Remarks
A SQLiteRawStatement
represents a SQLite prepared statement. The methods correspond very closely to SQLite APIs that operate on a sqlite_stmt object. In general, each API in this class corresponds to a single SQLite API.
A SQLiteRawStatement
must be created through a database, and there must be a transaction open at the time. Statements are implicitly closed when the outermost transaction ends, or if the current transaction is marked successful. Statements may be explicitly closed at any time with #close
. The #close
operation is idempotent and may be called multiple times without harm.
Multiple SQLiteRawStatement
s may be open simultaneously. They are independent of each other. Closing one statement does not affect any other statement nor does it have any effect on the enclosing transaction.
Once a SQLiteRawStatement
has been closed, no further database operations are permitted on that statement. An IllegalStateException
will be thrown if a database operation is attempted on a closed statement.
All operations on a SQLiteRawStatement
must be invoked from the thread that created it. A IllegalStateException
will be thrown if cross-thread use is detected.
A common pattern for statements is try-with-resources. <pre> // Begin a transaction. database.beginTransaction(); try (SQLiteRawStatement statement = database.createRawStatement("SELECT * FROM ...")) { while (statement.step()) { // Fetch columns from the result rows. } database.setTransactionSuccessful(); } finally { database.endTransaction(); } </pre>
Note that SQLiteRawStatement
is unrelated to SQLiteStatement
.
