Question

Need the solution to solve taking string from the database and replacing the parameter.

Here are the sample queries I used to understand more:

--Create Table Table1
--(
--Id int primary key identity(1,1),
--Data varchar(max)
--)

--Create Table Table2
--(
--Id int primary key identity(1,1),
--SampleData varchar(max)
--)

Delete From Table1
GO

Delete From Table2
Go

insert into Table2 (SampleData) values ('How r u ''+@i+''. ')

Declare @i int = 100
Declare @TempSampleData varchar(max) = NULL

While(@i > 0)
begin
    Set @TempSampleData = (select SampleData from Table2)
    insert into Table1 (Data ) values (@TempSampleData)
    insert into Table1 (Data) values ('How r u '+Cast(@i as varchar(500))+'.')
    set @i = @i - 1
End

–Output

Id  Data
103 How r u '+@i+'. --Needed output here is How r u 100.
104 How r u 100.
105 How r u '+@i+'. 
106 How r u 99.
107 How r u '+@i+'. 
108 How r u 98.
109 How r u '+@i+'. 
110 How r u 97.
111 How r u '+@i+'. 

Answer 1

How about something like this in your loop:

INSERT INTO Table1 (Data)
SELECT REPLACE(SampleData, '@i', CAST(@i AS VARCHAR(500)))
FROM Table2
