Detailed Description

The KDbConnectionProxy class gives access to protected (low-level) API of KDbConnection.

The connection object specified in constructor of the proxy is called a parent connection. All inherited methods of the KDbConnection API call equivalent methods of the parent connection. The KDbConnectionProxy class also provides non-virtual methods that are equivalent to KDbConnection ones. These KDbConnection's equivalent methods are called by the proxy too.

Example use of this class is Kexi's database database migration plugins when the source database is only accessibly using low-level routines.

Constructor & Destructor Documentation

◆ KDbConnectionProxy()

KDbConnectionProxy::KDbConnectionProxy ( KDbConnection * connection)
explicit

Creates a proxy object for parent connection.

connection must not be nullptr. It is owned by this proxy unless setConnectionIsOwned(false) is called.

Definition at line 44 of file KDbConnectionProxy.cpp.

◆ ~KDbConnectionProxy()

KDbConnectionProxy::~KDbConnectionProxy ( )
override

Deletes this proxy. Owned connection is closed and destroyed.

Definition at line 52 of file KDbConnectionProxy.cpp.

Member Function Documentation

◆ alterTable()

tristate KDbConnectionProxy::alterTable ( KDbTableSchema * tableSchema,
KDbTableSchema * newTableSchema )

Definition at line 466 of file KDbConnectionProxy.cpp.

◆ alterTableName()

bool KDbConnectionProxy::alterTableName ( KDbTableSchema * tableSchema,
const QString & newName,
AlterTableNameOptions options = AlterTableNameOption::Default )

Definition at line 471 of file KDbConnectionProxy.cpp.

◆ anyAvailableDatabaseName()

QString KDbConnectionProxy::anyAvailableDatabaseName ( )
overridevirtual
Returns
name of any (e.g. first found) database for this connection. This method does not close or open this connection. The method can be used (it is also internally used, e.g. for database dropping) when we need a database name before we can connect and execute any SQL statement (e.g. DROP DATABASE).

The method can return nul lstring, but in this situation no automatic (implicit) connections could be made, what is useful by e.g. dropDatabase().

Note for driver developers: return here a name of database which you are sure is existing. Default implementation returns:

See description of KDbDriverBehavior::ALWAYS_AVAILABLE_DATABASE_NAME member. You may want to reimplement this method only when you need to depend on this connection specifics (e.g. you need to check something remotely).

Reimplemented from KDbConnection.

◆ drv_alterTableName()

bool KDbConnectionProxy::drv_alterTableName ( KDbTableSchema * tableSchema,
const QString & newName )
overridevirtual

Alters table's described tableSchema name to newName. This is the default implementation, using "ALTER TABLE <oldname> RENAME TO <newname>", what's supported by SQLite >= 3.2, PostgreSQL, MySQL. Backends lacking ALTER TABLE, for example SQLite, reimplement this with by an inefficient data copying to a new table. In any case, renaming is performed at the backend. It's good idea to keep the operation within a transaction.

Returns
true on success.

◆ drv_beginTransaction()

KDbTransactionData * KDbConnectionProxy::drv_beginTransaction ( )
overridevirtual

Note for driver developers: begins new transaction and returns handle to it. Default implementation just executes "BEGIN" sql statement and returns just empty data (KDbTransactionData object). Ownership of the returned object is passed to the caller.

Drivers that do not support transactions (see KDbDriver::features()) do never call this method. Reimplement this method if you need to do something more (e.g. if you driver will support multiple transactions per connection). Make subclass of KDbTransactionData (declared in KDbTransaction.h) and return object of this subclass. nullptr should be returned on error. Do not check anything in connection (isConnected(), etc.) - all is already done.

Todo
Add support for nested transactions, e.g. KDbTransactionData* beginTransaction(KDbTransactionData *parent)

◆ drv_createTable() [1/2]

bool KDbConnectionProxy::drv_createTable ( const KDbTableSchema & tableSchema)
overridevirtual

Creates table using tableSchema information.

Returns
true on success.

Default implementation builds a statement using createTableStatement() and calls executeSql(). Note for driver developers: reimplement this only to perform creation in other way.

Reimplemented from KDbConnection.

Definition at line 605 of file KDbConnectionProxy.cpp.

◆ drv_createTable() [2/2]

bool KDbConnectionProxy::drv_createTable ( const QString & tableName)
overridevirtual

Creates table named by tableName. Schema object must be on schema tables' list before calling this method (otherwise false if returned). Just uses drv_createTable( const KDbTableSchema& tableSchema ). Used internally, e.g. in createDatabase().

Returns
true on success

Reimplemented from KDbConnection.

Definition at line 687 of file KDbConnectionProxy.cpp.

◆ drv_databaseExists()

bool KDbConnectionProxy::drv_databaseExists ( const QString & dbName,
bool ignoreErrors = true )
overridevirtual

For optional reimplementation: asks server if database dbName exists. This method is used internally in databaseExists(). The default implementation calls databaseNames and checks if that list contains dbName. If you need to ask the server specifically if a database exists, eg. if you can't retrieve a list of all available database names, please reimplement this method and do all needed checks.

See databaseExists() description for details about ignoreErrors argument. You should use it properly in your implementation.

Note: This method should also work if there is already database used (with useDatabase()); in this situation no changes should be made in current database selection.

Definition at line 682 of file KDbConnectionProxy.cpp.

◆ drv_dropTable()

Physically drops table named with name. Default impelmentation executes "DROP TABLE.." command, so you rarely want to change this.

Reimplemented from KDbConnection.

Definition at line 621 of file KDbConnectionProxy.cpp.

◆ drv_executeSql()

bool KDbConnectionProxy::drv_executeSql ( const KDbEscapedString & sql)
overridevirtual

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.

executeSql

Implements KDbConnection.

Definition at line 646 of file KDbConnectionProxy.cpp.

◆ drv_getDatabasesList()

bool KDbConnectionProxy::drv_getDatabasesList ( QStringList * list)
overridevirtual

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.

Definition at line 651 of file KDbConnectionProxy.cpp.

◆ drv_getServerVersion()

bool KDbConnectionProxy::drv_getServerVersion ( KDbServerVersionInfo * version)
overridevirtual

For implementation: Sets version to real server's version. Depending on backend type this method is called after (if KDbDriverBehavior::USING_DATABASE_REQUIRED_TO_CONNECT is true) or before database is used (if KDbDriverBehavior::USING_DATABASE_REQUIRED_TO_CONNECT is false), i.e. for PostgreSQL it is called after. In any case it is called after successful drv_connect().

Returns
true on success.

◆ drv_isDatabaseUsed()

bool KDbConnectionProxy::drv_isDatabaseUsed ( ) const
overridevirtual
Returns
true if internal driver's structure is still in opened/connected state and database is used. Note for driver developers: Put here every test that you can do using your internal engine's database API, eg (a bit schematic): my_connection_struct->isConnected()==true. Do not check things like KDbConnection::isDatabaseUsed() here or other things that "KDb already knows" at its level. If you cannot test anything, just leave default implementation (that returns true).

Result of this method is used as an additional chance to check for isDatabaseUsed(). Do not call this method from your driver's code, it should be used at KDb level only.

Reimplemented from KDbConnection.

Definition at line 677 of file KDbConnectionProxy.cpp.

◆ drv_prepareSql()

KDbSqlResult * KDbConnectionProxy::drv_prepareSql ( const KDbEscapedString & sql)
overridevirtual

Prepares query for a raw SQL statement sql with possibility of returning records.

It is useful mostly for SELECT queries. While INSERT queries do not return records, the KDbSqlResult object offers KDbSqlResult::lastInsertRecordId(). The @sql should be is valid and properly escaped. Only use this method if you really need. For low-level access to the results (without cursors). The result may be not stored (not buffered) yet. Use KDbSqlResult::fetchRecord() to fetch each record.

Returns
Null pointer if there is no proper result or error. Ownership of the returned object is passed to the caller.

drv_beginTransaction()

Reimplemented from KDbConnection.

Definition at line 702 of file KDbConnectionProxy.cpp.

◆ drv_setAutoCommit()

bool KDbConnectionProxy::drv_setAutoCommit ( bool on)
overridevirtual

Changes autocommiting option for established connection.

Returns
true on success.

Note for driver developers: reimplement this only if your engine allows to set special auto commit option (like "SET AUTOCOMMIT=.." in MySQL). If not, auto commit behavior will be simulated if at least single transactions per connection are supported by the engine. Do not set any internal flags for autocommiting – it is already done inside setAutoCommit().

Default implementation does nothing with connection, just returns true.

◆ drv_useDatabase()

bool KDbConnectionProxy::drv_useDatabase ( const QString & dbName = QString(),

overridevirtual

For implementation: opens existing database using connection

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

Implements KDbConnection.

Definition at line 666 of file KDbConnectionProxy.cpp.

◆ escapeIdentifier()

QString KDbConnectionProxy::escapeIdentifier ( const QString & id) const
overridevirtual

Identifier escaping function in the associated KDbDriver.

Calls the identifier escaping function in this connection to escape table and column names. This should be used when explicitly constructing SQL strings (e.g. "FROM " + escapeIdentifier(tablename)). It should not be used for other functions (e.g. don't do useDatabase(escapeIdentifier(database))), because the identifier will be escaped when the called function generates, for example, "USE " + escapeIdentifier(database).

For efficiency, KDb "system" tables (prefixed with kexi__) and columns therein are not escaped - we assume these are valid identifiers for all drivers.

Use KDbEscapedString::isValid() to check if escaping has been performed successfully. Invalid strings are set to null in addition, that is KDbEscapedString::isNull() is true, not just isEmpty().

Reimplemented from KDbConnection.

Definition at line 574 of file KDbConnectionProxy.cpp.

◆ escapeString()

KDbEscapedString KDbConnectionProxy::escapeString ( const QString & str) const
