第一次用存储过程，关于处理待办的，不知道怎么执行和传参数 给存储过程 ，其实就一句话很简单。
@call PRC_MISSIONLIST_QUERY('27020214', '27040000', '27040900'); 或者call PRC_MISSIONLIST_QUERY('27020214', '27040000', '27040900');
其中的三个参数其实就是存储过程中的in 参数。
存储过程很复杂慢慢看。
(IN | OUT | INOUT parameter-name data-type,...) ：传入参数
IN：输入参数
OUT：输出参数
INOUT：作为输入输出参数
parameter-name：参数名字，在此存储过程中唯一的标识符。
data-type:参数类型，可以接收SQL类型和创建的表。不支持LONG VARCHAR, LONG VARGRAPHIC, DATALINK, REFERENCE和用户自定义类型。
SPECIFIC specific-name：唯一的特定名称（别名），可以用存储过程名代替，这个特定名称用于dorp存储过程，或者给存储过程添加注视用，但不能调用存储过程。如果不指定，则数据库会自动生成一个yymmddhhmmsshhn时间戳的名字。推荐给出别名。
DYNAMIC RESULT SETS integer：指定存储过程返回结果的最大数量。存储过程中虽然没有return语句，但是却能返回结果集。
CONTAINS SQL, READS SQL DATA, MODIFIES SQL DATA： 指定存储过程中的SQL访问级别
CONTAINS SQL： 表示存储过程可以执行中，既不可读取 SQL 数据，也不可修改 SQL 数据。
READS SQL DATA： 表示存储过程可以执行中，可读取SQL，但不可修改 SQL 数据。
MODIFIES SQL DATA： 表示存储过程可以执行任何 SQL 语句。可以对数据库中的数据进行增加、删除和修改。
DETERMINISTIC or NOT DETERMINISTIC：表示存储过程是动态或者非动态的。动态的返回的值是不确定的。非动态的存储过程每次执行返回的值是相同的。
CALLED ON NULL INPUT：表示可以调用存储过程而不管任何的输入参数是否为NULL，并且，任何的OUT或者INOUT参数可以返回一个NULL或者非空值。检验参数是否为NULL是在过程中进行的。
INHERIT SPECIAL REGISTERS：表示继承专用寄存器。
OLD SAVEPOINT LEVEL or NEW SAVEPOINT LEVEL：建立存储点。OLD SAVEPOINT LEVEL是默认的存储点。
LANGUAGE SQL：指定程序的主体用的是SQL语言。
EXTERNAL ACTION or NO EXTERNAL ACTION：表示存储过程是否执行一些改变理数据库状态的活动，而不通过数据库管理器管。默认是 EXTERNAL ACTION。如果指定为NO EXTERNAL ACTION ,则数据库会确定最最佳优化方案。
PARAMETER CCSID：指定所有输出字符串数据的编码,默认为UNICODE编码数据库为PARAMETER CCSID UNICODE ，其他的数据库默认为PARAMETER CCSID 3 ASCII。
SQL-procedure-body：存储过程的主体
----------SQL-variable-declaration：变量声明
- SET variable-name = value
- SET variable-name = (SELECT statement)
常见的逻辑语句有：IF，CASE，FOR,WHILE,ITERATE,LEAVE,LOOP,REPEAT,GOTO语句
- >>--CLOSE--cursor-name-----------------------------------------><
>>--CLOSE--cursor-name-----------------------------------------><1.说明：关闭游标
- >>--CALL--procedure-name(parameter list)-----------------------><
- DROP SPECIFIC PROCEDURE specific-name
- DROP PROCEDURE procedure-name(parameter list)
DROP SPECIFIC PROCEDURE specific-name DROP PROCEDURE procedure-name(parameter list)example: DROP SPECIFIC PROCEDURE SUM_ab;(假设上面SUM存储过程的SPECIFIC为SUM_ab) DROP PROCEDURE SUM(INT,INT,INT)
