使用 java 以 table 对象作为输入调用 oracle 存储过程

Question

我尝试使用 4 个参数 1 作为自定义类型的输入调用 oracle 存储过程 table 并得到以下错误 PriceInBundle_Input_Table 是一个有两个元素的对象材料编号 nvarchar2(22)， BundleNumber nvarchar2(22)

java.sql.SQLException: ORA-03115: unsupported network datatype or representation

我尝试使用以下 java 代码进行呼叫

import com.wincash.test.config.DBConnection;

import oracle.jdbc.OracleCallableStatement;
import oracle.sql.ARRAY;
import oracle.sql.ArrayDescriptor;

public class PriceInBundle {
    private static Logger logger= Logger.getLogger(PriceInBundle.class);
    private static Connection conn=null;
    private static OracleCallableStatement callStatement=null;

    public Boolean getPriceInBundle() {
        Boolean rs=Boolean.FALSE;
        conn=DBConnection.getConnection();
        try {
            Object [] table= new Object[2];

            ArrayDescriptor priceInBundleTable= ArrayDescriptor.createDescriptor("PRICEINBUNDLE_INPUT_TABLE", conn);
            ARRAY priceInTable= new ARRAY(priceInBundleTable, conn, table);
            callStatement=(OracleCallableStatement)conn.prepareCall("{call GET_PRICE_IN_BUNDLE(?,?,?,?)}");
            callStatement.setARRAY(1, priceInTable);
            callStatement.registerOutParameter(2, java.sql.Types.ARRAY);
            callStatement.registerOutParameter(3, java.sql.Types.NUMERIC);
            callStatement.registerOutParameter(4, java.sql.Types.VARCHAR);

            rs=callStatement.execute();
        } catch (SQLException e) {
//          logger.info(e.getMessage());
            e.printStackTrace();
        }finally {
            try {
                conn.close();
                callStatement.close();
            } catch (SQLException e) {
                logger.info(e.getMessage());
            }

        }
        return rs;
    }
}

请大家多多支持

Answer 1

我找到了解决方案只需将 oracle 自定义类型添加到输出参数，如以下代码 将此代码更改为

callStatement.registerOutParameter(2, java.sql.Types.ARRAY);

到

callStatement.registerOutParameter(2, java.sql.Types.ARRAY,"PRICEINBUNDLE_OUTPUT_TABLE");

由于 Marmite Bomber 的评论
