I would like to use promise too.
For example I would like to use something like this
function pgCursorPromise(cursor, itemNum){
return new Promise(function(resolve,reject){
cursor.read(itemNum, (err, rows) => {
if (err) {
return reject(err);
}
resolve(rows);
});
});
}
.....
const client = await global.pgpool.connect();
try{
let rows;
let totalRows = 0;
const cursor = client.query(new Cursor('select * from accounts'));
while ((rows = await pgCursorPromise(cursor, 100)) && rows.length > 0){
for(let row of rows){
// do the actual work here
}
}
} catch (err) {
console.log(err);
} finally {
client.release();
}
from node-pg-cursor.
