MySQL结果由存储过程-Insert Statement上的多行组成

Question

这是我的存储过程，我遇到了麻烦......我正在

insert into PK_SAMPLES(U_KEY) select cf_extEmployeeId from salesreps;
set v_queryid = v_queryid + 1;
select RULEID INTO v_RuleId from TAB_RULE_LIST WHERE RULEID=3;
select DISTINCT T_TABLENAME INTO v_T_TABLENAME from TAB_RULE_LIST WHERE RULEID=3 and T_TABLENAME is not null;

select T_COLUMNNAME INTO v_t_columnname FROM mapping_table where constraint_type='PK';

IF (v_RuleId = 3) THEN

        SET V_JOIN_QUERY = ''; 
        SET source_columns = '';
        SET target_columns = '';

        CREATE TEMPORARY TABLE IF NOT EXISTS source_target_column_list

  select count(0) INTO V_MODIFIED_DATE_COUNT FROM mapping_table WHERE T_TABLENAME=v_T_TABLENAME AND TRANSFORMATION_TYPE='MODIFIED_DATE';

        SELECT COUNT(*) FROM PK_SAMPLES INTO n_pk_sample;
        SET i_pk_sample = 0;
        WHILE i_pk_sample < n_pk_sample DO 
            select U_KEY into v_value from PK_SAMPLES;
            SET v_source_query_1 = CONCAT(v_source_query, ' where ', v_s_columnname, ' = ''', v_value, '''');
            SET V_TARGET_QUERY_1 = CONCAT(V_TARGET_QUERY, ' where ', v_t_columnname, ' = ''', v_value, '''');
            CALL QUERY_INSERT_PROC(v_queryid, v_RULEID,v_T_TABLENAME,V_SOURCE_QUERY_1,V_TARGET_QUERY_1,v_version_number,v_RMID,v_MODULE_NAME);                              
            SET i_pk_sample = i_pk_sample + 1;
        END WHILE;
END IF;

END//
DELIMITER ;

由于insert语句，结果由多行组成。

如果有人能帮助我找到解决方案，我将不胜感激。

感谢。
