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.

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.

		int	tblHandle,
		int	idxHandle,

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 )
