The $list function of SetParm allows you to set the parameter to a list of values. The list of values can be read from either:
You can then use this parameter in an IN statement. Example:
--aqt setparm,parm=custlist,value=$list(xlfile="C:\AQT\Data\testdata.xlsx",sheet=customers,startrow=2)
select * from customers where custcode in ($custlist)
The format of the $list function is:
$list(parm=value,parm=value,parm=value)
Where the following parms can be specified:

The following statement gets a list of values from a query.
By coding the db parameter this query can run against another database. This provides a way of combining data from multiple databases.
--aqt setparm,parm=custlist,value=$list(sql="select cust_code from order_details",db=testdb)
select * from Customer_Details where cust_code in ($custlist)
This example gets the data from a csv file:
$list(file="C:\AQT\Data\customer_details.csv",filedelim=comma,colno=2,startrow=2,quote=y,maxrows=100)
