◆ bindValue()

bool SqlitePreparedStatement::bindValue ( KDbField * field,

optimize: make a static copy so SQLITE_STATIC can be used
what about unsigned > INT_MAX ?
what about unsigned > LLONG_MAX ?

◆ execute()

QSharedPointer< KDbSqlResult > SqlitePreparedStatement::execute ( KDbPreparedStatement::Type type,
const KDbField::List & selectFieldList,
KDbFieldList * insertFieldList,
const KDbPreparedStatementParameters & parameters )

For implementation, executes the prepared statement Type of statement is specified by the type parameter.

selectFieldList specifies fields for SELECT statement. insertFieldList is set to list of fields in INSERT statement. Parameters parameters are passed to the statement, usually using binding.

Implements KDbPreparedStatementInterface.

◆ prepare()

bool SqlitePreparedStatement::prepare ( const KDbEscapedString & sql)

For implementation. Initializes the prepared statement in a backend-dependent way using recently generated sql statement. It should be guaranteed that sql is valid and not empty. For example sqlite3_prepare() is used for SQLite. This is called only when d->dirty == true is encountered on execute(), i.e. when attributes of the object (like WHERE field names) change.

Implements KDbPreparedStatementInterface.
