Member Function Documentation

static vtkPostgreSQLQuery* vtkPostgreSQLQuery::New ( )

static

void vtkPostgreSQLQuery::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 int vtkPostgreSQLQuery::IsTypeOf ( const char *  type )

static

virtual int vtkPostgreSQLQuery::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 vtkPostgreSQLQuery* vtkPostgreSQLQuery::SafeDownCast ( vtkObjectBase *  o )

static

virtual vtkObjectBase* vtkPostgreSQLQuery::NewInstanceInternal ( ) const

protectedvirtual

)

const

bool vtkPostgreSQLQuery::Execute ( )

virtual

Execute the query.

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

Implements vtkSQLQuery.

int vtkPostgreSQLQuery::GetNumberOfFields ( )

virtual

The number of fields in the query result.

Implements vtkRowQuery.

const char* vtkPostgreSQLQuery::GetFieldName ( int  i )

virtual

Return the name of the specified query field.

Implements vtkRowQuery.

int vtkPostgreSQLQuery::GetFieldType ( int  i )

virtual

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

Implements vtkRowQuery.

bool vtkPostgreSQLQuery::NextRow ( )

virtual

Advance row, return false if past end.

Implements vtkRowQuery.

bool vtkPostgreSQLQuery::HasError ( )

virtual

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

Implements vtkRowQuery.

bool vtkPostgreSQLQuery::BeginTransaction ( )

virtual

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

Reimplemented from vtkSQLQuery.

bool vtkPostgreSQLQuery::RollbackTransaction ( )

virtual

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

Reimplemented from vtkSQLQuery.

bool vtkPostgreSQLQuery::CommitTransaction ( )

virtual

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

Reimplemented from vtkSQLQuery.

vtkVariant vtkPostgreSQLQuery::DataValue ( vtkIdType  c )

virtual

Return data in current row, field c.

Implements vtkRowQuery.

const char* vtkPostgreSQLQuery::GetLastErrorText ( )

virtual

Get the last error text from the query.

Implements vtkRowQuery.

virtual vtkStdString vtkPostgreSQLQuery::EscapeString ( vtkStdString  s, bool  addSurroundingQuotes = true  )

virtual

Escape a string for inclusion into an SQL query.

Reimplemented from vtkSQLQuery.

int vtkPostgreSQLQuery::GetNumberOfRows

(

)

Unlike some databases, Postgres can tell you right away how many rows are in the results of your query.
