ConclusionĪs a developer, it is always essential to understand the available options and make informed decisions based on the project's specific requirements. How can I add a Boolean field to MySQL MySQL MySQLi Database You can use tinyint (1) or bool or boolean. ![]() This is another reason why using a slightly larger column doesn't matter that much, as it's unlikely to be indexed. Most posts won't be archived, so querying for posts that aren't archived will not use the index. If we decide to put an index on the is_archived column, it is unlikely to be selective enough to benefit the query. In a large database, the extra space usage can be significant but it usually doesn't make too much of a difference. When I wrote a two-way sync between FMP and MySQL, I had to translate between field types between the two databases. As a result, when using timestamps, we need to be mindful of the amount of storage space we use. While using timestamps provides us with extra information, it has a few tradeoffs that we must consider.Ī timestamp column uses four times more storage space than a boolean column, which uses only one byte. However, the archived_at column provides us with more information, namely the time at which the post was archived, which could be useful in the long run. However unlike in other databases, when you perform such actions you will need to use 1 and 0 rather than TRUE and FALSE.SELECT * FROM posts WHERE is_archived = false They can be created using the CREATE TABLE statement, and data can be inserted, retrieved, and manipulated using a variety of SQLite statements, such as SELECT, INSERT INTO, UPDATE, and DELETE. In conclusion, Boolean columns in SQLite are useful for storing data that has a binary nature. You can also use the DELETE statement to remove rows from the table where the value in the Boolean column is true or false. For example, you can use the UPDATE statement to change the value in a Boolean column from true to false or vice versa. In addition to using the SELECT statement to retrieve data from a Boolean column, you can also use it to manipulate the data. You can also use the SELECT statement to retrieve rows where the value in the Boolean column is false (represented by the integer 0). This would return all rows from the table where the value in the Boolean column is true (represented by the integer 1). SELECT * FROM table_name WHERE column_name = 1 Yum.Įxpand your database knowledge with our technical blog. Learn how to use Beekeeper Studio with bite-sized articles.
