RECORD类型与JDBC不兼容是真的吗?司机正在使用的是OJDBC6.jar
Java代码:
dbStrategy.openConnection();
WrappedConnectionJDK6 wrapped = (WrappedConnectionJDK6) dbStrategy.getConnection();
OracleConnection oracleConnection = (OracleConnection) wrapped.getUnderlyingConnection();
CallableStatement callableStatement = oracleConnection.prepareCall("{call XXX_Info_Utl_Pkg.get_order_admin(?,?,?,?,?)}");
callableStatement.setInt(1, Integer.parseInt(orderNumber));
callableStatement.registerOutParameter(2, OracleTypes.ARRAY, "XXX_INFO_UTL_PKG.SEAGRS_ORDER_REC");
callableStatement.registerOutParameter(3, OracleTypes.NUMBER);
callableStatement.registerOutParameter(4, OracleTypes.VARCHAR);
callableStatement.registerOutParameter(5, OracleTypes.NUMBER);
和Oracle代码:
PROCEDURE get_order_admin(
p_order_num_in IN NUMBER,
p_order_admin_out OUT XXX_info_utl_pkg.seagrs_order_rec,
p_error_code_out OUT PLS_INTEGER,
p_error_msg_out OUT VARCHAR2,
p_ret_status_out OUT PLS_INTEGER);
TYPE seagrs_order_rec
IS
record
(
order_admin VARCHAR2(10),
contact_name VARCHAR2(50),
contact_email_addr VARCHAR2(100),
contact_phone_num VARCHAR2(30));
我面临的错误是 -
例外:名称模式无效:XXX_INFO_UTL_PKG.SEAGRS_ORDER_REC
答案 0 :(得分:3)
记录类型与JDBC驱动程序不兼容:
Oracle JDBC驱动程序支持调用是不可行的 PL / SQL RECORD,BOOLEAN或表的参数或返回值 非标量元素类型。但是,Oracle JDBC驱动程序支持 PL / SQL索引 - 标量元素类型表。
答案 1 :(得分:2)
虽然您无法直接使用JDBC来获取PL / SQL RECORD类型,但您可以编写一个匿名PL / SQL块并将该记录返回到本地变量中,然后您可以按如下方式分解其各个属性:
DECLARE
rec XXX_info_utl_pkg.seagrs_order_rec;
BEGIN
get_order_admin(?, rec, ?, ?, ?);
? := rec.order_admin;
? := rec.contact_name;
? := rec.contact_email_addr;
? := rec.contact_phone_num;
END;
您现在可以使用以下JDBC代码来调用该过程:
try (CallableStatement s = con.prepareCall(" ... previous PL/SQL block ...")) {
s.setInt(1, Integer.parseInt(orderNumber));
// Ordinary out parameters
s.registerOutParameter(2, Types.NUMBER);
s.registerOutParameter(3, Types.VARCHAR);
s.registerOutParameter(4, Types.NUMBER);
// Out parameters from your decomposed record
s.registerOutParameter(5, Types.VARCHAR);
s.registerOutParameter(6, Types.VARCHAR);
s.registerOutParameter(7, Types.VARCHAR);
s.registerOutParameter(8, Types.VARCHAR);
s.execute();
// Now, retrieve all the out parameters
}
I have recently blogged about this technique more in detail。博客文章还包含有关如何为所有具有记录IN / OUT参数的函数/过程自动生成匿名PL / SQL块的说明。
