    Hi

    I want to display the display all the column values in rows

    imp Note : not all the columns need not refer to single datatype

    eg.,

    Let us suppose that we have a table like below

    col1 | col2 | col3

    --------*---------*----------

    Value 1 | Value 2 | Value 3

    And change it to one that looks like this:

    Name | Value

    -----*---------

    col1 | Value 1

    -----*---------

    col2 | Value 2

    -----*---------

    col3 | Value 3

    Look at PIVOT or a cross tab report.

    It's not an easy thing to do, especially as what do you do with multiple rows? Are they extended to the right?

    It's rather a task for UNPIVOT...

    Here's a sample (pretty much straight off BOL and slightly modified):

    DECLARE @t TABLE (col1 VARCHAR (10), col2 VARCHAR (10), col3 VARCHAR (10))

    INSERT INTO @t VALUES ('Value 1', 'Value 2', 'Value 3')

    SELECT * FROM @t

    SELECT Name, Value

    FROM

    (SELECT col1, col2, col3

    FROM @t pvt) p

    UNPIVOT

    (Value FOR Name IN

    (col1, col2, col3)

    )AS unpvt

    /* result set:

    Name Value

    col1 Value 1

    col2 Value 2

    col3 Value 3

    */

    Note: I'm sure Jeff's going to show up presenting a "PIVOT-phrase-free" solution but that's all I could come up with as a quick fix...

    Edit: spelling fixed

    Hi,

    Just cast\convert all the cols to same data type

    DECLARE @t TABLE (col1 VARCHAR (10), col2 int, col3 CHAR (10))

    INSERT INTO @t VALUES ('Value 1', 2, 'Value 3')

    SELECT * FROM @t

    SELECT Name, Value

    FROM

    (SELECT col1, cast(col2 as varchar(10)) as col2, cast(col3 as varchar(10)) as col3

    FROM @t pvt) p

    UNPIVOT

    (Value FOR Name IN

    (col1, col2, col3)

    )AS unpvt

    /* result set:

    Name Value

    col1 Value 1

    col2 2

    col3 Value 3

    */

    This is just another good example of how important sample data are that actually do show your current scenario....

    Kupy made the required adjustment (assuming, that varchar(10) is the type that would match your data...).
