Transposing rows and Columns in SQL

I have a MQ-SQL 2005 stored procedure that returns a dataset that is fine except I would like to change the rows to the columns and the columns into the rows. Is there an easy command to do this, or is pivot the only option (which is not easy)?

Thanks,

Hi,
This kind of problems are called Cross Tab Queries and can be solved easily using PIVOTING (a feature from SQL SERVER 2005+).

Here is an example

Pivots with Dynamic Columns in SQL Server 2005[^]

You can even look into

a) Cross-Tab reports in SQL Server 2005[^]

b)Using PIVOT and UNPIVOT[^]

In Sql Server 2000, Pivoting was achieved using Case along with an aggregate function.

Look here

Pivot Table Data in SQL Server 2000 and 2005[^]

However, a few days back I gave a similar kind of answer in Bytes. U can have a look

Month to month yearly results[^]

Hope this helps

Hi,

I need to import 1000s of users to the database. And there values need to be added to 6-7 different tables. Doing it manually would be a nightmare.

I think i can use Cursor for this sort of stuff but never dealt with it in past. Any suggestions?

Thank you .

You can first create a text file containing the user records, if you don't already have one.

Then use your database engine's import function to load the text file in to a table in one step. I can't give you the actual command to do this because I don't know what database engine you are using.

You said you need to load them into many different tables. You may need to modify the text file a bit to load them into these tables because these tables may have different structures.

If an import function is not available for the database engine you are using, you will need to write a small program to insert the records to the tables.

Hope that helps.

Sql server 2008.

i have already imported the excel spreadsheet with all the users info to database. Now for instance there are different table for address field, different table for name field , differnt table for email etc. So my question is do i have to use curser so that i can insert the users value from this temp table to all the necessary table. if yes then how or if not then what's the best way ?

Thank You.

In this case all you need to do is to create these "other tables", and then use "INSERT...SELECT..." query to pull out the necessary fields from the temp table and insert the records to the new tables.

You can also create the tables and insert the records in one step by using the "SELECT...INTO..." statement.

Good luck!

What does 'user' mean here ? Are they database users or your application users (stored in something like Users table) ?

And what database do you use ?

If your database is properly designed and normalized, then simple update statements will work, otherwise you may have to use cursors.

simple update statement works to enter one record by manually writing the details that i need to update but how to go to the next row in the table, get all the details and enter it to specific tables.
So i am not interested in this manual process. Looking for something automatic - say cursor ? but not getting how to use that.

The INSERT and UPDATE statements have a syntax that can be used to update multiple rows in the destination table from values in one or more source tables. The syntax is different for each database.

These are examples for SQL Server:

SQL

INSERT INTO EmployeeMaster (FirstName, LastName, EmpID)
SELECT EmpFirstName, EmpLastName, EmpID
FROM EmployeeTemp
WHERE (...........)

SQL

UPDATE EmployeeMaster
SET EmployeeMaster.FirstName = EmployeeTemp.EmpFirstName,
    EmployeeMaster.LastName = EmployeeTemp.EmpLastName,
    EmployeeMaster.EmpID = EmployeeTemp.EmpID
FROM EmployeeTemp T INNER JOIN EmployeeMaster M ON T.EmpID = M.EmpID
WHERE (...........)

	select 'Hello-World' union all
	select 'code - project codes are good' union all
	select 'hello' union all
	select ' world' union all
