Problem with GETDATE in SQL Stored Procedure

hi all,

i am using a stored procedure where i am using GETDATE to give default value to a field ( @.effectivedate as Datetime = GETDATE)

i am making the SP call in my code .

Dim cmd As System.Data.Common.DbCommand = db.GetStoredProcCommand("sel_TemplateData")

db.AddInParameter(cmd, "@.TemplateID", DbType.Int32, Convert.ToInt32(_templateId))

db.AddInParameter(cmd, "@.State", DbType.String, mrmParams("State").ToString())

db.AddInParameter(cmd, "@.SectionCode", DbType.String, mrmParams("SectionCode").ToString())

Dim ds As DataSet = db.ExecuteDataSet(cmd)

should i need to pass this as a parameter along with other parameter as below ? will it be defaultly taken.

when i try to add this parameter an error is thrown " cannot convert string to datetime .

is the syntax for GETDATE correct.

thanks in Advance

Since Getdate() is the non-deterministic function you can’t assign this function as your default value of the SP parameter.

Try to use the following approach to pick up the current date when there is no explicit value passed for datetime valued parameters.

C

Code Snippet

raete Procedure TestDateParam

(

@.Date as datetime= '1900-01-01'

)

as

Begin

Set @.Date = Case When @.Date = '1900-01-01' Then Getdate() Else @.Date End;

Select @.Date Date

End

Go

Exec TestDateParam --it will use the current date

Exec TestDateParam '1/1/2007' --it will use the passed date value

Could you instead use NULL as your default value? If that is possible then you would not need the set statement but could use the ISNULL or COALESCE function -- something like:

ISNULL(@.Date, getdate())

or

COALESCE(@.Date, getdate())

within the body of your stored procedure

If you are wanting to make @.EffectiveDate an optional parameter for the procedure, I suggest using Kent's suggestion of setting the optional value equal to NULL. It is cleaner than presuming a redefined date means none supplied...

|||In addition to Kent and Arnie you could consider using the syntax:

Create procedure someproc
(
@.SomeDate DATETIME = NULL
)
AS

SELECT
(...Something)
WHERE YourColumn = @.SomeDate OR @.SomeDate IS NULL

But this highly depends on your needs in the logic of the stored procedure.
