Is SQLite case-insensitive?

Is SQLite case-insensitive?

The default configuration of SQLite only supports case-insensitive comparisons of ASCII characters.

When using SQLite what datatypes can you assign to a column when creating a new table select all that apply?

Each column in an SQLite 3 database is assigned one of the following type affinities:

• TEXT.
• NUMERIC.
• INTEGER.
• REAL.
• BLOB.

Is SQLite strongly typed?

SQLite is very flexible with regard to datatypes. Some commentators say that SQLite is “weakly typed” and that other SQL databases are “strongly typed”. Instead, SQLite stores the actual string value in the column. Similarly, SQLite allows you to store a 2000-character string into a column of type VARCHAR(50).

What is the difference between int and INTEGER in SQLite?

Yes, there is a difference: INTEGER is a special case in SQLite, when the database does not create a separate primary key, but reuses the ROWID column instead. When you use INT (or any other type that “maps” to INTEGER internally) a separate primary key is created.

Does SQLite support multiple connections?

3 Answers. Yes SQLite can support multiple users at once. It does however lock the whole database when writing, so if you have lots of concurrent writes it is not the database you want (usually the time the database is locked is a few milliseconds – so for most uses this does not matter).

Which SQLite data type is used to hold the string?

SQLite storage class is slightly more general than a datatype. The INTEGER storage class, for example, includes 6 different integer datatypes of different lengths….SQLite Storage Classes.

Sr.No.	Storage Class & Description
4	TEXT The value is a text string, stored using the database encoding (UTF-8, UTF-16BE or UTF-16LE)

How is a text string converted to an integer in SQLite?

For example, if a column has a datatype of “INTEGER” and the application inserts a text string into that column, SQLite will first try to convert the text string into an integer, just like every other SQL database engine. Thus, if one inserts ‘1234’ into an INTEGER column, that value is converted into an integer 1234 and stored.

Can you ignore the artistid column in SQLite?

Because the ArtistId column is an auto-increment column, you can ignore it in the statement. SQLite automatically geneate a sequential integer number to insert into the ArtistId column. You can verify the insert operation by using the following SELECT statement: As you see, we have a new row in the artists table.

Which is more general integer or datatype in SQLite?

The value is a text string, stored using the database encoding (UTF-8, UTF-16BE or UTF-16LE). BLOB. The value is a blob of data, stored exactly as it was input. A storage class is more general than a datatype. The INTEGER storage class, for example, includes 6 different integer datatypes of different lengths.

Is there a NOT NULL column in SQLite?

Based on the SQL standard, PRIMARY KEY should always imply NOT . However, SQLite allows NULL values in the PRIMARY KEY column except that a column is INTEGER PRIMARY KEY column or the table is a WITHOUT ROWID table or the column is defined as a NOT NULL column. This is due to a bug in some early versions.
