amazon-redshiftHow do I replace a table in Amazon Redshift?
To replace a table in Amazon Redshift, you can use the CREATE TABLE AS
command. This command creates a new table with the same structure as the original table and inserts the data from the original table into the new table. The following example code creates a new table called new_table
from an existing table called old_table
:
CREATE TABLE new_table AS
SELECT *
FROM old_table;
This command will create a new table with the same structure as old_table
and insert the data from old_table
into new_table
.
You can also use the CREATE TABLE AS
command to replace a table with a modified version of the original table. The following example code creates a new table called new_table
with modified data from an existing table called old_table
:
CREATE TABLE new_table AS
SELECT col1, col2, col3
FROM old_table
WHERE col3 > 5;
This command will create a new table with the same structure as old_table
but only include data where col3
is greater than 5.
For more information on the CREATE TABLE AS
command, you can refer to the Amazon Redshift Documentation.
