 @PermissionID uniqueidentifier  ,
 @FunctionalDetailsId uniqueidentifier
AS

delete from NSP166_RolePermissionTrans where FunctionalDetailsId=@FunctionalDetailsId
)END

Answer 1

for 的语法if不使用括号。

CREATE PROCEDURE NSP166_DeleteDMSPermission  
 @PermissionID uniqueidentifier  ,
 @FunctionalDetailsId uniqueidentifier
AS  
BEGIN  
    if (SELECT count(PermissionID) AS counts
        FROM NSP166_RolePermissionTrans
        where PermissionID=@PermissionID) > 1
    begin
        delete from NSP166_RolePermissionTrans
            where FunctionalDetailsId=@FunctionalDetailsId
    end
end;
