Stored Procedure Conversion Error with Dynamic Date Parameter but Not with Literal

Data and Databases
1

Using a dynamic datetime parameter in a stored procedure triggers conversion errors, while hardcoded strings work fine. For instance:

DECLARE @tempDate DATETIME = CAST('2022-08-15 10:00:00' AS DATETIME);
EXEC dbo.spProcessRecord @Message = 'Example', @RecordDate = @tempDate, @ColorCode = 'Red', @UserName = 'Alice';

hey guys, im a bit confusd about dynamic parmas vs literal values. do u think trying explicit convert might fix it? maybe the issue lies in regional settings. what have you alll experienced? curious to hear more insights.

had a similiar issue! fixed it by checking the stored proc defn & making sure both sides had the same datetime type. giving a proper cast early on solved it for me. might be worth a try.

Based on my experience, conversion errors with dynamic datetime parameters are often attributable to subtle differences in how SQL Server handles implicit versus explicit conversion. When passing a literal, the database uses a standard interpretation, but dynamic parameters might trigger different conversion rules, particularly when regional settings or session-specific formats are involved. I resolved this issue by carefully verifying that the stored procedure’s parameter type matched the dynamically provided value. Ensuring that any conversion is explicitly managed through CAST or CONVERT in the calling code typically resolves such conflicts.

hey guys, im wonderin if checkin session settings or even order of params might be contributin? might be a config mismatch. anyone tried adjustin settings or a diff approach to catch subtle errors? curious to hear your take.
