Read string with comma and insert into sql table single row - sql

Question

Table
Column A Column B Column C
----------------------------------------------
I have an input string like (Apple,Banana,Orange). I need to insert these values to the above table.
Result should be like
ColumnA Column B Column C
-------------------------------------------
Apple Banana Orange
Is it possible using a procedure that takes the input parameter as a csv string?

Answer 1

Please use the below code to get the list of column name. You can pass the same to SP for inserting to your table.
BEGIN
DECLARE #str VARCHAR(2000)
DECLARE #input VARCHAR(4000)
DECLARE #ind Int
DECLARE #Count int
DECLARE #max int
SET #max =0
DECLARE #table TABLE(ColumnA varchar(10),ColumnB varchar(10),ColumnC varchar(10))
DECLARE #Result TABLE (ID int identity(1,1),value varchar(1000))
SET #input ='Apple,Banana,Orange'
IF(#input is not null)
BEGIN
SET #ind = CharIndex(',',#input)
WHILE #ind > 0
BEGIN
SET #str = SUBSTRING(#input,1,#ind-1)
SET #input = SUBSTRING(#input,#ind+1,LEN(#input)-#ind)
INSERT INTO #Result values (#str)
SET #ind = CharIndex(',',#input)
END
SET #str = #input
INSERT INTO #Result values (#str)
END
SET #Count = (SELECT Max(ID) from #Result)
WHILE #Count > #max
BEGIN
SET #max = #max +1
DECLARE #Value varchar(1000)
SET #Value = (SELECT value from #Result WHERE ID =#max)
SELECT #value
END
END

Please check following SQL script which splits input string parameter and inserts into a table
Please note that I use SQL split string function dbo.Split and you can find the source codes at referred SQL tutorial
You will need such a user defined split function unless you use SQL Server 2016
/*
create table TableT (
[Column A] varchar(100),
[Column B] varchar(100),
[Column C] varchar(100)
)
*/
declare #string varchar(max) = 'Apple,Banana,Orange'
select * from dbo.Split(#string, ',')
insert into TableT
select
MAX([Column A]) as [Column A],
MAX([Column B]) as [Column B],
MAX([Column C]) as [Column C]
from (
select
case when id = 1 then val end as [Column A],
case when id = 2 then val end as [Column B],
case when id = 3 then val end as [Column C]
from dbo.Split(#string, ',')
) s
select * from TableT

Please make use of the below query. Its working fine in SQL Server 2012.
BEGIN
DECLARE #input VARCHAR(4000)
DECLARE #str VARCHAR(4000)
DECLARE #Query NVARCHAR(max)
SET #input ='(Apple,Banana,Orange)'
IF(#input is not null)
BEGIN
SET #str = (SELECT REPLACE(#input,'(','('''))
SET #str = (SELECT REPLACE(#str,')',''')'))
SET #str = (SELECT REPLACE(#str,',',''','''))
SET #Query ='INSERT INTO MyTable (ColumnA,ColumnB,ColumnC)VALUES '+#str
Exec (#Query)
END
END
