Functions ¶
func GetAllTables ¶ added in v0.0.6
func GetAllTables() []string
GetAllTables returns all registered table names
func InitMysqlByConfig ¶ added in v0.0.6
func InitMysqlByConfig() error
func InitPGByConfig ¶
func InitPGByConfig() error
func MapRowToStruct ¶ added in v0.0.6

func MustInitMysqlByConfig ¶ added in v0.0.6
func MustInitMysqlByConfig()
func MustInitPGByConfig ¶
func MustInitPGByConfig()
func RegisterDeleteCallback ¶ added in v0.0.6
func RegisterDeleteCallback(tableName string, cb DeleteCallback)
RegisterDeleteCallback registers a delete callback for a specific table
func RegisterInsertCallback ¶ added in v0.0.6
func RegisterInsertCallback(tableName string, cb InsertCallback)
RegisterInsertCallback registers an insert callback for a specific table
func RegisterUpdateCallback ¶ added in v0.0.6
func RegisterUpdateCallback(tableName string, cb UpdateCallback)
RegisterUpdateCallback registers an update callback for a specific table
