Types

type Column

type Column struct {
	// contains filtered or unexported fields
}

func NewColumn

func NewColumn(name string, columnType types.TypeID, hasIndex bool, indexKind index_constants.IndexKind, indexHeaderPageID types.PageID, expr interface{}) *Column

indexHeaderPageID should be types.PageID(-1) if there is no special reason the ID is set when CreateTable is called expr argument should be pointer of subtype of expression.Expression
