Functions

func ApplyBindings 

func ApplyBindings(ctx *sql.Context, n sql.Node, bindings map[string]sql.Expression) (sql.Node, 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|.

This applies binding substitutions across *SubqueryAlias nodes, but will fail to apply bindings across other |sql.Opaque| nodes.

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)

GetColumnsAndPrepareExpressions extracts the unique columns required by all those expressions and fixes the indexes of the GetFields in the expressions to match a row with only the returned columns in that same order.

func GetInsertable 

func GetInsertable(node sql.Node) (sql.InsertableTable, error)

func GetTruncatable 

func GetTruncatable(node sql.Node) (sql.TruncateableTable, error)

func Inspect 

func Inspect(node sql.Node, f func(sql.Node) bool)

Inspect traverses the plan in depth-first order: It starts by calling f(node); node must not be nil. If f returns true, Inspect invokes f recursively for each of the children of node, followed by a call of f(nil).

func InspectExpressions 

func InspectExpressions(node sql.Node, f func(sql.Expression) bool)

InspectExpressions traverses the plan and calls sql.Inspect on any expression it finds.

func InspectExpressionsWithNode 

func InspectExpressionsWithNode(node sql.Node, f func(sql.Node, sql.Expression) bool)

InspectExpressionsWithNode traverses the plan and calls sql.Inspect on any expression it finds.

func IsBinary 

func IsBinary(node sql.Node) bool

IsBinary returns whether the node is binary or not.

func IsDDLNode added in v0.10.0 

func IsDDLNode(node sql.Node) bool

func IsNoRowNode added in v0.10.0

func NewIndexedInSubqueryFilter added in v0.9.0 

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 NewNotInSubquery 

func NewNotInSubquery(left sql.Expression, right sql.Expression) sql.Expression

func Walk 

func Walk(v Visitor, node sql.Node)

Walk traverses the plan tree in depth-first order. It starts by calling v.Visit(node); node must not be nil. If the visitor returned by v.Visit(node) is not nil, Walk is invoked recursively with the returned visitor for each children of the node, followed by a call of v.Visit(nil) to the returned visitor. If v.Visit(node) returns non-nil, then all children are walked, even if one of them returns nil for v.Visit().
