Question

Hey all. I think I have a logic error in my qry. The output is correct but in triplets. I’ve been staring at this for a long time and not seeing it. Can someone shed some light on this? Thanks!!

Also wanted to add this info as well.

• $userid = 1
• $UserIDAList = (1,1,6)
• $UserIDBList = (2,3,1)

PHP-Code:

$result  = mysql_query("SELECT TBL_ContactsList.ContactID, TBL_ContactName.FirstName FROM TBL_ContactsList, TBL_ContactName WHERE ((TBL_ContactName.NameID != $userid) AND (TBL_ContactsList.ContactID != $userid)) AND ((TBL_ContactName.NameID IN ($UserIDAList) OR TBL_ContactName.NameID IN $UserIDBList)))");

while ($row = mysql_fetch_array($result, MYSQL_NUM)) {
    printf ("ID: %s  Name: %s", $row[0], $row[1]);
    echo "<br/>";
}

Only the SQL-Query (readability):

SELECT TBL_ContactsList.ContactID, TBL_ContactName.FirstName 
FROM TBL_ContactsList, TBL_ContactName 
WHERE ((TBL_ContactName.NameID != $userid) AND (TBL_ContactsList.ContactID != $userid)) 
AND ((TBL_ContactName.NameID IN ($UserIDAList) OR TBL_ContactName.NameID IN $UserIDBList)))

Output:

ID: 2 Name: Joe
ID: 3 Name: Joe
ID: 4 Name: Joe
ID: 2 Name: Jimbo
ID: 3 Name: Jimbo
ID: 4 Name: Jimbo
ID: 2 Name: Mike
ID: 3 Name: Mike

EDIT: Here is what I ended up using. (can’t figure out indent on here.)

But now I am missing an entry from the db.

$result = mysql_query("
SELECT cl.ContactID, cn.FirstName
FROM TBL_ContactName AS cn
INNER JOIN TBL_ContactsList AS cl
ON cl.ContactID = cn.NameID
WHERE
cn.NameID != $userid
AND (
cn.NameID IN ($UserIDBList) OR cn.NameID IN ($UserIDAList)
)
");

The output looks like this.
ID: 2 Name: Joe
ID: 3 Name: Jimbo

But when I put LEFT JOIN I get this. Close but still missing ID.
ID: 2 Name: Joe
ID: 3 Name: Jimbo
ID: Name: Mike

Any ideas?? THanks!

If I got your SQL structure correctly, changing SQL like this should probably fix it. At least it’s a proper usage.

$result=mysql_query("SELECT cl.ContactID, cn.FirstName FROM TBL_ContactsList cl INNER JOIN TBL_ContactName cn ON cn.NameID=cl.ContactID WHERE cn.NameID != $userid AND (CN.NameID IN ($UserIDAList) OR CL.NameID IN ($UserIDBList))");
