TSQL SQL to query table using a list of keys from an excel column

I know I have done this in the past but am drawing a complete blank... this should be SO easy.

What I want to do is write TSQL which will read a SQL 2008 table using a list of values in an Excel s/s as the key/where clause.

Example.  I want to query aaa_auto_table where aaa_auto_id = (list of values from excel column).. so this would be a loop, I assume.

How many values are in the Excel column?

You can use the in clause to query multiple values:

select * from aaa_auto_table where aaa_auto_id in (2,4,6,8,10)

KnightEknight,

This is the simplest, however, there are a large number of values in the column, possibly many hundreds or thousands... I know I can do find and replace to put the SQL syntax to us the values in a SQL query, but this is cumbersome.  I know in the past I was able to write or use existing TSQL that would perform the query looping through the list of values.. it may have been a UDF or Stored Procedure also, I don't remember.  

DB-aha, this link appears more of querying within Excel, I need to use a list of values from an excel column to query a SQL table.

The information in the link I provided is only partial for what you need. It involves some creativity in querying the excel sheet as a table and then referring to the column you want to search where ColumnName IN(excelSheet.ColumnName). You can make this easier by importing the excel sheet into a table itself but the IN operator is definitely what you would use in either case. By importing the excel sheet into a table, you can index the column you want to search by which should speed up performance of the query if you are looking for hundreds of thousands of values.
