QgsSQLStatement::NodeSelect class

SELECT node.

Base classes

NodeSelect(const QList<QgsSQLStatement::NodeTableDef*>& tableList, const QList<QgsSQLStatement::NodeSelectedColumn*>& columns, bool distinct): Constructor.

void accept(QgsSQLStatement::Visitor& v) const override: Support the visitor pattern.
void appendJoin(QgsSQLStatement::NodeJoin* join): Append a join.
auto clone() const -> QgsSQLStatement::Node* override: Generate a clone of this node.
auto columns() const -> QList<QgsSQLStatement::NodeSelectedColumn*>: Returns the list of columns.
auto distinct() const -> bool: Returns if the SELECT is DISTINCT.
auto dump() const -> QString override: Abstract virtual dump method.
auto joins() const -> QList<QgsSQLStatement::NodeJoin*>: Returns the list of joins.
auto nodeType() const -> QgsSQLStatement::NodeType override: Abstract virtual that returns the type of this node.
auto orderBy() const -> QList<QgsSQLStatement::NodeColumnSorted*>: Returns the list of order by columns.
void setJoins(const QList<QgsSQLStatement::NodeJoin*>& joins): Sets joins.
void setOrderBy(const QList<QgsSQLStatement::NodeColumnSorted*>& orderBy): Sets order by columns.
void setWhere(QgsSQLStatement::Node* where): Sets where clause.
auto tables() const -> QList<QgsSQLStatement::NodeTableDef*>: Returns the list of tables.
auto where() const -> QgsSQLStatement::Node*: Returns the where clause.

Support the visitor pattern.

Parameters
v	A visitor that visits this node.

For any implementation this should look like

C++:

v.visit( *this );

Python:

v.visit( self)

Generate a clone of this node.

Returns	a deep copy of this node.

Make sure that the clone does not contain any information which is generated in prepare and context related. Ownership is transferred to the caller.

Abstract virtual dump method.

Returns	A statement which represents this node as string

Abstract virtual that returns the type of this node.

Returns	The type of this node
