I have a table with 2 varchar columns. One of this columns has to store the name of an item in portuguese. The problem is when i make an insert, appears some strange letters. Even if i make an update, they still appear.
This is my table definition:
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE TABLE [dbo].[Items](
[idItem] [int] IDENTITY(1,1) NOT NULL,
[name_es] [varchar](100) NULL,
[name_pt] [varchar](100) NULL,
CONSTRAINT [Items] PRIMARY KEY CLUSTERED
(
[idItem] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]
GO
And this is what happens
Any idea?
You’re using VARCHAR which doesn’t like non-English characters so try and use the data type NVARCHAR instead

I want to create this table with the following constrains, is it possible to do with SQL Server Management Studio?
Id
ProductId [Nullable column]
CompanyId [Nullable column]
Username [unique for every productId - IF DeletedAt is not NULL]
Identifier [Nullable column] [unique for every companyId - IF DeletedAt is not NULL]
DeletedAt [Nullable column]
Update:
My table create query is the following:
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE TABLE [dbo].[User](
[Id] [int] IDENTITY(1,1) NOT NULL,
[ProductId] [int] NULL,
[CompanyId] [int] NULL,
[Username] [nvarchar](max) NOT NULL,
[Identifier] [nvarchar](max) NULL,
[DeletedAt] [datetime2](7) NULL,
CONSTRAINT [PK_User] PRIMARY KEY CLUSTERED
(
[Id] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF,
ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY] TEXTIMAGE_ON [PRIMARY]
GO
You'll want to use a unique filtered index. Here you go for the table:
/****** Object: Table [dbo].[the_table] Script Date: 7/26/2018 4:04:00 PM ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE TABLE [dbo].[the_table](
[id] [int] NOT NULL,
[productid] [varchar](50) NULL,
[companyid] [varchar](50) NULL,
[username] [varchar](50) NULL,
[identifier] [varchar](50) NULL,
[deleteat] [varchar](50) NULL,
CONSTRAINT [PK_the_table] PRIMARY KEY CLUSTERED
(
[id] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]
GO
And the index for username:
SET ANSI_PADDING ON
GO
/****** Object: Index [UIDX_USERNAME] Script Date: 7/26/2018 4:03:31 PM ******/
CREATE NONCLUSTERED INDEX [UIDX_USERNAME] ON [dbo].[the_table]
(
[username] ASC
)
WHERE ([DELETEAT] IS NOT NULL)
WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, SORT_IN_TEMPDB = OFF, DROP_EXISTING = OFF, ONLINE = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
GO
It would be the same index logic for the other column, but I don't want to clutter this answer by posting more! I would not mess around with putting the logic in triggers or stored proc's, bad data could still sneak in. If you keep nice constraints, nobody can clutter your data up :)
You can use filtered indexes. The syntax looks like this:
create unique index unq_thetable_username on the_table(username)
where deleteAt is not null;
I don't know if you can point-and-click your way to this solution. I would just write the logic as above.
Create a unique index on ProductId and Username, and use a where clause to restrict that index to WHERE DeletedAt IS NOT NULL. Answer showing an example of a unique filtered index.
You may also need the clause AND ProductId IS NOT NULL, although that wasn't stated as a requirement, but since that column is nullable you ought to think about this.
Similar for Identifier.
You might also want to think about the value of a table where it is valid to have a row where all the columns except Id are null...
I am trying to create replica of my database from SQL server to another.
For that I am generating script from original server and trying to run in another server. I've created database manually with the same name.
Here is the screenshot of original database
When I generate script, following script is created which I am trying in another server

When I try to run this script, I get following error
The specified schema name "common" either does not exist or you do
not have permission to use it.
I don't know what is the meaning of common here.Thanks
Your tables are 'grouped' (for want of better word) in schemas (google for it). You should run
CREATE SCHEMA common
And likewise for all other schemas.
How do you add the following default value to a sql database table?
01
I have tried various datatypes but the 0 keeps disappearing. I haven't even been able to find an example on the exchange or google but I assume this is very straight forward and I am being a numpty!!!
I have tried numeric/integer/varchar without luck. Thanks.
create table MyTable (Id int, Value varchar(100) not null default('01'))
Insert into MyTable (Id) values (1)
Select Value
From MyTable
will be '01'

Another option could be:
Open your Table Designer and you will see something like this:
If you prefer code:
USE ["name of your dataBase"]
GO
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE TABLE [dbo].[Table_1](
[id] [int] IDENTITY(1,1) NOT NULL,
[sample02] [nvarchar](50) NOT NULL,
[sample03] [nvarchar](50) NULL,
CONSTRAINT [PK_Table_1] PRIMARY KEY CLUSTERED
(
[id] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY] ON [PRIMARY]
GO
ALTER TABLE [dbo].[Table_1] ADD CONSTRAINT [DF_Table_1_sample02] DEFAULT ('01') FOR [sample02]
GO
And finally, you can visit this Microsoft post: Specify Default Values for Columns
I got table "Functions" with Function_ID {PK} and I want another table "Hierarchy" with Hierarchy_ID {PK} which defines tree structure of functions so i need one Function_ID from Function table AS Parent_ID and one Function_ID AS Child. my question is how i can use two primary keys from another table to make it together as Foreign key
I am using SQL Server 2012 and the Management Studio
Many Thanks
Actually you just need to add a ParentFunction_ID column in the Functions table.
You don't need another table if your structure is indeed a tree.
Then make the ParentFunction_ID to be a FK to the same table Functions.
So ParentFunction_ID (FK) would be pointing to Function_ID (PK).
The only record which has ParentFunction_ID NULL would be the root of your tree.
Here is some sample code:
USE [test]
GO
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
SET ANSI_PADDING ON
GO
CREATE TABLE [dbo].[Functions](
[Function_ID] [int] IDENTITY(1,1) NOT NULL,
[FunctionCode] [varchar](max) NULL,
[ParentFunction_ID] [int] NULL,
CONSTRAINT [PK_Functions] PRIMARY KEY CLUSTERED
(
[Function_ID] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]
GO
SET ANSI_PADDING OFF
GO
ALTER TABLE [dbo].[Functions] WITH CHECK ADD CONSTRAINT [FK_Functions_Functions] FOREIGN KEY([ParentFunction_ID])
REFERENCES [dbo].[Functions] ([Function_ID])
GO
ALTER TABLE [dbo].[Functions] CHECK CONSTRAINT [FK_Functions_Functions]
GO
Name your Functions table a Function table. AFAIK using
plurals for table names is not really a good practice.
So you can do this.

my sql table:
CREATE TABLE [dbo].[PayrollParameter]

[PRIMARY]
)
ON [PRIMARY]
GO
the database already contain records; I want to alter the table to set the default value of IsFixedDaysInMonth to Checked if NumberOfDaysInMonth!=0
How can i do this?
CREATE DEFAULT needs a constant value as the default
Is an expression that contains only constant values (it cannot include
the names of any columns or other database objects).
The only ways I know to do what you want would be to use a trigger or insert using a stored procedure.
