I have join 5 tables how to use inner join query for joining five tables in c# using ms access database? this is my code try { OleDbConnection conn = new OleDbConnection(); conn.ConnectionString = @"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=D:\BS(CS)-6A\BS(CS)-6A\Database Managment System\Student Managment Project\School_Database\School_Managment_System.accdb; Persist Security Info=False;"; conn.Open(); OleDbCommand cmd = new OleDbCommand(); cmd.Connection = conn; // string query = "select s.std_id, s.std_name, s.std_fname, s.std_phone, s.std_address, f.fee_paid, f.balance, f.fee_month, f.fee_year from std_info s join std_fees f on s.std_id = f.std_id"; string query = @"select *from (std_info inner join std_fees on std_info.std_id = std_fees.std_id), (inner join fees on fees.fee_id = std_fees.fee_id),(inner join class on class.class_id = fees.class_id)"; cmd.CommandText = query; OleDbDataAdapter da = new OleDbDataAdapter(cmd); DataTable dt = new DataTable(); da.Fill(dt); dataGrid1.DataSource = dt; conn.Close(); } catch (Exception ex) { MessageBox.Show("Error" + ex); }

FROM payment INNER JOIN income,bank_dep


You can have more tables in FROM, like: FROM payment,income,bank_dep, but you can't have other than one single table after JOIN, and you have two. And you never can have an operation like a=b=c, but you have You need to split the statement across multiple joins:
SQL
SELECT payment.indate,payment.opening_balance,payment.purpose,payment.amount,income.indate,income.opening_balance,income.purpose,income.amount,bank_dep.indate,bank_dep.balance_opening,bank_dep.bank,bank_dep.amount 
FROM (payment 
INNER JOIN income ON payment.indate=income.indate)
INNER JOIN bank_dep ON income.indate=bank_dep.indate

it gives an error "syntax error(missing operator) in query expression 'payment.indate=income.indate INNER JOIN bank_dep on income.indate=bank_dep.indate"

Sorry, Access is non-standard, it requires some parenthesis. See updated query.
