I have a one table returned from a query that looks something like this:-

EmpName
101
102
103
104
105
106
107

and I want all the Data to stack up like this
101 102 103 104 105 106 107

Note:-The number of records under 'EmpName' is not fixed so in case we have 100 records then it will show the output as pivot up to 100 Columns.

Solution 1

Assuming the fields are varchar, you can write the following code

SQL

DECLARE @ListEmp VARCHAR(MAX)
SELECT @ListEmp = COALESCE(@ListEmp+',' ,'') + EmpName FROM table_name
SELECT @ListEmp

if the fields are numeric, then convert the EmpName to varchar and then append the same..

SQL

DECLARE @EmpName AS TABLE (EmpId Bigint)
DECLARE @Cols AS NVARCHAR(MAX)
INSERT INTO @EmpName
SELECT 101 Union
SELECT 102 Union
SELECT 103 Union
SELECT 104 Union
SELECT 105 Union
SELECT 106 Union
SELECT 107 Union
SELECT 108

SET @Cols =''

SELECT @Cols = @Cols  + CAST(EmpId AS NVARCHAR(MAX)) + ' As [' + CAST(EmpId AS NVARCHAR(MAX))   + '],'
 FROM @EmpName

SET @Cols = 'SELECT ' +  SUBSTRING(@Cols , 1 , LEN(@Cols) - 1 )

EXEC sp_ExecuteSQL @Cols
