I want to copy all data from one database to another which has the same structure. The databases reside on the same machine & on same sql server.
I have googled a bit & have found solutions like this
INSERT states (statecode, statename)
SELECT statecode, statename
FROM server1.database1.dbo.states
But the problem is they are copying table by table & I have like more then 100 tables. I was thinking that is there a way to copy all of the data at once.
Views & stored procedures all should be copied.
Or should I be looking in some other direction to achieve this ...?
If this is a one-time need, use the (Database) > Tasks > Generate Scripts menu option in SQL Server Management Studio.
Some options:
Use the DB back up and restore tools to just move a big backup file. This is the simplest option.
Slave the 2nd instance off of the 1st. It'll keep it up to date, but can be a pain.
Use import export wizard to transfer the data from one DB to another DB and use Generate script for the Transfer the Procedure and views.
Check out tools like Red-Gate SQL Compare (for structural comparison) and SQL Data Compare (for data content compare). With Data Compare, you can also easily update one database from another (or a database backup, even).
They're not free - but if you have to do this several times over and over, just the time (not to speak of the hassle) you save yourself will easily outweigh the cost of purchasing these tools. Excellent stuff - highly recommended!

I have a one problem. I have a database(MSSQL) on some server. I need copy this DB on my local DB. But! This DB is huge 7gb. I don't need data from this DB. I need just copy structure of this DB (What I mean about structure - all DB, all tables, connections, etc. (!!!But I don't need a data from this tables)). How I understand it - It will clean DB with the same structure.
I have no idea how implement it. I read what I can do it using PowerShell, Git and SQL manager. But i didn't find example. Could you tell me something about it?
Right click on your Database => Tasks => Generate Scripts
Screenshots shows this on a System Database. Don't do this on system databases.
Select the Tables / Views / Stored Procedures you want.
Change the scripting options depending on your preferences/requirements.
Generate the script
If you use MS SQL Server Management Studio, you can right-click on the tables you want to have in your other db -> Generate Script for -> Create -> and then choose one opion.
Only drawback is, that you have to do that for every table individually.
I am in need of suggestion to move data from a particular table in one azure sql database to the other azure sql database which has the same table structure without using elastic query
Using SQL Server Management Studio to connect to SQL azure database, right click the source database and select generate scripts.
During the wizard, after have select the tables that you want to output to a query window, then click advanced. About half way down the properties window there is an option for "type of data to script". Select that and change it to "data only", then finish the wizard.
The heck the script, rearrange the inserts for constraints, and change the using at the top to run it against my target DB.
Then right click on the target database and select new query, copy the script into it, and run it.
This will migrate the data.
Please consider using the "Transfer SQL Server Objects task" in SSIS. You can learn all the advantages it provides on this article.
You can use PowerShell to query each database and move data between them as needed. Here's an example article on how to get this done.
Using PowerShell when working with Azure has a number of other benefits in what you can do and can control as well. It's a good choice to spend time learning.
In the source database I created SPs to select the data from the tables.
In the target database I created table types (which would be available in programmability) for the tables with the same structure as in the source.
I used Azure function to move the data into table type from source.
In the target database I created SPs to insert data into the tables from their respective table types.
After ensuring the transfer of data, I would be deleting those records moved to the target in the source database and for this I created SPs.
I have developed a SQL Express database. I need to backup all but one table in that database in an automated way. I was thinking i could write a SQL script to do this, trigger it using sqlcmd from a batch file but not sure how to write that SQL script.
I was also thinking, if nothing else possible, i could create a second db that has the tables i want to backup then i write a script that copys data 'into' the second db and then do a auto backup of that entire db. This has the disadvantage of having a procrastinated unpacking of that backup when wanting to use it - its not a small install script.
Is this a possibility, is it the only option or is there tools for SQL Express to do this?
There is no option to exclude just one table while backing up .Few things i could think of
1.Right click database ->Tasks ->generate scripts ->exclude the table you want and choose to save the script and run this every time
2.you could also choose Export option,but since you are using SQL Express,you wont have the option to save this package
Keep the large table in a different database and just backup the original database. You can still use the large table even in a different database, i.e.
SELECT *
FROM MyDb.dbo.SomeTable s
JOIN OtherDb.dbo.LargeTable l
ON (expression);
How do I copy data from multiple tables within one database to another database residing on a different server?
Is this possible through a BTEQ Script in Teradata?
If so, provide a sample.
If not, are there other options to do this other than using a flat-file?
This is not possible using BTEQ since you have mentioned both the databases are residing in different servers.
There are two solutions for this.
Arcmain - You need to use Arcmain Backup first, which creates files containing data from your tables. Then you need to use Arcmain restore which restores the data from the files
TPT - Teradata Parallel Transporter. This is a very advanced tool. This does not create any files like Arcmain. It directly moves the data between two teradata servers.(Wikipedia)
If I am understanding your question, you want to move a set of tables from one DB to another.
You can use the following syntax in a BTEQ Script to copy the tables and data:
CREATE TABLE <NewDB>.<NewTable> AS <OldDB>.<OldTable> WITH DATA AND STATS;
Or just the table structures:
CREATE TABLE <NewDB>.<NewTable> AS <OldDB>.<OldTable> WITH NO DATA AND NO STATS;
If you get real savvy you can create a BTEQ script that dynamically builds the above statement in a SELECT statement, exports the results, then in turn runs the newly exported file all within a single BTEQ script.
There are a bunch of other options that you can do with CREATE TABLE <...> AS <...>;. You would be best served reviewing the Teradata Manuals for more details.
There are a few more options which will allow you to copy from one table to another.
Possibly the simplest way would be to write a smallish program which uses one of their communication layers (ODBC, .NET Data Provider, JDBC, cli, etc.) and use that to take a select statement and an insert statement. This would require some work, but it would have less overhead than trying to learn how to write TPT scripts. You would not need any 'DBA' permissions to write your own.
Teradata also sells other applications which hides the complexity of some of the tools. Teradata Data Mover handles provides an abstraction layer between tools like arcmain and tpt. Access to this tool is most likely restricted to DBA types.
If you want to move data from one server to another server then
We can do this with the flat file.
First we have fetch data from source table to flat file through any utility such as bteq or fastexport.
then we can load this data into target table with the help of mload,fastload or bteq scripts.
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.
