Overview ¶
Package groveset lists the columns a grove model-based UPDATE writes, with their values. A store uses it to build that SET by hand when one column has to take an expression, such as version = version + 1, which a model-based UPDATE cannot express and which explicit Set calls replace wholesale.

Types ¶
type Column ¶
Column is one column of the SET and the value it is set to.
func Columns ¶
Columns returns the columns a model-based UPDATE of model would set, in field order, leaving out any named in skip. It picks fields the way the grove drivers do: every mapped field except the primary key, scanonly and autoincrement fields. Values are passed as the fields hold them, which is also what the drivers bind for a field without nullzero.
