我一直试图获得一段代码，该代码使用带参数的spring和oracle存储过程，但一直发现它很难运行。指定的存储过程旨在期望三个参数，但在出现的错误中它预期为四个。第四个参数是要返回的游标。
这是我的Oracle（9i）包规范：
CREATE OR REPLACE PACKAGE pkg_data_load AS
procedure sp_atm_withdrawal(p_catermid IN VARCHAR2,
p_start_date IN VARCHAR2,p_end_date IN VARCHAR2,p_out out sys_refcursor);
END;
以下是包体：
CREATE OR REPLACE PACKAGE BODY pkg_data_load
AS
procedure sp_atm_withdrawal
(
p_catermid IN VARCHAR2,
p_start_date IN VARCHAR2,
p_end_date IN VARCHAR2,
p_out out sys_refcursor
) as
v_start_date date := to_date(p_start_date,'yyyy/mm/dd');
v_end_date date := to_date(p_end_date,'yyyy/mm/dd');
begin
open p_out for select
b.nam_branch BRANCH_NAME
, a.bcode brn_Code
, a.acct_no Acct_no
from table a, table b where b.cod_Cc_brn= a.cod_org_brn
and a.cod_reply=0
and b.flg_mnt_status='A'
and a.cod_proc not in ( 312000, 382000, 311000, 381000)
and a.cod_txn_literal<>'SCD'
and a.ca_term_id in (
select ca_term_id from tablec where flg_mnt_status='A')
and a.dat_post_stl between v_start_date and v_end_date
and a.ca_term_id = p_catermid;
end sp_atm_withdrawal;
END pkg_data_load;
以下是我的程序类的片段
public class AtmStoredProcedures extends StoredProcedure {
public AtmStoredProcedures(JdbcTemplate jdbcTemplate, String procedure)
{
super(jdbcTemplate,procedure);
AtmRowMapper rowMapper = new AtmRowMapper();
declareParameter(new SqlOutParameter("sys_refcursor",OracleTypes.CURSOR, rowMapper));
declareParameter(new SqlParameter("branch", Types.VARCHAR));
declareParameter(new SqlParameter("startDate", Types.VARCHAR));
declareParameter(new SqlParameter("endDate", Types.VARCHAR));
compile();
}
public Map getCashWithdrawals(String branch, String startDate, String endDate)
{
Map inParam = new HashMap();
inParam.put("branch", branch);
inParam.put("startDate", startDate);
inParam.put("endDate", endDate);
Map out = execute(inParam); // Call on parent class
return out;
}
}
以下是我的DAO实施方法
public List<Atm> loadWithdrawal(String branch, String startDate, String endDate) {
if (this.jdbcTemplate == null) {
System.out.print("JDBC TEMPLATE IS NULL");
}
List<Atm> withdrawals = null;
try
{
AtmStoredProcedures st = new AtmStoredProcedures(jdbcTemplate,"pkg_data_load.sp_atm_withdrawal");
Map results = st.getCashWithdrawals(branch, startDate, endDate);
withdrawals = (List<Atm>) results.get("sys_refcursor");
} catch (DataAccessException ex) {
System.out.print(ex.getMessage());
}
return withdrawals;
}
成功完成后，我在运行时会收到以下错误
CallableStatementCallback; bad SQL grammar
[{call pkg_data_load.sp_atm_withdrawal(?, ?, ?, ?)}];
nested exception is java.sql.SQLException:
ORA-06550: line 1, column 7: PLS-00306: wrong number or
types of arguments in call to 'SP_ATM_WITHDRAWAL'ORA-06550:

答案 0 :(得分：4)
您对declareParameter（）的调用必须与Oracle存储过程的顺序相同。试试这个：
declareParameter(new SqlParameter("branch", Types.VARCHAR));
declareParameter(new SqlParameter("startDate", Types.VARCHAR));
declareParameter(new SqlParameter("endDate", Types.VARCHAR));
declareParameter(new SqlOutParameter("sys_refcursor",OracleTypes.CURSOR, rowMapper));
