存儲過程拆分字元串

A. 如何在存儲過程中分割逗號分隔的字元串

create function f_split(@Sourcesql varchar(8000)) returns @temp table(a varchar(100)) as begin declare @i int set @SourceSql=rtrim(ltrim(@SourceSql)) set @i=charindex(',',@SourceSql) while @i>=1 begin insert @temp values(left(@SourceSql,@i-1)) set @SourceSql=substring(@SourceSql,@i+1,len(@SourceSql)-@i) set @i=charindex(',',@SourceSql) end if @SourceSql<>',' insert @temp values(@SourceSql) return end 用法 select * from dbo.f_split('abcd,efg,mm')

B. 求助：如何在存儲過程中拆分字元串

C. 關於oracle 存儲過程 如何切割一個字元串 轉化為字元數組，然後遍歷該數組： 類似ab，12；cd，55；k，7

給你寫了個包，包體代碼如下：
CREATE OR REPLACE PACKAGE BODY Pkg_Bai IS
-- 自定義個數組類型
TYPE Typ_Str_Array IS TABLE OF VARCHAR2(200) INDEX BY BINARY_INTEGER;
PROCEDURE Prc_String_To_Array(Pv_i_String IN VARCHAR2,
Pv_i_Identifier IN VARCHAR2,
Pt_o_Array OUT Typ_Str_Array) IS

Lv_Tmpstr VARCHAR2(200);
Lv_Changed_String VARCHAR2(4000);

BEGIN

-- 初始化
Lv_Changed_String := Pv_i_String;

-- 拆分邏輯
-- 1.字元串中沒有標識符
IF Instr(Pv_i_String, Pv_i_Identifier, 1, 1) = 0 THEN
Pt_o_Array(Pt_o_Array.Count + 1) := Pv_i_String;
ELSE

-- 2.字元串中有標識符
WHILE Instr(Lv_Changed_String, Pv_i_Identifier, 1, 1) > 0 LOOP
Lv_Tmpstr := Substr(Lv_Changed_String,
1,
Instr(Lv_Changed_String, Pv_i_Identifier, 1, 1) - 1);

Pt_o_Array(Pt_o_Array.Count + 1) := Lv_Tmpstr;
Lv_Changed_String := Substr(Lv_Changed_String,
Instr(Lv_Changed_String, Pv_i_Identifier, 1, 1) + 1,
Length(Lv_Changed_String));
END LOOP;

-- 3.最有一個被拆分出來的字元串中不含標識符
IF NOT Lv_Changed_String IS NULL THEN
-- 將最後一個保存
Pt_o_Array(Pt_o_Array.Count + 1) := Lv_Changed_String;
END IF;

END IF;

EXCEPTION
WHEN OTHERS THEN
NULL;
END;

PROCEDURE Prc_Test(Pv_i_Str IN VARCHAR2) IS
--定義數組
Lt_Array Typ_Str_Array;
Ln_Count NUMBER; -- 數組元素個數
Ln_Num NUMBER;
Lv_Value VARCHAR2(30);
BEGIN

Prc_String_To_Array(Pv_i_Str, ';', Lt_Array);
-- 循環數組
FOR i IN 1 .. Lt_Array.Count LOOP
-- 獲取每個元素中數值
Ln_Num := To_Number(TRIM(Substr(Lt_Array(i), Instr(Lt_Array(i), ',', -1) + 1)));
IF Ln_Num > 20 THEN
Lv_Value := TRIM(Substr(Lt_Array(i), 1, Instr(Lt_Array(i), ',', -1) - 1));
INSERT INTO a (col_a) VALUES (lv_value);
END IF;
END LOOP;
END;

END Pkg_Bai;

調用Prc_Test來分隔字元串並按要求比較後插入a表。我測試過，沒有問題。
需要注意的是，數據的要求：字元串中每組數據間使用英文小寫分號分隔，同一組數據字母在前，數字在後，以英文小寫逗號分隔。測試一下吧。
歡迎採納，不採納你都對不起我這20分鍾。呵呵......

E. 如何拆分調用SQL存儲過程後返回的字元串

string ID = Table[0].Rows[0][0].ToString();

sting[] arrID=ID.split(',');

把對象轉換成字元串不就可以了嗎？呵呵
希望對你有幫助

F. 我就是想在存儲過程當中，傳入一個字元串（不知道長度的）。然後把這個字元傳裡面的字元全部拆分開來。

給你個存儲過程

CREATE PROCEDURE p_split
@c varchar(8000),
@split varchar(5)

as
declare @t table( word varchar(20) )

begin

while(charindex(@split,@c)<>0)
begin
insert @t( word) values (substring(@c,1,charindex(@split,@c)-1))
set @c = stuff(@c,1,charindex(@split,@c),'') -- 刪除指定長度的字元並在指定的起始點插入另一組字元
end
insert @t(word) values (@c) ---最後一個不含分隔的加進來
select distinct * from @t
end
GO

還是用表變數

I. mysql存儲過程中 如何拆分字元串

MySQL分割字元串應該如何實現呢？下面就為您介紹MySQL分割字元串的實現方法步驟，希望可以讓您對MySQL分割字元串有更多的了解。

例如：update `edw_video` set company = substring(keyword,1,length(SUBSTRING_INDEX(keyword,",",1)))

名稱：SPLIT_SUB_STR1（取得split字元串的第一段）
參數：str 要split的目標字元串 （輸入格式為『11，2，3，4，5，6』； 輸出為『2，3，4，5，6』）
delimiter 分隔符 （『，』）
split1 輸出第一項（『11』）
存儲過程
CREATE DEFINER=`root`@`%` PROCEDURE `SPLIT_SUB_STR0`(inout str VARCHAR(1000) ,delimiter VARCHAR(1), out split1 VARCHAR(20))

BEGIN
# 名稱 SPLIT_SUB_STR1 取得分割字元串的第一段字元
# 參數inout str VARCHAR(1000) ,delimiter VARCHAR(1), out split0 VARCHAR(20)
# 輸入完整字元串，輸出去掉取得第一項後的字元串； 分隔符； 輸出split的第一個項目

#分割出第一段字元串不包括分隔符的長度
DECLARE SUB_STR_LENGTH INT;

# SUBSTRING_INDEX函數取得目標字元串左側第n個分割符左側的部分，n為負時返回右側第n個的右部分
SET SUB_STR_LENGTH = length(SUBSTRING_INDEX(str,delimiter,1));

#截取第一段字元串，不包括分隔符，放入輸出參數里
SET split0 = substring(str, 1, SUB_STR_LENGTH);

# 取得去掉第一個字元串和分隔符的字元串，進行下次循環取得下個字元串
SET str = substring(str, SUB_STR_LENGTH + 2 );
#測試一下輸出是否正確
#SELECT SUB_STR_LENGTH, SUB_STR_SPLIT0, STR;
END

調用實例

CREATE DEFINER=`root`@`%` PROCEDURE `test`()
BEGIN
#目標字元串
set @a = 』1,2,3,4,5,6,12『;
# 分隔符
set @c = ',';
# 存儲風格後的字元串
set @b = '';

REPEAT
# 調用上面的存儲過程
CALL SPLIT_SUB_STR0(@a, ',', @c);
#將取得的字元串拼接，測試用
set @b = concat(@b, @c);
#當目標字元串為空時，停止循環
UNTIL @a = ''
END REPEAT;
# 查看結果
select @a, @c, @b;

END;

J. Oracle中怎麼實現類似數組的功能，比如存儲過程我傳入一個長字元串，按照固定格式拆分成多個

給你個存儲過程

CREATE PROCEDURE p_split
@c varchar(8000),
@split varchar(5)

as
declare @t table( word varchar(20) )

begin

while(charindex(@split,@c)<>0)
begin
insert @t( word) values (substring(@c,1,charindex(@split,@c)-1))
set @c = stuff(@c,1,charindex(@split,@c),'') -- 刪除指定長度的字元並在指定的起始點插入另一組字元
end
insert @t(word) values (@c) ---最後一個不含分隔的加進來
select distinct * from @t
end
GO

還是用表變數
