# SQL Helper
This page contains some help if you want to edit your sqlite db.
## Install sqlite3
Sqlite3 is a terminal based sqlite application.
Feel free to use a visual Database editor like SqliteBrowser if you feel more comfortable with that.
### Ubuntu/Debian installation
```bash
sudo apt-get install sqlite3
```
### Using sqlite3 via docker-compose
The freqtrade docker image does contain sqlite3, so you can edit the database without having to install anything on the host system.
``` bash
docker-compose exec freqtrade /bin/bash
sqlite3 <database-file>.sqlite
```
## Open the DB
```bash
sqlite3
.open <filepath>
```
## Table structure
### List tables
```bash
.tables
```
### Display table structure
```bash
.schema <table_name>
```
## Get all trades in the table
```sql
SELECT * FROM trades;
```
## Fix trade still open after a manual sell on the exchange
!!! Warning
Manually selling a pair on the exchange will not be detected by the bot and it will try to sell anyway. Whenever possible, forcesell <tradeid> should be used to accomplish the same thing.
It is strongly advised to backup your database file before making any manual changes.
!!! Note
This should not be necessary after /forcesell, as forcesell orders are closed automatically by the bot on the next iteration.
```sql
UPDATE trades
SET is_open=0,
close_date=<close_date>,
close_rate=<close_rate>,
close_profit = close_rate / open_rate - 1,
close_profit_abs = (amount * <close_rate> * (1 - fee_close) - (amount * (open_rate * (1 - fee_open)))),
sell_reason=<sell_reason>
WHERE id=<trade_ID_to_update>;
```
### Example
```sql
UPDATE trades
SET is_open=0,
close_date='2020-06-20 03:08:45.103418',
close_rate=0.19638016,
close_profit=0.0496,
close_profit_abs = (amount * 0.19638016 * (1 - fee_close) - (amount * (open_rate * (1 - fee_open)))),
sell_reason='force_sell'
WHERE id=31;
```
## Remove trade from the database
!!! Tip "Use RPC Methods to delete trades"
Consider using `/delete <tradeid>` via telegram or rest API. That's the recommended way to deleting trades.
If you'd still like to remove a trade from the database directly, you can use the below query.
```sql
DELETE FROM trades WHERE id = <tradeid>;
```
```sql
DELETE FROM trades WHERE id = 31;
```
!!! Warning
This will remove this trade from the database. Please make sure you got the correct id and **NEVER** run this query without the `where` clause.
## Use a different database system
!!! Warning
By using one of the below database systems, you acknowledge that you know how to manage such a system. Freqtrade will not provide any support with setup or maintenance (or backups) of the below database systems.
### PostgreSQL
Freqtrade supports PostgreSQL by using SQLAlchemy, which supports multiple different database systems.
Installation:
`pip install psycopg2-binary`
Usage:
`... --db-url postgresql+psycopg2://<username>:<password>@localhost:5432/<database>`
Freqtrade will automatically create the tables necessary upon startup.
If you're running different instances of Freqtrade, you must either setup one database per Instance or use different users / schemas for your connections.
### MariaDB / MySQL
Freqtrade supports MariaDB by using SQLAlchemy, which supports multiple different database systems.
Installation:
`pip install pymysql`
Usage:
`... --db-url mysql+pymysql://<username>:<password>@localhost:3306/<database>`
