java sql insert preparedstatment error - 


string sql = " insert `tblservice` (`serviceid`,`accountid`, `kind`, `description`, `price`, "         + "`quantity`, `total`, `dateandtime`) values (null, ?, ?, ?, ?, ?, ?, ?)"; preparedstatement pstm = conn.preparestatement(sql); pstm.setint(1, this.accountid); pstm.setstring(2, "" + selectionbox.getselecteditem()); pstm.setstring(3, desc); pstm.setfloat(4, float.parsefloat(pricetf.gettext())); pstm.setfloat(5, float.parsefloat(quantitytf.gettext())); pstm.setfloat(6, this.gettotal()); pstm.setdate(7, dateadded);  pstm.executeupdate();

error

com.mysql.jdbc.exceptions.jdbc4.mysqlsyntaxerrorexception: have error in sql syntax; check manual corresponds mariadb server version right syntax use near '?, ?, ?, ?, ?, ?, ?)' @ line 1

instead of make null in query values (null, ...) use setnull example :

pstm.setnull(1, java.sql.types.integer);

it take type, of field, in example consider java.sql.types.integer can java.sql.types.varchar or sql type

so query should :

string sql = "insert tblservice (serviceid, accountid, kind, description,                 price, quantity, total, dateandtime)                 values (?, ?, ?, ?, ?, ?, ?, ?)";  preparedstatement pstm = conn.preparestatement(sql); pstm.setnull(1, java.sql.types.integer); pstm.setint(2, this.accountid); ....
