I want to migrate my tables from Oracle to Postgres.
The COPY FROM command can take input from 'file' or 'STDIN'.
Is it possible for the COPY command to take its input from a
java program(which contains the oracle resultset) or any other way?
"STDIN" just means from the same place as the rest of the SQL has come
from. For example, if you're using JDBC, it would be possible do
generate a string containing:
COPY tbl (col1,col2) FROM STDIN WITH CSV; 1,2 4,7 12,37 \.
and execute() the whole string. There appear to be patches[1] available so
you can stream directly into the database rather than having to generate
a large strings to pass in.
