Types ¶
type StatementContext ¶
type StatementContext struct { // IsDDLJobInQueue is used to mark whether the DDL job is put into the queue. // If IsDDLJobInQueue is true, it means the DDL job is in the queue of storage, and it can be handled by the DDL worker. IsDDLJobInQueue bool InInsertStmt bool InUpdateOrDeleteStmt bool InSelectStmt bool IgnoreTruncate bool IgnoreZeroInDate bool DupKeyAsWarning bool BadNullAsWarning bool DividedByZeroAsWarning bool TruncateAsWarning bool OverflowAsWarning bool InShowWarning bool UseCache bool PadCharToFullLength bool BatchCheck bool InNullRejectCheck bool // Copied from SessionVars.TimeZone. TimeZone *time.Location Priority mysql.PriorityEnum NotFillCache bool MemTracker *memory.Tracker TableIDs []int64 IndexIDs []int64 // contains filtered or unexported fields }
StatementContext contains variables for a statement. It should be reset before executing a statement.
func (*StatementContext) AddAffectedRows ¶
func (sc *StatementContext) AddAffectedRows(rows uint64)
AddAffectedRows adds affected rows.
func (*StatementContext) AddFoundRows ¶
func (sc *StatementContext) AddFoundRows(rows uint64)
AddFoundRows adds found rows.
func (*StatementContext) AffectedRows ¶
func (sc *StatementContext) AffectedRows() uint64
AffectedRows gets affected rows.
func (*StatementContext) AppendError ¶
func (sc *StatementContext) AppendError(warn error)
AppendError appends a warning with level 'Error'.
func (*StatementContext) AppendNote ¶
func (sc *StatementContext) AppendNote(warn error)
AppendNote appends a warning with level 'Note'.
func (*StatementContext) AppendWarning ¶
func (sc *StatementContext) AppendWarning(warn error)
AppendWarning appends a warning with level 'Warning'.
func (*StatementContext) FoundRows ¶
func (sc *StatementContext) FoundRows() uint64
FoundRows gets found rows.
func (*StatementContext) GetExecDetails ¶
func (sc *StatementContext) GetExecDetails() execdetails.ExecDetails
GetExecDetails gets the execution details for the statement.
func (*StatementContext) GetWarnings ¶
func (sc *StatementContext) GetWarnings() []SQLWarn
GetWarnings gets warnings.
func (*StatementContext) HandleOverflow ¶
func (sc *StatementContext) HandleOverflow(err error, warnErr error) error
HandleOverflow treats ErrOverflow as warnings or returns the error based on the StmtCtx.OverflowAsWarning state.
func (*StatementContext) HandleTruncate ¶
func (sc *StatementContext) HandleTruncate(err error) error
HandleTruncate ignores or returns the error based on the StatementContext state.
func (*StatementContext) HistogramsNotLoad ¶
func (sc *StatementContext) HistogramsNotLoad() bool
HistogramsNotLoad gets histogramsNotLoad.
func (*StatementContext) MergeExecDetails ¶
func (sc *StatementContext) MergeExecDetails(details *execdetails.ExecDetails)
MergeExecDetails merges a single region execution details into self, used to print the information in slow query log.
func (*StatementContext) NumWarnings ¶
func (sc *StatementContext) NumWarnings(errOnly bool) uint16
NumWarnings gets warning count. It's different from `WarningCount` in that `WarningCount` return the warning count of the last executed command, so if the last command is a SHOW statement, `WarningCount` return 0. On the other hand, `NumWarnings` always return number of warnings(or errors if `errOnly` is set).
func (*StatementContext) ResetForRetry ¶
func (sc *StatementContext) ResetForRetry()
ResetForRetry resets the changed states during execution.
func (*StatementContext) SetHistogramsNotLoad ¶
func (sc *StatementContext) SetHistogramsNotLoad()
SetHistogramsNotLoad sets histogramsNotLoad.
func (*StatementContext) SetWarnings ¶
func (sc *StatementContext) SetWarnings(warns []SQLWarn)
SetWarnings sets warnings.
func (*StatementContext) WarningCount ¶
func (sc *StatementContext) WarningCount() uint16
WarningCount gets warning count.
