SQL里有没有类似SPLIT的分割字符串函数

createfunctionf_split(@cvarchar(2000),@splitvarchar(2))

returns@ttable(colvarchar(20))

as

begin

while(charindex(@split,@c)<>0)

begin

insert@t(col)values(substring(@c,1,charindex(@split,@c)-1))

set@c=stuff(@c,1,charindex(@split,@c),'')

end

insert@t(col)values(@c)

return

end

go

select*fromdbo.f_split('dfkd,dfdkdf,dfdkf,dffjk',',')

dropfunctionf_split

col

--------------------

dfkd

dfdkdf

dfdkf

dffjk

扩展资料

巧用SQL内置函数分割字符串

createfunction[dbo].[fn_char_splitbystr](

@Stringnvarchar(4000),function

@Delimiternvarchar(100)

)

returns@ValueTabletable([FValue]nvarchar(4000),[FSerial]int)

as

begin

declare@valuenvarchar(4000),@valnvarchar(4000)

declare@NextStringnvarchar(4000),@Posint,@NextPosint,@CommaChecknvarchar(1),@idint

set@value=@String

set@id=1

set@NextString=''

set@CommaCheck=right(@value,1)

set@value=@value+@Delimiter+space(len(@Delimiter)-1)

set@Pos=charindex(@Delimiter,@value)

set@NextPos=1

while(@pos<>0)begin

set@NextString=substring(@value,1,@Pos-1)

set@val=@NextString

if@id>1set@val=substring(@val,len(@Delimiter),len(@val))

insertinto@ValueTable([FValue],[FSerial])VALUES(@val,@id)

set@value=substring(@value,@pos+1,LEN(@value))

set@NextPos=@Pos

set@pos=charindex(@Delimiter,@value)

set@id=@id+1

end

return

end

SQL里有没有类似SPLIT的分割字符串函数
CREATE OR REPLACE TYPE split_type IS TABLE OF VARCHAR2 (4000) /（2）定义split函数：
CREATE OR REPLACE FUNCTION split (p_str IN VARCHAR2, p_delimiter IN VARCHAR2) RETURN split_type IS j INT := 0; i INT := 1; len INT := 0; len1 INT := 0; str VARCHAR2 (4000); my_split split_type := split_type (); BEGIN len := LENGTH (p_str); len1 := LENGTH (p_delimiter); WHILE j < len LOOP j := INSTR (p_str, p_delimiter, i); IF j = 0 THEN j := len; str := SUBSTR (p_str, i); my_split.EXTEND; my_split (my_split.COUNT) := str; IF i >= len THEN EXIT; END IF; ELSE str := SUBSTR (p_str, i, j - i); i := j + len1; my_split.EXTEND; my_split (my_split.COUNT) := str; END IF; END LOOP; RETURN my_split; END split; /（3）存储过程中，使用类似
