I am trying to dump the schema and data from an existing Oracle DB and import it into another Oracle DB.
I have tried using the "Export Wizard" provided by sqldeveloper.
I found answers using Oracle Data Pump, however i do not have access to the filesystem of the DB server.
I expect to get a file that i can copy and import into another DB
Without Data Pump, you have to make some concessions.
The biggest concession is you're going to ask a Client application, running somewhere on your network, to deal with a potentially HUGE amount of data/IO.
Withing reasonable limits, you can use the Tools > Database Export wizard to build a series of SQLPlus style scripts, both DDL (CREATEs) and DATA (INSERTs).
Once you have those scripts, you can use SQLPlus, SQLcl, or SQL Developer to run them on your new/target database.

I'm trying to import a .dmp file using the Data Pump Import tool in oracle sql developer.
I'm connected to an oracle database running in a container on my local machine.
When I get to the step where I specify where the dump file is to import, where should I place the .dmp file?
DATA_PUMP_DIR is a default Oracle directory object. It isn't part of SQL Developer; the import tool is really just giving you a GUI equivalent of running impdp from the command line.
You can find the operating system location that Oracle directory object points to by querying the data dictionary:
select directory_path from all_directories where directory_name = 'DATA_PUMP_DIR';
The path that returns is on the database server (in your case that'll be inside your container too), and your dump file needs to go there.
You might want to create additional directory objects pointing to other locations, and grant suitable privileges to users to be able to access them; but they all need to be on the DB server and read/writable by the Oracle process owner on that server.
(They could be remote filesystems mounted on the server, they don't necessarily have to be local storage, but that's another issue and more operating-system specific. Again, in your case, you might be able to share a folder on your local machine with the container, if you don't want to copy the file into the container.)
I'm looking to bulk loads millions of rows into a DashDB database. After connecting using the DB2 CLI, I enter a command like:
db2 import from rowsToImport.csv of del insert into MY_TABLE
with results:
SQL0551N "DASHXXX" does not have the required authorization or privilege to
perform operation "BIND" on object "NULLID.SQLUAJ19". SQLSTATE=42501
Is this an inherent limitation with DashDB, or is something configured incorrectly on my client? I get a similar message when trying db2 load:
SQL2019N An error occurred while utilities were being bound to the database.
p.s. I'm aware of the rest client api for DashDB for loading data - I'm asking specifically how/if bulk loads can be done with the DB2 command line as an alternate option.
As per dashDB documentation you can use the Command line processor plus (CLPPlus). It is included in the dashDB driver package and provides a command-line user interface that you can use to connect to the dashDB database, BLUDB. You can use CLPPlus to define, edit, and run statements, scripts, and commands. Please take also a look at Connecting CLPPlus to the dashDB database to see how to connect and use the CLI.
Please note that in CLPPlus: IMPORT, EXPORT and LOAD commands have a restriction that processed files must be on the server: see here. So you should copy the input load file onto the remote server first with SCP. However SSH/SCP protocol should be blocked (not accessible) for a normal dashDB user.
Only geospatial data can be loaded from your local machine to dashDB, using IDA LOADGEOSPATIALDATA command in CLPPlus.
The file to be loaded in dashDB using the above command can be in the local file system, accessible to the CLPPlus user.
Alternative ways to do that are:
dashDB REST API (as you already mentioned). See Load delimited data using the REST API and cURL.
load the csv directly from the dashDB dashboard on Bluemix. See Loading data from the desktop into IBM dashDB.
load the csv using IBM Data Studio. See dashDB large file load using IBM Data Studio.
According to this technote, the package NULLID.SQLUAJ19 belongs to one of the early DB2 10.1 fix packs, so I suspect your client version is 10.1. When attempting to execute the IMPORT command it needs to bind some packages of that older version, since dashDB is DB2 10.5, obvisouly.
You may want to try installing the latest DB2 client fix pack, as the necessary packages may be already bound in the database.
To verify that you could run select pkgname from syscat.packages where pkgschema = 'NULLID' and pkgname like 'SQLUA%' -- you should see "SQLUAK20", which seems to be the corresponding package in DB2 10.5.
If that doesn't work, your other option might be to move to a dedicated dashDB instance, as you won't have sufficient privileges to bind missing packages in the entry-level shared dashDB service.
I need to export all tables from SQL Server to PostgreSQL.
Try: I tried from SQL Server IDE but at some stage its giving the error about data types are different.
Question:How can I do export of data from SQL Server to PostgreSQL? Is COPY does my job? If yes, then how can I export all tables including records?
You can't export data from MSsql then import to PostgreSql because it is not same syntax, data type, but you can use tool to migration data from mssql to postgreSql,
See more in topic
migrate data from MS SQL to PostgreSQL?
Use https://dbeaver.io/
Create MS SQL and PostgreSQL database connections (login)
Create target tables in PostgreSQL (same structures in MS SQL)
F5 to see new tables
Right-click on new tables -> 'Import Data' -> You will see 'Data Transfer' window
Choose 'Table' type then click 'Next' -> You will see 'Select input object', where you can choose tables from MS SQL connection
Just 'next' and check settings that you need, done :D
First export the schema into a file and run it against PostgreSQL until you've removed all incompatibilities.
You could try to do the same with the data you want to export but you may be better off writing a Python script to migrate it.
There is an absolutely simple way using built-in SSIS tool using Management Studio. You can find the detailed answer here.
Use https://dbeaver.io/ , as An Le mentioned.
After 40 years of DB development, migrating DB data is still a challenge. DBeaver is a free tool to use for data migration. But you still have to migrate the schema.
Exporting data from DBeaver
From contextual menu of your SQLServer database or schema select Tools > Create new Task > Common > Data Export
You will generate SQL insert files or CSV files. For migration between database types use CSV files.
Cons of SQL Server Migration Tool
Unable to migrate rows containing booleans.
Export ended up in errors of migrationg data with Bool columns, complaining that value is not boolean, although both source and destination columns where of boolean type.
Unable to continue with the next tables afer one table migration fails.
SQL Server - A single error stops all migration even for tables that are not related to the initial error.
Configuring the tool over and over again, trying to export your data is a waste of time. SQL Server migration task does not save the configuration of the source and destination connections. And the wizard is not user friendly, spending your time on it is frustrating. I assume the migration project was abandoned for at least 10 years.
I have oracle 10g enterprise edition. I want to perform table backup and full database backup to .sql files to be able to move to another server/PC ...
If possible, image explanation ...
If you want to move to a different Oracle server, you should use:
expdp
To export your data. And:
impdp
To import it on the other database. Here's a WIKI entry that might help you. It's the easy way of moving data around Oracle servers.
On the other hand, ff you want to move your data to a different DATABASE SERVER (not Oracle branded) you would need some sort of translator in the way.
what is the difference between .rdb and .sqlite?
An .RDB is most likely a Oracle database system which uses SQL commands to access its content. Being simplistic, its big, heavy and powerful and requires servers and services to run and use.
You might look at MySQL for an RDB which carries less weight.
A .sqlite database is a self contained file which can be accessed with an sqlite client or in OS X via the CoreData framework.
The sqlite client also uses SQL commands to access its content but only a subset of the commands that are available to 'true' RDB databases like MySQL or Oracle.
Check out http://www.sqlite.org/ for more info.
A few years later it's also noteworthy that Redis uses the .RDB file extension for its dumps (via SAVE or BGSAVE commands).
