I have a table with 2 million records. I want copy some of them (beginning from CreationDate) with all their dependencies into an archive table that has the same structure and then delete the copied rows from the main table. I know how to copy all data via "Generate scripts" and then insert into archive table, but how to copy only some rows? What I have already done: used "Generate script" to build archive table similar to main.
CREATE TABLE [dbo].[ArchiveTable]
([Id] [int] IDENTITY(1,1) NOT NULL,
[UserId] [int] NOT NULL, – ForeignKey
[CreationDate] [datetime] NOT NULL,
[StatusId] [int] NOT NULL, – ForeignKey
[ProductId] [int] NULL, – ForeignKey}
Since you are on the same DB you can use this:
INSERT INTO [dbo].[ArchiveTable] (Id,UserId,CreationDate,StatusId,ProductId)
SELECT Id,UserId,CreationDate,StatusId,ProductId
FROM YourTable
WHERE condition

I am using Microsoft SQL Server 2014 Express as a database server.
I have the following two tables between which I want to create PK-FK relationship.
CREATE TABLE [dbo].[Account]
(
[ID] [int] IDENTITY(1,1) NOT NULL,
[ACCOUNTNAME] [nvarchar](max) NOT NULL,
[ACCOUNTTYPE] [int] NOT NULL,
[CREATE_TIMESTAMP] [datetime] NOT NULL,
[LAST_EDIT_TIMESTAMP] [datetime] NOT NULL,
[OPENING_BALANCE] [decimal](18, 2) NOT NULL DEFAULT ((0)),
[OPENING_BALANCE_TYPE] [nvarchar](50) NULL,
CONSTRAINT [PK_dbo.Account]
PRIMARY KEY CLUSTERED ([ID] ASC)
) ON [PRIMARY] TEXTIMAGE_ON [PRIMARY]
CREATE TABLE [dbo].[Voucher]
(
[ID] [int] IDENTITY(1,1) NOT NULL,
[VOUCHERTYPE] [nvarchar](50) NOT NULL,
[VOUCHERNO] [int] NOT NULL,
[DATE] [datetime] NOT NULL,
[AMOUNT] [decimal](18, 2) NOT NULL,
[DRPARTY] [int] NOT NULL,
[CRPARTY] [int] NOT NULL,
[DETAILS] [nvarchar](50) NOT NULL,
[ORIGIN] [nvarchar](50) NULL,
[ORIGINID] [int] NOT NULL,
[ORIGINDETAILS] [nvarchar](max) NULL,
[CREATE_TIMESTAMP] [datetime] NOT NULL DEFAULT ('1900-01-01T00:00:00.000'),
[LAST_EDIT_TIMESTAMP] [datetime] NOT NULL DEFAULT ('1900-01-01T00:00:00.000'),
[TRANSACTION_TYPE] [nvarchar](50) NULL,
CONSTRAINT [PK_dbo.Voucher]
PRIMARY KEY CLUSTERED ([ID] ASC)
) ON [PRIMARY] TEXTIMAGE_ON [PRIMARY]

This is the error I am getting when creating FK relationship via Microsoft SQL Server Management Studio. Both tables are empty.
'Account' table saved successfully
'Voucher' table - Unable to create relationship 'FK_Voucher_Account1'. The ALTER TABLE statement conflicted with the FOREIGN KEY constraint "FK_Voucher_Account1". The conflict occurred in database "SKUMAR", table "dbo.Account", column 'ID'
I want to create a relation between Account.ID -> Voucher.DRPARTY and Account.ID -> Voucher.CRPARTY but I am unable to create second FK relationship.
May I know how to solve this?
There is a possibility of conflicted foreign key error because of data mismatch between Voucher(CRPARTY) column and Account(Id) column. Rows available in CRPARTY table must be in Account table.
Verify using below query.
SELECT * FROM Voucher WHERE CRPARTY NOT IN (SELECT Id FROM Account);
I was able to create 2 FKs to 1 PK. http://rextester.com/WMAT80057
You can delete the FK relationships between your tables and use this script to create them. Hopefully, your tables do not have non matching data.
ALTER TABLE [dbo]. [Voucher] WITH CHECK ADD CONSTRAINT [FK_ACCOUNT_ID_VOUCHER_DRPARTY] FOREIGN KEY ([DRPARTY]) REFERENCES [dbo]. [Account]([ID])
GO
ALTER TABLE [dbo]. [Voucher] CHECK CONSTRAINT [FK_ACCOUNT_ID_VOUCHER_DRPARTY]
GO
ALTER TABLE [dbo]. [Voucher] WITH CHECK ADD CONSTRAINT [FK_ACCOUNT_ID_VOUCHER_CRPARTY] FOREIGN KEY ([CRPARTY]) REFERENCES [dbo]. [Account]([ID])
GO
ALTER TABLE [dbo]. [Voucher] CHECK CONSTRAINT [FK_ACCOUNT_ID_VOUCHER_CRPARTY]

From my original database, I made changes to some tables with columns in the table, I want to merge them into a single database. New database just add some table and old table add some columns.
How to merge multiple database into one database?
SQL example:
CREATE TABLE [dbo].[Item]
(
[ItemID] [nchar](10) NOT NULL,
[Money] [bigint] NOT NULL,
[ItemName] [bigint] NOT NULL,
[MoneyType] [bigint] NOT NULL,
CONSTRAINT [PK_Item]
PRIMARY KEY CLUSTERED ([ItemID] ASC) ON [PRIMARY]
) ON [PRIMARY]
GO
CREATE TABLE [dbo].[Account]
(
[Index] [int] IDENTITY(1,1) NOT NULL,
[AccountID] [nchar](10) NOT NULL,
[AccountName] [int] NOT NULL,
[ItemList] [int] NOT NULL,
) ON [PRIMARY]
GO
CREATE TABLE [dbo].[Money]
(
[AccountID] [nchar](10) NOT NULL,
[Money] [bigint] NOT NULL,
[MoneyType] [bigint] NOT NULL,
CONSTRAINT [PK_Money]
PRIMARY KEY CLUSTERED ([AccountID] ASC) ON [PRIMARY]
) ON [PRIMARY]
GO
-> Nick.McDermaid: use the schema compare tool in Visual Studio (various free editions) which will create a change script!
This will combine them onto DBCombined.Account if the Account table does NOT exist yet: the SELECT INTO code creates the target table. You would then need to add any indexes from the original tables. Also, "SELECT *" should really be broken out, listing each field, because if you have an ID field it will contain duplicates. Better to leave ID off during the insert and then go back and add an identity column.
USE DBCombined
GO
SELECT *
INTO Account
FROM (
SELECT *
FROM DB1.dbo.Account
UNION ALL
SELECT *
FROM DB2.dbo.Account
) Acct
I am using MS Access and having troubles writing a query(s) to get my end result. Maybe someone can lend a hand.
I have Projects, Tasks and SubTasks tables. Each table has a related table for "Assignees". meaning a project could be assigned to an employee but the child tasks could be assigned to a different employee and still further the subtasks could then be assigned to other employees.
Now, when displaying this on screen, and I query for an employee that has been assigned to any project/Task/Subtask. I need that data to display but not other data. So for instance if the employee I query for only has been assigned to a task, then that project and task should display, but no additional projects/tasks/ and no subtasks. Likewise, if I query for an employee that only has been assigned to a subtask, then I only want to see the associated project and task. I think I can complete this with a series of queries...i think... but is there a slick method I can use to create this data.
Simply a select query with a series of joins could possibly work, but it doesnt because when an employee has been assigned to a subtask only and not to a project or task.
Thanks for any assistance!

With regards to queries I have tried...alot. I was implementing a scenario where I ended up with about a half dozen different queries all culminating into one (some of the queries where built with code to allow filtering) However the last one tried was:
SELECT ProjectID, ProjectName, EmployeeID, ProjectTaskID, EmployeeID, Association, ProjectSubTaskID, EmployeeID
FROM (qrTest3_Project LEFT JOIN qrTest2_Task ON qrTest3_Project.ProjectID = qrTest2_Task.ProjectID) LEFT JOIN qrtest1_SubTask ON qrTest2_Task.ProjectTaskID = qrtest1_SubTask.Association
WHERE (((qrTest3_Project.EmployeeID)=8)) OR (((qrTest2_Task.EmployeeID)=8)) OR (((qrtest1_SubTask.EmployeeID)=8));
the above query included other queries that simply joined each project/task/subtask to their respective assignee table. I can post those as well if needed.
I hope that provides the additional information you need? If not, happy to provide more.
Thanks!
I think I may have figured it out..as I sort of suspected, I was making it a bit more difficult then it needed to be. Simply joins really with criteria gives me the data I need and can work with.
SELECT PM_ProjectAssignee.ProjectID, PM_ProjectTasks.ProjectTaskID, PM_ProjectSubTasks.ProjectSubTaskID
FROM (((PM_ProjectAssignee
LEFT JOIN PM_ProjectTasks
ON PM_ProjectAssignee.ProjectID = PM_ProjectTasks.ProjectID)
LEFT JOIN PM_ProjectSubTasks
ON PM_ProjectTasks.ProjectTaskID = PM_ProjectSubTasks.ProjectTaskID)
LEFT JOIN PM_TaskAssignee
ON PM_ProjectTasks.ProjectTaskID = PM_TaskAssignee.ProjectTaskID)
LEFT JOIN PM_SubTaskAssignee
ON PM_ProjectSubTasks.ProjectSubTaskID = PM_SubTaskAssignee.ProjectSubTaskID
WHERE (((PM_ProjectAssignee.EmployeeID)=14))
OR (((PM_TaskAssignee.EmployeeID)=14))
OR (((PM_SubTaskAssignee.EmployeeID)=14))
GROUP BY PM_ProjectAssignee.ProjectID, PM_ProjectTasks.ProjectTaskID, PM_ProjectSubTasks.ProjectSubTaskID;

How can I INSERT data into two tables simultaneously in SQL Server?
Doing a project for school so any help would be great thank you!
I have two tables - how do I insert into two tables? So both tables are linked.
First table is called Customer with primary key called CID that auto increments
CREATE TABLE [dbo].[Customer](
[CID] [int] IDENTITY(1,1) NOT NULL,
[LastName] [varchar](255) NOT NULL,
[FirstName] [varchar](255) NOT NULL,
[MiddleName] [varchar](255) NULL,
[EmailAddress] [varchar](255) NOT NULL,
[PhoneNumber] [varchar](12) NOT NULL
CONSTRAINT [PK__CInforma__C1F8DC5968DD69DC] PRIMARY KEY CLUSTERED
(
And a second table called Employment that has a foreign key linked to the parent table
CREATE TABLE [dbo].[Employment](
[EID] [int] IDENTITY(1,1) NOT NULL,
[CID] [int] NOT NULL,
[Employer] [varchar](255) NOT NULL,
[Occupation] [varchar](255) NOT NULL,
[Income] [varchar](25) NOT NULL,
[WPhone] [varchar](12) NOT NULL,
CONSTRAINT [PK__Employme__C190170BC7827524] PRIMARY KEY CLUSTERED
(
You need to do something like this:
DECLARE #NewID INT
INSERT INTO Customer(LastName,FirstName,......) VALUES(Value1, Value2, .....)
SELECT #NewID = SCOPE_IDENTITY()
INSERT INTO Employment(CID,Employer,.....) VALUES(#NewID, ValueA,..........)
SCOPE_IDENTITY: Returns the last identity value inserted into an identity column in the same scope. A scope is a module: a stored procedure, trigger, function, or batch. Therefore, two statements are in the same scope if they are in the same stored procedure, function, or batch.
I am working on a project where I need to extract the data from excel sheet to SQL Server
, well that bit have done successfully. Now my problem is that for a particular column
called product size, I want to update current table based on product size in other table, I am really very confused , please help me out
Please find the table structure
CREATE TABLE [dbo].[T_Product](
[ProductID] [int] IDENTITY(1,1) NOT NULL,
[PartNo] [nvarchar](255) NULL,
[CategoryID] [int] NULL,
[MaterialID] [float] NULL,
[WireformID] [float] NULL,
[ProductName] [nvarchar](50) NULL,
[ProductSize] [nvarchar](50) NULL,
[ProductLength] [varchar](20) NULL,
[ProductActive] [bit] NULL,
[ProductImage] [varchar](60) NULL
) ON [PRIMARY]
CREATE TABLE [dbo].[T_ProductSize](
[Code] [int] IDENTITY(1,1) NOT NULL,
[ProductSize] [nvarchar](50) NULL,
[Length] [nchar](20) NULL
) ON [PRIMARY]
GO
OK, so ignore the previous answer, I got the wrong end of the stick!!
You want something like this I think:
UPDATE T_Product
SET [ProductLength] = ps.[Length]
FROM T_Product p
INNER JOIN T_ProductSize ps
ON p.[ProductSize] = ps.[ProductSize]
That will take the Length value from T_ProductSize and place it in T_Product.ProductLength based on the value of T_Product.ProductSize
You mention a foreign key but you haven't included a definition for it. Is it between the two tables in your example? If so, which columns make the key? Is product size the key? If so, then your question doesn't make a lot of sense as the value will be the same in both tables.
Is it possible that you mean the product size is to be stored in a separate table and not in the T_Product table? In that case then instead of ProductSize in T_Product you will want the code from the T_ProductSize table (can I also suggest that instead of 'code' you call it 'ProductSizeCode' or better yet 'ProductSizeId' or similar? having columns simply called code can be very confusing as you have no simple way of know what table that value is in). Also, you should always create a primary key on each table: You cannot have a foreign key without one. They don't have to be clustered, that will depend upon hwo your search the table, but I am using a clustered PK for this example. That would give you something like this:
CREATE TABLE [dbo].[T_Product](
[ProductID] [int] IDENTITY(1,1) NOT NULL,
[PartNo] [nvarchar](255) NULL,
[CategoryID] [int] NULL,
[MaterialID] [float] NULL,
[WireformID] [float] NULL,
[ProductName] [nvarchar](50) NULL,
[ProductSizeId] [int] NOT NULL,
[ProductLength] [varchar](20) NULL,
[ProductActive] [bit] NULL,
[ProductImage] [varchar](60) NULL
CONSTRAINT [PK_T_Product] PRIMARY KEY CLUSTERED
(
[ProductID] ASC
) ON [PRIMARY]
) ON [PRIMARY]
GO
CREATE TABLE [dbo].[T_ProductSize](
[ProductSizeId] [int] IDENTITY(1,1) NOT NULL,
[ProductSize] [nvarchar](50) NULL,
[Length] [nchar](20) NULL
CONSTRAINT [PK_T_ProductSize] PRIMARY KEY CLUSTERED
(
[ProductSizeId] ASC
) ON [PRIMARY]
) ON [PRIMARY]
GO
--Now add your foreign key to T_Product.
ALTER TABLE [T_Product] WITH NOCHECK ADD CONSTRAINT [FK_Product_ProductSize] FOREIGN KEY([ProductSizeId])
REFERENCES [T_ProductSize] ([ProductSizeId])
GO
ALTER TABLE [T_Product] CHECK CONSTRAINT [FK_Product_ProductSize]
GO
Now, to retrieve your product along with the product size use something like this:
SELECT p.[ProductID], p.[PartNo], p.[CategoryID], p.[MaterialID], p.[WireformID], p.[ProductName],
ps.[ProductSize], ps.[Length], p.[ProductLength], p.[ProductActive], p.[ProductImage]
FROM [T_Product] p
INNER JOIN [T_ProductSize] ps
ON ps.[ProductSizeId] = p.[ProductSizeId]
If I have understood you correctly, then this is what I think you're after. If not, then have another go at explaining what it is you need and I'll try again.
Try this...
UPDATE t2
SET t2.ProductLength = t1.Length
FROM dbo.T_ProductSize t1
INNER JOIN dbo.T_Product t2 ON t1.ProductSize = t2.ProductSize
