Constants ¶
const ExtendedTypeTag = "extended_"
ExtendedTypeTag is primarily used by ParseColumnTypeString when parsing strings representing extended types
const OnDupValuesPrefix = "__new_ins"
Variables ¶
var ( ErrPrimaryKeyOnNullField = errors.NewKind("All parts of PRIMARY KEY must be NOT NULL") // ErrUnionSchemasDifferentLength is returned when the two sides of a // UNION do not have the same number of columns in their schemas. ErrUnionSchemasDifferentLength = errors.NewKind( "cannot union two queries whose schemas are different lengths; left has %d column(s) right has %d column(s).", ) ErrQualifiedOrderBy = errors.NewKind("Table '%s' from one of the SELECTs cannot be used in global ORDER clause") ErrOrderByBinding = errors.NewKind("bindings in sort clauses not supported yet") ErrFailedToParseStats = errors.NewKind("failed to parse data: %s\n%s") )
var BinderFactory = &sync.Pool{New: func() interface{} { return &Builder{f: &factory{}} }}
var ErrMaxAnalysisIters = errors.NewKind("exceeded max analysis iterations (%d)")
ErrMaxAnalysisIters is thrown when the analysis iterations are exceeded
Functions ¶
func BuildProcedureHelper ¶ added in v0.20.0
func DeepCopyNode ¶
DeepCopyNode copies a sql.Node.
func ExpressionToColumnDefaultValue ¶
func ExpressionToColumnDefaultValue(inputExpr sql.Expression, isLiteral, isParenthesized bool) *sql.ColumnDefaultValue
ExpressionToColumnDefaultValue takes in an Expression and returns the equivalent ColumnDefaultValue if the expression is valid for a default value. If the expression represents a literal (and not an expression that returns a literal, so "5" rather than "(5)"), then the parameter "isLiteral" should be true.
func MustStringToColumnDefaultValue ¶ added in v0.17.0
func MustStringToColumnDefaultValue(ctx *sql.Context, exprStr string, outType sql.Type, nullable bool) *sql.ColumnDefaultValue
MustStringToColumnDefaultValue is used for creating default values on tables that do not go through the analyzer. Does not handle function nor column references.
func Parse ¶
Parse parses the given SQL |query| using the default parsing settings and returns the corresponding node.
func ParseColumnTypeString ¶ added in v0.17.0
func ParseWithOptions ¶ added in v0.17.0
func StringToColumnDefaultValue ¶ added in v0.17.0
StringToColumnDefaultValue takes in a string representing a default value and returns the equivalent Expression.
Types ¶
type BindvarContext ¶ added in v0.18.0
type BindvarContext struct {
Bindings map[string]sql.Expression
// contains filtered or unexported fields
}
BindvarContext holds bind variable replacement literals.
func (*BindvarContext) GetSubstitute ¶ added in v0.18.0
func (bv *BindvarContext) GetSubstitute(s string) (sql.Expression, bool)
func (*BindvarContext) UnusedBindings ¶ added in v0.18.0
func (bv *BindvarContext) UnusedBindings() []string
type Builder ¶ added in v0.17.0
type Builder struct {
// contains filtered or unexported fields
}
func New ¶ added in v0.17.0
New takes ctx, catalog, event scheduler, and parser. If the parser is nil, then default parser is mysql parser.
func (*Builder) BindCtx ¶ added in v0.18.0
func (b *Builder) BindCtx() *BindvarContext
func (*Builder) BuildColumnDefaultValueWithTable ¶ added in v0.19.0
func (*Builder) BuildScalarWithTable ¶ added in v0.19.0
func (*Builder) ConvertVal ¶ added in v0.17.0
func (b *Builder) ConvertVal(v *ast.SQLVal) sql.Expression
func (*Builder) DisableAuth ¶ added in v0.19.0
func (b *Builder) DisableAuth()
DisableAuth disables all authorization checks.
func (*Builder) EnableAuth ¶ added in v0.19.0
func (b *Builder) EnableAuth()
EnableAuth enables all authorization checks. Auth is enabled by default, so this only needs to be called when it was previously disabled using DisableAuth.
func (*Builder) NewFrame ¶ added in v0.17.0
func (b *Builder) NewFrame(inScope *scope, f *ast.Frame) sql.WindowFrame
func (*Builder) ProcCtx ¶ added in v0.17.0
func (b *Builder) ProcCtx() *ProcContext
func (*Builder) ResolveSchemaDefaults ¶ added in v0.20.0
ResolveSchemaDefaults resolves any column default value expressions for the specified |schema|, for the table named |tableName| and returns the schema with the default value expressions resolved. Note that any GetField expressions in the column default value expressions have not had their indexes corrected yet.
func (*Builder) SetBindings ¶ added in v0.18.0
func (*Builder) SetBindingsWithExpr ¶ added in v0.19.0
func (b *Builder) SetBindingsWithExpr(bindings map[string]sql.Expression)
func (*Builder) SetParserOptions ¶ added in v0.17.0
func (b *Builder) SetParserOptions(opts ast.ParserOptions)
func (*Builder) TriggerCtx ¶ added in v0.17.0
func (b *Builder) TriggerCtx() *TriggerContext
func (*Builder) ViewCtx ¶ added in v0.17.0
func (b *Builder) ViewCtx() *ViewContext
type ProcContext ¶ added in v0.17.0
type ProcContext struct {
AsOf interface{}
DbName string
}
ProcContext allows nested CALLs to use the same database for resolving procedure definitions without changing the underlying database roots.
type TriggerContext ¶ added in v0.17.0
type ViewContext ¶ added in v0.17.0
type ViewContext struct {
AsOf interface{}
DbName string
}
ViewContext overwrites database root source of nested calls.
