Definition at line 367 of file qsql_firebird_helpers.cpp.

◆ encodeTextValue()

void encodeTextValue ( char * data,
int fbType,
qsizetype length,
const QByteArray & bytes )

Encode a UTF-8 string into a CHAR/VARCHAR message slot: VARYING gets a 2-byte length prefix, TEXT is space-padded; data beyond the declared length is truncated. Shared by fillInputBuffer and lookupArrayDesc's bind loop so the Firebird text wire format lives in one place.

Definition at line 460 of file qsql_firebird_helpers.cpp.

◆ fbError()

QSqlError fbError ( IMaster * master,
IStatus * status,
QSqlError::ErrorType type )

Convert a Firebird status vector into a QSqlError. type is the context in which the error occurred, supplied by the caller (open() -> ConnectionError, prepare()/exec() -> StatementError, begin/commit/rollback -> TransactionError); QSqlError::ErrorType categorises errors by that context, not by the underlying Firebird cause. The SQLCODE is carried through as the native error code.

Definition at line 53 of file qsql_firebird_helpers.cpp.

◆ fbErrorString()

Here is the call graph for this function:

◆ finishAndClear()

void finishAndClear ( Firebird::ThrowStatusWrapper & st,
Firebird::ITransaction *& tr,
TxnEnd end )

Commit (or roll back) a transaction whose handle must not outlive a failure: on a throw the interface is released and the member cleared before the rethrow, on success commit/rollback already released it, so the member is cleared too. Taking the handle by reference makes "released implies cleared" structural — every finish site shares this discipline instead of repeating it. (The bare-COMMIT path in exec() intentionally does NOT use this: a failed user COMMIT keeps the still-valid handle so it can be retried.)

Definition at line 74 of file qsql_firebird_helpers.cpp.

◆ fromFirebirdZoneId()

QTimeZone fromFirebirdZoneId ( const QByteArray & id)
static

Definition at line 336 of file qsql_firebird_helpers.cpp.

◆ int128SlotToString()

QString int128SlotToString ( const char * slot,
int scale,
IMaster * master,
IStatus * status )
static

Definition at line 176 of file qsql_firebird_helpers.cpp.

◆ startDefaultTransaction()

ITransaction * startDefaultTransaction ( IAttachment * att,
ThrowStatusWrapper & st,
TxnWait wait )

Start a transaction with the driver's default TPB: read-committed, record-version, read-write. wait selects isc_tpb_wait vs isc_tpb_nowait — the only axis on which the auto-started transaction (wait) and the explicit user transaction (nowait) differ.

Definition at line 96 of file qsql_firebird_helpers.cpp.

◆ toFirebirdZoneId()

QByteArray toFirebirdZoneId ( const QTimeZone & zone)
static

Firebird names fixed-offset zones by their bare displacement ("+05:30"), while Qt uses "UTC+05:30"-style ids for them. Map between the two so offset-tagged QDateTimes bind and read back cleanly.
