我有两种方法,一种是工作,另一种不适用于插入查询
// this one fails
public void product(String product, String quantity, String price,
String date) throws SQLException {
try {
statement.execute("INSERT INTO product (productn,quantity,price,date) VALUES ('" + product + "','" + quantity + "','" + price + "','" + date + "')");
} catch (Exception e) {
System.out.println(e.getMessage());
}
}
// this one works
public void customer(String name, String q, String p, String pro)
throws SQLException {
try {
statement.execute("INSERT INTO Customer (name,price,product,quantity) VALUES ('" + name + "','" + q + "','" + p + "','" + pro + "')");
} catch (Exception e) {
System.out.println("problem in Customer insert !");
}
}
一个正常工作的方法意味着它将数据插入表中,但另一个方法产生以下错误:
[Microsoft][ODBC Microsoft Access Driver] Syntax error in INSERT INTO statement

您将有更多机会以这种方式执行此操作,就像您可以更好地检查值的完整性。
private static final String insert = "INSERT INTO product (productn,quantity,price,date) VALUES ('"+?+"','"+?+"','"+?+"','"+?+"')";
statement.clearParameters();
statement.set"Type_of_the_value"(1, productn) ;
statement.set"Type_of_the_value"(2, quantity) ;
statement.set"Type_of_the_value"(3, price) ;
statement.set"Type_of_the_value"(4, date) ;
statement.executeUpdate() ;

试试这个:
INSERT INTO product ([productn],[quantity],[price],[date]) VALUES ('" + product + "','" + quantity + "','" + price + "','" + date + "')
