内部错误：映像是集合映像，与Oracle一起使用的是ADT

问题描述

|| 我正在尝试使用spring-jdbc在oracle数据库上调用存储的函数。 这是我尝试调用的存储函数：

FUNCTION GET_RESOURCE_LIST RETURN RESOURCE_TAB;

接下来是resource_tab的定义

TYPE RESOURCE_TAB AS TABLE OF TRESOURCE;

接下来是tresource的定义

TYPE TRESOURCE AS OBJECT(
RESOURCE_ID NUMBER(10,0),RESOURCE_NAME VARCHAR2(100)
)

调用代码

final SimpleJdbcCall call = new SimpleJdbcCall(idmJdbcTemplate).withFunctionName(\"get_resource_list\").declareParameters(new sqlOutParameter(
        \"RETURN\",OracleTypes.STRUCT,\"RESOURCE_TAB\",new sqlReturnType() {

          @Override
          public Object getTypeValue(CallableStatement cs,int paramIndex,int sqlType,String typeName) throws sqlException {
            final Struct s = (Struct)cs.getobject(paramIndex);
            final Object[] attr = s.getAttributes();
            return attr[1];
          }             
        }));

call.compile();
final Collection<String> resources = call.executeFunction(Collection.class);

最后是我收到的堆栈跟踪：

解决方法

我有同样的问题，我花了一天的时间来解决它。 考虑错误“图像是集合图像”，而不是

OracleTypes.STRUCT

必须是

OracleTypes.ARRAY

。 关于您的getTypeValue（...）方法，我不能说是对还是不对，但是我将展示如何解析结果集（也许是这样，请以其他方式写出来）：

@Override
public Object getTypeValue(CallableStatement cs,int paramIndex,int sqlType,String typeName) throws SQLException {

    ARRAY struct = (ARRAY) cs.getObject(paramIndex);

    ResultSet rs = struct.getResultSet();

    while (rs.next()) {
        Object rowIndex = rs.getObject(1);
        oracle.sql.STRUCT row = (oracle.sql.STRUCT) rs.getObject(2);
        if (row != null) {
            Object[] cols = row.getAttributes();
            System.out.print(rowIndex + \": \");
            for (Object col : cols) {
                System.out.print(col + \" \");
            }
            System.out.println();
        }
    }

    return \"construct your data structure above and return here\";
}

另一种方法是

    @Override
public Object getTypeValue(CallableStatement cs,String typeName) throws SQLException {

    ARRAY array = (ARRAY) cs.getObject(paramIndex);

    Object[] rows = (Object[])array.getArray();

    for(Object row : rows){
        Object[] cols = ((oracle.sql.STRUCT)row).getAttributes();
        for (Object col : cols) {
            System.out.print(col + \" \");
        }
        System.out.println();

    }

    return \"construct your data structure above and return here\";
}

    ,问题在于输出参数的声明

final SimpleJdbcCall call = new SimpleJdbcCall(idmJdbcTemplate).withFunctionName(\"get_resource_list\").declareParameters(new SqlOutParameter(
    \"RETURN\",OracleTypes.STRUCT,\"RESOURCE_TAB\",new SqlReturnType() <etc>

返回类型（

TYPE RESOURCE_TAB AS TABLE OF TRESOURCE

）不是

OracleTypes.STRUCT

（为对象类型保留），而是an6ѭ。
