type TableFunctionRowIter added in v0.18.0 

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

func (*TableFunctionRowIter) Close added in v0.18.0 

func (i *TableFunctionRowIter) Close(_ *sql.Context) error

func (*TableFunctionRowIter) Next added in v0.18.0 

func (i *TableFunctionRowIter) Next(_ *sql.Context) (sql.Row, error)

type TableRevision added in v0.18.0 

type TableRevision struct {
	*Table
}

TableRevision is a container for memory tables to run basic smoke tests for versioned queries. It overrides only enough of the Table interface required to pass those tests. Memory tables have a flag to force them to ignore session data and use embedded data, which is required for the versioned table tests to pass.

func NewPartitionedTableRevision added in v0.18.0 

func NewPartitionedTableRevision(db *BaseDatabase, name string, schema sql.PrimaryKeySchema, fkColl *ForeignKeyCollection, numPartitions int) *TableRevision

NewPartitionedTable creates a new Table with the given name, schema and number of partitions. Assigns the default collation, therefore if a different collation is desired, please use NewPartitionedTableWithCollation.

func (*TableRevision) AddColumn added in v0.18.0 

func (t *TableRevision) AddColumn(ctx *sql.Context, column *sql.Column, order *sql.ColumnOrder) error

func (*TableRevision) IgnoreSessionData added in v0.18.0 

func (t *TableRevision) IgnoreSessionData() bool

func (*TableRevision) Inserter added in v0.18.0

type TestIndexDriver 

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

TestIndexDriver is a non-performant index driver meant to aid in verification of engine correctness. It can not create or delete indexes, but will use the index types defined in this package to alter how queries are executed, retrieving values from the indexes rather than from the tables directly.

func NewIndexDriver 

func NewIndexDriver(db string, indexes map[string][]sql.DriverIndex) *TestIndexDriver

NewIndexDriver returns a new index driver for database and the indexes given, keyed by the table name.
