Detailed Description

vtkSQLQuery implementation for SQLite databases

This is an implementation of vtkSQLQuery for SQLite databases. See the documentation for vtkSQLQuery for information about what the methods do.

Bug:: Sometimes Execute() will return false (meaning an error) but GetLastErrorText() winds up null. I am not certain why this is happening.

Thanks:: Thanks to Andrew Wilson from Sandia National Laboratories for implementing this class.

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

static

virtual int vtkSQLiteQuery::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.

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

static

virtual vtkObjectBase* vtkSQLiteQuery::NewInstanceInternal ( ) const

protectedvirtual

vtkSQLiteQuery* vtkSQLiteQuery::NewInstance ( ) const

void vtkSQLiteQuery::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 vtkRowQuery.

static vtkSQLiteQuery* vtkSQLiteQuery::New ( )

static

bool vtkSQLiteQuery::SetQuery ( const char * query )

virtual

Set the SQL query string.

This must be performed before Execute() or BindParameter() can be called.

Reimplemented from vtkSQLQuery.

bool vtkSQLiteQuery::Execute ( )

virtual

Execute the query.

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

Implements vtkSQLQuery.

int vtkSQLiteQuery::GetNumberOfFields ( )

virtual

The number of fields in the query result.

Implements vtkRowQuery.

const char* vtkSQLiteQuery::GetFieldName ( int i )

virtual

Return the name of the specified query field.

Implements vtkRowQuery.

int vtkSQLiteQuery::GetFieldType ( int i )

virtual

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

Implements vtkRowQuery.

bool vtkSQLiteQuery::NextRow ( )

virtual

Advance row, return false if past end.

Implements vtkRowQuery.

bool vtkSQLiteQuery::HasError ( )

virtual

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

Implements vtkRowQuery.

bool vtkSQLiteQuery::BeginTransaction ( )

virtual

Begin, abort (roll back), or commit a transaction.

bool vtkSQLiteQuery::RollbackTransaction ( )

virtual

Begin, abort (roll back), or commit a transaction.

bool vtkSQLiteQuery::CommitTransaction ( )

virtual

Reimplemented from vtkSQLQuery.

vtkVariant vtkSQLiteQuery::DataValue ( vtkIdType c )

virtual

Return data in current row, field c.

Implements vtkRowQuery.

const char* vtkSQLiteQuery::GetLastErrorText ( )

virtual

Get the last error text from the query.

Implements vtkRowQuery.

bool vtkSQLiteQuery::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.
