A quickie: I had to dump all the data from an Oracle database and e-mail them to a colleague. Not being familiar with backup and restore for Oracle, I decided to just run exp for each of the tables. To get a list of tables in a schema, I executed this query in DbVisualizer, SELECT TABLE_NAME FROM ALL_TABLES WHERE OWNER = '<schema>', and saved the output to a file, table.txt. Then in Windows cmd, I wrote this script into a file and ran it:
for /f %%i in (table.txt) do exp <connection string> TABLES=%%i FILE=%%i
