I am trying to export a large query from a DB2 database to a text file on my desktop using IBM Data Studio and I can't seem to get anything to work. When I run the query and right click on the results tab->Export->All Results it only gives me the first 500 records. This table is going to be in the range of 15 MM records so I can't just change the display settings to allow it to display that many records. I cannot use the unload utility because it won't let me save the file to my desktop. Any ideas?
Probably, the limit in the SQL Results is activated.
You should click in the upper left triangle in the "SQL results" view, then "Preferences...".
However, this is not a good way to export data, because you should fetch them into Data Studio and then export them via the GUI. It is better to use the "export" command.
IN the IBM Data Studio:
right click the table/view and ---->Data-----> Extract and Browse destination to drop the file.

I need to export SQL Server 2017 database; can anyone please help me where I can find this?
Right click on a database ► Tasks ► Generate Scripts...
Select Script entire database and all database objects. Next like there is no tomorrow.
If you would like to include data as well, on the second step there is Advanced button. Find Types of data to script, then you can include data to schema as well. But there are more efficient ways to copy data exist.
How can I generate large table scripts ( data only) in sql server 2012?

Please suggest.
To do large amounts of just data the bcp Utility may be of a lot of help it can export data very quickly. It is through the cmd prompt but it is very clean and fast
It is a bulk copy.
This is the information from Microsoft

Look into DTS Wizard. It is fast, easy and just right for such one time jobs. You can control where the data goes to, including another SQL Server, Excel, CSV, etc.... And, if needed, move the data in reverse, from your backup medium back into the original database. DTS Wizard...don't go anywhere without it. ;)
Right click your database in the Object Explorer
Choose Tasks
Choose Export Data to bring up the SQL Server Import and Export Wizard and pick your source (DB and table or query) and destination.
I'm trying to load a large file into a SQL Server table. I know that two of the columns are > 50 characters wide so on the 'Advanced' tab in the Import/Export Wizard, I specify the width as 115 and 75 respectively. I then run the rest of the job and get the following error:
Is there another place I need to let the Wizard know about the change in length?
Check your database. There is a chance that the table was created from your previous unsuccessful wizard run. It is recommended to delete the table and wizard should re-run successfully without warnings.
Try letting the import wizard create the new table for you. Then you can use regular SQL to move it to its permanent table.
How to export Oracle DB data using SQL Developer? I need all data, tables, constraints, structure and so on.
In SQL Developer, from the top menu choose Tools > Data Export. This launches the Data Export wizard. It's pretty straightforward from there.
There is a tutorial on the OTN site. Find it here.
In version 3, they changed "export" to "unload". It still functions more or less the same.
If, at some point, you only need to export a single result set, just right click "on the data" (any column of any row) there you will find an export option.
The wizard exports the complete result set regardless of what you selected
To export data you need to right click on your results and select export data, after which you will be asked for a specific file format such as insert, loader, or text etc. After selecting this browse your directory and select the export destination.
Version 3.0.3. It's a fairly large result-set, around 3 million rows.
Martin pretty much has this right.
The TL/DR version is that you need the "SQLScripts" plugin (which is one of the "standard' plugins), and then you can select these menu options: Session > Scripts > Store Result of SQL in File
I'm looking at version 3.4. I don't know when this feature was introduced but you may need to upgrade if you don't have and cannot install the SQLScripts plugin.
Instructions for installing a new plugin can be found at: http://squirrel-sql.sourceforge.net/user-manual/quick_start.html#plugins
But if you're performing a fresh install of Squirrel you can simply select the "SQLScripts" plugin during the installation.
Here's the long version:
Run the query
Connect to the database. Click on the SQL tab. Enter your query. Hit the run button (or Ctrl-Enter).
You should see the first 100 rows or so in the results area in the bottom half of the pane (depending upon how you've configured the Limit Rows option).
Export the full results
Open the Session menu. Select the Scripts item (nearly at the bottom of this long menu). Select Store Result of SQL in File.
This opens a dialog box where you can configure your export. Make sure you check Export the complete result set to get everything.
I haven't tried this with a 3 million row result set, but I have noticed that Squirrel seems to stream the data to disk (rather than reading it all into memory before writing), so I don't see any reason why it wouldn't work with an arbitrarily large file.
Note that you can export directly to a file by using Ctrl-T to invoke the tools popup and selecting sql2file.
I have found a way to do this, there is a nice support for this in Squirrel. Run the SQL select (the 100 row limit will be ignored by the exporter, don't worry). Then, in the main menu, choose Session, Scripts, Store Result of SQL in File. This functionality may not be present by default, it may be present in some standard plugin (but not installed by default). I don't know which plugin though.
I also wanted to export results of SQL query to CSV file using SquirrelSQL. However according to changes file it seems that this functionality is not supported even in SquirrelSql 3.3.0.
So far I was able to export only data shown in 'result table' of SQL query by right click on the table > Export to CSV. The table size is by default 100 rows and so is the CSV export. You may change the table size in Session Properties > SQL > Limit rows. E.g. change the size to 10000 and your export will also contain 10000 rows. The question is, how will SquirrelSql deal with really big result sets (millions of rows)...
Run from your GUI:
COPY (SELECT * FROM some_table) TO '/some/path/some_table.csv' WITH CSV HEADER
Using Squirrel 3.5.0
The "Store SQL result as file" is great if you only have a simple Select query. A more complex one with parameters wont work.
Even trying to export a result of 600,000+ rows to a CSV file can also fail.
