Prompting the user to enter Parmeters

Question

I am trying to create a parameter code that prompts the user to ask for input dates between Date1 and Date2 my code is below. How can I correct this ?
WHERE
( OI_ADJUSTMENT_DTL_PAYMENT.RESP_GUAR_NBR=OI_ADJUSTMENT_HDR_PAYMENT.RESP_GUAR_NBR
and OI_ADJUSTMENT_DTL_PAYMENT.SUPP_PAT_NBR=OI_ADJUSTMENT_HDR_PAYMENT.SUPP_PAT_NBR
and OI_ADJUSTMENT_DTL_PAYMENT.ADJ_HDR_ID=OI_ADJUSTMENT_HDR_PAYMENT.ADJ_HDR_ID
and OI_ADJUSTMENT_DTL_PAYMENT.AR_PROC_SET=OI_ADJUSTMENT_HDR_PAYMENT.AR_PROC_SET)
AND OI_REVERSAL_PAY_ADJUSTMENT.REVERSAL_DT BETWEEN @variable('Enter Begin Date MM/DD/CCYY')
AND @variable('Enter End Date MM/DD/CCYY')
AND OI_ADJUSTMENT_DTL_PAYMENT.TABLE_TYPE = 'C'
Thanks!

If you are simply running SQL statements in the worksheet (ie F9), you can use either substitution variables or binds as follows:
Substitution variables:
REVERSAL_DT BETWEEN to_date('&begin_date', 'MM/DD/YYYY') and to_date('&end_date', 'MM/DD/YYYY')
Binds:
REVERSAL_DT BETWEEN to_date(:begin_date, 'MM/DD/YYYY') and to_date(:end_date, 'MM/DD/YYYY')
If you are running your statements as a script (ie F5), you can use substitution variables as follows:
accept begin_date char prompt 'Enter Begin Date [MM/DD/YYYY]:'
accept end_date char prompt 'Enter End Date [MM/DD/YYYY]:'
select ...
from ...
where ...
and REVERSAL_DT BETWEEN to_date('&begin_date', 'MM/DD/YYYY') and to_date('&end_date', 'MM/DD/YYYY')
You can use bind variables when running as a script (F5), but you need to use substitution variables to prompt the user for values, so for your case, there wouldn't be a benefit for using bind variables with F5.
Note that substitution variables are not character values, but rather part of the statement, which is you you need to put the quotes around them when simply using them for character values. Binds on the other hand are treated as character values and we don't need the quotes when using binds.
