I want to extract only table structure from a SQL Server database. But if I extract normally using export wizard only single file is created but I want to create separate files for separate tables.
Could anybody tell me how to do this in SQL Server ?
Go to Object Explorer, pick Generate Scripts:
Then select what objects to script out, and on the second page of the wizard, select Single File Per Object:
Run the wizard and you have your one file per object as you need it.

I have two different databases in two different SQL Servers. The databases are identical in schema but contain different data in one of the tables.
I want to copy all the data from one table in one database to the same table in the other database so that I can get rid of the database from which I am copying the data.
The data is too large so I cannot create data scripts and run it onto other database.
How can I achieve this?
There are many ways like ssis transfer,select * into ,but i prefer below way if you are just transferring data
create a linked server on source server for destination server,then you could refer destination server with four part name
Assuming linked server of source is A and destination server is B,data moving is as simple as
insert into B.databasename.Schema.Table
select * from table---this is in source server and db
if data is huge and you may worry about time outs,you can write a simple script which can do in batches like
While (1=1)
begin
insert into B.databasename.Schema.Table
select top 10000* from table---this is in source server and db
if (##rowcount=0)
break
end
Creating linked server ,you can follow this
You have the following options available to you. Not all of these will work, depending on your exact requirements and the networking arrangements between the servers.
SQL Server Management Studio - Import & Export Wizard: this is accessed from the right-click menu for a database > Tasks > Import Data (or Export Data).
SQL query using a Linked Server: a Linked Server configured between the two servers allows you to reference databases on one from the other, in much the same way as if they were on the same server. Any valid SQL query approach for transferring data between two tables within one database will then work, provided you fully-qualify the table names as Server.Database.Schema.Table.
SSIS: create an SSIS package with both servers as connections, and a simple workflow to move the data from one to the other. There is plenty of information available online on how to use SSIS.
Export to flat-file format then import: this could be done using the Import/Export Wizard above or SSIS, but instead of piping the data directly between the two servers, you would output the data from the source table into a suitable flat-file format on the filesystem. CSV is the most commonly used format for this. This file can then be moved to the destination server using any file transfer approach (compressed e.g. to a Zip file if desired), and imported into the destination table.
Database backup and restore: Similar to (4), but instead of using a flat file, you could create a backup of the source database via Tasks > Back Up... You then move that backup as a file (just like the CSV approach), and restore it onto the destination server. Now you have two databases on the destination server, and can move data from one to the other locally.
I hope, this query helps you!!!
INSERT INTO [dbo].[tablename] (Column1, Column2,Column3)
(select Column1, Column2,Column3, from [Database1].[dbo].[tablename]
Thanks!!!
I am trying to import a .csv files into my sql Database that has been created on the SQL server 2014. The problem is that my csv tables have different names from the tables that I have create in my own Database. I cannot change the names on the csv files or the names on my database. They have to stay as they are. Can import the csv files into each table on my database without having an error? please help me out, i'm confused.
Use the import export wizard that is packaged with SQL Server, you can set the data source to a flat file such as CSV. It has a built in mapping option as below
I assume you are using import wizard, but once you pick data source and data destination, go to option "edit Mappings", there you can check which columns goes where, just make sure that columns are the same type
Yes, Steps:
Select the database
Right Click and Select the task and click on export
Select the source database and click next and select the CSV database as destination
click next and do the mapping of Source and destination columns
Click next to Finish
Now data will be imported to the database on appropriate columns
I've created the structure of my database first in PhpMyAdmin and exported it to a .sql file.
Now I'm looking everywhere in SQL Server Management Studio where I can import/add the data in a new database.
Does anybody where to look or what to click?
I'm using the 2014 version (CTP2)
If you have a .sql file which contains SQL statements, you can just copy and paste the contents (or open the file in a query window) and run it. This assumes it has all of the create table etc. statements to create the schema/structure and not just insert statements for the data.
Check the top of the file to make sure that it is first selecting the correct database, if not add a USE statement to select the correct database.
You didn't say how big the file was, but if it is quite large and has the insert statements (data as well as schema), then you'll probably want to run by CLI using sqlcmd command. Much faster and SSMS won't freak out.
Another alternative option to running the .sql file/code is to set up a data source for mysql and just use odbc to access the database itself.
Bear in mind that there are real and very annoying differences between mysql and t-sql that can make migration a pain. If you're just creating a few tables, it may not be an issue, but if there are a ton of tables with lots of fields of different data types, you may run into issues.
If you are looking to import table structure, you can copy-paste the content and run inside SSMS in a query window. Beware of syntax differences with MySQL and SQL Server. You will most likely get errors. You need to convert your SQL script from MySQL dialect to SQL Server dialect (or just add them manually if they are not too many). If you set the databases to a SQL standard-compatibility mode at the very beginning, you will have much less trouble.
If you are ONLY looking just to import the data into existing tables inside the SQL Server only, you can do the same (i.e. copy-paste and run in query window). You will have less trouble with that.
Open the server, open "Databases" and right click the database, go to "Tasks" and then Import Data...
I have had the most 'trouble free' success importing to SQL via a flat file method (comma delimited .txt file), the only stipulation when creating a flat file (i.e from Access) make sure the text identifier is set to {none} and not "".
To import the file: in the SQL Server Management Studio right click on Databases and create a new database. Then right click on the new database -> Tasks -> Import Data... The import window opens: in the DATA SOURCE option select Flat File Source and select the .txt file...click NEXT. In the DESTINATION field select SQL Server Native Client 11.0 and go through the import process. This worked very well for me.
I have two tables in database. I want to create a .csv file to maintain all activities done on that two tables. I need help in converting these two tables data into one single .csv file in oracle apex.
Are you just trying to export the data to a CSV?
write an SQL select query to link both the tables together. If you need help with this, let us know
create a Report and enter the SQL in the source
go to Report Attributes, there is an option called Enable CSV Output. Make sure this is set to Yes
Run the page, there should be a hyperlink or button beneath the report which exports the file.
I would like to copy a table from one database to another. I know you can easily do the following if the databases are on the same SQL Server.
SELECT * INTO NewTable FROM existingdb.dbo.existingtable;
Is there any easy way to do this if the databases are on two different SQL Servers, without having to loop through every record in the original table and insert it into the new table?
Also, this needs to be done in code, outside of SQL Server Management Studio.
Yes. add a linked server entry, and use select into using the four part db object naming convention.
Example:
SELECT * INTO targetTable
FROM [sourceserver].[sourcedatabase].[dbo].[sourceTable]
If it’s only copying tables then linked servers will work fine or creating scripts but if secondary table already contains some data then I’d suggest using some third party comparison tool.
I’m using Apex Diff but there are also a lot of other tools out there such as those from Red Gate or Dev Art...
Third party tools are not necessary of course and you can do everything natively it’s just more convenient. Even if you’re on a tight budget you can use these in trial mode to get things done….
Here is a good thread on similar topic with a lot more examples on how to do this in pure sql.
SQL Server(2012) provides another way to generate script for the SQL Server databases with its objects and data. This script can be used to copy the tables’ schema and data from the source database to the destination one in our case.
Using the SQL Server Management Studio, right-click on the source database from the object explorer, then from Tasks choose Generate Scripts.
In the Choose objects window, choose Select Specific Database Objects to specify the tables that you will generate script for, then choose the tables by ticking beside each one of it. Click Next.
In the Set Scripting Options window, specify the path where you will save the generated script file, and click Advanced.
From the appeared Advanced Scripting Options window, specify Schema and Data as Types of Data to Script. You can decide from here if you want to script the indexes and keys in your tables. Click OK.
Getting back to the Advanced Scripting Options window, click Next.
Review the Summary window and click Next.
You can monitor the progress from the Save or Publish Scripts window. If there is no error click Finish and you will find the script file in the specified path.
SQL Scripting method is useful to generate one single script for the tables’ schema and data, including the indexes and keys. But again this method doesn’t generate the tables’ creation script in the correct order if there are relations between the tables.
Microsoft SQL Server Database Publishing Wizard will generate all the necessary insert statements, and optionally schema information as well if you need that:

Generate the scripts?
Generate a script to create the table then generate a script to insert the data.
check-out SP_ Genereate_Inserts for generating the data insert script.
Create the database, with Script Database as... CREATE To
Within SSMS on the source server, use the export wizard with the destination server database as the destination.
Source instance > YourDatabase > Tasks > Export data
Data Soure = SQL Server Native Client
Validate/enter Server & Database
Destination = SQL Server Native Client
Validate/enter Server & Database
Follow through wizard
