static int vtkODBCQuery::IsTypeOf ( const char * type )

static

virtual int vtkODBCQuery::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 vtkSQLQuery.

void vtkODBCQuery::PrintSelf	(	ostream &	os,
		vtkIndent	indent
	)

virtual

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.

static vtkODBCQuery* vtkODBCQuery::New ( )

static

bool vtkODBCQuery::Execute ( )

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

virtual

The number of fields in the query result.

Implements vtkRowQuery.

const char* vtkODBCQuery::GetFieldName ( int i )

virtual

Return the name of the specified query field.

int vtkODBCQuery::GetFieldType ( int i )

virtual

Return the type of the field, using the constants defined in vtkType.h.

Implements vtkRowQuery.

bool vtkODBCQuery::NextRow ( )

virtual

Advance row, return false if past end.

Implements vtkRowQuery.

bool vtkODBCQuery::HasError ( )

virtual

Return true if there is an error on the current query.

vtkVariant vtkODBCQuery::DataValue ( vtkIdType c )

virtual

Return data in current row, field c.

virtual

Begin, commit, or roll back a transaction.

bool vtkODBCQuery::SetQuery ( const char * queryString )

virtual

Set the query string to be used.

Returns true if the query is OK; false if there's some problem with it that can be detected before execution.

Reimplemented from vtkSQLQuery.

const char* vtkODBCQuery::GetQuery ( )

virtual

Set the query string to be used.

Returns true if the query is OK; false if there's some problem with it that can be detected before execution.

Reimplemented from vtkSQLQuery.

bool vtkODBCQuery::BindParameter	(	int	index,
		unsigned char	value
	)

virtual

Bind a parameter to a placeholder in a query.

A full discussion of this feature is beyond the scope of this header file, but in short, here's how it works:

Instead of saying "SELECT foo FROM mytable WHERE myfield = 12345" you can say "SELECT foo FROM mytable WHERE myfield = ?". The ? character is a placeholder for a parameter that must then be bound. Call BindParameter(0, 12345) to bind the integer value 12345 to that field. Placeholders are indexed starting at 0.

You are responsible for making sure that the types match when you call BindParameter. You don't have to get it precisely correct: in general, the SQL driver is smart enough to do things like cast a short to a long or a float to a double.

Bound parameters were introduced in ANSI SQL 92. Please see that standard for more information.

Most of these methods are excluded from wrapping because the Java wrapper treats all integer types from char up through 64-bit long as 'int'. This is incorrect behavior but what else am I going to do?

Finally, the default implementation for BindParameter(int, vtkVariant) dispatches to one of the more type-specific versions. It should be OK to use in database drivers without modification.
