Remarks

Exposes methods to manage a SQLite database.

SQLiteDatabase has methods to create, delete, execute SQL commands, and perform other common database management tasks.

See the Notepad sample application in the SDK for an example of creating and managing a database.

Database names must be unique within an application, not across all applications.

<h3>Localized Collation - ORDER BY</h3>

In addition to SQLite's default BINARY collator, Android supplies two more, LOCALIZED, which changes with the system's current locale, and UNICODE, which is the Unicode Collation Algorithm and not tailored to the current locale.

Constructors

SQLiteDatabase(IntPtr, JniHandleOwnership)

A constructor used when creating managed representations of JNI objects; called by the runtime.

Fields

ConflictAbort	Obsolete. When a constraint violation occurs,no ROLLBACK is executed so changes from prior commands within the same transaction are preserved.
ConflictFail	Obsolete. When a constraint violation occurs, the command aborts with a return code SQLITE_CONSTRAINT.
ConflictIgnore	Obsolete. When a constraint violation occurs, the one row that contains the constraint violation is not inserted or changed.
ConflictNone	Obsolete. Use the following when no conflict action is specified.
ConflictReplace	Obsolete. When a UNIQUE constraint violation occurs, the pre-existing rows that are causing the constraint violation are removed prior to inserting or updating the current row.
ConflictRollback	Obsolete. When a constraint violation occurs, an immediate ROLLBACK occurs, thus ending the current transaction, and the command aborts with a return code of SQLITE_CONSTRAINT.
JournalModeDelete	The DELETE journaling mode is the normal behavior.
JournalModeMemory	The MEMORY journaling mode stores the rollback journal in volatile RAM.
JournalModeOff	The OFF journaling mode disables the rollback journal completely.
JournalModePersist	The PERSIST journaling mode prevents the rollback journal from being deleted at the end of each transaction.
JournalModeTruncate	The TRUNCATE journaling mode commits transactions by truncating the rollback journal to zero-length instead of deleting it.
JournalModeWal	The WAL journaling mode uses a write-ahead log instead of a rollback journal to implement transactions.
MaxSqlCacheSize	Absolute max value that can be set by #setMaxSqlCacheSize(int).
SqliteMaxLikePatternLength	Maximum Length Of A LIKE Or GLOB Pattern The pattern matching algorithm used in the default LIKE and GLOB implementation of SQLite can exhibit O(N^2) performance (where N is the number of characters in the pattern) for certain pathological cases.
SyncModeExtra	The EXTRA sync mode is like FULL sync mode with the addition that the directory containing a rollback journal is synced after that journal is unlinked to commit a transaction in DELETE journal mode.
SyncModeFull	In FULL sync mode the SQLite database engine will use the xSync method of the VFS to ensure that all content is safely written to the disk surface prior to continuing.
SyncModeNormal	The NORMAL sync mode, the SQLite database engine will still sync at the most critical moments, but less often than in FULL mode.
SyncModeOff	In OFF sync mode SQLite continues without syncing as soon as it has handed data off to the operating system.
