• getPath() :will return the absolute or relative path of the File object, depending on which it was constructed with.
• getAbsolutePath(): will return the current directory name concatenated with the file separator character and the path name of the file
• getCanonicalPath(): will return a path name with the relative references resolved.

Oracle Export : Using QUERY parameter in expdp/impdp

Oracle Export : Using QUERY parameter in expdp/impdp

expdp test/test directory=test_dir dumpfile=test.dmp query=emp:\"where salary\>10000\ order by salary" tables=emp

Easy a would be pass the query parameter through a file.

exp test@testdb tables=test_export parfile=test_query.par

Inside of test_query.par, it contains only one parameter query: 

Query=”where salary >10000  order by salary"
