Rename Table in SQLite 3.0

ALTER TABLE old_table_name RENAME TO new_table_name;

Replace old_table_name with the current name of the table you want to rename, and replace new_table_name with the desired new name.  

For example, if you have a table named "users" and you want to rename it to "profiles", you would use the following statement:

ALTER TABLE users RENAME TO profiles;

This will change the name of the table to "profiles" without affecting the data stored within it.

Using SQLite CLI:

2. Connect to the desired database file:

   sqlite3 your_database.db
   

3. Execute the ALTER TABLE statement:

   ALTER TABLE old_table_name RENAME TO new_table_name;
   

   For example:

   ALTER TABLE users RENAME TO profiles;
   

Using Python with the sqlite3 module:

1. Import the sqlite3 module.
2. Create a cursor object.
3. Execute the ALTER TABLE statement using the cursor's execute() method.
4. Commit the changes.
5. Close the connection.

Here's a complete example:

import sqlite3

conn = sqlite3.connect('your_database.db')
c = conn.cursor()

c.execute("ALTER TABLE users RENAME TO profiles")

conn.commit()
conn.close()

Using other programming languages:

The basic steps are similar for most programming languages. You typically need to:

1. Import the appropriate SQLite library or module.
2. Connect to the database.
3. Create a statement object or equivalent.
4. Commit the changes (if necessary).

Creating a New Table and Copying Data:

• Drop the old table.
• Use an INSERT INTO ... SELECT statement to copy the data from the old table to the new table.
• Create a new table with the desired name and structure.

This method can be useful if you need to modify the table structure (e.g., add or remove columns) in addition to renaming it. However, it can be more time-consuming for large tables.

Example:

CREATE TABLE new_table_name AS SELECT * FROM old_table_name;
DROP TABLE old_table_name;

Using a Database Management Tool:

Many database management tools (e.g., SQLiteStudio, DB Browser for SQLite) provide a graphical interface for renaming tables. This can be a convenient option if you prefer a visual approach.

Writing a Custom Script or Program:

You can create a script or program that uses the SQLite API to rename the table. This approach gives you more flexibility but requires programming knowledge.
