我在Oracle中有一个存储过程，如下所示。
create or replace TYPE T_EMP_OBJ AS OBJECT (Name varchar2(20), Age CHAR(3 CHAR));
create or replace type T_EMP_REC as table of T_EMP_OBJ;
create or replace PROCEDURE P_EMP (I_NAV_REC IN T_INAV_REC, p_out OUT MY_TYPES_PKG.REFCURSOR)
AS ...
END P_EMP;
我从java调用该过程。我的代码是，
StructDescriptor structDesc = new StructDescriptor("T_EMP_OBJ", oracleConnection);
ArrayDescriptor arrayDesc2 = new ArrayDescriptor("T_EMP_REC", oracleConnection);
Object[] objType = new Object[2];
objType[0] = new String("AAA");
objType[1] = new String("25");
STRUCT struct = new STRUCT(structDesc, oracleConnection, objType);
STRUCT[] structs = new STRUCT[1];
structs[0] = struct;
oracle.sql.ARRAY array = new oracle.sql.ARRAY(arrayDesc2, oracleConnection, structs);
OracleCallableStatement statement = (OracleCallableStatement) oracleConnection.prepareCall("CALL P_EMP(?,?)");
statement.setArray(1, array);
statement.registerOutParameter(2, oracle.jdbc.OracleTypes.CURSOR);
statement.execute();
ResultSet results = ((OracleCallableStatement) statement).getCursor(2);
while (results.next()) {
logger.info("NAME==>"+results.getString(1));
logger.info("AGE===>"+results.getString(2));
}
虽然我收到记录，但该值为空。这意味着如果输出是2行，则while条件执行并打印null。在SQL Developer中它运行正常。提前谢谢。
