The result set will contain one row for each column contained in the index giving column sequence, column index with-in table and column name. The index_info pragma returns information about a database index. The format value can be one of UTF-8, UTF-16le, or UTF-16be. The freelist_count pragma returns a single integer indicating how many database pages are currently marked as free and available. The encoding pragma controls how strings are encoded and stored in a database file. This pragma will return a three-column table with one row per open or attached database giving database sequence number, its name and the file associated. The database_list pragma will be used to list down all the databases attached. If set to true, each of the mentioned statement will return a one-column, one-row table consisting of a single integer value indicating impacted rows by the operation. Following is the simple syntax.īy default, this pragma is false and these statements do not return anything. count_changes PragmaĬount_changes pragma gets or sets the return value of data manipulation statements such as INSERT, UPDATE and DELETE. There is no way to query for the current state of this pragma. By default, this pragma is false which means that the built-in LIKE operator ignores the letter case. The case_sensitive_like pragma controls the case-sensitivity of the built-in LIKE expression. The built-in page cache has a default size of 2,000 pages and a minimum size of 10 pages. The pages value represents the number of pages in the cache. The cache_size pragma can get or temporarily set the maximum size of the in-memory page cache. These pages can be recovered using the incremental_vacuum pragma any time. In this mode the reference data is maintained, but free pages are simply put on the free list. This is the default mode which means that a database file will never shrink in size unless it is manually vacuumed using the VACUUM command.Īuto-vacuum is enabled and fully automatic which allows a database file to shrink as data is removed from the database.Īuto-vacuum is enabled but must be manually activated. Where mode can be any of the following − Sr.No.Īuto-vacuum is disabled. The auto_vacuum pragma gets or sets the auto-vacuum mode. The set mode can be either the name or the integer equivalent but the returned value will always be an integer. To set a new value for PRAGMA, use the following syntax. To query the current PRAGMA value, just provide the name of the pragma. A PRAGMA value can be read and it can also be set based on the requirements.
