I have created a table with the following set of data

CREATE TABLE [dbo].[RiskTable]
(
    [ReqID] [int] NOT NULL,
    [ModuleName] [nvarchar](50) NULL,
    [CreatedDate] [datetime2](7) NULL,
    [AssociatedRisk] [nvarchar](50) NULL
)

I have a stored procedure that satisfies the following condition:

  1. If I'm giving model = saa, start_date = 2023-01-01, end_date = 2023-02-10, I want it to show me the total number of risks (low, Medium, High, and Critical) of those particular months (2023-01-01(Jan), 2023-02-10(Feb)) of the model 'saa'.
  2. If I'm giving model = Null, start_date = 2023-04-01, end_date = 2023-05-11, I want it to show me the total number of risks (low, Medium, High, and Critical) of those particular months (2023-04-01(Apr), 2023-05-11(May)) of all the models. output I'm getting for my previous condition: | Model | Month | Risk | Total no. of risk| |------ |--------- |------- |------------------ | |All |Apr or 04 |Low | 1 | |All |Apr or 04 |Medium | 0 | |All |Apr or 04 |High | 1 | |All |Apr or 04 |Critical| 0 | |All |May or 05 |Low | 0 | |All |May or 05 |Medium | 1 | |All |May or 05 |High | 0 | |All |May or 05 |Critical| 0 |
CREATE PROCEDURE Month_base_global
                @model varchar(20),   
                @start_date date,
                @end_date date
    AS
    BEGIN
    IF @model = 'ALL'
        BEGIN
          SELECT 'ALL' as [Module], ac.[Month], ac.AssociatedRisk as Risk, count(ri.ModuleName) as   'Total risks'
        FROM (
          SELECT DISTINCT convert(varchar(7), r.CreatedDate, 126) as [month], a.AssociatedRisk,  m.ModuleName
          FROM RiskTable r
          FULL OUTER JOIN (
            SELECT DISTINCT AssociatedRisk
            FROM RiskTable
          ) as a on a.AssociatedRisk is not null

        ) as ac
        LEFT JOIN RiskTable ri on ac.[month] = convert(varchar(7), ri.CreatedDate, 126)
                               and ac.AssociatedRisk = ri.AssociatedRisk
                               and ac.ModuleName = ri.ModuleName
        GROUP BY ac.[month], ac.AssociatedRisk
        ORDER BY ac.[month], ac.AssociatedRisk desc
    END
    ELSE
        BEGIN
        SELECT @model as [Module], ac.[Month], ac.AssociatedRisk as Risk, count(ri.ModuleName) as 'Total risks'
        FROM (
          SELECT DISTINCT convert(varchar(7), r.CreatedDate, 126) as [month], a.AssociatedRisk, m.ModuleName
          FROM RiskTable r
          FULL OUTER JOIN (
            SELECT DISTINCT AssociatedRisk
            FROM RiskTable
          ) as a on a.AssociatedRisk is not null
          FULL OUTER JOIN (
             SELECT DISTINCT ModuleName
             FROM RiskTable
          ) as m on m.ModuleName = @model
            WHERE r.CreatedDate between DATEADD(mm, DATEDIFF(mm, 0, @start_date), 0) and eomonth(@end_date)
        ) as ac
        LEFT JOIN RiskTable ri on ac.[month] = convert(varchar(7), ri.CreatedDate, 126)
                               and ac.AssociatedRisk = ri.AssociatedRisk
                               and ac.ModuleName = ri.ModuleName
        GROUP BY ac.ModuleName, ac.[month], ac.AssociatedRisk
        ORDER BY ac.[month], ac.AssociatedRisk desc
    END
    END
    Exec Month_base_global 'ALL' , '2022-02-01', '2023-01-28'

Now I have few more condition Exec Month_base_global 'ALL' , null, '2023-01-28'

3.If Model = ALL or any particular model like 'Saa' or 'IDA' or anything, then Start_date = null and end_date = 2023-01-28. It has to fetch all the records from the start in the table of that particular model or ALL.

Exec Month_base_global 'ALL' , '2022-12-03', null

4.If If Model = ALL or any particular model like 'Saa' or 'IDA' or anything, then Start_date = 2022-12-03 and end_date = null means it has to show the records from that particular start_date to the till date(uptodate).

Exec Month_base_global 'ALL' , null, null

5.If Model = ALL or any particular model like 'Saa' or 'IDA' or anything, start_date = null, end_date = null means it has to show all the records from the start of the createddate to the till date(uptodate).

can someone help me with this? Thanks

You can accomplish this by Initializing start date to a previous date, such as '1970-01-01' and end date to '2030-12-31' :

CREATE PROCEDURE Month_base_global
                @model varchar(20),   
                @p_start_date date,
                @p_end_date date
AS
BEGIN
DECLARE @start_date date;
DECLARE @end_date date;
    SET @start_date = @p_start_date ;
    SET @end_date = @p_end_date ;
    IF (@p_start_date IS NULL)
    BEGIN
       SET @start_date = '1970-01-01';
    END

    IF (@p_end_date IS NULL)
    BEGIN
       SET @end_date = '2030-12-31';
    END

    IF @model = 'ALL'
        BEGIN
          SELECT 'ALL' as [Module], ac.[Month], ac.AssociatedRisk as Risk, count(ri.ModuleName) as   'Total risks'
        FROM (
          SELECT DISTINCT convert(varchar(7), r.CreatedDate, 126) as [month], a.AssociatedRisk,  m.ModuleName
          FROM RiskTable r
          FULL OUTER JOIN (
            SELECT DISTINCT AssociatedRisk
            FROM RiskTable
          ) as a on a.AssociatedRisk is not null
          FULL OUTER JOIN (
             SELECT DISTINCT ModuleName
             FROM RiskTable
          ) as m on m.ModuleName is not null
          WHERE (r.CreatedDate) between (@start_date) and (@end_date) 
        ) as ac
        LEFT JOIN RiskTable ri on ac.[month] = convert(varchar(7), ri.CreatedDate, 126)
                               and ac.AssociatedRisk = ri.AssociatedRisk
                               and ac.ModuleName = ri.ModuleName
        GROUP BY ac.[month], ac.AssociatedRisk
        ORDER BY ac.[month], ac.AssociatedRisk desc
    END
    ELSE
        BEGIN
        SELECT @model as [Module], ac.[Month], ac.AssociatedRisk as Risk, count(ri.ModuleName) as 'Total risks'
        FROM (
          SELECT DISTINCT convert(varchar(7), r.CreatedDate, 126) as [month], a.AssociatedRisk, m.ModuleName
          FROM RiskTable r
          FULL OUTER JOIN (
            SELECT DISTINCT AssociatedRisk
            FROM RiskTable
          ) as a on a.AssociatedRisk is not null
          FULL OUTER JOIN (
             SELECT DISTINCT ModuleName
             FROM RiskTable
          ) as m on m.ModuleName = @model
            WHERE r.CreatedDate between DATEADD(mm, DATEDIFF(mm, 0, @start_date), 0) and eomonth(@end_date)
        ) as ac
        LEFT JOIN RiskTable ri on ac.[month] = convert(varchar(7), ri.CreatedDate, 126)
                               and ac.AssociatedRisk = ri.AssociatedRisk
                               and ac.ModuleName = ri.ModuleName
        GROUP BY ac.ModuleName, ac.[month], ac.AssociatedRisk
        ORDER BY ac.[month], ac.AssociatedRisk desc
    END
END
