Try this  Works well in my Oracle 10g   CREATE TABLE new table   AS  SELECT   FROM old table

If table1 is large and you don t want to lock it for the duration of the copy process  you can do a dump-and-load instead   CREATE TABLE table2 LIKE table1   SELECT   INTO OUTFILE   tmp table1 txt  FROM table1  LOAD DATA INFILE   tmp table1 txt  INTO TABLE table2

This worked for me  You can make the SELECT statement more complex  with WHERE and LIMIT clauses    First duplicate your large table  without the data   run the following query  and then truncate the larger table   INSERT INTO table small  SELECT   FROM table large WHERE column    value  LIMIT 100    Super simple   -

If you want to create and copy the content in a single shot  just use the SELECT  CREATE TABLE new tbl SELECT   FROM orig tbl

INSERT INTO TARGET TABLE SELECT   FROM SOURCE TABLE   EDIT  or if the tables have different structures you can also   INSERT INTO TARGET TABLE   col1   col2   SELECT  col1   col2  FROM SOURCE TABLE    EDIT  to constrain this    INSERT INTO TARGET TABLE   col1    col2    SELECT  col1   col2  FROM SOURCE TABLE WHERE  foo  1

This worked for me   CREATE TABLE newtable LIKE oldtable   Replicates newtable with old table  INSERT newtable SELECT   FROM oldtable   Copies all the row data to new table   Thank you

CREATE TABLE target table SELECT   FROM source table   It just create a new table with same structure as of source table and also copy all rows from source table into target table  CREATE TABLE target table SELECT   FROM source table WHERE condition   If you need some rows to be copied into target table  then apply a condition inside where  clause

If the table doesn t exist  you can create one with the same schema like so   CREATE TABLE table2 LIKE table1    Then  to copy the data over   INSERT INTO table2 SELECT   FROM table1
