Member Function Documentation

◆ drv_closeDatabase()

bool xBaseConnection::drv_closeDatabase ( )

protectedvirtual

For implementation: closes previously opened database using connection.

Implements KDbConnection.

Definition at line 94 of file XbaseConnection.cpp.

◆ drv_connect()

bool xBaseConnection::drv_connect ( KDbServerVersionInfo * version )

protectedvirtual

Todo: xBase version here

Definition at line 37 of file XbaseConnection.cpp.

◆ drv_containsTable()

bool xBaseConnection::drv_containsTable ( const QString & tableName )

protectedvirtual

Todo: move this somewhere to low level class (MIGRATION?)

Implements KDbConnection.

Definition at line 148 of file XbaseConnection.cpp.

◆ drv_createDatabase()

bool xBaseConnection::drv_createDatabase ( const QString & dbName = QString() )

protectedvirtual

For implementation: creates new database using connection

Todo: Check whether this function has any use.

Implements KDbConnection.

Definition at line 79 of file XbaseConnection.cpp.

◆ drv_disconnect()

bool xBaseConnection::drv_disconnect ( )

protectedvirtual

For implementation: disconnects database

Returns: true on success.

Implements KDbConnection.

Definition at line 50 of file XbaseConnection.cpp.

◆ drv_dropDatabase()

bool xBaseConnection::drv_dropDatabase ( const QString & dbName = QString() )

protectedvirtual

For implementation: drops database from the server using connection. After drop, database shouldn't be accessible anymore.

Todo: is here escaping needed

Implements KDbConnection.

Definition at line 101 of file XbaseConnection.cpp.

◆ drv_executeSql()

bool xBaseConnection::drv_executeSql ( const KDbEscapedString & sql )

protectedvirtual

Executes query for a raw SQL statement sql without returning resulting records.

It is useful mostly for INSERT queries but it is possible to execute SELECT queries when returned records can be ignored. The @sql should be is valid and properly escaped.

Note: Only use this method if you really need.

See also: executeSql

Implements KDbConnection.

Definition at line 108 of file XbaseConnection.cpp.

◆ drv_getDatabasesList()

bool xBaseConnection::drv_getDatabasesList ( QStringList * list )

protectedvirtual

For reimplementation: loads list of databases' names available for this connection and adds these names to list. If your server is not able to offer such a list, consider reimplementing drv_databaseExists() instead. The method should return true only if there was no error on getting database names list from the server. Default implementation puts empty list into list and returns true.

See also: databaseNames

Todo: Check whether this is the right thing to do

Reimplemented from KDbConnection.

Definition at line 71 of file XbaseConnection.cpp.

◆ drv_getTablesList()

bool xBaseConnection::drv_getTablesList ( QStringList * list )

protectedvirtual

Todo: move this somewhere to low level class (MIGRATION?)

Definition at line 154 of file XbaseConnection.cpp.

◆ drv_lastInsertRecordId()

quint64 xBaseConnection::drv_lastInsertRecordId ( )

protectedvirtual

Definition at line 112 of file XbaseConnection.cpp.

◆ drv_useDatabase()

bool xBaseConnection::drv_useDatabase	(	const QString &	dbName = QString(),
		bool *	cancelled = 0,
		KDbMessageHandler *	msgHandler = 0 )

protectedvirtual

For implementation: opens existing database using connection

Returns: true on success, false on failure; sets cancelled to true if this action has been cancelled.

Todo: is here escaping needed?

Implements KDbConnection.

Definition at line 86 of file XbaseConnection.cpp.

◆ prepareQuery() [1/2]

		int	cursor_options = 0 )

Todo: returns nullptr for now

Todo: return new XBasePreparedStatement(*d);

Implements KDbConnection.

Definition at line 163 of file XbaseConnection.cpp.
