I have a user_roles table in which the user can have more than one active role from one type (RoleID) but in more than one region (RegionID) as in the sql table code, i want to get all the users who have more than one active role in more than one type.
table creation code:
CREATE TABLE [dbo].[UserRole](
[ID] [int] IDENTITY(1,1) NOT NULL PRIMARY KEY,
[UserID] [int] NOT NULL,
[RoleID] [int] NOT NULL,
[RegionID] [int] NULL,
[IsActive] [bit] NOT NULL )

I have system versioned Customer table and need to track if admin user deleted the row ('Tesla') from the table.
CustomerHistory table do get new row for 'Tesla', but it does not explicitly tell if row has been updated or deleted.
I would need advice to create SELECT/INSERT SQL query, which compared Customers and CustomerHistory to check which row has been deleted and insert the row ('Tesla') to CustomersDeleted table.
I have System versioned table:
CREATE TABLE [sales].[Customers](
[Customer_PK] [int] IDENTITY(1,1) NOT NULL,
[Customer_Id] [smallint] NULL,
[Customer_Name] [nvarchar](150) NULL,
) ON [PRIMARY]
GO
It has value '1','100','Tesla' and '2','200','Ford'.
Admin user will deleted 'Tesla' row.
I have History versioned table:
CREATE TABLE [sales].[CustomersHistory](
[Customer_PK] [int] NOT NULL,
[Customer_Id] [smallint] NULL,
[Customer_Name] [nvarchar](150) NULL,
) ON [PRIMARY]
GO
I have third table where I would like to insert rows ('Tesla') that has been removed from Customer table.
CREATE TABLE [sales].[CustomersDeleted](
[Customer_PK] [int] NOT NULL,
[Customer_Id] [smallint] NULL,
[Customer_Name] [nvarchar](150) NULL,
[Deleted_time] [datetime2](7) NULL
) ON [PRIMARY]

I am using RDLC for reports loaded into ASP.NET MVC.
I tried to filter the results between two dates, but when I type the following query below I get the following error:
"the new command text returns data with schema different from the schema of the main query. Check your query's command text if this is not desired."
Can you help me on how to do it?

I am trying to join two tables by using SQL query by using single parameters. I have two tables student and student job record and I want to join this two table into single a single based on ID.
Student profile table.
CREATE TABLE [dbo].[Student_Profile]
(
[StudentID] [int] IDENTITY(1,1) NOT NULL,
[First_Name] [varchar](50) NULL,
[Last_Name] [varchar](50) NULL,
[Email] [varchar](500) NULL,
[Qualifactions] [varchar](50) NULL,
[Name_Of_Instatutions] [varchar](50) NULL,
[City] [varchar](50) NULL,
[Country] [varchar](50) NULL,
[Contract] [varchar](50) NULL
) ON [PRIMARY]
Here is the student job profile table.
CREATE TABLE [dbo].[Student_Job_Record]
(
[Record_ID] [int] IDENTITY(1,1) NOT NULL,
[StudentID] [int] NULL,
[Total_Hours_Work] [varchar](50) NULL,
[Pay_Rate] [varchar](50) NULL,
[Total_Amount_Paid] [varchar](500) NULL
) ON [PRIMARY]
I am using a stored procedure to display the data into gridview. Here is the stored procedure code.
CREATE PROCEDURE [dbo].[spGetStudentsDeatilsByID]
#ID int
AS
BEGIN
SELECT
Student_Profile.First_Name, Student_Profile.Last_Name,
Job_Profile.Title, Job_Profile.Location,
Job_Profile.Type_Contract, Job_Profile.Salary
FROM
Student_Profile, Job_Profile
WHERE
Student_Profile.StudentID = #ID
AND Job_Profile.StudentID = #ID
END
I want to display and join this two table into gridview based on studentID. But when I enter the student Id and click the submit button, nothing is displayed.
Here is the screen shot when I run the applications.
Try the following. If you do not have StudentID in Job_Profile then you can use LEFT JOIN.
Create proc [dbo].[spGetStudentsDeatilsByID]
#ID int
as
Begin
SELECT
sp.First_Name,
sp.Last_Name ,
jp.Title,
jp.Location,
jp.Type_Contract,
jp.Salary
FROM Student_Profile sp
LEFT JOIN Job_Profile jp
ON sp.StudentID = jp.StudentID
WHERE sp.StudentID =#ID
End
GO
I'm recording all insert and update on TaskDetail table using a trigger,Now I want to assign multiple staff to a task, But if staff id stored in different child table how can I track audit history, I have considered storing staff id as comma separated values but child table is always a good option.
In TaskStaff table multiple staff will have same taskId
CREATE TRIGGER [dbo].[TaskDetail_History_Trigger]
ON [dbo].[TaskDetail]
FOR Insert,UPDATE
AS
INSERT INTO TaskHistory SELECT * FROM inserted

I am designing user registration table with below columns.
CREATE TABLE [dbo].[NCT_UserRegistration]
(
[User_Id] [int] IDENTITY(1,1) NOT NULL,
[User_EmailId] [varchar](255) NULL,
[User_Password] [varchar](512) NULL,
[User_Name] [varchar](255) NULL,
[User_MobileNum] [varchar](20) NULL,
[User_Status] [varchar](15) NULL,
[User_Role] [varchar](20) NULL,
[User_CreatedDate] [timestamp] NULL,
[User_UpdatedDate] [datetime] NULL,
[Name] [varchar](30) NULL
)
My requirement for the status and role as below.
status VARCHAR(15) Index, Enumeration of ENABLED, DISABLED.
role VARCHAR(20) Enumeration of SUPER_ADMIN and PROJECT_ADMIN
What I understood from above is status should take only Enabled or Disabled and same with role also. How can I design my table to make sure it takes only those two values? Also is there any way for example if I supply 1 then it is ENABLED and 0 for DISABLED.
May I get some ideas here? Any help would be appreciated. Thank you
You need to use CHECK CONSTRAINT to limit to specific values
CREATE TABLE [dbo].[NCT_UserRegistration](
[User_Id] [int] IDENTITY(1,1) NOT NULL,
[User_EmailId] [varchar](255) NULL,
[User_Password] [varchar](512) NULL,
[User_Name] [varchar](255) NULL,
[User_MobileNum] [varchar](20) NULL,
[User_Status] [varchar](15) NULL CONSTRAINT chk_Status CHECK ([User_Status] IN ('ENABLED', 'DISABLED')),
[User_Role] [varchar](20) NULL CONSTRAINT chk_Role CHECK ([User_Role] IN ('SUPER_ADMIN','DISABLED')),
[User_CreatedDate] [timestamp] NULL,
[User_UpdatedDate] [datetime] NULL,
[Name] [varchar](30) NULL
)
For enumeration you will have to handle at front end or while retriving values from table which is an extra step.
SELECT CASE WHEN [User_Status] = 1 THEN 'ENABLED' WHEN [User_Status] = 0 THEN 'DISABLED' END As UserStratus
FROM [dbo].[NCT_UserRegistration]
Can you try adding constraint as below for status field. If its working then apply the same to ROLE field.
alter table NCT_UserRegistration
add (STATUS VARCHAR(15) default 'ENABLED',
constraint conSTATUS check (STATUS in ('ENABLED', 'DISABLED')))
There are two possible approaches.
Check constraints - #mh2017 has explained this well in his answer.
Looking at the conversation that seems to fit your requirements better, but just for the sake of sharing idea, I will mention -
Foreign key constraint (FK)- If it is acceptable to modify the User_Status and User_Role columns to be of type tinyint (or similar number type), you can store just the ids in these and create enumeration (aka mapping tables) to store what the ids represent.
Create FK on User_Status and User_Role in NCT_UserRegistration to refer to the enumeration tables.
FKC ensures that the referring column (User_Status and User_Role in NCT_UserRegistration) cannot have value other than those listed in the referred to column (the respective id columns in the enumeration tables)
This Foreign key vs check constraint for integrity post also describes few benefits of using FK over check constraint
Here is a sample code showing foreign key approach
CREATE TABLE [dbo].[NCT_UserRegistration](
[User_Id] [int] IDENTITY(1,1) NOT NULL,
[User_EmailId] [varchar](255) NULL,
[User_Password] [varchar](512) NULL,
[User_Name] [varchar](255) NULL,
[User_MobileNum] [varchar](20) NULL,
[User_Status] tinyint NULL, -- I changed this from varchar to tinyint
[User_Role] tinyint NULL, -- I changed this from varchar to tinyint
[User_CreatedDate] [timestamp] NULL,
[User_UpdatedDate] [datetime] NULL,
[Name] [varchar](30) NULL
)
create table StatusEnumeration
(
StatusId tinyint,
Description varchar(10)
constraint pk_StatusEnumeration__StatusId primary key clustered (StatusId)
)
insert into StatusEnumeration(StatusId, Description)
values
(0, 'Disabled'),
(1, 'Enabled')
create table RoleEnumeration
(
RoleId tinyint,
Description varchar(20)
constraint pk_RoleEnumeration__RoleId primary key clustered (RoleId)
)
insert into RoleEnumeration(RoleId, Description)
values
(0, 'SUPER_ADMIN '),
(1, 'PROJECT_ADMIN')
alter table NCT_UserRegistration
add constraint fk_NCT_UserRegistration__StatusEnumeration_StatusId foreign key (User_Status)
references StatusEnumeration (StatusId)
go
alter table NCT_UserRegistration
add constraint fk_NCT_UserRegistration__RoleEnumeration_RoleId foreign key (User_Role)
references RoleEnumeration (RoleId)
go
