Backup a single table with data in SQL Server [duplicate] - sql

I want to get a backup of a single table with its data from a database in SQL Server using a script.
How can I do that?

SELECT * INTO mytable_backup FROM mytable
This makes a copy of table mytable, and every row in it, called mytable_backup. It will not copy any indices, constraints, etc., just the structure and data.
Note that this will not work if you have an existing table named mytable_backup, so if you want to use this code regularly (for example, to backup daily or monthly), you'll need to run drop mytable_backup first.

You can use the "Generate script for database objects" feature on SSMS.
Right click on the target database
Select Tasks > Generate Scripts
Choose desired table or specific object
Hit the Advanced button
Under General, choose value on the Types of data to script. You can select Data only, Schema only, and Schema and data. Schema and data includes both table creation and actual data on the generated script.
Click Next until wizard is done

There are many ways you can take back of table.
BCP (BULK COPY PROGRAM)
Generate Table Script with data
Make a copy of table using SELECT INTO, example here
SAVE Table Data Directly in a Flat file
Export Data using SSIS to any destination

You can create table script along with its data using following steps:
Right click on the database.
Select Tasks > Generate scripts ...
Click next.
Click next.
In Table/View Options, set Script Data to True; then click next.
Select the Tables checkbox and click next.
Select your table name and click next.
Click next until the wizard is done.
For more information, see Eric Johnson's blog.

Put the table in its own filegroup. You can then use regular SQL Server built in backup to backup the filegroup in which in effect backs up the table.
To backup a filegroup see:
https://learn.microsoft.com/en-us/sql/relational-databases/backup-restore/back-up-files-and-filegroups-sql-server
To create a table on a non-default filegroup (its easy) see:
Create a table on a filegroup other than the default

Another approach you can take if you need to back up a single table out of multiple tables in a database is:
Generate script of specific table(s) from a database (Right-click database, click Task > Generate Scripts...
Run the script in the query editor. You must change/add the first line (USE DatabaseName) in the script to a new database, to avoid getting the "Database already exists" error.
Right-click on the newly created database, and click on Task > Back Up...
The backup will contain the selected table(s) from the original database.

To get a copy in a file on the local file-system, this rickety utility from the Windows start button menu worked:
"C:\Program Files (x86)\Microsoft SQL Server\110\DTS\Binn\DTSWizard.exe"

How do I transfer a schema and all of its tables to a new database?

I have database a with schema foo which contains 20 tables. I want to move all of the contents of schema foo into database b without overriding the current content in database b.
Is there also a way to do it in pgadmin?
I found this link and perhaps it will be quite similar. But this particular link is for transferring a table.
Copy a table from one database to another in Postgres
You can script the first database with all its data once scripted you can run the th script within the other database it should work as long as you dont have tables in the second database with the same name
so in pg admin follow these steps to script the
-Right click on the database and click Backup.
-Selece a filepath and filename on where you want to save your script
-Select Plain as the format in the format dropdown.
-Go to Options and check "schema and data" in tab # 1.
-Then click on Backup.
-Then click Done.
-Then right click on your 2nd database and create a new query.
-Find where you saved the script and copy the script to the query
-run the query and should be all good
if you are unsure about this just create 2 practice databases and practice on those before you do it on the main one

How can I carry a database created in dbDesigner to SQL Server

I created a small database in dbDesigner which includes 4 tables, and I want to add these tables with their relationships to a database on a SQL Server. How can I do this?
Best practice for this that I am aware of, is using Management Studio's functionality for this.
The following steps will produce a file containing an SQL script you can run on any server you want in order to import the schema (with or without the data).
Right click on you database.
Select Tasks > Generate scripts
Click Next
Choose Script entire database and all database objects
Select Save to file and Single file
If you want to export data as well, click on Advanced and change Types of data to script to Schema and data (default is schema only)
Click Next ... Next.
Run the generated file on the server you want to import the schema to.

Transfer data from one database to another database

How to fetch the data from one database and insert in to another database table? I can't to do this. Please help me in transferring data from one to another.
There are several ways to do this, below are two options:
Option 1
- Right click on the database you want to copy
Choose 'Tasks' > 'Generate scripts'
'Select specific database objects'
Check 'Tables'
Mark 'Save to new query window'
Click 'Advanced'
Set 'Types of data to script' to 'Schema and data'
Next, Next
You can now run the generated query on the new database.
Option 2
Right click on the database you want to copy
'Tasks' > 'Export Data'
Next, Next
Choose the database to copy the tables to
Mark 'Copy data from one or more tables or views'
Choose the tables you want to copy
Finish
Example for insert into values in One database table into another database table running on the same SQL Server
insert into dbo.onedatabase.FolderStatus
(
[FolderStatusId],
[code],
[title],
[last_modified]
)
select [FolderStatusId], [code], [title], [last_modified]
from dbo.Twodatabase.f_file_stat
For those on Azure, follow these modified instructions from Virus:
Open SSMS.
Right-click the Database you wish to copy data from.
Select Generate Scripts >> Select Specific Database Objects >> Choose the tables/object you wish to transfer.
strong text
In the "Save to file" pane, click Advanced
Set "Types of data to script" to Schema and data
Set "Script DROP and CREATE" to Script DROP and CREATE
Under "Table/View Options" set relevant items to TRUE. Though I recommend setting all to TRUE just in case. You can always modify the script after it generates.
Set filepath >> Next >> Next
Open newly created SQL file. Remove "Use" from top of file.
Open new query window on destination database, paste script contents (without using) and execute.
if both databases are on same server and you want to transfer entire table (make copy of it) then use simple select into statement ...
select * into anotherDatabase..copyOfTable from oneDatabase..tableName
You can then write cursor top of sysobjects and copy entire set of tables that way.
If you want more complex data extraction & transformation, then use SSIS and build appropriate ETL in it.
You can use visual studio 2015. Go to Tools => SQL server => New Data comparison
Select source and target Database.
You can backup and restore the database using Management Studio.
Again from Management Studio you can use "copy database".
you can even do it manually if there is a reason to do so. I mean manually create the target db and manually copying data by sql statements...
can you clarify why you ask this? Is it that you dont have expierience in doing it or something else?
There are multiple options and depend on your needs.
See the following links:
Copying Data Between Servers
Copy tables from one database to another in SQL Server.
These solutions are working in case when target database is blank.
In case when both databases already have some data you need something more complicated http://byalexblog.net/merge-sql-databases
This can be achieved by a T-SQL statement, if you are aware that FROM clause can specify database for table name.
insert into database1..MyTable
select from database2..MyTable
Here is how Microsoft explains the syntax:
https://learn.microsoft.com/en-us/sql/t-sql/queries/from-transact-sql?view=sql-server-ver15
If the table or view exists in another database on the same instance of SQL Server, use a fully qualified name in the form database.schema.object_name.
schema_name can be omitted, like above, which means the default schema of the current user. By default, it's dbo.
Add any filtering to columns/rows if you want to. Be sure to create any new table before moving data.
Doing this programmatically between two different databases could involve a scheduled job using a linked server. But linked servers require DBA-level knowledge to set up. If you can't use a linked server, just write a program that 1. Reads a row from the source table and 2. Inserts it into the target table. The programmer just needs to use a connection string that has INSERT privileges into the target database table. I have solved this problems using both approaches.

Generate script in SQL Server Management Studio

If I have a table with data in a database in SQL Server, how can I generate a script that will create the table and add the data too?
If I right click on the table then select Script Table As > Create to > File, that generates a script to just create the table without the data. What I need is a script that creates the table and adds the data that is already existing in the table or 2 separate scripts, one that creates the table and one that adds the data.
Here what you have to do:
right click the database (not the table) and select tasks --> generate scripts
Next --> select the requested table/tables (from select specific database objects)
next --> click advanced --> types of data to script = schema and data
next and finish
Use SSMS scripting feature (Rightclick on database->Tasks->Generate Scripts)
or
use SSMS Tools Pack
Here You can see step by step process of Generate script in SQL Server Management Studio :
Step 1: Right Click on Your Database --> Select Task-->Generate Script..
Step 2: Select Next in Script Wizard
Step 3: Select Script Entire Database
Step 4:Choose Your File Name
and Finish
Now you can use your script file.
Be aware that generating scripts (schema and data) does not export duplicate ROWS
Do a test (only need 2 columns and half a dozen rows) - I wondered what was happening - in the end it turned out to be a good thing in this instance

How to backup Sql Server to sql file?

In "Back UP" I only get a bak file, but I would like to create .sql file
Use SQL Server's Generate Scripts commend
right click on the database; Tasks -> Generate Scripts
select your tables, click Next
click the Advanced button
find Types of data to script - choose Schema and Data.
you can then choose to save to file, or put in new query window.
results in CREATE and INSERT statements for all table data selected in bullet 2.
This is a possible duplicate of: SQL script to get table content as "SELECT * FROM tblname"
To do a full database backup to File/Query you can use the 'Generate Scripts...' option on the Database.
Open SQL Server Management studio, right click on the database and choose 'Tasks->Generate Scripts...'
Then use the wizard to backup the database. You can script the whole database or parts of it. Two important options: In the 'Advanced' section, you will probably want to ensure 'Type of backup = 'Schema and Data' and the 'Script Statistics' is on.
This will produce a *.sql file that you can use as a backup that includes the schema and table data.
Ok, I read through most of these, but I had no "advanced button". But, there is still a way to do it, it's just a little hard to find, so here you go:
You can generate a script from a database, see http://msdn.microsoft.com/en-us/library/ms178078.aspx
If you want to create a script of your database you right-click on the databases and Generate Scripts (it's in different sub-menus depending on what version of SQL and Enterprise Manager / SQL Server Management studio you're using).
That will, however, only get you the database objects. It will not generate scripts for data. Backing up a database will give you all of the database objects as well as the data, depending on what recovery model your database is set to.
This fellow may have achieved what you are trying to do by creating the backup, and then restoring it and giving it a new name.
This approach copies the data along with all of the database objects.
If you want a file with insert statements for your data have a look here:
This procedure generates INSERT statements using existing data from the given tables and views. Later, you can use these INSERT statements to generate the data. It's very useful when you have to ship or package a database application. This procedure also comes in handy when you have to send sample data to your vendor or technical support provider for troubleshooting purposes.
