WARN/System.err(7227): android.database.sqlite.SQLiteException: near "(": syntax error: , while compiling: update exam set ( examdetails=?, subchawise=?, examtype=?, noquestion=?, marks=?, subject_id=?, chapter_id=? ) where exam_id ='1'

Answer 1

This is a standard way of doing it:

String query = "UPDATE exam SET examdetails = ?, subchawise = ?, examtype = ?, noquestion = ?, marks = ?, subject_id = ?, chapter_id = ? WHERE exam_id = ?";

String[] params = new String[]{owq.getExamDetails(), owq.getSubChapwise(), owq.getExamType(), owq.getNoOfQuestion(), owq.getMarks(), String.valueOf(owq.getSubjectId()), String.valueOf(owq.getChapterId()), id};

db.rawQuery(query, params);
