //paramBusinessName
