What is a collation sequence?

A collating sequence (also called a sort sequence) defines how characters in a character set relate to each other when they are compared and ordered. Different collating sequences are useful for those who want their data ordered for a specific language.

Does SQLite have sequences?

To create and access a sequence, you must use SQL functionality that is unique to the BDB SQL interface; no corresponding functionality exists in SQLite. The sequence functionality is implemented using SQLite function plugins, as such it is necessary to use the ‘select’ keyword as a prefix to all sequence APIs.

What is collate Nocase SQLite?

WHERE name = ‘someone’ COLLATE NOCASE. Additionaly, in SQLite, you can indicate that a column should be case insensitive when you create the table by specifying collate nocase in the column definition (the other options are binary (the default) and rtrim ; see here).

How is data stored in SQLite database?

The SQLite files are generally stored on the internal storage under /data/data//databases. SQLite databases are a rich source of forensic data. The built-in Android browser, based on the WebKit Open Source Project (http://webkit.org/), provides a great example.

Why collation is used in SQL Server?

Collations in SQL Server provide sorting rules, case, and accent sensitivity properties for your data. Collations that are used with character data types, such as char and varchar, dictate the code page and corresponding characters that can be represented for that data type.

What is collation Mongodb?

Collation allows users to specify language-specific rules for string comparison, such as rules for lettercase and accent marks. You can specify collation for a collection or a view, an index, or specific operations that support collation.

Is SQLite a relational database?

Overview and features. SQLite is an embedded, file-based RDBMS that does not require any installation or setup.

How does SQLite store time in database?

SQLite does not have a storage class set aside for storing dates and/or times. Instead, the built-in Date And Time Functions of SQLite are capable of storing dates and times as TEXT, REAL, or INTEGER values: TEXT as ISO8601 strings (“YYYY-MM-DD HH:MM:SS. SSS”).

Is SQLite query case sensitive?

Important Note: SQLite only understands upper/lower case for ASCII characters by default. The LIKE operator is case sensitive by default for unicode characters that are beyond the ASCII range. For example, the expression ‘a’ LIKE ‘A’ is TRUE but ‘æ’ LIKE ‘Æ’ is FALSE.

How do I start SQLite?

Start the sqlite3 program by typing “sqlite3” at the command prompt, optionally followed by the name the file that holds the SQLite database (or ZIP archive). If the named file does not exist, a new database file with the given name will be created automatically.

What makes a sequence of database operations a transaction?

A database transaction, by definition, must be atomic (it must either be complete in its entirety or have no effect whatsoever), consistent (it must conform to existing constraints in the database), isolated (it must not affect other transactions) and durable (it must get written to persistent storage).

What is the difference between SQLite and MySQL?

The big difference is SQLite is a app-resident library, while MySQL is typically used as a client-server DBMS where the client process interacts with the DB server process using some sort of networking. (Note that MySQL does have an app-resident usage mode, but it has a much bigger footprint than SQLite.)

How to check case-sensitivity in SQL Server?

Checking the Case-Sensitivity of SQL Server. We can write the keywords SELECT,FROM,WHERE,GROUP BY,etc.

Conclusion. The SQL case sensitivity can be set for non-keyword objects such as tables and columns by specifying the collation against the database,tables,and column level by mentioning CI
