Functions

func CheckColumnType 

func CheckColumnType(col ColumnDescriptor, typ parser.Type, pmap *parser.PlaceholderInfo) error

CheckColumnType verifies that a given value is compatible with the type requested by the column. If the value is a placeholder, the type of the placeholder gets populated.

func CheckValueWidth 

func CheckValueWidth(col ColumnDescriptor, val parser.Datum) error

CheckValueWidth checks that the width (for strings, byte arrays, and bit string) and scale (for decimals) of the value fits the specified column type. Used by INSERT and UPDATE.

func ColumnsSelectors 

func ColumnsSelectors(cols []ColumnDescriptor) parser.SelectExprs

ColumnsSelectors generates Select expressions for cols.

func DTupleToEncDatumRow 

func DTupleToEncDatumRow(row EncDatumRow, types []ColumnType, tuple parser.DTuple)

DTupleToEncDatumRow converts a parser.DTuple to an EncDatumRow.

func DecodeIndexKey 

func DecodeIndexKey(
	a *DatumAlloc,
	desc *TableDescriptor,
	indexID IndexID,
	vals []EncDatum,
	colDirs []encoding.Direction,
	key []byte,
) ([]byte, bool, error)

DecodeIndexKey decodes the values that are a part of the specified index key. ValTypes is a slice returned from makeKeyVals. The remaining bytes in the index key are returned which will either be an encoded column ID for the primary key index, the primary key suffix for non-unique secondary indexes or unique secondary indexes containing NULL or empty. If the given descriptor does not match the key, false is returned with no error.

func DecodeKeyVals 

func DecodeKeyVals(
	a *DatumAlloc, vals []EncDatum, directions []encoding.Direction, key []byte,
) ([]byte, error)

DecodeKeyVals decodes the values that are part of the key. The decoded values are stored in the vals. If this slice is nil, the direction used will default to encoding.Ascending.

func DecodeTableIDIndexID 

func DecodeTableIDIndexID(key []byte) ([]byte, ID, IndexID, error)

DecodeTableIDIndexID decodes a table id followed by an index id.

func DecodeTableKey 

func DecodeTableKey(
	a *DatumAlloc, valType parser.Type, key []byte, dir encoding.Direction,
) (parser.Datum, []byte, error)

DecodeTableKey decodes a table key/value.

func DecodeTableValue 

func DecodeTableValue(a *DatumAlloc, valType parser.Type, b []byte) (parser.Datum, []byte, error)

DecodeTableValue decodes a value encoded by EncodeTableValue.

func EncDatumRowToDTuple 

func EncDatumRowToDTuple(tuple parser.DTuple, row EncDatumRow, da *DatumAlloc) error

EncDatumRowToDTuple converts a given EncDatumRow to a DTuple.

func EncodeColumns 

func EncodeColumns(
	columnIDs []ColumnID,
	directions directions,
	colMap map[ColumnID]int,
	values []parser.Datum,
	keyPrefix []byte,
) (key []byte, containsNull bool, err error)

EncodeColumns is a version of EncodeIndexKey that takes ColumnIDs and directions explicitly.

func EncodeDTuple 

func EncodeDTuple(b []byte, d parser.DTuple) ([]byte, error)

EncodeDTuple encodes a DTuple (order-preserving).

func EncodeDatum 

func EncodeDatum(b []byte, d parser.Datum) ([]byte, error)

EncodeDatum encodes a datum (order-preserving encoding, suitable for keys).

func EncodeIndexKey 

func EncodeIndexKey(
	tableDesc *TableDescriptor,
	index *IndexDescriptor,
	colMap map[ColumnID]int,
	values []parser.Datum,
	keyPrefix []byte,
) (key []byte, containsNull bool, err error)

EncodeIndexKey creates a key by concatenating keyPrefix with the encodings of the columns in the index.

If a table or index is interleaved, `encoding.encodedNullDesc` is used in place of the family id (a varint) to signal the next component of the key. An example of one level of interleaving (a parent): /<parent_table_id>/<parent_index_id>/<field_1>/<field_2>/NullDesc/<table_id>/<index_id>/<field_3>/<family>

Returns the key and whether any of the encoded values were NULLs.

Note that ImplicitColumnIDs are not encoded, so the result isn't always a full index key.

func EncodeSecondaryIndexes 

func EncodeSecondaryIndexes(
	tableDesc *TableDescriptor,
	indexes []IndexDescriptor,
	colMap map[ColumnID]int,
	values []parser.Datum,
	secondaryIndexEntries []IndexEntry,
) error

EncodeSecondaryIndexes encodes key/values for the secondary indexes. colMap maps ColumnIDs to indices in `values`. secondaryIndexEntries is the return value (passed as a parameter so the caller can reuse between rows) and is expected to be the same length as indexes.

func EncodeTableKey 

func EncodeTableKey(b []byte, val parser.Datum, dir encoding.Direction) ([]byte, error)

EncodeTableKey encodes `val` into `b` and returns the new buffer.

func EncodeTableValue 

func EncodeTableValue(appendTo []byte, colID ColumnID, val parser.Datum) ([]byte, error)

EncodeTableValue encodes `val` into `appendTo` using DatumEncoding_VALUE and returns the new buffer.

func ExtractIndexKey 

func ExtractIndexKey(
	a *DatumAlloc, tableDesc *TableDescriptor, entry client.KeyValue,
) (roachpb.Key, error)

ExtractIndexKey constructs the index (primary) key for a row from any index key/value entry, including secondary indexes.

Don't use this function in the scan "hot path".

func IsIntegrityConstraintError 

func IsIntegrityConstraintError(err error) bool

IsIntegrityConstraintError returns true if the error is some kind of SQL constraint violation.

func IsSystemConfigID 

func IsSystemConfigID(id ID) bool

IsSystemConfigID returns true if this ID is for a system config object.

func MakeAllDescsMetadataKey 

func MakeAllDescsMetadataKey() roachpb.Key

MakeAllDescsMetadataKey returns the key for all descriptors.

func MakeColumnDefDescs 

func MakeColumnDefDescs(
	d *parser.ColumnTableDef, searchPath parser.SearchPath,
) (*ColumnDescriptor, *IndexDescriptor, error)

MakeColumnDefDescs creates the column descriptor for a column, as well as the index descriptor if the column is a primary key or unique. The search path is used for name resolution for DEFAULT expressions.

func MakeDescMetadataKey 

func MakeDescMetadataKey(descID ID) roachpb.Key

MakeDescMetadataKey returns the key for the descriptor.

func MakeIndexKeyPrefix 

func MakeIndexKeyPrefix(desc *TableDescriptor, indexID IndexID) []byte

MakeIndexKeyPrefix returns the key prefix used for the index's data.

func MakeKeyFromEncDatums 

func MakeKeyFromEncDatums(
	values EncDatumRow,
	tableDesc *TableDescriptor,
	index *IndexDescriptor,

	alloc *DatumAlloc,
) (roachpb.Key, error)

MakeKeyFromEncDatums creates a key by concatenating keyPrefix with the encodings of the given EncDatum values. The values correspond to index.ColumnIDs.

If a table or index is interleaved, `encoding.encodedNullDesc` is used in place of the family id (a varint) to signal the next component of the key. An example of one level of interleaving (a parent): /<parent_table_id>/<parent_index_id>/<field_1>/<field_2>/NullDesc/<table_id>/<index_id>/<field_3>/<family>

Note that ImplicitColumnIDs are not encoded, so the result isn't always a full index key.

-1 if the receiver comes before the rhs in the ordering,
+1 if the receiver comes after the rhs in the ordering,
0 if the relative order does not matter (i.e. the two rows have the same
  values for the columns in the ordering).

Note that a return value of 0 does not (in general) imply that the rows are equal; for example, rows [1 1 5] and [1 1 6] when compared against ordering {{0, asc}, {1, asc}} (i.e. ordered by first column and then by second column).

type TableDescriptor struct {

	// ID of the parent database.
	ParentID ID `protobuf:"varint,4,opt,name=parent_id,json=parentId,casttype=ID" json:"parent_id"`
	// Monotonically increasing version of the table descriptor.
	//
	// Invariants:
	// 1. not more than two subsequent versions of the table
	// descriptor can be leased. This is to make the system
	// easy to reason about, by permiting mutation state
	// changes (reflected in the next version), only when the existing
	// state (reflected in the current version) is present on all
	// outstanding unexpired leases.
	// 2. A schema change command (ALTER, RENAME, etc) never directly
	// increments the version. This allows the command to execute without
	// waiting for the entire cluster to converge to a single version
	// preventing weird deadlock situations. For instance, a transaction
	// with a schema change command might use a descriptor lease that is
	// at version: v - 1, and therefore deadlock when it tries to wait
	// for version: v, in the process of incrementing it to v + 1.
	// Therefore, a schema change command never increments the version,
	// and instead, sets the up_version boolean to notify the schema
	// changer execution engine that runs a future transaction to
	// increment the version.
	//
	// The schema change commands must therefore make *safe* modifications
	// to the table descriptor, such as scheduling long running schema
	// changes through mutations for future execution, or making simple
	// schema changes like RENAME that only modify the table descriptor in a
	// single transaction.
	//
	// Multiple schema changes in the same transaction set up_version.
	// The actual schema change execution that follows a schema change
	// command sees the up_version boolean set, and increments the
	// table version after ensuring that there are no unexpired leases
	// for version - 1. The schema change execution must increment
	// the version before executing future state changes, to ensure
	// that the scheduled mutations made by the original commands are
	// visible on all leases. Multiple schema change mutations can be
	// grouped together on a particular version increment.
	//
	// If schema change commands are safe to run without incrementing
	// the version, why do it later on? We increment the version
	// to ensure that all the nodes renew their leases with the new version
	// and get to see what the schema change command has done quickly.

}

The schema update lease. A single goroutine across a cockroach cluster can own it, and will execute pending schema changes for this table. Since the execution of a pending schema change is through transactions, it is legal for more than one goroutine to attempt to execute it. This lease reduces write contention on the schema change.
