An SQLite3 connection.
This class provides the backend implementation for SQLite3 databases.
Configuration of date time storage.
SQlite3 does not provide real type support for date time. Instead, it offers 3 choices for storing a date time, each of these compatible with the use of the built-in arithmetic functions.
| ISO8601AsText | As 'text' in ISO8601 format. This also interprets correctly dates stored in the database using the PseudoISO8601AsText format. | 
| PseudoISO8601AsText | As 'text' in ISO8601-like format, but using a space (' ') instead of 'T' as a separator character between date and time. This is the behaviour of Wt::Dbo prior to Wt 3.2.3. This also interprets correctly dates stored in the database using the ISO8601AsText format. | 
| JulianDaysAsReal | As 'real', the number of julian days. Note that this does not support second accuracy for a date time, but is the preferred format for a plain date. | 
| UnixTimeAsInteger | As 'integer', number of seconds since UNIX Epoch. | 
| Wt::Dbo::backend::Sqlite3::Sqlite3 | ( | const std::string & | db | ) | 
Opens a new SQLite3 backend connection.
The db may be any of the values supported by sqlite3_open(). 
| Wt::Dbo::backend::Sqlite3::~Sqlite3 | ( | ) | 
Destructor.
Closes the connection.
| std::vector< std::string > Wt::Dbo::backend::Sqlite3::autoincrementCreateSequenceSql | ( | const std::string & | table, | 
| const std::string & | id | ||
| ) | const  [virtual] | 
Returns the SQL statement(s) required to create an id sequence.
This is used by Session::createTables() to create the id sequence for a table. The table's name and primary key are passed as arguments to this function and can be used to construct an SQL sequence that is unique for the table.
Implements Wt::Dbo::SqlConnection.
| std::vector< std::string > Wt::Dbo::backend::Sqlite3::autoincrementDropSequenceSql | ( | const std::string & | table, | 
| const std::string & | id | ||
| ) | const  [virtual] | 
Returns the SQL statement(s) required to drop an id sequence.
This is used by Session::dropTables() to drop the id sequence for a table. The table's name and primary key are passed as arguments to this function and can be used to construct an SQL sequence that is unique for the table.
Implements Wt::Dbo::SqlConnection.
| std::string Wt::Dbo::backend::Sqlite3::autoincrementInsertSuffix | ( | ) | const  [virtual] | 
Returns the suffix for an 'autoincrement' insert statement.
This is appended to the insert statement, since some back-ends need to be indicated that they should return the autoincrement id. 
Implements Wt::Dbo::SqlConnection.
| std::string Wt::Dbo::backend::Sqlite3::autoincrementSql | ( | ) | const  [virtual] | 
Returns the 'autoincrement' SQL type modifier.
This is used by Session::createTables() to create the id column.
Implements Wt::Dbo::SqlConnection.
| std::string Wt::Dbo::backend::Sqlite3::autoincrementType | ( | ) | const  [virtual] | 
Returns the 'autoincrement' SQL type.
This is used by Session::createTables() to create the id column.
Implements Wt::Dbo::SqlConnection.
| const char * Wt::Dbo::backend::Sqlite3::blobType | ( | ) | const  [virtual] | 
Returns the blob type.
Implements Wt::Dbo::SqlConnection.
| Sqlite3 * Wt::Dbo::backend::Sqlite3::clone | ( | ) | const  [virtual] | 
Clones the connection.
Returns a new connection object that is configured like this object. This is used by connection pool implementations to create its connections.
Implements Wt::Dbo::SqlConnection.
| void Wt::Dbo::backend::Sqlite3::commitTransaction | ( | ) |  [virtual] | 
| const char * Wt::Dbo::backend::Sqlite3::dateTimeType | ( | SqlDateTimeType | type | ) | const  [virtual] | 
Returns the date/time type.
Implements Wt::Dbo::SqlConnection.
| SqlStatement * Wt::Dbo::backend::Sqlite3::prepareStatement | ( | const std::string & | sql | ) |  [virtual] | 
| void Wt::Dbo::backend::Sqlite3::rollbackTransaction | ( | ) |  [virtual] | 
Rolls back a transaction.
This function rolls back a transaction.
Implements Wt::Dbo::SqlConnection.
| void Wt::Dbo::backend::Sqlite3::setDateTimeStorage | ( | SqlDateTimeType | type, | 
| DateTimeStorage | format | ||
| ) | 
Configures how to store date or date time.
The default format is ISO8601AsText.
