Detailed Description

maintain an ODBC connection to a SQL database

ODBC is a standard for connecting to an SQL database regardless of vendor or implementation. In order to make it work you need two separate pices of software: a driver manager and then a database-specific driver. On Windows, the driver manager is built into the OS. On Unix platforms, the open-source packages iODBC and unixODBC will do the job. Mac OS X has its own driver manager and can also use the open-source packages. Database-specific drivers must be obtained from the entity that makes the database(s) you use.

Unlike the other VTK database drivers, ODBC can read its parameters from a configuration file (odbc.ini). That file can define an entire set of connection parameters and give it a single name called a data source name (DSN). Writing and maintaining odbc.ini files is beyond the scope of this header file.

Warning
The password supplied as an argument to the Open call will override whatever password is set (if any) in the DSN definition. To use the password from the DSN definition, pass in nullptr for the password argument.
Also, vtkSQLDatabase::CreateFromURL() will only handle URLs of the following form for ODBC:
odbc://[user@]datsourcename[:port]/[dbname]
Anything more complicated than that needs to be set up manually.
Finally, this class does not yet support the schema API present in the SQLite, MySQL and PostgreSQL drivers. Those functions will be added once the bare-bones driver has been successfully integrated into VTK.

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.

◆ PrintSelf()

void vtkODBCDatabase::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 vtkODBCDatabase * vtkODBCDatabase::New ( )
static

◆ Open()

bool vtkODBCDatabase::Open ( const char *  password)
overridevirtual

Return whether the database has an open connection.

Implements vtkSQLDatabase.

vtkSQLQuery * vtkODBCDatabase::GetQueryInstance ( )
overridevirtual

Return an empty query on this database.

Implements vtkSQLDatabase.

◆ GetLastErrorText()

override

Return whether a feature is supported by the database.

◆ SetDataSourceName()

virtual void vtkODBCDatabase::SetDataSourceName ( const char *  )
virtual

Set the data source name.

For ODBC connections this will be something listed in odbc.ini. The location of that file varies wildly based on system, ODBC library, and installation. Good luck.

◆ GetDataSourceName()

virtual char * vtkODBCDatabase::GetDataSourceName ( )
virtual

Set the data source name.

For ODBC connections this will be something listed in odbc.ini. The location of that file varies wildly based on system, ODBC library, and installation. Good luck.

int  colHandle 
)
overridevirtual

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

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

Reimplemented from vtkSQLDatabase.

vtkStdString vtkODBCDatabase::GetIndexSpecification ( vtkSQLDatabaseSchema schema,
int  tblHandle,
int  idxHandle,
