Copying data between Oracle schemas using SQL

Question

I'm trying to copy data from one Oracle schema (CORE_DATA) into another (MY_DATA) using an 'INSERT INTO (...)' SQL statement.

What would the SQL statement look like?

Thanks,

Answer 1

Prefix your table names with the schema names when logged in as a user with access to both:

insert into MY_DATA.table_name select * from CORE_DATA.table_name;

Assuming that the tables are defined identically in both schemas, the above will copy all records from the table named table_name in CORE_DATA to the table named table_name in MY_DATA.

Answer 2

your schema must have grant create any table privilege for this

Answer 3

usage: COPY FROM [db] TO [db] [opt] [table] { ([cols]) } USING [sel]
[db] : database schema string, e.g., grprass/grprass@grprass, pplan/pplan@prassm1
[opt] : ONE of the keywords: APPEND, CREATE, INSERT or REPLACE
[table]: name of the destination table
[cols] : a comma-separated list of destination column aliases ( optional )
[sel] : any valid SQL SELECT statement

SQL> COPY FROM scott/tiger@schema1 TO scott/tiger@schema2 insert mytable using select * from mytable;
