What Makes a Valid SQLite Table Name?

Detailed explanation of SQLite table name rules

In SQLite databases, table names must follow specific naming rules to be considered valid. Unlike some other database systems, SQLite does not allow all combinations of alphanumeric characters to be valid table names.

Valid table name combinations

A valid SQLite table name must meet the following conditions:

• Starts with a letter (A-Z or a-z)

  For example, "Customers" or "product_orders" are valid table names.

• can be followed by any combination of alphanumeric characters (A-Z, a-z, 0-9)

  For example, "CustomerInformation" or "Products123" are valid table names.

Invalid table name

Table name cannot be:

• Starts with a number (0-9)

  For example, "123Orders" is not a valid table name.

• Contains special characters such as "-" or "."

  For example, "Customer-Orders" or "Product.Information" are not valid table names.

Table name using quotes

SQLite allows the use of quoted table names to bypass these restrictions. In this case, the table name can be enclosed in single or double quotes, for example:

• 'Customer-Orders'
• "Product.Information"

Other instructions:

• Table names enclosed in quotes can contain special characters or even spaces.
• Table names in SQLite are not case-sensitive.
• Table names cannot be reserved keywords, such as SELECT or UPDATE.

Following these naming conventions ensures that your table names are valid and identifiable within the SQLite database system.
