How to combine MYSQL query from different table ?


I would like to request an assistant.

I have the following tables :

Table 1 name : transactions
column name : id,ownerid,date,ta,nta,st,tax,seed,debcred,tt

Table 2 name : client_invoices
column name : id,status

Current query :

$res_select = "SELECT id,ownerid,date,ta,nta,st,tax,seed,debcred,tt FROM transactions WHERE date >= $startStamp AND date <= $EndStamp and st != '' order by id";

I would like to combine a condition to the above query as follows :

WHERE transactions.seed  = WHERE client_invoices.status = 1

I have tried the following, but seems not working :

$res_select = "SELECT, transactions.ownerid,, transactions.ta, transactions.nta,,, transactions.seed, transactions.debcred,,
                  FROM transactions
                  RIGHT JOIN client_invoices
                  ON transactions.seed =
                  WHERE ( >= $startStamp AND <= $EndStamp)
                  AND transactions.seed = WHERE client_invoices.status = 1
                  AND != '' ORDER BY";

Appreciates anybody can help me with this query.

Thank you.

Maybe the two WHERE clauses are part of the problem?  MySQL usually creates some kind of error message that you can find if the SELECT query returns FALSE.  Obviously I cannot test this because I do not have your data set, but this is what I might try.
$res_select = "SELECT, transactions.ownerid,, transactions.ta, transactions.nta,,, transactions.seed, transactions.debcred,,
                  FROM transactions
                  RIGHT JOIN client_invoices
                  ON transactions.seed =
                  WHERE ( >= $startStamp AND <= $EndStamp)
                  AND transactions.seed = AND client_invoices.status = 1
                  AND != '' ORDER BY";

While both tables have id, those are not related
