Structs

• CaseStatement
• CommonTableExpression
  A table definition inside a WITH clause (WithClause).
• Condition
  Represents the value of an Condition::any or Condition::all: a set of disjunctive or conjunctive conditions.
• ConditionHolder
• Cycle
  For recursive WithQuery WithClauses the CYCLE sql clause can be specified to avoid creating an infinite traversals that loops on graph cycles indefinitely. You specify an expression that identifies a node in the graph and that will be used to determine during the iteration of the execution of the query when appending of new values whether the new values are distinct new nodes or are already visited and therefore they should be added again into the result.
• DeleteStatement
  Delete existing rows from the table
• FrameClause
  Frame clause
• InsertStatement
  Insert any new rows into an existing table
• JoinExpr
  Join expression used in select statement
• LockClause
• OnConflict
• Query
  Shorthand for constructing any table query
• Returning
  Shorthand for constructing ReturningClause
• Search
  For recursive WithQuery WithClauses the traversing order can be specified in some databases that support this functionality.
• SelectExpr
  Select expression used in select statement
• SelectStatement
  Select rows from an existing table
• UpdateStatement
