Functions

func ApplyBindings 

func ApplyBindings(n sql.Node, bindings map[string]sql.Expression) (sql.Node, map[string]bool, error)

ApplyBindings replaces all `BindVar` expressions in the given sql.Node with their corresponding sql.Expression entries in the provided |bindings| map. If a binding for a |BindVar| expression is not found in the map, no error is returned and the |BindVar| expression is left in place. There is no check on whether all entries in |bindings| are used at least once throughout the |n| but a map of all the used |bindings| are returned. sql.DeferredType instances will be resolved by the binding types.

func FindForeignKeyColMapping 

func FindForeignKeyColMapping(
	ctx *sql.Context,
	fkName string,
	localTbl sql.ForeignKeyTable,
	localFKCols []string,
	destFKCols []string,
	index sql.Index,
) ([]int, []sql.Type, error)

FindForeignKeyColMapping returns the mapping from a given row to its equivalent index position, based on the matching foreign key columns. This also verifies that the column types match, as it is a prerequisite for mapping. For foreign keys that do not match the full index, also returns the types to append during the key mapping, as all index columns must have a column expression. All strings are case-insensitive.

func FindIndexWithPrefix 

func FindIndexWithPrefix(ctx *sql.Context, tbl sql.IndexAddressableTable, prefixCols []string, ignoredIndexes ...string) (sql.Index, bool, error)

FindIndexWithPrefix returns an index that has the given columns as a prefix. The returned index is deterministic and follows the given rules, from the highest priority in descending order:

1. Columns exactly match the index 2. Columns match as much of the index prefix as possible 3. Unique index before non-unique 4. Largest index by column count 5. Index ID in ascending order

The prefix columns may be in any order, and the returned index will contain all of the prefix columns within its prefix. For example, the slices [col1, col2] and [col2, col1] will match the same index, as their ordering does not matter. The index [col1, col2, col3] would match, but the index [col1, col3] would not match as it is missing "col2". Prefix columns are case-insensitive.

func GetColumnFromIndexExpr 

func GetColumnFromIndexExpr(expr string, table sql.Table) *sql.Column

GetColumnFromIndexExpr returns column from the table given using the expression string given, in the form "table.column". Returns nil if the expression doesn't represent a column.

func GetColumnsAndPrepareExpressions 

func GetColumnsAndPrepareExpressions(
	ctx *sql.Context,
	exprs []sql.Expression,
) ([]string, []sql.Expression, error)

GetDatabaseCollation returns a database's collation. Also handles when a database does not explicitly support collations.

func GetDatabaseName 

func GetDatabaseName(nodeToSearch sql.Node) string

GetDatabaseName attempts to fetch the database name from the node. If not found directly on the node, searches the children. Returns the first database name found, regardless of whether there are more, therefore this is only intended to be used in situations where only a single database is expected to be found. Unlike how tables are handled in most nodes, databases may be stored as a string field therefore there will be situations where a database name exists on a node, but cannot be found through inspection.

func GetDeletable 

func GetDeletable(node sql.Node) (sql.DeletableTable, error)

func GetIndexLookup 

func GetIndexLookup(ita *IndexedTableAccess) sql.IndexLookup

func NewIndexedInSubqueryFilter 

func NewIndexedInSubqueryFilter(subquery *Subquery, child sql.Node, padding int, filterField *expression.GetField, equals bool) sql.Node

NewIndexedInSubqueryFilter returns an IndexedInSubqueryFilter sql.Node. The Node implements the semantics of `Filter(field IN (SELECT ...), Child)`, but runs the subquery `SELECT` first, and the makes repeated calls to `child.RowIter()` to get the matching Child rows. Typically `child` should be an `IndexedTableAccess`, and for this to be the right tradeoff, the results from `subquery` should be much smaller than the unfiltered results from `child`. `padding` is the number of `null` columns which will be appended to an incoming `Row` in the `RowIter` call because calling `Eval` on the `Subquery`, since the `Subquery` was originally expecting to expect within the scope of something like `child`. `child` itself should expect `RowIter()` calls with a single column `Row`, which will be the results from the `Subquery`. `filterField` is a `GetField` expression which will extract the field from `child` results that should be matched against the `subquery` results; this condition is still checked here because `child` is allowed to return non-matching rows. `equals` true means this node will call `subquery.Eval` and expect a single result, whereas `equals` false means this node will call `subquery.EvalMultiple` and expect 0 or more results.

func NewJSONTable 

func NewJSONTable(ctx *sql.Context, dataExpr sql.Expression, path string, colPaths []string, alias string, schema sql.PrimaryKeySchema) (sql.Node, error)

func NewStripRowNode 

func NewStripRowNode(child sql.Node, numCols int) sql.Node

func NewTableEditorIter 

func NewTableEditorIter(wrappedIter sql.RowIter, openerClosers ...sql.EditOpenerCloser) sql.RowIter

NewTableEditorIter returns a new *tableEditorIter by wrapping the given iterator. If the "statement_boundaries" session variable is set to false, then the original iterator is returned. Each of the |openerClosers| specified will be called to begin, complete, and discard statements as needed as the |wrappedIter| is processed.

func NillaryWithChildren 

func NillaryWithChildren(node sql.Node, children ...sql.Node) (sql.Node, error)

	RepresentingNode() sql.Node
	// Schema returns the schema of this RowIter.
	Schema() sql.Schema
}

BlockRowIter is an iterator that produces rows. It is an extended interface over RowIter. This is primarily used by block statements. In order to track the schema of a sql.RowIter from nested blocks, this extended row iter returns the relevant information inside of the iter itself. In addition, the most specific top-level Node for that iter is returned, as stored procedures use that Node to determine whether the iter represents a SELECT statement.

type CachedResults 

type CachedResults struct {
	UnaryNode
	// contains filtered or unexported fields
}

CachedResults tees the child node iterator into an in-memory cache for faster subsequent retrieval. This is usually combined with a HashLookup, whose RowIter defers to a CachedResult child to populate rows in memory on a first iteration. The second RowIter moves the rows from the memory cache to a hash map attached to HashLookup, disposing the CachedResult afterwards.

In the special case where we fill a CachedResult on pass one, but pass two never happens, we have to take care not to orphan the cache.

When we exhaust the source, but the cache is empty, subsequent calls to RowIter return an ErrEmptyCachedResult error for short-circuiting join trees.

When the memory manager cannot accommodate expanding the cache, we fall back to a passthrough iterator.

func NewCachedResults 

func NewCachedResults(n sql.Node) *CachedResults

NewCachedResults returns a cached results plan Node, which will use a RowCache to cache results generated by Child.RowIter() and return those results for future calls to RowIter.

type ChildParentMapping 

type ChildParentMapping []int

ChildParentMapping is a mapping from the foreign key columns of a child schema to the parent schema. The position in the slice corresponds to the position in the child schema, while the value at a given position refers to the position in the parent schema. For all columns that are not in the foreign key definition, a value of -1 is returned.

Here's an example: parent Schema: x1, x2, x3, x4, x5 child Schema: y1, y2, y3, y4 FOREIGN KEY (y2) REFERENCES parent (x4)

The slice for the above would be [-1, 3, -1, -1]. The foreign key uses the column "y2" on the child, which is the second position in the schema (and therefore the second position in the mapping). The equivalent parent column is "x4", which is in the fourth position (so 3 with zero-based indexed).

type LookupBuilder 

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

LookupBuilder abstracts secondary table access for an LookupJoin. A row from the primary table is first evaluated on the secondary index's expressions (columns) to produce a lookupBuilderKey. Consider the query below, assuming B has an index `xy (x,y)`:

select * from A join B on a.x = b.x AND a.y = b.y

Assume we choose A as the primary row source and B as a secondary lookup on `xy`. For every row in A, we will produce a lookupBuilderKey on B using the join condition. For the A row (x=1,y=2), the lookup key into B will be (1,2) to reflect the B-xy index access.

Then we construct a sql.RangeCollection to represent the (1,2) point lookup into B-xy. The collection will always be a single range, because a point lookup cannot be a disjoint set of ranges. The range will also have the same dimension as the index itself. If the join condition is a partial prefix on the index (ex: INDEX x (x)), the unfiltered columns are padded.

The <=> filter is a special case for two reasons. 1) It is not a point lookup, the corresponding range will either be IsNull or IsNotNull depending on whether the primary row key column is nil or not, respectfully. 2) The format of the output range is variable, while equality ranges are identical except for bound values.

Currently the analyzer constructs one of these and uses it for the IndexedTableAccess nodes below an indexed join, for example. This struct is also used to implement Expressioner on the IndexedTableAccess node.

type RecursiveCte 

type RecursiveCte struct {

	// Columns used to name lazily-loaded schema fields
	Columns []string
	// contains filtered or unexported fields
}

RecursiveCte is defined by two subqueries connected with a union: 

ex => WITH RECURSIVE [name]([Columns]) as ([Init] UNION [Rec]) ...

[Init] is a non-recursive select statement, and [Rec] selects from the recursive relation [name] until exhaustion. Note that if [Rec] is not recursive, the optimizer will fold the RecursiveCte into a SubqueryAlias.

The node is executed as follows:

  1. First, iterate the [Init] subquery.
  2. Collect the outputs of [Init] in a [temporary] buffer.
  3. When the iterator is exhausted, populate the recursive [working] table with the [temporary] buffer.
  4. Iterate [Rec], collecting outputs in the [temporary] buffer.
  5. Repeat steps (3) and (4) until [temporary] is empty.

A RecursiveCte, its [Init], and its [Rec] have the same projection count and types. [Init] will be resolved before [Rec] or RecursiveCte to share schema types.
