I would like to obtain results using the 'like' word but I want it to ignore the case in the results.

For example
select * from table1 where column1 like 'aBcD'
should return all the rows where column1 is ABCD, abcd, etc.

thanks,
Anu

If you are using the default Charset SQL_Latin1_General_CP1_CI_AS the ci stands for case insensitive.

Currently my query
select * from table1 where column1 like 'ABCD%' returns only the 'ABCD' not 'abcd' .

Is it possible to do in SQL?

You can upper everything and give it a try, something like:

select * from table1 where UPPER(column1) like UPPER('ABCD%')

That worked but the query took a long time to execute. It took a minute instead of a second.

Do we have any other solution?

That is because you wrapped the column1 with a function. Try it with COLLATE. Using aaron's Charset:

SELECT *
FROM table1 
WHERE column1 COLLATE SQL_Latin1_General_CP1_CI_AS LIKE 'ABCD%';

If column1 has index on it, doing UPPER(column1) will prevent that index from being used.
