我整晚都在尝试这个
String querystate = " insert into provincias (Paises_idPais, Provincia, Abreviatura, Km2, Capital, `Ciudad mas grande`)"
+ " values (?, ?, ?, ?, ?, ?)";
PreparedStatement preparedStmt;
preparedStmt = conn.prepareStatement(querystate);
preparedStmt.setInt(1, cID);
preparedStmt.setString(2, sName);
preparedStmt.setString(3, sAbbr);
preparedStmt.setInt(4, sArea);
preparedStmt.setString(5, sCapital);
preparedStmt.setString(6, sLargest_city);
preparedStmt.execute();
执行此操作时,它会给出一个如下所示的查询:
insert into provincias(Paises_idPais, Provincia, Abreviatura, Km2, Capital, `Ciudad mas grande`) values (1, `a`, `a`, 1, `a`, `a`)
Aaaaaa它给了我关于字段列表的错误
"未知列' a'在'字段列表'
这是我使用e.printStackTrace();
时得到的错误com.mysql.jdbc.JDBC42PreparedStatement@202b0582: insert into provincias (Paises_idPais, Provincia, Abreviatura, Km2, Capital, `Ciudad mas grande`) values (1, 'a', 'a', 1, 'a', 'a')
