Functions

func CheckIndicesCount

func CheckIndicesCount(ctx sessionctx.Context, dbName, tableName string, indices []string) (byte, int, error)

CheckIndicesCount compares indices count with table count. It returns the count greater type, the index offset and an error. It returns nil if the count from the index is equal to the count from the table columns, otherwise it returns an error and the corresponding index's offset.

func CheckRecordAndIndex

func CheckRecordAndIndex(ctx context.Context, sessCtx sessionctx.Context, txn kv.Transaction, t table.Table, idx table.Index) error

CheckRecordAndIndex is exported for testing.

Types

type RecordData

type RecordData struct {
	Handle kv.Handle
	Values []types.Datum
}

RecordData is the record data composed of a handle and values.
