Hello I' new to IBM DB2 Express-C
I have a exported a database to .sql file (Original database stored in SQLite3 - used SQLite SQLite Manager for exporting the the database to a .sql file)
Can anyone please tell a way to import a this .sql file into DB2. Thank you
If you want to execute a set of sentences in a file in DB2, you issue in the command line (db2clp):
db2 -tvf <filename>
For exmpale, for your file
db2 -tvf myfile.sql
However, the content of that file could not be compliant with DB2, and you have to modify it, in order to run correctly in DB2.
Basic Create tables, and DML (insert, delete, update) are SQL 92 standard accross many database. But if you have create bufferpool, tablespaces, and other kind of objects, you have tomodify the file a lot.

I need to export a 50gb file with inserts to a table in postgreSQL to be able to count the time it takes to perform the inserts, but I can't find any way to load that file, can someone help me?
If the file have you have contains syntactically valid SQL (like INSERT statements), this is very straightforward using the command line psql client that comes with a Postgres installation:
psql DATABASE_NAME < FILE_NAME.sql
You may also want to replace DATABASE_NAME with a connection string like postgres://user:pass#localhost/database_name.
This causes your shell to read the given file and pass it off to psql's stdin, which will cause it to execute commands against the database it's connected to.
I want to load chinook database in SQLite but I have no idea how can I do that.
First, I used this command but it just made a file without anything in it:
sqlite3 chinook.db
I also downloaded this archive that contains chinook database but I couldn't find chinook.db file to open it with this command:
.open chinook.db
If you have a copy of the chinook database then just use the restore database feature.
cd /home/sqlite
mv sample.db sample.db.old
sqlite3 sample.db < sample.bak

We should script the database before using it. Here is the link that discussed the whole procedure.
Is there a command line interface where I can run a script that says, for example:
Connect to server a
Run query 1
Connect to server b
Run query 2
Run query 3
I tried searching online but couldnt find anything built into SQL Server Management Studio.
Thanks!
The sqlcmd Utility
http://msdn.microsoft.com/en-us/library/ms162773.aspx
It usually ships with the SQL Server installer and is located in the following directory by default:
C:\Program Files\Microsoft SQL Server\100\Tools\Binn\SQLCMD.EXE
If you want to export in/out there is a command-line utility called BCP that will let you execute these types of processes.
bcp Utility
The bcp utility bulk copies data between an instance of Microsoft SQL
Server and a data file in a user-specified format. The bcp utility can
be used to import large numbers of new rows into SQL Server tables or
to export data out of tables into data files. Except when used with
the queryout option, the utility requires no knowledge of
Transact-SQL. To import data into a table, you must either use a
format file created for that table or understand the structure of the
table and the types of data that are valid for its columns.
I have a .sql file and I am trying to import it into SQL Server 2008. What is the proper way to do this?
If your file is a large file, 50MB+, then I recommend you use sqlcmd, the command line utility that comes bundled with SQL Server. It is easy to use and it handles large files well. I tried it yesterday with a 22GB file using the following command:
sqlcmd -S SERVERNAME\INSTANCE_NAME -i C:\path\mysqlfile.sql -o C:\path\output_file.txt
The command above assumes that your server name is SERVERNAME, that you SQL Server installation uses the instance name INSTANCE_NAME, and that windows auth is the default auth method. After execution output.txt will contain something like the following:
...
(1 rows affected)
Processed 100 total records
(1 rows affected)
Processed 200 total records
(1 rows affected)
Processed 300 total records
...
use readfileonline.com if you need to see the contents of huge files.

If you are talking about an actual database (an mdf file) you would Attach it
.sql files are typically run using SQL Server Management Studio. They are basically saved SQL statements, so could be anything. You don't "import" them. More precisely, you "execute" them. Even though the script may indeed insert data.
Also, to expand on Jamie F's answer, don't run a SQL file against your database unless you know what it is doing. SQL scripts can be as dangerous as unchecked exe's
Start SQL Server Management Studio
Connect to your database
File > Open > File and pick your file
Execute it
Try this process -
Open the Query Analyzer
Start --> Programs --> MS SQL Server --> Query Analyzer
Once opened, connect to the database that you are wish running the script on.
Next, open the SQL file using File --> Open option. Select .sql file.
Once it is open, you can execute the file by pressing F5.
In order to import your .sql try the following steps
Start SQL Server Management Studio
Connect to your Database
Open the Query Editor
Drag and Drop your .sql File into the editor
Execute the import
A .sql file is a set of commands that can be executed against the SQL server.
Sometimes the .sql file will specify the database, other times you may need to specify this.
You should talk to your DBA or whoever is responsible for maintaining your databases. They will probably want to give the file a quick look. .sql files can do a lot of harm, even inadvertantly.

Get the names of the server and database in SSMS:
Run the following command in PowerShell or CMD:
sqlcmd -S "[SERVER NAME]" -d [DATABASE NAME] -i .\[SCRIPT].sql
Here is a screenshot of what it might look like:
There is no such thing as importing in MS SQL. I understand what you mean. It is so simple. Whenever you get/have a something.SQL file, you should just double click and it will directly open in your MS SQL Studio.
Hai i am a beginner of Database,
i have a .sql file which contains some tables of data, i want to know how to import them and how to view the list of tables.
presently im using the following:-
software or editor : navicat lite
server : localhost.
databse file format: .sql
Maybe you can try to execute the script in sql server, then type
select * from [database_name].information_schema.tables
to view tables and relevant information.
Remember that a sql file is not really a database, it is a script. You can run the script from any tool, but I'd use command line. This is navicat connected to mysql?
mysql -u username -p databasename < script.sql
password: **
And then the results can be seen using navicat or any other tool
If the .sql file has statements such as "CREATE TABLE..." and then later on "INSERT INTO..." then the script is possibly creating the tables and inserting the data.
To allow that to happen, the tables need to not exist in the database. You can then run the script and it will create the tables and fill in the data.
If the tables do exist, you can always either delete them, or change the CREATE to an ALTER and the script should then run.
Hope that helps.
