Query SQL database with Crystal

Question

I have a crystal report that is a production work order from our ERP system Macola ES.  The user enters the work order in Macola then prints it.  The user will input a work order number and the report will populate multiple fields from that work order.  To be specific I am trying to add a field on the report that will display the most recently entered batch number for the item number that is in the work order.
item_no = Field 7 in the report
The t-sql below above achieves what I would like to display on the report when searching the database.  The text after /* and before */ are my comments.
/* Search for the most recent order entered in the ppordfil_sql database
where the item number equals Field7 */
select top 1
cus_name /* Batch number field */
from dbo.ppordfil_sql
where ppordfil_sql.item_no = "Crystal Report Field 7"
order by entered_dt desc

Answer 1

Yes Macola is partner of ours.  However, they are not going to write the Crystal Report for us.  The question I am asking is how I can query an SQL database to display and create a query of the SQL data in my report.  I know how to write the t-sql as shown above.  The field "Crystal Report Field 7" is the field I would like to base my query off.  I was hoping someone could point me in the right direction with using a combination of a command object and a parameter.
