I'm running a list of sql files. The list of files comes from the same sqlite3 db that I'm going to execute sql against, hence there's only one db connection. If I don't kill the loop over sql files it will return "database is locked" error for every file starting with the first. Things that didn't work:
No effect: Adding rows.Close() from Sqlite3 error: database is locked in golang
Removing sqlx and using database/sql didn't change anything.
No effect: Having Navicat open or closed.
Restarting my laptop, no effect.
No effect: Dumping database to a new file then running the process against the new file.
package main
import (
"database/sql"
"fmt"
"io/ioutil"
"os"
_ "github.com/mattn/go-sqlite3"
)
func main() {
dbPath := "/Users/darianhickman/Documents/wc_study/history.db"
db, err := sql.Open("sqlite3", dbPath)
if err != nil {
println("db open failed.", err)
os.Exit(-1)
}
defer db.Close()
// qry := `select list_folder||'/'|| sql_file as script from run_list where 'order' > 0 ORDER BY 'order'; `
qry := `select list_folder||'/'|| sql_file as script from run_list
where run_order > 0
ORDER BY run_order;`
scripts, err := db.Query(qry)
if err != nil {
println("query failed ", qry)
os.Exit(-1)
}
defer scripts.Close()
var file string
for scripts.Next() {
err = scripts.Scan(&file)
if err != nil {
println(err)
}
println(file[len(file)-80:])
sqlScript, err := ioutil.ReadFile(file)
if err != nil {
println("reading script file failed\n", file)
}
if _, err := db.Exec(string(sqlScript)); err != nil {
fmt.Println(string(sqlScript[:80]))
fmt.Println(err)
} else {
fmt.Println("Success ", string(sqlScript[:80]))
}
}
}
Per @kostix observation, I gave up on reading the list of scripts while executing the scripts and that worked.
package main
import (
"fmt"
"io/ioutil"
"github.com/jmoiron/sqlx"
_ "github.com/mattn/go-sqlite3"
)
func main() {
// dbPath := "file:/Users/darianhickman/Documents/wc_study/history.db?cache=shared"
dbPath := "file:/Users/darianhickman/Documents/wc_study/history.db"
db := sqlx.MustConnect("sqlite3", dbPath)
defer db.Close()
// db.SetMaxOpenConns(1)
// qry := `select list_folder||'/'|| sql_file as script from run_list where 'order' > 0 ORDER BY 'order'; `
qry := `select list_folder||'/'|| sql_file as script from run_list
where run_order > 0
ORDER BY run_order;`
scripts, err := db.Query(qry)
if err != nil {
println("script qry failed ", qry)
}
defer scripts.Close()
var files []string
var file string
// Giving up on executing sql scripts while reading the query of scripts.
for scripts.Next() {
err = scripts.Scan(&file)
if err != nil {
println(err)
} else {
files = append(files, file)
}
}
for _, file := range files {
println(file[len(file)-80:])
sqlScript, err := ioutil.ReadFile(file)
if err != nil {
println("reading script file failed\n", file)
}
if _, err := db.Exec(string(sqlScript)); err != nil {
fmt.Println(string(sqlScript[:80]))
fmt.Println(err)
} else {
fmt.Println("Success ", string(sqlScript[:80]))
}
}
}
