Issue:Unclosed quotation mark after the character string ''.

Unclosed quotation mark after the character string in SQL


Issue:Msg 105, Level 15, State 1, Line 1
Unclosed quotation mark after the character string ''.


Issue Reason: Apostrophe (')  is used in sql to start and end the string.So including  Apostrophe (')  in any string or varchar values will throw the above error.
for eg: if you run below query it will thrown the above error
Select 'Indian's'

Msg 105, Level 15, State 1, Line 1
Unclosed quotation mark after the character string ''.


Solution:To fix this issue you need to add one more Apostrophe (')
Select 'Indian''s'

Output:Indian's

Note :when Inserting the values containing   Apostrophe (') from your web application or system applications into SQL you can replace the Apostrophe (') with double Apostrophe ('') by using Replace Function.

Script -Deleting data of all tables of a Database in SQL

Script -Deleting data of all tables of a Database in SQL

The below Script will delete data from all tables of a Database.

Don't test the script in your Primary Database  although for data safety i have the script inside transaction block  and it will rollback all changes.
For tables having Referential Integrity truncate command will not work.So for that we are we are using Delete command.

--Tested and verified in SQL 2008 R2 and SQL2012

Begin tran

-- disable all referential integrity
EXEC sp_MSForEachTable 'ALTER TABLE ? NOCHECK CONSTRAINT ALL'
GO

EXEC sp_MSForEachTable '
 IF OBJECTPROPERTY(object_id(''?''), ''TableHasForeignRef'') = 1
  DELETE FROM ?
 else
  TRUNCATE TABLE ?
'
GO
-- enable all  referential integrity again
EXEC sp_MSForEachTable 'ALTER TABLE ? CHECK CONSTRAINT ALL'
GO
Rollback

Truncate will not Delete the Data if the table have referential Integrity(Foreign key) 
So for table having referential Integrity or foreign key Relation we are using Delete .
Test it by Removing the If condition that is deleting Data of all tables.

Begin tran

-- disable all referential integrity
EXEC sp_MSForEachTable 'ALTER TABLE ? NOCHECK CONSTRAINT ALL'
GO

EXEC sp_MSForEachTable 'TRUNCATE TABLE ?'
GO
-- enable all  referential integrity again
EXEC sp_MSForEachTable 'ALTER TABLE ? CHECK CONSTRAINT ALL'
GO
Rollback

Msg 4712, Level 16, State 1, Line 1
Cannot truncate table 'dbo.Employee' because it is being referenced by a FOREIGN KEY constraint.

Note :Truncate will reset the Identity column but Delete command doesn't  'So in order to Reset the Identity column for tables having Foreign key Relation ship in the above script
Use the below command


DBCC CHECKIDENT('TableName', RESEED, 0)--0 new reseed starting value

It will show the error message again
click ok

Issue-The lookup table could not be saved due to the following reason(s):•One or more code values in the lookup table contain a code mask separator.

Issue Description -While Creating a LUT(Look Up table) in project Server the LUT Fields were having Values which contains . eg Test.Testing
So adding these type of values in the LUT and saving the LUT was Throwing Error as below Screenshot.






Issue Solution-In Code mask Separator section change the Separator . to * and then save the LUT .The LUT Will get saved .


Note:If your LUT Values contains comma so again you will face the above error changing separator to * will not work you have to Remove comma from your LUT Values.

Running Sum in SQL Server

Running Sum in SQL Server


As a Programmer\developer we are aware of Fibonacci Sequence where the  next number is found by adding up the two numbers before it.
for e.g.-0, 1, 1, 2, 3, 5, 8, 13, 21, 34, ...

In SQL we termed it as Running Total or RunningSum where we will add a new Column that will calculate the Running total.

CREATE TABLE RunningTotal (
   Product nvarchar(100),
   P_Cost int not null
)


INSERT INTO RunningTotal (Product,P_Cost) VALUES ('X',100),('X',150),('X',200),('X',250),('X',300);
INSERT INTO RunningTotal (Product,P_Cost) VALUES ('Y',1000),('Y',1500),('Y',2000),('Y',2500),('Y',3000);
INSERT INTO RunningTotal (Product,P_Cost) VALUES ('Z',10),('Z',15),('Z',20),('Z',25),('Z',30);


So below is the Script calculating Running Sum (Fibonacci Sequence in a New Column ) and  Running Sum Per Product.

Below Script will calculate two below Columns
  1. Total Running Sum-Running Total of  P_cost for all Product irrespective of Product
  2. Running Sum Per Product-Running Total of each Product Calculating Running Sum for Each Product
with cte as
(
Select Product,P_cost,row_number()over(order by (Select 0))as RowNum
 from RunningTotal b
 )
 select Product,P_cost ,(Select Sum(P_cost) as TotalRunningSum from cte a where a.RowNum<=b.rownum    ) as TotalRunningSum,
(Select Sum(P_cost) as TotalRunningSum from cte a where a.RowNum<=b.rownum and a.Product=b.product    ) as RunningSumPerProduct
from cte b
order by Product

Output


NOTE: I have Used row_number()over(order by (Select 0))as RowNum to get row_number of each Row if your table has an identity column then you can use it Replacing this.
