In MySQL, how to copy the content of one table to another table within the same database?

Question

I am new to MySQL. I would like to copy the content of one table to another table within the same database. Basically, I would like to insert to a table from another table.

Answer 1

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

Answer 2

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;

Answer 3

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;

Answer 4

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

Answer 5

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

Answer 6

Try this. Works well in my Oracle 10g,

CREATE TABLE new_table
  AS (SELECT * FROM old_table);
