Functions ¶

func ExtractPreparedStmtTextsFromSetSessionStatesSQL ¶

func ExtractPreparedStmtTextsFromSetSessionStatesSQL(sql string) map[uint32]string

ExtractPreparedStmtTextsFromSetSessionStatesSQL is a best-effort helper to extract stmtID -> SQL text.

Types ¶

type PreparedStmtInfo ¶

type PreparedStmtInfo struct {
	StmtText   string `json:"text"`
	ParamTypes []byte `json:"types,omitempty"`
}

type SessionStates ¶

type SessionStates struct {
	PreparedStmts map[uint32]*PreparedStmtInfo `json:"prepared-stmts,omitempty"`
}

SessionStates mirrors TiDB session states JSON schema partially. Currently we only need prepared statements for traffic capture / replay.

func ParseFromSetSessionStatesSQL ¶

func ParseFromSetSessionStatesSQL(sql string) (SessionStates, error)

ParseFromSetSessionStatesSQL parses a SQL string like: SET SESSION_STATES '...json...' and returns its decoded SessionStates. If sql is not a SET SESSION_STATES statement, it returns an empty SessionStates and nil error.
