I want to get the data from tables for the user specified columns.

What I have tried:

--dummy table
CREATE TABLE #tbEmployeeMaster (EmployeeId INT IDENTITY(1,1), EmployeeName VARCHAR(100), FatherName VARCHAR(100), MotherName VARCHAR(100), Age INT)

INSERT INTO #tbEmployeeMaster (EmployeeName ,FatherName , MotherName, Age) VALUES ('Aman', 'Rakesh', 'Anita', 22)
INSERT INTO #tbEmployeeMaster (EmployeeName ,FatherName , MotherName, Age) VALUES ('Sunil', 'Sandeep', 'Kavita', 22)

DECLARE @SelectedColumns VARCHAR(500)='EmployeeName,Age';
--Note: User can select above columns in any order e.g. Age,EmployeeName

--I tried dynamic sql as follows.
DECLARE @SQL VARCHAR(2000)
SET @SQL = 'SELECT ' + @SelectedColumns + ' FROM #tbEmployeeMaster'
EXEC(@SQL) --it works

--I want to insert the data into temporary table using the syntax below so that i can use that further.But IT did not work. I know table varible can not be used here because we don't know the column order.

SELECT * INTO #tbEmp EXEC(@SQL)

Solution 1

You can't use a table variable anyway because of the scope of the procedures.

You have to add the 'select into' into the query:

SQL

DECLARE @SQL VARCHAR(2000)
SET @SQL = 'SELECT ' + @SelectedColumns + ' INTO #tbEmp FROM #tbEmployeeMaster' 
EXEC(@SQL)

using select-into self defines the table structure, as i'm sure you already know.

I'm afraid your solution will not work as you envision. You will need to create the #tbEmp /schema ahead of time before executing the Stored Procedure. Or use the OPENROWSET function. or write the whole solution using dynamics SQL .

SQL

CREATE TABLE #tbEmp (EmployeeName VARCHAR(100), Age INT)
...
INSERT INTO #tbEmp EXEC(@SQL)
