第一次用存儲過程,關於處理待辦的,不知道怎麼執行和傳參數 給存儲過程 ,其實就一句話很簡單。數據庫
@call PRC_MISSIONLIST_QUERY('27020214', '27040000', '27040900'); 或者call PRC_MISSIONLIST_QUERY('27020214', '27040000', '27040900');ssh
其中的三個參數其實就是存儲過程當中的in 參數。fetch
存儲過程很複雜慢慢看。優化
(IN | OUT | INOUT parameter-name data-type,...) :傳入參數
IN:輸入參數
OUT:輸出參數
INOUT:做爲輸入輸出參數
parameter-name:參數名字,在此存儲過程當中惟一的標識符。
data-type:參數類型,能夠接收SQL類型和建立的表。不支持LONG VARCHAR, LONG VARGRAPHIC, DATALINK, REFERENCE和用戶自定義類型。 編碼
SPECIFIC specific-name:惟一的特定名稱(別名),能夠用存儲過程名代替,這個特定名稱用於dorp存儲過程,或者給存儲過程添加註視用,但不能調用存儲過程。若是不指定,則數據庫會自動生成一個yymmddhhmmsshhn時間戳的名字。推薦給出別名。 url
DYNAMIC RESULT SETS integer:指定存儲過程返回結果的最大數量。存儲過程當中雖然沒有return語句,可是卻能返回結果集。spa
CONTAINS SQL, READS SQL DATA, MODIFIES SQL DATA: 指定存儲過程當中的SQL訪問級別
CONTAINS SQL: 表示存儲過程能夠執行中,既不可讀取 SQL 數據,也不可修改 SQL 數據。
READS SQL DATA: 表示存儲過程能夠執行中,可讀取SQL,但不可修改 SQL 數據。
MODIFIES SQL DATA: 表示存儲過程能夠執行任何 SQL 語句。能夠對數據庫中的數據進行增長、刪除和修改。 code
DETERMINISTIC or NOT DETERMINISTIC:表示存儲過程是動態或者非動態的。動態的返回的值是不肯定的。非動態的存儲過程每次執行返回的值是相同的。 blog
CALLED ON NULL INPUT:表示能夠調用存儲過程而無論任何的輸入參數是否爲NULL,而且,任何的OUT或者INOUT參數能夠返回一個NULL或者非空值。檢驗參數是否爲NULL是在過程當中進行的。
INHERIT SPECIAL REGISTERS:表示繼承專用寄存器。
OLD SAVEPOINT LEVEL or NEW SAVEPOINT LEVEL:創建存儲點。OLD SAVEPOINT LEVEL是默認的存儲點。
LANGUAGE SQL:指定程序的主體用的是SQL語言。
EXTERNAL ACTION or NO EXTERNAL ACTION:表示存儲過程是否執行一些改變理數據庫狀態的活動,而不經過數據庫管理器管。默認是 EXTERNAL ACTION。若是指定爲NO EXTERNAL ACTION ,則數據庫會肯定最最佳優化方案。
PARAMETER CCSID:指定全部輸出字符串數據的編碼,默認爲UNICODE編碼數據庫爲PARAMETER CCSID UNICODE ,其餘的數據庫默認爲PARAMETER CCSID 3 ASCII。
SQL-procedure-body:存儲過程的主體 繼承
----------SQL-variable-declaration:變量聲明
