How to Add a Boolean Column in Android SQlite

You could use something like this:

Create your table:

static final String CREATE_DB_TABLE = 
    "CREATE TABLE " + CONTACTS_TABLE_NAME " + 
    " (_id INTEGER PRIMARY KEY AUTOINCREMENT," + 
    "..." + " flag INTEGER DEFAULT 0)";

retrieve your value as:

Boolean flag = (cursor.getInt(cursor.getColumnIndex("flag")) == 1);

As mentioned by M D,

SQLite does not have a separate Boolean storage class. Instead,
Boolean values are stored as integers 0 (false) and 1 (true).

Use the following ALTER statement –

ALTER TABLE CREATE_DB_TABLE ADD status boolean NOT NULL default 0;

Then you can use Cursor to get the required value and then convert to actual boolean –

flag=cursor.getString(0).equals("1")

You can use this flag to display on user screen.

Reference: http://www.sqlite.org/datatype3.html

public enum Status{
        TRUE,FALSE;
}
static final String CREATE_DB_TABLE = 
  " CREATE TABLE " + CONTACTS_TABLE_NAME +
  " (_id INTEGER PRIMARY KEY AUTOINCREMENT, " +......
  " booleanColumn INTEGER DEFAULT 0);";

//while inserting

pass Status.TRUE.ordinal() values to database and

//while retrieving

cross check with the ordinal value for status

Sqlite does not provide any class to store boolean values.

You can use 0 for false and 1 for true. You will then have to convert these values after retrieving them from your database.

unfortunately android sqlite does not support Boolean type and you should use Integer instead of it
