Detailed Description

maintain a connection to a MySQL database

This class provides a VTK interface to MySQL (http://www.mysql.com). Unlike file-based databases like SQLite, you talk to MySQL through a client/server connection. You must specify the hostname, (optional) port to connect to, username, password and database name in order to connect.

static vtkTypeBool vtkMySQLDatabase::IsTypeOf ( const char *  type)
static

◆ IsA()

virtual vtkTypeBool vtkMySQLDatabase::IsA ( const char *  name)
virtual

Return 1 if this class is the same type of (or a subclass of) the named class.

Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkSQLDatabase.

◆ SafeDownCast()

static vtkMySQLDatabase* vtkMySQLDatabase::SafeDownCast ( vtkObjectBase o)
static

◆ NewInstanceInternal()

virtual vtkObjectBase* vtkMySQLDatabase::NewInstanceInternal ( ) const
protectedvirtual

Reimplemented from vtkSQLDatabase.

◆ NewInstance()

vtkMySQLDatabase* vtkMySQLDatabase::NewInstance ( ) const

◆ PrintSelf()

void vtkMySQLDatabase::PrintSelf ( ostream &  os,
vtkIndent  indent 
)
overridevirtual

Methods invoked by print to print information about the object including superclasses.

Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkObject.

◆ New()

static vtkMySQLDatabase* vtkMySQLDatabase::New ( )
static

◆ Open()

bool vtkMySQLDatabase::Open ( const char *  password = 0)
overridevirtual

Open a new connection to the database.

You need to set the filename before calling this function. Returns true if the database was opened successfully; false otherwise.

Implements vtkSQLDatabase.

◆ Close()

void vtkMySQLDatabase::Close ( )
overridevirtual

Close the connection to the database.

Implements vtkSQLDatabase.

◆ IsOpen()

bool vtkMySQLDatabase::IsOpen ( )
overridevirtual

Return whether the database has an open connection.

Implements vtkSQLDatabase.

◆ GetQueryInstance()

vtkSQLQuery* vtkMySQLDatabase::GetQueryInstance ( )
overridevirtual

Return an empty query on this database.

Implements vtkSQLDatabase.

◆ GetTables()

vtkStringArray* vtkMySQLDatabase::GetTables ( )
overridevirtual

Get the list of tables from the database.

Implements vtkSQLDatabase.

◆ GetRecord()

vtkStringArray* vtkMySQLDatabase::GetRecord ( const char *  table)
overridevirtual

Get the list of fields for a particular table.

Implements vtkSQLDatabase.

◆ IsSupported()

bool vtkMySQLDatabase::IsSupported ( int  feature)
override

Return whether a feature is supported by the database.

◆ HasError()

bool vtkMySQLDatabase::HasError ( )
overridevirtual

Did the last operation generate an error.

Implements vtkSQLDatabase.

◆ GetLastErrorText()

const char* vtkMySQLDatabase::GetLastErrorText ( )
overridevirtual

Get the last error text from the database.

Implements vtkSQLDatabase.

◆ GetDatabaseType()

const char* vtkMySQLDatabase::GetDatabaseType ( )
inlineoverridevirtual

String representing database type (e.g.

"mysql").

Implements vtkSQLDatabase.

Definition at line 111 of file vtkMySQLDatabase.h.

◆ SetHostName()

virtual void vtkMySQLDatabase::SetHostName ( const char *  )
virtual

The database server host name.

◆ GetHostName()

virtual char* vtkMySQLDatabase::GetHostName ( )
virtual

◆ SetUser()

virtual void vtkMySQLDatabase::SetUser ( const char *  )
virtual

The user name for connecting to the database server.

◆ GetUser()

virtual char* vtkMySQLDatabase::GetUser ( )
virtual

◆ SetPassword()

virtual void vtkMySQLDatabase::SetPassword ( const char *  )
virtual

The user's password for connecting to the database server.

◆ SetDatabaseName()

virtual void vtkMySQLDatabase::SetDatabaseName ( const char *  )
virtual

The name of the database to connect to.

◆ GetDatabaseName()

virtual char* vtkMySQLDatabase::GetDatabaseName ( )
virtual

◆ SetReconnect()

virtual void vtkMySQLDatabase::SetReconnect ( int  )
virtual

Should automatic reconnection be enabled? This defaults to true.

If you change its value, you must do so before any call to Open().

◆ GetReconnect()

virtual int vtkMySQLDatabase::GetReconnect ( )
virtual

◆ ReconnectOn()

virtual void vtkMySQLDatabase::ReconnectOn ( )
virtual

◆ ReconnectOff()

virtual void vtkMySQLDatabase::ReconnectOff ( )
virtual

◆ SetServerPort()

virtual void vtkMySQLDatabase::SetServerPort ( int  )
virtual

The port used for connecting to the database.

◆ GetServerPort()

virtual int vtkMySQLDatabase::GetServerPort ( )
virtual

◆ GetURL()

vtkStdString vtkMySQLDatabase::GetURL ( )
overridevirtual

Get the URL of the database.

Implements vtkSQLDatabase.

◆ GetTablePreamble()

vtkStdString vtkMySQLDatabase::GetTablePreamble ( bool  b)
inlineoverridevirtual

Return the SQL string with the syntax of the preamble following a "CREATE TABLE" SQL statement.

NB: this method implements the MySQL-specific IF NOT EXISTS syntax, used when b = false.

Reimplemented from vtkSQLDatabase.

Definition at line 178 of file vtkMySQLDatabase.h.

◆ GetColumnSpecification()

vtkStdString vtkMySQLDatabase::GetColumnSpecification ( vtkSQLDatabaseSchema schema,
int  tblHandle,
int  colHandle 
)
overridevirtual

Return the SQL string with the syntax to create a column inside a "CREATE TABLE" SQL statement.

NB1: this method implements the MySQL-specific syntax:

* `<column name>` <column type> <column attributes>
* 

NB2: if a column has type SERIAL in the schema, this will be turned into INT NOT nullptr AUTO_INCREMENT. Therefore, one should not pass NOT nullptr as an attribute of a column whose type is SERIAL.

Reimplemented from vtkSQLDatabase.

◆ GetIndexSpecification()

vtkStdString vtkMySQLDatabase::GetIndexSpecification ( vtkSQLDatabaseSchema schema,
int  tblHandle,
int  idxHandle,
bool &  skipped 
)
overridevirtual

Return the SQL string with the syntax to create an index inside a "CREATE TABLE" SQL statement.

NB1: this method implements the MySQL-specific syntax:

* <index type> [<index name>]  (`<column name 1>`,... )
* 

NB2: since MySQL supports INDEX creation within a CREATE TABLE statement, skipped is always returned false.

Reimplemented from vtkSQLDatabase.

◆ CreateDatabase()

bool vtkMySQLDatabase::CreateDatabase ( const char *  dbName,
bool  dropExisting 
)

Create a new database, optionally dropping any existing database of the same name.

Returns true when the database is properly created and false on failure.

◆ DropDatabase()

bool vtkMySQLDatabase::DropDatabase ( const char *  dbName)

Drop a database if it exists.

Returns true on success and false on failure.

◆ ParseURL()

bool vtkMySQLDatabase::ParseURL ( const char *  url)
overridevirtual

Overridden to determine connection parameters given the URL.

This is called by CreateFromURL() to initialize the instance. Look at CreateFromURL() for details about the URL format.

Implements vtkSQLDatabase.
