I have a SQL Server columns with data like this:
formula amount ficheno
-----------------------------
100*444 100 6555
10*698 698 6555
I've already tried on SQL Server converted varchar to double getting error.
Need to get formula field to resulted field...
You can evaluate an expression using dynamic SQL:
declare #sql nvarchar(max) = (
select string_agg(cast(
'select ' + formula + ', ' + str(amount) + ', ' + str(ficheno)
as nvarchar(max)), ';')
from YourTable
);
declare #temp table (id int, amount int, ficheno int);
insert #temp exec(#sql);
select * from #temp;
-->
id amount ficheno
44400 100 6555
6980 698 6555
Working example at db<>fiddle.
Ive followed your query and succeed Thank you so much #Andomar. Reviewed code to work on sql server<2017 with stuff function. If anyone is looking for answer ;
declare #sql nvarchar(max) = (
SELECT STUFF( (SELECT ' select ' + str([LOGICALREF]) + ', ' + str([LOGICALREFI]) + ', ' + REPLACE( Formül,',','.') +';'
from BM_211_URETIM_PLANLANAN t
for xml path ('')
), 1, 1, '' )
)
declare #temp table ( [LOGICALREF] int, [LOGICALREFI] int, [Planlanan Miktar] FLOAT);
insert #temp exec(#sql);

I am developing a custom application using CodeIgniter and MSSQL Server. Here i am using stored procedures.
Now i am wondering to implement codeigniter query type functionality where i can create a universal stored procedure in SQL Server and at the time of using i can pass tablename, array of fields and values.
It can work for both insert and update.
Something like we do in CodeIgniter to execute the query,
$data = array('fieldname1' => 'value1',
'fieldname2' => 'value2');
$this->db->insert($tablename,$data);
Just like this if we can pass the table name and array of the data to stored procedure and stored procedure automatically execute it.
If this can be done, it can save lots n lots of man hours. If anyone have already done i will be very much happy to see the solution.
You need to make string very specific in this case.
Figure out your table name, Column name, Column values for insert. For update 2 more parameters are required Id column name and its value.
GO
---- exec InsertUpdate 'tablename', 'col1, col2, col3', 'val1, val2, val3', 'idcol', 'idval'
GO
Create proc InsertUpdate
( #TableName nvarchar(500),
#ColName nvarchar(max),
#ColValues nvarchar(max),
#IDColName nvarchar(100) = '', --- for update only otherwise null
#IdColValue nvarchar(Max) = '' --- for update only otherwise null
)
As
Begin
declare #Query nvarchar(max)
if (#IdColValue = '')
Begin
set #Query = ' Insert into ' + #TableName + ' (' + #ColName + ') values (' + #ColValues + ')'
End
Else
Begin
;with CtColumn as (
select ROW_NUMBER() over (order by (select 1000)) as Slno, * from Split(#ColName,',') )
, CtValue as (
select ROW_NUMBER() over (order by (select 1000)) as Slno, * from Split(#ColValues, ','))
, CTFinal as (
select CCOl.Slno, CCOl.Items as ColName, CVal.Items as ColValue from CtColumn as CCOl inner join CtValue as CVal on CCOl.Slno=CVal.Slno )
select #Query = 'update ' + #TableName + ' set ' +
stuff ( (select ',' + ColName + '=' + ColValue from CTFinal for xml path ('')) ,1,1,'') +
' where ' + #IDColName + '=' + #IdColValue
End
exec sp_executesql #Query
End
Go
I have a table with around 10 rows. I want to pivot on all values in one column to a one-row multi column result. It looks as though there is no way to get around the "For ContactTypeID in ([1],[2])" syntax.
ContactTypeID int
ContactType varchar(20)
Sample data:
1 Customer
2 Vendor
...
5 BillTo
I want to return a single row with
Customer Vendor BillTo, etc
1 2 5
But like I said, I don't want to have to specify each ContactTypeID by number. Is there way to specify "for all"?
Thank you.
You need a dynamic pivot.
Here's the code, for your reference. Hope it helps.
CREATE TABLE tablename (ContactTypeID int, ContactType varchar(20));
INSERT INTO tablename VALUES (1, 'Customer'), (2, 'Vendor'), (5, 'BillTo');
DECLARE #cols NVARCHAR (MAX);
SELECT #cols = COALESCE (#cols + ',[' + ContactType + ']',
'[' + ContactType + ']')
FROM (SELECT DISTINCT [ContactType] FROM tablename) PV
ORDER BY [ContactType]
DECLARE #query NVARCHAR(MAX)
SET #query = '
SELECT * FROM
(
SELECT * FROM tablename
) x
PIVOT
(
MIN(ContactTypeID)
FOR [ContactType] IN (' + #cols + ')
) p
'
EXEC SP_EXECUTESQL #query;
I need to generate a dynamic sql in below specified format where my table is a parameter i.e, Number of columns is not static
For example, below may be the table schema
ID Name
1 asd
2 xyz
I need a query which generates the select statement as below
select 'ID :' + ID + ',Name :'+Name from table
The output from generated above sql will be like this
ID : 1, Name:asd
ID : 2, Name:xyz
If the table has more number of columns, select statement that needs to be changes varies as below
select 'ID :' + ID + ',Name :'+Name + ',Col3 :' + Col3 ...from table
Could someone help me regarding this
Thanks,
Sree
Here is one option which uses a little XML and string manipulation
I should add, NULL values will be excluded.
Example
Declare #YourTable Table ([ID] varchar(50),[Name] varchar(50))
Insert Into #YourTable Values
(1,'asd')
,(2,'xyz')
Select stuff(
replace(
replace(
replace(
replace(
(Select * from #YourTable for XML RAW)
,'<row ',',')
,'="',':')
,'" ',',')
,'"/>','')
,1,1,'')
Returns
(No column name)
ID:1,Name:asd,ID:2,Name:xyz
Use the information schema views. They contain all the information you need to generate your dynamic sql. The rest is just simple SQL and patience.
I am able to achieve this using below sql
DECLARE #TableName VARCHAR(MAX) = 'tableName'
DECLARE #SQL VARCHAR(MAX) = 'SELECT ''{''+'''
SELECT #SQL = #SQL + '
"'+COLUMN_NAME+'":"''' + '+coalesce(CAST('+COLUMN_NAME+' AS VARCHAR(MAX)),'''')+''",' FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME = #TableName
SET #SQL = LEFT(#SQL,LEN(#SQL)-1) + '
}'' FROM ' + #TableName
PRINT #SQL

I have two tables. I write a query. Date is dynamic. I can select any date. `
select a.MP,a.CP,a.Frequency,a.Time,CONVERT(varchar(12),b.date,101) as
EntryDate,b.actualtime from mpcp a, DailyData b
where a.UserID=1 and a.MpCpId=b.MpCpId and
CONVERT(varchar(12),b.EntryDate,101) between
CONVERT(varchar(12),GETDATE()-5,101) and
CONVERT(varchar(12),GETDATE()+25,101)`
Output
But i want output like
Assuming that i am storing your result in one temp table and imaging data i created one data for your requirement
try this one whether it is useful or not
create table #piv
(
mp varchar(10),
cp varchar(10),
freq varchar(10),
time int,
entryd date,
acuralize int
)
insert into #piv values
('don','asper','da',30,getdate(),0),
('dwm','donl','da',10,getdate(),3),
('qar','qpr','da',15,getdate(),5),
('qar','qpr','da',15,'01-16-17',5),
('qar','qpr','da',15,'01-15-17',5),
('qar','qpr','da',15,'01-16-17',5)
SELECT * FROM #piv
Declare #SQL varchar(max) = Stuff((Select Distinct ',' + QuoteName(entryd) From #piv Order by 1 For XML Path('')),1,1,'')
Select #SQL = '
Select *,' + #SQL + '
From #piv
Pivot (max(time) For [entryd] in (' + #SQL + ') ) p'
Exec(#SQL);
You can create a dynamic pivot. A good example is available on this link.
Good Luck !
DECLARE #cols VARCHAR(max),#sql VARCHAR(max)
SELECT #cols=ISNULL(#cols+',[','[')+ CONVERT(VARCHAR,a.EntryDate,101)+']'
FROM mpcp a, DailyData b
where a.UserID=1 and a.MpCpId=b.MpCpId and DATEDIFF(d,GETDATE(),b.EntryDate) BETWEEN -5 AND 25
GROUP BY a.time
SET #sql='
SELECT * FROM (
SELECT a.MP,a.CP,a.Frequency,a.Time,CONVERT(varchar(12),b.date,101) AS EntryDate,b.actualtime
FROM mpcp a, DailyData b
WHERE a.UserID=1 and a.MpCpId=b.MpCpId and where a.UserID=1 and a.MpCpId=b.MpCpId and DATEDIFF(d,GETDATE(),b.EntryDate) BETWEEN -5 AND 25
) AS t
PIVOT (MAX(actualtime) FOR EntryDate IN ('+#cols+') )'

This solution is for an unbounded Gridview paging and having problem with the syntax of this query:
> #currTable varchar(20),
#startRowIndex int,
#maximumRows int,
#totalRows int OUTPUT
AS
DECLARE #first_id int, #startRow int
IF #startRowIndex = 1
SET #startRowIndex = 1
ELSE
SET #startRowIndex = ((#startRowIndex - 1) * #maximumRows)+1
SET ROWCOUNT #startRowIndex
DECLARE #sql varchar(250);
SET #sql = 'SELECT ID, StringID_from_Master, GUID, short_Text, lang_String, date_Changed, prev_LangString, needsTranslation, displayRecord, brief_Descrip FROM ' + #currTable + ' ';
EXECUTE(#sql);
PRINT #first_id
SET ROWCOUNT #maximumRows
SELECT #sql = 'SELECT ' + CAST(#first_id as varchar(20)) + ' = ID FROM ' + QUOTENAME(#currTable) + ' ORDER BY ID ' ;
EXEC (#sql);
SET ROWCOUNT 0
-- Get the total rows
SET #sql = 'SELECT ' + + CAST(#totalRowsas varchar(20)) + ' = COUNT(ID) FROM ' + #currTable + ' ';
EXECUTE(#sql);
RETURN
<
The errors is:
Conversion failed when converting the varchar value ''SELECT ' to data type int.
Tried also
nvarchar and varchar. = + CAST(#first_id as varchar(10)) +
If you're trying to implement paging, this is wrong in so many ways. First, you're using SET ROWCOUNT to limit to #startRowIndex, but then you're selecting ALL n rows (with no ORDER BY), then getting the first ID, then counting the total rows by selecting from the table? Might I suggest a better approach?
CREATE PROCEDURE dbo.PageSmarter
#Table NVARCHAR(128), -- table names should not be varchar(20)
#FirstRow INT,
#PageSize INT,
#TotalRows INT OUTPUT
AS
BEGIN
SET NOCOUNT ON; -- always, in every stored procedure
DECLARE
#first_id INT,
#startRow INT,
#sql NVARCHAR(MAX);
SET #sql = N'WITH x AS
(
SELECT
ID,
rn = ROW_NUMBER() OVER (ORDER BY ID)
FROM
' + #Table + '
)
SELECT rn, ID
INTO #x FROM x
WHERE rn BETWEEN ' + CONVERT(VARCHAR(12), #FirstRow)
+ 'AND (' + CONVERT(VARCHAR(12), #FirstRow)
+ ' + ' + CONVERT(VARCHAR(12), #PageSize) + ' - 1);
SELECT first_id = MIN(ID) FROM #x;
SELECT
ID, StringID_from_Master, GUID, short_Text, lang_String, date_Changed,
prev_LangString, needsTranslation, displayRecord, brief_Descrip
FROM ' + #Table + ' AS src
WHERE EXISTS
(
SELECT 1 FROM #x
WHERE ID = src.ID
);';
EXEC sp_executeSQL #sql;
SELECT #totalRows = SUM(row_count)
FROM sys.dm_db_partition_stats
WHERE [object_id] = OBJECT_ID(#Table);
END
GO
DECLARE #tr INT;
EXEC dbo.PageSmarter 'dbo.tablename', 10, 2, #tr OUTPUT;
SELECT #tr;
I haven't tested all edge cases with this specific implementation. I will confess, there are much better ways to do this, but they usually aren't complicated with the additional requirement of dynamic table names. This suggests that there is something inherently wrong with your design if you can run the exact same queries against any number of tables and get similar results.
In any case, you can review some of the (quite lengthy) discussion about various approaches to paging over at SQL Server Central:
http://www.sqlservercentral.com/articles/T-SQL/66030/
There are 62 comments following up on the article:

I am guessing your #first_id field is an int. If so, then you need to CAST/Convert your #first_id value to a string/varchar.
CAST(#first_id as varchar(10))
or
Convert(varchar(10), #first_id)
MSDN documentation on CAST/Convert for SQL server
EDIT: After looking at your query again, I notice that you are setting your #first_id = ID, This is incorrect syntax, the correct syntax would be below.
SELECT #sql = 'SELECT ID AS ' + CAST(#first_id as varchar(10)) + ' FROM ' +
QUOTENAME(#currTable) + ' ORDER BY ID ' ;
EXEC (#sql);
It appears you're trying to create an alias for your column ID. The string you're building won't result in a valid SQL statement if it contains a number. It would come out to something like this:
SELECT 123 = ID FROM dbo.MyTable ORDER BY ID
Try this:
SELECT ID AS '123' FROM dbo.MyTable ORDER BY ID
To achieve that:
SELECT #sql = 'SELECT ID AS ''' + CAST(#first_id as varchar(10)) +
''' FROM ' + QUOTENAME(#currTable) +
' ORDER BY ID ' ;
I would do it this way
create table #e (a int)
SET #sql = 'insert #e SELECT COUNT(ID) FROM ' + #currTable + ' ';
exec(#sql)
select #totalRows = a from #e
drop table #e
