Types

type Statement

type Statement interface {
	// Explain gets the execution plans.
	Explain(ctx context.Context, w format.Formatter)

	// IsDDL shows whether the statement is an DDL operation.
	IsDDL() bool

	// OriginText gets the origin SQL text.
	OriginText() string

	// SetText sets the executive SQL text.
	SetText(text string)

	// Exec executes SQL and gets a Recordset.
	Exec(ctx context.Context) (rset.Recordset, error)
}

Statement is an interface for SQL execution. NOTE: all Statement implementations must be safe for concurrent using by multiple goroutines. If the Exec method requires any Execution domain local data, they must be held out of the implementing instance.
