void vtkQtSQLQuery::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.

◆ Execute()

bool vtkQtSQLQuery::Execute ( )

Execute the query.

This must be performed before any field name or data access functions are used.

Implements vtkSQLQuery.

◆ GetNumberOfFields()

int vtkQtSQLQuery::GetNumberOfFields ( )
overridevirtual

The number of fields in the query result.

Implements vtkRowQuery.

overridevirtual

Return the type of the specified query field, as defined in vtkType.h.

Implements vtkRowQuery.

◆ NextRow()

bool vtkQtSQLQuery::NextRow ( )
overridevirtual

Advance row, return false if past end.

Implements vtkRowQuery.

◆ DataValue()

vtkVariant vtkQtSQLQuery::DataValue ( vtkIdType  c)
overridevirtual

Return data in current row, field c.

Implements vtkRowQuery.

◆ HasError()
