Es sieht so aus, als würden Sie gleichzeitig versuchen, Rückrufe durchzuführen und zu asynchronisieren/zu warten.
const {Pool, Client} = require('pg')
const connectionString = 'postgressql://[email protected]:5432/database'
const client = new Client({
connectionString:connectionString
})
client.connect()
database_func()
async function database_func() {
// You should be doing callbacks OR async/await whenever you call a query,
// You're doing both at the same time
client.query(`SELECT t FROM es ORDER BY t DESC LIMIT 1;`, (err,res) => {
console.log('res')
return;
})
// OR
let res;
try {
res = await client.query(`SELECT t FROM es ORDER BY t DESC LIMIT 1;`);
} catch (err) {
console.error(err);
}
console.log(res);
client.end();
console.log('after res')
}
