I had a similar problem using python 3 and sqlite via apsw:
```Python
Python 3.9.5 (tags/v3.9.5:0a7dcbd, May 3 2021, 17:27:52) [MSC v.1928 64 bit (AM
D64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import apsw, datetime, MetaTrader5 as mt5
>>> from contextlib import closing
>>> conn=apsw.Connection("C:\\Users\\Administrator\\AppData\\Roaming\\MetaQuotes\\Terminal\\D0E8209F77C8CF37AD8BF550E51FF075\\MQL5\\tgsignals.sqlite")
>>> conn.setbusytimeout(10000)
>>> mt5.initialize()
True
>>> utc_to = datetime.datetime.now().replace(tzinfo=datetime.timezone.utc).timestamp()
>>> utc_from = utc_to-300
>>> ratesm5 = mt5.copy_rates_range("USDJPY", mt5.TIMEFRAME_M5, utc_from, utc_to)
>>> curbar = ratesm5[0][0]
>>> curbar
1636024200
>>> type(curbar)
<class 'numpy.int64'>
```
inserting curbar into the 'time' field of table 'equity' led to the following unwanted result:
```Python
>>> with closing(conn.cursor()) as cursor:
... for row in cursor.execute("SELECT time, typeof(time) FROM equity"):
... print(row)
...
(b'\xa0\xd4\x83a\x00\x00\x00\x00', 'blob')
(b'\xcc\xd5\x83a\x00\x00\x00\x00', 'blob')
(b'\xf8\xd6\x83a\x00\x00\x00\x00', 'blob')
```
However the simple expedient of substituting *<code>curbar = ratesm5[0][0].item() </code>*for *<code>curbar = ratesm5[0][0]</code>* gave the desired output in the new lines:
```Python
>>> with closing(conn.cursor()) as cursor:
... for row in cursor.execute("SELECT time, typeof(time) FROM equity"):
... print(row)
...
(b'\xa0\xd4\x83a\x00\x00\x00\x00', 'blob')
(b'\xcc\xd5\x83a\x00\x00\x00\x00', 'blob')
(b'\xf8\xd6\x83a\x00\x00\x00\x00', 'blob')
(1636030200, 'integer')
(1636030500, 'integer')
```
Hope this helps someone...
