Expected behavior:
Plan and AST. No error.
Steps to reproduce:
package main
import (
"context"
"fmt"
"github.com/ydb-platform/ydb-go-sdk/v3"
"github.com/ydb-platform/ydb-go-sdk/v3/query"
)
func main() {
ctx := context.TODO()
db, err := ydb.Open(ctx, "grpc://localhost:2136/local")
if err != nil {
panic(err)
}
defer db.Close(ctx) // cleanup resources
var (
ast string
plan string
)
err = db.Query().Exec(ctx,
`SELECT CAST(42 AS Uint32); SELECT CAST(43 AS Uint32);`,
query.WithExecMode(query.ExecModeExplain),
query.WithStatsMode(query.StatsModeNone, func(stats query.Stats) {
ast = stats.QueryAST()
plan = stats.QueryPlan()
}),
query.WithIdempotent(),
)
if err != nil {
panic(err)
}
fmt.Println(plan)
fmt.Println(ast)
}
