FormatImpossibleQuery creates an impossible query in a TrackedBuffer. An impossible query is a modified version of a query where all selects have where clauses that are impossible for mysql to resolve. This is used in the vtgate and vttablet:
- In the vtgate it's used for joins: if the first query returns no result, then vtgate uses the impossible query just to fetch field info from vttablet - In the vttablet, it's just an optimization: the field info is fetched once form MySQL, cached and reused for subsequent queries

func CloneSliceOfVindexParam(n []VindexParam) []VindexParam
CloneSliceOfVindexParam creates a deep clone of the input.
func CloneVindexParam ¶ added in v0.10.0
func CloneVindexParam(n VindexParam) VindexParam
CloneVindexParam creates a deep clone of the input.
func (*VindexParam) CachedSize ¶ added in v0.10.0
func (cached *VindexParam) CachedSize(alloc bool) int64
func (VindexParam) Format ¶
func (node VindexParam) Format(buf *TrackedBuffer)
Format formats the node.
type VindexSpec ¶
type VindexSpec struct { Name ColIdent Type ColIdent Params []VindexParam }
VindexSpec defines a vindex for a CREATE VINDEX or DROP VINDEX statement
func CloneRefOfVindexSpec ¶ added in v0.10.0
func CloneRefOfVindexSpec(n *VindexSpec) *VindexSpec
CloneRefOfVindexSpec creates a deep clone of the input.
func (*VindexSpec) CachedSize ¶ added in v0.10.0
func (cached *VindexSpec) CachedSize(alloc bool) int64
func (*VindexSpec) Format ¶
func (node *VindexSpec) Format(buf *TrackedBuffer)
Format formats the node. The "CREATE VINDEX" preamble was formatted in the containing DDL node Format, so this just prints the type, any parameters, and optionally the owner
func (*VindexSpec) ParseParams ¶
func (node *VindexSpec) ParseParams() (string, map[string]string)
ParseParams parses the vindex parameter list, pulling out the special-case "owner" parameter
type Visit ¶
Visit defines the signature of a function that can be used to visit all nodes of a parse tree. returning false on kontinue means that children will not be visited returning an error will abort the visitation and return the error
type When ¶
When represents a WHEN sub-expression.
func CloneRefOfWhen ¶ added in v0.10.0
CloneRefOfWhen creates a deep clone of the input.
func CloneSliceOfRefOfWhen ¶ added in v0.10.0
CloneSliceOfRefOfWhen creates a deep clone of the input.
func (*When) CachedSize ¶ added in v0.10.0
type Where ¶
Where represents a WHERE or HAVING clause.
func CloneRefOfWhere ¶ added in v0.10.0
CloneRefOfWhere creates a deep clone of the input.
func NewWhere ¶
NewWhere creates a WHERE or HAVING clause out of a Expr. If the expression is nil, it returns nil.
func (*Where) CachedSize ¶ added in v0.10.0
type XorExpr ¶
type XorExpr struct {
Left, Right Expr
}
XorExpr represents an XOR expression.
func CloneRefOfXorExpr ¶ added in v0.10.0
