Bulk insert with sqlx

Question

I'am trying to make a bulk insert with sqlx and golang :

    for _, result := range results {
            queryInsert := `INSERT INTO "DataCom_travel" (com1,com2,path,time) VALUES ($1,$2,$3,$4)`
            db.MustExec(queryInsert,result.Com1,result.Com2,result.Path,result.Time)
            queryUpdate := `UPDATE "DataCom_commcombinaison" set done = TRUE WHERE com1 =$1 and com2 =$2`
            db.MustExec(queryUpdate,result.Com1,result.Com2)
        }

That code works but it's slow.

I've tried this :

tx := db.MustBegin()
for _, result := range results {
        queryInsert := `INSERT INTO "DataCom_travel" (com1,com2,path,time) VALUES ($1,$2,$3,$4)`
        tx.MustExec(queryInsert,result.Com1,result.Com2,result.Path,result.Time)
        queryUpdate := `UPDATE "DataCom_commcombinaison" set done = TRUE WHERE com1 =$1 and com2 =$2`
        tx.MustExec(queryUpdate,result.Com1,result.Com2)
    }
tx.Commit()

but it does nothing when i look at my records i doesn't see any records.

Regards

edit :

INSERT INTO "DataCom_travel" (com1,com2,path,time) VALUES ($1,$2,$3,$4),($2,$3,$4,$5),($3,$4,$5,$6),($4,$5,$6,$7),($5,$6,$7,$8),($6,$7,$8,$9),($7,$8,$9,$10),($8,$9,$10,$11),($9,$10,$11,$12),($10,$11,$12,$13)
UPDATE "DataCom_commcombinaison" set done = TRUE WHERE (com1 = $1 AND com2 = $2 )  OR (com1 = $2 AND com2 = $3 )  OR (com1 = $3 AND com2 = $4 )  OR (com1 = $4 AND com2 = $5 )  OR (com1 = $5 AND com2 = $6 )  OR (com1 = $6 AND com2 = $7 )  OR (com1 = $7 AND com2 = $8 )  OR (com1 = $8 AND com2 = $9 )  OR (com1 = $9 AND com2 = $10 )  OR (com1 = $10 AND com2 = $11 ) 
panic: pq: column "com2" is of type integer but expression is of type text

You can use NamedExec instead of string concatenation.

This example is from the sqlx ReadMe

// batch insert with maps
personMaps := []map[string]interface{}{
        {"first_name": "Ardie", "last_name": "Savea", 
         "email": "[email protected]"},
        {"first_name": "Sonny Bill", "last_name": "Williams", 
         "email": "[email protected]"},
        {"first_name": "Ngani", "last_name": "Laumape", 
         "email": "[email protected]"},
}

_, err = db.NamedExec(`INSERT INTO person 
             (first_name, last_name, email)
        VALUES 
             (:first_name, :last_name, :email)`, personMaps)
