Question

How can I get a list of values (one or more) used in the WHERE filter of stored procedures and functions in SQL Server?
How can get a list of values as shown (highlighted) in the sample stored procedure below?
ALTER PROC [dbo].[sp_LoanInfo_Data_Extract] AS
SELECT   [LOAN_ACCT].PROD_DT,
              [LOAN_ACCT].ACCT_NBR, 
              [LOAN_NOTE2].OFCR_CD, 
              [LOAN_NOTE1].CURR_PRIN_BAL_AMT, 
              [LOAN_NOTE2].BR_NBR,
INTO #Table1
FROM
                dbo.[LOAN_NOTE1],
                dbo.[LOAN_NOTE2],
                dbo.[LOAN_ACCT]
WHERE
                [LOAN_ACCT].PROD_DT = [LOAN_NOTE1].PROD_DT
                and
                [LOAN_ACCT].ACCT_NBR = [LOAN_NOTE1].ACCT_NBR
                and
                [LOAN_NOTE1].PROD_DT = [LOAN_NOTE2].PROD_DT
                and
                [LOAN_NOTE1].MSTR_ACCT_NBR = [LOAN_NOTE2].MSTR_ACCT_NBR
                and
                [LOAN_ACCT].PROD_DT = '2015-03-10'
                and
                [LOAN_ACCT].ACCT_STAT_CD IN
('A','D')
                and
                [LOAN_NOTE2].LOAN_STAT_CD IN
('J','Z')

Hi LenFinkel,
May I know what is purpose of this requirement, as olaf said,you may parse the T-SQL code (or the execution plan), which is not that easy.
I have noticed that the condition values in your Stored Procedure(SP) are hard coded and among them there is a date values, I believe some day you may have to alter the SP when the date expires. So why not declare 3 parameters of the SP instead hard coding?
For multiple values paramter you can use a
table-valued parameter. Then there's no problem getting the values.
If you could elaborate your purpose, we may help to find better workaround.
