PLS-00306：调用＆＃39; SHG_LOAN_QRY＆＃39;中的参数数量或类型错误

Question

从java调用Oracle存储过程时，我收到错误“PLS 00306：调用....时参数的数量或类型错误”

以下是我的java代码：

public ResultSet callShgLoansQry(String comCode,String mainCode,String unitCode,String shgno,String lsrid)
throws SQLException{
Array arr = null;
String query = "{call shg_loans_qry(?,?,?,?,?,?)}";
cstmt = con.prepareCall(query);
cstmt.setString(1, comCode );
cstmt.setString(2, mainCode );
cstmt.setString(3, unitCode);
cstmt.setString(4, shgno);
cstmt.setString(5, lsrid);
cstmt.registerOutParameter(6, OracleTypes.ARRAY,"LOAN_DTS_TAB");
cstmt.execute();
arr = cstmt.getArray(6);
return arr.getResultSet();
}

以下是我的存储过程：

CREATE OR REPLACE PROCEDURE shg_loans_qry(V_COMP IN VARCHAR2,V_MAIN IN VARCHAR2,V_UNIT IN VARCHAR2,V_SHG IN VARCHAR2,V_EMP_ID IN VARCHAR2,loan_rec_Tab out shg_qry.loan_dts_tab) AS
cursor c1 is select  A.COMP_CODE,A.MAIN_CODE,a.unit_code,a.loan_no,a.csa_code,b.client_name ,c.emp_id,b.regis_group,D.int_rate,D.INT_TYPE,
D.last_disbdate disbdt,D.total_disbamt disbamt,a.client_code,b.phone_nos
from bo119_prodsanction_mst a
,bo501_regis_hdr b
,cm010_emp_mst c
,BO301_LOAN_SUMM D where ..........

这是我的shg_qry.loan_dts_tab：

CREATE OR REPLACE PACKAGE shg_qry is

end shg_qry;
