Overview

common package contains functions from internal/db which need to be shared commonly with other packages that have a cyclic dependency on internal/db like internal/oplog.

Functions

func BuildUpdatePaths

func BuildUpdatePaths(fieldValues map[string]interface{}, fieldMask []string, allowZeroFields []string) (masks []string, nulls []string)

BuildUpdatePaths takes a map of field names to field values, field masks, fields allowed to be zero value, and returns both a list of field names to update and a list of field names that should be set to null.

func Intersection

func Intersection(av, bv []string) ([]string, map[string]string, map[string]string, error)

Intersection is a case-insensitive search for intersecting values. Returns []string of the Intersection with values in lowercase, and map[string]string of the original av and bv, with the key set to uppercase and value set to the original

func SqlOpen

func SqlOpen(driverName, dataSourceName string) (*sql.DB, error)

func UpdateFields

func UpdateFields(i interface{}, fieldMaskPaths []string, setToNullPaths []string) (map[string]interface{}, error)

UpdateFields will create a map[string]interface of the update values to be sent to the db. The map keys will be the field names for the fields to be updated. The caller provided fieldMaskPaths and setToNullPaths must not intersect. fieldMaskPaths and setToNullPaths cannot both be zero len.
