Question

执行 isb.pkg_po_test.get_component 程序，我必须从远程数据库中获取游标。

我们的架构 ISBREPORTER ，我们对架构 ibs 的访问权限有限。但是，在Oracle SQL Plus上，以下内容执行得非常好：

SQL＆GT; var r refcursor
  SQL＆GT; exec isb.pkg_po_test.get_component（15048,6,1,1，to_date（'17 .12.2017'），：r）;
  SQL＆GT;打印;

印刷结果：

    ID PRODUCT_TYPE_ID COMPONENT_ID COMPONENT_NAME                          

     1               1      1012161 some text_1                      
     2               1      1012160 some text_2        
     3               1      1012158 some text_3                               
     4               1        10078 some text_4              
     5               1        10078 some text_5                
     6               1        10040 some text_6                       
     7               1      1012149 some text_7

当我尝试从java代码调用它时，我得到了这个异常：

java.sql.SQLException: ORA-06550: line 1, column 7:
PLS-00201: identifier 'ISB.PKG_PO_TEST must be declared
ORA-06550: line 1, column 7:

以下是我从java中调用它的方法：

public void printCursor(PrintWriter out) {
        Connection ktConnection;
        try {
            ktConnection = ConnectionPool.getConnectionKT();
        } catch (SQLException e) {
            e.printStackTrace();
            return;
        }

        String statement = "{CALL isb.pkg_po_test.get_component(?,?,?,?,?,?)}";
        try {
            CallableStatement call = ktConnection.prepareCall(statement);
            call.setFloat(1, 15048);
            call.setFloat(2, 6);
            call.setFloat(3, 1);
            call.setInt(4, 1);
            call.setDate(5, Date.valueOf("2017-12-17"));
            call.registerOutParameter(6, OracleTypes.CURSOR);

            call.execute();

            ResultSet rs = (ResultSet) call.getObject(6);

            while (rs.next()) {
                String column = rs.getString("COMPONENT_NAME");
                out.print(column); //to test if it is working
            }

        } catch (SQLException e) {
            e.printStackTrace();
        }

    }

从其他模式执行存储过程是否正确？如果不，你能告诉我如何正确处理它吗？

我已阅读其他类似的问题但没有帮助。以下是其中一些：
