T-SQL SQL Server - Stored Procedure with parameter

Please, the first TSQL works FINE, the second does not. I guess it must be a simple mistake, since I am not used to T-SQL. Thank you for the answers. R Conte.

Try

[rconte].[spPesquisasPorStatus] ( @pPesStatus = N'dis')

or simply

spPesquisasPorStatus N'dis'

Ok, for my second attempt, I went ahead and created the table and the stored procedure in my own local db!

Your code works flawlessly, as you can see in my screenshot. Are you doing something silly, like running the wrong stored procedure accidentally, or maybe running it on the wrong database (this happens to everyone - don't feel bad!)?

Or maybe I am doing something wrong? But I made a table like I imagine yours to be, and used your exact stored procedure. It worked fine with and without the 'dis' parameter. I hope this helps!

You might need to start from scratch on a new database in a new session just for a "sanity check"

When it asks you for the parameters in the VS dialog box, simply put the string in the Value column, do not put it in quotes or with an N in front of it.

i.e. dis rather than N'dis'

Visual Studio automatically puts strings in the correct format when you select "Execute Stored Procedure..." from the right click menu.
