How to Pull Data That Meets 2 Criteria For the Same Column

How to Pull Data That Meets 2 Criteria For the Same Column

(OP)
Hi,
I'm fairly new to Crystal and SQL. I'm wanting to pull a listing of people who meet 2 of the types of criteria for the same column by using a Crystal Report.

Let's say we have a column in our database called Contact Type. This column contains how a customer has contacted us. We want a listing of those people who have contacted us by phone with the abbreviation PHO and by email with the abbreviation EMA. We don't want to pull a listing of customers who has done either but instead who has done both.

Thanks in advance for your assistance!

I'm using Crystal Reports XI R2.

RE: How to Pull Data That Meets 2 Criteria For the Same Column

Try this:
  1. Group by client
  2. Create a formula like:

    CODE

    If	{Table.Contact_Type} = 'PHO'
    Then 	1 
    Else
    If	{Table.Contact_Type} = 'EMA'
    Then 	3
    Else	2 
  3. Add a Group selection Formula like:

    CODE

    DistictCount({Table.Contact_Type}, {Table.ClientGroup}) > 1 and
    Maximum({Table.Contact_Type}, {Table.ClientGroup}) = 3      and
    Minimum({Table.Contact_Type}, {Table.ClientGroup}) = 1 
Hope this helps

Cheers
Pete

RE: How to Pull Data That Meets 2 Criteria For the Same Column

If you want the list of who has used both methods, not just one or the other, you'll have to do the following:

1. Add a second copy of the table that contains the contact type information to the report. Crystal will throw a warning asking if you want to "alias" the table and then add it with "_1" on the end of the table name.
2. Inner join from the original copy of the table (I'll call this "MyTable" in this example) to the aliased table ("MyTable_1")
3. Apply all of your original selection criteria to MyTable except the contact type.
4. Add the following to the selection criteria:
{MyTable.Connection_Type} = 'PHO' and
{MyTable_1.Connection_Type} = 'EMA'

Because of the inner join, this will only show people who have used both methods. However, you may need to turn on "Select Distinct Records" on the Database menu and you may have to do some additional grouping to make sure that you're not showing duplicate data.
