Inserting using CSV - sql-server

I have a table with two fields Name and ID.
Name comes from input parameter #Name and ID comes a CSV #CSVID.
I have a spilt function that return a temp table .
My stored proc is
INSERT INTO dbo.MyTable
(
Name,
ID
)
VALUES
(
(SELECT #Name, id FROM dbo.Split(#CSVID))
)
My split function
ALTER FUNCTION [dbo].[Split] (#InStr VARCHAR(MAX))
RETURNS #TempTab TABLE
(id int not null)
AS
BEGIN
;-- Ensure input ends with comma
SET #InStr = REPLACE(#InStr + ',', ',,', ',')
DECLARE #SP INT
DECLARE #VALUE VARCHAR(1000)
WHILE PATINDEX('%,%', #INSTR ) <> 0
BEGIN
SELECT #SP = PATINDEX('%,%',#INSTR)
SELECT #VALUE = LEFT(#INSTR , #SP - 1)
SELECT #INSTR = STUFF(#INSTR, 1, #SP, '')
INSERT INTO #TempTab(id) VALUES (#VALUE)
END
RETURN
END
So what I want is
say
#Name = 'John Doe'
#CSVID = '1,2'
Then I want the result of insert to be
Name ID
John 1
Jhon 2
I saw so many example but they were all so complicated. I just a simple explanation as to how insert works if the subquery
SELECT * FROM dbo.Split(#CSVID)
returns more than 1 value.
Thanks

INSERT INTO dbo.MyTable(Name, ID)
SELECT #Name,
id
FROM dbo.Split(#CSVID)

Add columns dynamically and Later Parse values in the respective columns

I have an SP which accepts the Inputtable as parameter, My Inputtable is as shown in the code
`create table inputTable ( id int,ItemQty varchar(100))
insert into inputTable(id, ItemQty) values(1,'a,b,c')
insert into inputTable(id, ItemQty) values(2,'x,y')
insert into inputTable(id, ItemQty) values(3,'l,m,n,o,p')
insert into inputTable(id, ItemQty) values(4,'a,b')
insert into inputTable(id, ItemQty) values(5,'m')`
and SP i have written is like below
`ALTER PROCEDURE [dbo].[Column_Dynamics] (#tablename varchar(50))
AS
BEGIN
-----
declare #maxcount as int
set #maxcount='select MAX(len(ITEMQTY) - len(replace(ITEMQTY, '','', '''')) +1) from '+#tablename
exec('select MAX(len(ITEMQTY) - len(replace(ITEMQTY, '','', '''')) +1) from '+#tablename)
print #maxcount
exec #maxcount
print #maxcount
declare #var varchar(100)
IF EXISTS(SELECT * FROM sys.columns WHERE object_id = Object_id(#tablename))
set #var='alter table '+ #tablename +' ADD column QTY1'
exec(#var)
select * from #tablename
select max(len(ItemQty))-max(len(replace(ItemQty, ',', ''))-1) from inputtable
END`
My table is :
step 1 ) I want to add the columns dynamically to inputtable like QTY1,QTY2,QTY3,QTY4,QTY5 because maximum count of ItemQty column is 5, by considering comma as delimiter as shown in figure1
**step 2) ** Parse values in the respective columns(by considering the delimiter comma (,).as shown in figure2
Later SP: I got till here, But Not getting the second step, that is update Parse values in the respective columns.
ALTER PROCEDURE dynamic_tbl (#tablename varchar(50))
AS
BEGIN
DECLARE #ColumnCount int
DECLARE #rowcount TABLE (Value int);
INSERT INTO #rowcount
EXEC('select MAX(len(ITEMQTY) - len(replace(ITEMQTY, '','', '''')) +1) from '+#tablename);
SELECT #ColumnCount = Value FROM #rowcount;
Declare #ColumnName nvarchar(10)='qty_'
Declare #count int =0
IF(#ColumnCount>0)
BEGIN
IF (EXISTS (SELECT * FROM INFORMATION_SCHEMA.TABLES WHERE TABLE_SCHEMA = 'dbo' AND TABLE_NAME = 'dyn_tbl'))
BEGIN
DROP TABLE dyn_tbl
END
select * into dyn_tbl from inputtable
SET #count=#count +1;
WHile(#ColumnCount>=#count)
BEGIN
SET #ColumnName='qty_'+CONVERT(varchar(2),#count)
EXEC ('ALTER TABLE dyn_tbl ADD ['+#ColumnName +'] varchar(20)')
declare #myvar as varchar(max)
set #myvar='update '+#tablename+' set '+#ColumnName +' =itemQty'
--exec dynamic_tbl 'dyn_tbl'

Procedure to alter given table dynamically based on column length as you have asked
Alter PROCEDURE [dbo].[Column_Dynamics] (#tablename varchar(50))
AS
BEGIN
drop table ##temp
declare #query1 varchar(max)
exec ( '
create table ##temp (id int identity,columnsl varchar(100))
declare #maxcount as int
set #maxcount = (select MAX(len(ITEMQTY) - len(replace(ITEMQTY, '','', '''')) +1) from '+#tablename+')
declare #count int = 1
while (#count <= #maxcount)
begin
declare #colvar nvarchar(100)= ''QTY''
set #colvar = concat(#colvar,#count)
set #count = #count + 1
insert into ##temp select #colvar
end
')
declare #tempstart int = 1
declare #templast int = (select count(*) from ##temp)
declare #updatecol varchar(100) = ''
while (#tempstart <= #templast)
Begin
set #updatecol = (select columnsl from ##temp where id = #tempstart)
exec ('alter table '+#tablename+' Add '+#updatecol+' varchar(100) ')
set #tempstart = #tempstart + 1
end
End
output for inputTable:
id ItemQty QTY1 QTY2 QTY3 QTY4 QTY5
1 a,b,c NULL NULL NULL NULL NULL
2 x,y NULL NULL NULL NULL NULL
3 l,m,n,o,p NULL NULL NULL NULL NULL
4 a,b NULL NULL NULL NULL NULL
5 m NULL NULL NULL NULL NULL
may not be the best way but works.
edit
Altered above procedure to perform both actions, Please use below procedure
Alter PROCEDURE [dbo].[Column_Dynamics] (#tablename varchar(50))
AS
BEGIN
-- declare #tablename varchar(100) = 'inputTable'
drop table #temp if object_id('temp..#temp') is not null drop table #temp

declare #count int = 1
while (#count <= #maxcount)
begin
declare #colvar nvarchar(100)= ''QTY''
set #colvar = concat(#colvar,#count)
set #count = #count + 1
insert into #temp
select #colvar
end
')
declare #tempstart int = 1
declare #templast int = (select count(*) from #temp)
declare #updatecol varchar(100) = ''
declare #itemqty varchar(100)
while (#tempstart <= #templast)
Begin
set #updatecol = (select columnsl from #temp where id = #tempstart)

declare #finvar table (id int identity,cols varchar(100))
insert into #finvar select cols from #sysvar where id not in (1,2)
declare #cat int = 1 declare #dog int = (select max(id) from inputTable)
while (#cat <= #dog)
begin
drop table #tab2
if object_id('temp..#tab2') is not null drop table #tab2
create table #tab2 (id int identity,fnvalues varchar(100))
set #itemqty = (select itemqty from inputTable where id = #cat)
insert into #tab2 select item from [dbo].[fnSplit](#itemQty,',')

set #cn = #cn + 1
end
set #cat = #cat + 1
End
End
output:
id ItemQty QTY1 QTY2 QTY3 QTY4 QTY5
1 a,b,c a b c NULL NULL
2 x,y x y NULL NULL NULL
3 l,m,n,o,p l m n o p
4 a,b a b NULL NULL NULL
5 m m NULL NULL NULL NULL
did not optimize the query but works fine.
However, if you have maximum Qty's are known which are in comma separated format then you could use xml node method to separate them into columns.QTY1...QTY5
SELECT DISTINCT ID, ITEMQTY,
a.value('/A[1]', 'VARCHAR(MAX)') as QTY1,
a.value('/A[2]', 'VARCHAR(MAX)') as QTY2,
a.value('/A[3]', 'VARCHAR(MAX)') as QTY3,
a.value('/A[4]', 'VARCHAR(MAX)') as QTY4,
a.value('/A[5]', 'VARCHAR(MAX)') as QTY5
FROM
(
SELECT ID, ITEMQTY,
CAST('<A>'+REPLACE(ITEMQTY, ',', '</A><A>')+'</A>' AS XML) AS ITEMQTY1
FROM inputTable
) A
CROSS APPLY ITEMQTY1.nodes('/A') AS split(a);
Result :
ID ITEMQTY QTY1 QTY2 QTY3 QTY4 QTY5
1 a,b,c a b c NULL NULL
2 x,y x y NULL NULL NULL
3 l,m,n,o,p l m n o p
4 a,b a b NULL NULL NULL
5 m m NULL NULL NULL NULL
Later, you could replace null by using coalesce() or isnull() function with ''
Use This
First Create a function
CREATE FUNCTION [dbo].[fn_split](
#str VARCHAR(MAX),
#delimiter CHAR(1)
)
RETURNS #returnTable TABLE (idx INT PRIMARY KEY IDENTITY, item VARCHAR(8000))
AS
BEGIN
DECLARE #pos INT
SELECT #str = #str + #delimiter
WHILE LEN(#str) > 0
BEGIN
SELECT #pos = CHARINDEX(#delimiter,#str)
IF #pos = 1
INSERT #returnTable (item)
VALUES (NULL)
ELSE
INSERT #returnTable (item)
VALUES (SUBSTRING(#str, 1, #pos-1))
SELECT #str = SUBSTRING(#str, #pos+1, LEN(#str)-#pos)
END
RETURN
END
GO
and use function like this
Declare #test TABLE (
ID VARCHAR(200),
Data VARCHAR(200)
)
insert into #test
(ID, Data)
Values
(1,'a,b,c')
insert into #test
(ID, Data )
values(2,'x,y')
insert into #test
(ID, Data )
values(3,'l,m,n,o,p')
insert into #test
(ID, Data )
values(4,'a,b')
insert into #test
(ID, Data )
values(5,'m')
select ID,data AS ItemQty,
ISNULL((select item from fn_split(Data,',') where idx in (1)),'') as QTY1 ,
ISNULL((select item from fn_split(Data,',') where idx in (2)),'') as QTY2,
ISNULL((select item from fn_split(Data,',') where idx in (3)),'') as QTY3,
ISNULL((select item from fn_split(Data,',') where idx in (4)),'') as QTY5 ,
ISNULL((select item from fn_split(Data,',') where idx in (5)),'') as QTY5
from #test
Output Same as your Image
instead of using
insert into #test
(ID, Data)
Values
(1,'a,b,c')
you can also assgin it like this
insert into #test
(ID, Data)
Values
(Select Column1, Column2 From YourTable)

How to resolve An INSERT EXEC statement cannot be nested in SQL server

I have a sp in which I am returning one single column result. I am trying to store the result into a table type, but I am getting this error:
An INSERT EXEC statement cannot be nested.
I have googled around but didn't find any acceptable solution.
The sp is as follows:-
ALTER PROCEDURE [dbo].[Sp_DemographicFilter_booster]
(
#FilterSelected FilterSelected READONLY,
#CountryCategoryId int=null
)
AS
BEGIN
SET NOCOUNT ON;
DECLARE #WhereCondition varchar(500) ;
DECLARE #QueryString Varchar(MAX) ;
DECLARE #QueryString_booster Varchar(MAX) ;
DECLARE #Filter table (FilterColumn Varchar(200),FilterValue Varchar(200))
DECLARE #Result table (SERIAL int)
DECLARE #Result_booster table (SERIAL int)
if( select top 1 FilterColumn FROM #FilterSelected where FilterColumn<>'HISPANIC') is NOT NULL
BEGIN
Insert into #Filter
Select * from #FilterSelected where FilterColumn<>'HISPANIC'

), 1, 1, ''), 'Not Assigned Yet')+')' AS SubjectList
FROM #Filter STD)A
print #WhereCondition
--INSERT INTO #DemoTbl
--select SUBSTRING(col1,1, CHARINDEX(':',col1,1)-1) MetricName,SUBSTRING(col1, CHARINDEX(':',col1,1)+1,LEN(Col1)) CatValue
--from dbo.UF_CSVDataToTable(#FilterSelectedSelected)
SET #QueryString='SELECT SERIAL FROM Logical.Demographic D
WHERE '+#WhereCondition+' and CountryCategoryId='+cast(#CountryCategoryId as varchar(10))
PRINT #QueryString
insert into #Result
EXEC(#QueryString)
--select * from #Result
END
IF(select top 1 FilterColumn FROM #FilterSelected where FilterColumn='HISPANIC') IS NOT NULL
BEGIN
Delete from #Filter;
DECLARE #Response varchar(20)=null;
Insert into #Filter
Select * from #FilterSelected where FilterColumn='HISPANIC'
select #Response=FilterValue from #Filter;
DECLARE #VariableID int=null;
select #VariableID=SurrogateKeyCounter from MetaData.Metadata_Screener where DBMetricName='HISPANIC';
SET #QueryString_booster='SELECT SERIAL FROM Logical.Response R

EXEC(#QueryString_booster)
END
DECLARE #Final_Result table (SERIAL int)
insert into #Final_Result
select * from #Result
UNION
select * From #Result_booster
select * from #Final_Result
END
I am calling this procedure like this:
declare #ds FilterSelected
insert into #ds values('Hispanic','yes')
#FilterSelected=#ds,#CountryCategoryId=100
DECLARE #DemoTbl TABLE (Serial INT)
Insert into #DemoTbl
EXEC Sp_DemographicFilter_booster #FilterSelected=#ds,
#CountryCategoryId=100
Call SP Sp_DemographicFilter_booster along with unique ID .
Inside Sp_DemographicFilter_booster SP create global table (##) stored result in global table with same unique ID AS ID field
Now when return to main SP access global table with where condition that unique ID

exec statement in sql for comma separated values

I have created a SP like below. where i will have to pass comma separated values to #ID parameter.I have given split function. It is working fine only if i give one value as ID. Kindly help how should i change the exec statement for the SP to give comma separated values like ('123',456) to SP
EXEC usp_2090_AppRej '54862','',''
ALTER PROCEDURE [dbo].[usp_2090_AppRej]

,#Comments VARCHAR(1000) = ''
,#ReturnMessage VARCHAR(500) OUTPUT
DECLARE #tblBPM TABLE (ids INT)
INSERT INTO #tblBPM
SELECT items
FROM dbo.Split(#ID, ',')
You are using SQL server try the following.
Create database function
ALTER FUNCTION [dbo].[fnSplit]
(
#sInputList VARCHAR(max) -- List of delimited items
,
#sDelimiter VARCHAR(max) = ',' -- delimiter that separates items
)
RETURNS #List TABLE ( item VARCHAR(max) )
BEGIN
DECLARE #sItem VARCHAR(max)
WHILE CHARINDEX(#sDelimiter, #sInputList, 0) <> 0
BEGIN
SELECT #sItem = RTRIM(LTRIM(SUBSTRING(#sInputList, 1,
CHARINDEX(#sDelimiter,
#sInputList, 0)
- 1))) ,
#sInputList = RTRIM(LTRIM(SUBSTRING(#sInputList,
CHARINDEX(#sDelimiter,
#sInputList, 0)
+ LEN(#sDelimiter),
LEN(#sInputList))))
IF LEN(#sItem) > 0
INSERT INTO #List
SELECT #sItem
END
IF LEN(#sInputList) > 0
INSERT INTO #List
SELECT #sInputList -- Put the last item in
RETURN
END
Create SP
CREATE PROCEDURE [dbo].[usp_2090_AppRej]

AS
BEGIN
DECLARE #tblBPM TABLE ( ids INT )

Getting values of comma separated fields in SQL Server

I have comma separated column which represents the ids of cities like:
ID | Name
1 | 1,2,3
2 | 2,3,4
I want to make query to get name of the this value field. There is City Table which has two columns: id and name of cities
EXPECTED OUTPUT
ID | VALUES
1 | mumbai,delhi,pune
2 | delhi,pune,chennai
I can make a query if there is only one id in a column like:
select data.id,city.name from data,city where data.values=city.cityid
but I am not getting how to retrieve the data if there are multiple comma-separated values in one field.
The easy way is to convert CSV values to rows for each Id, join that with CITY table and convert back to CSV values. I have written the logic inside the query.
;WITH CTE1 AS
(
-- Convert CSV to rows
SELECT Id,LTRIM(RTRIM(Split.a.value('.', 'VARCHAR(100)'))) 'NAME'
FROM
(
-- To change ',' to any other delimeter, just change ',' before '</M><M>' to your desired one
SELECT Id,CAST ('<M>' + REPLACE(Name, ',', '</M><M>') + '</M>' AS XML) AS Data
FROM #TEMP
) AS A
CROSS APPLY Data.nodes ('/M') AS Split(a)
)
,CTE2 AS
(
-- Now join the values in rows with Id in CITY table
SELECT T.ID,T.NAME,C.CITYNAME
FROM CTE1 T
JOIN #CITY C ON T.NAME=C.ID
)
-- Now convert back to CSV format
SELECT DISTINCT ID,
SUBSTRING(
(SELECT ', ' + CITYNAME
FROM CTE2 I
WHERE I.Id=O.Id
FOR XML PATH('')),2,200000) [VALUES]
FROM CTE2 O

SQL - Determine the most frequently occuring words within a column

Is there an easy way of determining the most frequently occuring word in a column/field using T-SQL or VBA?
I am working on a fuzzy matching system for two given recordsets and would like to produce a matching string where the most frequently occuring words are removed. As the data is from a customer relations management database terms like "limited", "ltd", "plc" and "CORPORATION" would be removed.
