用Fetch into a cursor%TYPE把要处理的数据放到记录集里。当一条数据不符条件时，用标签<
>和GOTO NEXT_RECORD
-- Function Name : CalculateImportCharge
-- Function Desc : Calculate Import Charge
-- Created by : Author
-- Created Date : 2003-05-16
FUNCTION CalculateImportCharge (
p_i_job_id IN VARCHAR2,
p_i_as_of_date_id IN VARCHAR2) RETURN NUMBER
AS
CURSOR cur_ShipBlHeader IS
SELECT import_folder_no
FROM GMY_SHIP_BL_HEADER
WHERE CANCEL_FLG = GMY_GA000_PKG.BL_CANCEL_FLG_OFF;
rec_ShipBlHeader cur_ShipBlHeader%ROWTYPE;
BEGIN
OPEN cur_ShipBlHeader;
FETCH cur_ShipBlHeader INTO rec_ShipBlHeader;
WHILE cur_ShipBlHeader%FOUND LOOP
x_num_error_code := GMY_GA000_PKG.CheckValidMasterBlNo (
p_i_job_id,
p_i_as_of_date_id,
rec_ShipBlHeader.import_folder_no,
x_vch_message);
IF x_num_error_code

COM_LOG.PUTLINE (p_i_job_id, x_vch_message);

COMMIT;

CLOSE cur_ShipBlHeader;
RETURN GMY_GA000_PKG.gn#OK;
EXCEPTION
WHEN OTHERS THEN
x_vch_message :=
p_i_job_id

|| SUBSTR (SQLERRM (SQLCODE), 1, 100);
COM_LOG.PUTLINE (p_i_job_id, x_vch_message);

2、当使用the Cursor FOR Loop循环时，在Loop循环里，把会出问题的情况写进一个独立的block块中，这个块包括完整的begin、end部分及exception异常处理部分。这样即使一条数据出现异常，也会继续执行下一条。
-- Function Name : GenerateInsCostInfRec
-- Function Desc : Generate records to transmit in INF table
-- Created by : SISS(AP)
-- Created Date : 2003-03-26
FUNCTION GenerateInsCostInfRec (
p_i_job_id IN VARCHAR2,
p_i_as_of_date_id IN VARCHAR2) RETURN NUMBER
AS
CURSOR cur_cost IS
SELECT cost.ROWID costRowId,
cost.import_folder_no,,
cost.insur_trans_id
FROM GMY_COST_BL cost,
GMY_COMMON_MST mst
WHERE cost.import_folder_no=invheader.import_folder_no
AND cost.billing_amt_num IS NOT NULL
AND cost.billing_amt_num!=0
AND cost.insur_db_cr!=0;
BEGIN
FOR rec_cost IN cur_cost LOOP
BEGIN
x_num_ret_value := GMY_GA000_PKG.CheckValidMasterBlNo(
p_i_job_id,
p_i_as_of_date_id,
rec_cost.import_folder_no,
x_vch_error_msg);
IF x_num_ret_value = GMY_GA000_PKG.VALID_BL_NO THEN
INSERT INTO GMY_COST_INS_INF(
cost_trx_id,,
created_by,
program_name)
VALUES(
GMY_COST_INS_INF_S.NEXTVAL,
PRG_NAME,

ELSIF x_num_ret_value = GMY_GA000_PKG.INVALID_BL_NO THEN
x_vch_error_msg := p_i_job_id

|| rec_cost.import_folder_no

COM_LOG.PUTLINE(p_i_job_id, x_vch_error_msg);
END IF;
EXCEPTION
WHEN OTHERS THEN
IF SQL%ROWCOUNT > 0 THEN -- check for 'too many rows'
x_vch_error_msg := p_i_job_id||' '||
SUBSTR(SQLERRM(SQLCODE),1,100);
COM_LOG.PUTLINE(p_i_job_id, x_vch_error_msg);
ELSE
x_vch_error_msg := p_i_job_id||' '||

COM_LOG.PUTLINE(p_i_job_id, x_vch_error_msg);
END IF;
END;
END LOOP;
COMMIT;
RETURN GMY_GA000_PKG.gn#OK;

x_vch_error_msg := p_i_job_id||' '||SUBSTR(SQLERRM(SQLCODE),1,100);
COM_LOG.PUTLINE(p_i_job_id, x_vch_error_msg);
ROLLBACK;
RETURN GMY_GA000_PKG.gn#NG;
END GenerateInsCostInfRec;
3、当使用the Cursor FOR Loop循环时，在Loop循环里，把会出问题的情况拆分成子函数，分别处理。
-- Function Name : CopyDsToActualDs
-- Function Desc : Copy the records from DS DB to Actual DS DB.
-- Created by : Author
-- Created Date : 2003-02-20
FUNCTION CopyDsToActualDs (
p_i_job_id IN VARCHAR2,
p_i_as_of_date_id IN VARCHAR2) RETURN NUMBER
IS
CURSOR cur_DsScc IS
SELECT *
FROM GMY_DS_SCC;
BEGIN
FOR rec_DsHead IN cur_DsScc LOOP
x_num_error_code := InsToActualScc(
