hi guys, stmt=conn.prepareStatement("select * from klasseFaecher"+" where Klasse like'"+klasse+"'"+"where '"+kfach+"'=ja"); this statement displays a "missing operator" error... please help....it urgent vikas
to group two "where" clauses like that you really need a relation; I assume you mean "AND" in this case. You should also be careful to quote all text constants but not column names (is ja really a column name or does kfach contain the column name and 'ja' the value?), and make sure there are spaces round each keyword. A rewritten version might therefore be:
I also strongly recommend that you get in the habit of specifying the columns to return in your SQL. It makes your software much more robust if the order of the columns in the table changes, or if new columns are added for other purposes. It also makes it much easier for reviewers and other helpers to understand
