Firebird提交在Java应用程序中不起作用

Question

I'm using a procedure to insert data in my firebird database. This procedure is called in a while command because there is no limit for how many items I can insert, for example:

while (there's itens) {
    query("select * from procedure_insert(id,desc,etc);");
}

This doesn't work, after I finish my insertion not a single item is inserted in the database. My procedure works fine there's no doubt, I believe it's a problem with the class I use to query and commit

Here is my code:

Persistence class:

public class Persistence {

    public static Connection con = Conn.getConn();
    public static Statement stm  = null;

    public static void Conn(){
        try {
            stm  = con.createStatement();
        } catch (SQLException e) {
            //
        }
    }

    public static void Insert(String query) {

        try {
            stm.execute(query);
        } catch (SQLException e) {
            //
        } 
    }

    public static void Commit(){
        try {
            con.commit();
    } catch (SQLException e) {
        //
    }
}

Insert:

while(rs.next()){

    Items item = new Items();
    item.setItem_data(rs.getString("ZPED_ITEM_DATA"));
    item.setItem_desconto(rs.getDouble("ZPED_ITEM_VALOR_V") - rs.getDouble("ZPED_ITEM_DESCONTO"));
    item.setItem_produto(rs.getInt("ZPED_ITEM_PRODUTO"));
    item.setItem_qtd(rs.getDouble("ZPED_ITEM_QTD"));
    item.setItem_valor_v(rs.getDouble("ZPED_ITEM_VALOR_V"));
    item.setPed_cod(rs.getInt("ZPED_COD"));
    ////////////////////////////////////////////////////////////////
    Persistence.Insert("SELECT * FROM PEDIDOS_PROC("+a+","+b+","+p.get(0).getCod_n()+",'"+p.get(0).getData()+"',55,"+item.getItem_produto()+",0,"+item.getItem_qtd()+","+item.getItem_valor_v()+",'A',2);");
    Persistence.Commit();
}

thank you!

Answer 1

is PEDIDOS_PROC selectable procedure? If no you must to execute it

execute procedure PEDIDOS_PROC(params...)
