sqliteHow do I use an enum data type with SQLite?

Enums are data types that allow you to define a list of valid values for a given column in a SQLite database. To use an enum data type in SQLite, you need to use the CREATE TABLE statement to create a table with the desired column. The syntax for creating a column with an enum data type is as follows:

CREATE TABLE table_name (
  column_name ENUM('value1', 'value2', 'value3', ...)
);

For example, if you wanted to create a table with a column that only accepts values of 'yes' or 'no', you could do the following:

CREATE TABLE responses (
  answer ENUM('yes', 'no')
);

Once the table is created, you can use the INSERT statement to add data to the table. The syntax for the INSERT statement is as follows:

INSERT INTO table_name (column_name)
VALUES ('value');

For example, if you wanted to insert a 'yes' value into the responses table, you could do the following:

INSERT INTO responses (answer)
VALUES ('yes');

You can also use the SELECT statement to query data from the table. The syntax for the SELECT statement is as follows:

SELECT column_name
FROM table_name;

For example, if you wanted to get all the values from the responses table, you could do the following:

SELECT answer
FROM responses;

This would return all the values from the responses table, which in this case would be 'yes' and 'no'.
