Create SQL table with the data from another table - sql

Question

How do I create a table using data which is already present in another table (copy of table)?

Answer 1

The most portable means of copying a table is to:
Create the new table with a CREATE TABLE statement
Use INSERT based on a SELECT from the old table:
INSERT INTO new_table
SELECT * FROM old_table
In SQL Server, I'd use the INTO syntax:
SELECT *
INTO new_table
FROM old_table
...because in SQL Server, the INTO clause creates a table that doesn't already exist.

If you are using MySQL, you may want to use the CREATE TABLE ... AS SELECT syntax to create a table defined by the columns and data types of another result set:
CREATE TABLE new_table AS
SELECT *
FROM old_table;
Example:
CREATE TABLE old_table (id int, value int);
INSERT INTO old_table VALUES (1, 100), (2, 200), (3, 300), (4, 400);
CREATE TABLE new_table AS
SELECT *
FROM old_table;
SELECT * FROM new_table;
+------+-------+
| id | value |
+------+-------+
| 1 | 100 |
| 2 | 200 |
| 3 | 300 |
| 4 | 400 |
+------+-------+
4 rows in set (0.00 sec)
DESCRIBE new_table;
+-------+---------+------+-----+---------+-------+
| Field | Type | Null | Key | Default | Extra |
+-------+---------+------+-----+---------+-------+
| id | int(11) | YES | | NULL | |
| value | int(11) | YES | | NULL | |
+-------+---------+------+-----+---------+-------+
2 rows in set (0.03 sec)

Answer 3

For SQL Server
SELECT *
INTO NewTable
FROM OldTable

Answer 4

For Sql server:
Create new table from existing table :
CREATE TABLE new_table_name AS
SELECT [col1,col2,...coln] FROM existing_table_name [WHERE condition];
Insert values into existing table form another existing table using Select command :
SELECT * INTO destination_table FROM source_table [WHERE conditions];
SELECT *
INTO newtable [IN externaldb]
FROM oldtable
[ WHERE condition ];
Insert values into existing table form another existing table using
Insert command :
INSERT INTO table2 (column1, column2, column3, ...)
SELECT column1,column2, column3, ... FROM table1 [WHERE condition];

Answer 5

if u want exact schema of existing table to new table and all values of existing table want to be inserted into your new table then execute below two queries :
create table new_table_name like Old_table_name;
select * into new_table_name from Old_table_name;
LIKE works only for base tables, not for views.
If the original table is a TEMPORARY table, CREATE TABLE ... LIKE does not preserve TEMPORARY. To create a TEMPORARY destination table, use CREATE TEMPORARY TABLE ... LIKE.
