Hello,

I'm trying to display my database on my TableWidgetItem in PyQt.

This is a snippet of my SQLite part of the code:
        #---------------------------------------------------------------------
        self.loaddata()

    def loaddata(self):
        connection = sqlite3.connect("inventory.db")
        cursor = connection.cursor()
        cursor.execute('select * from items')

        tablerow=0
        results = cursor.fetchall()
        self.tableWidget.setRowCount(40)
        for row in results:
            self.tableWidget.setItem(tablerow, 0, QtWidgets.QTableWidgetItem(row[0]))
            self.tableWidget.setItem(tablerow, 1, QtWidgets.QTableWidgetItem(row[1]))
            self.tableWidget.setItem(tablerow, 2, QtWidgets.QTableWidgetItem(row[2]))
            tablerow+=1
        connection.close()
        #---------------------------------------------------------------------
But when I try to run my full script (shown below) I get an error saying there's no such table called 'items' (which is wrong because I already created the table and have some info loaded on it):
Error:
line 227, in loaddata
    cursor.execute('select * from items')
sqlite3.OperationalError: no such table: items
Am I displaying my SQLite database to my GUI properly? How Do I fix this error?


Any help would be greatly appreciated.

Thanks in advance.

Here's my full script right now:

Your database has no table items.

Here's an old example I made a few years ago. There you can select the table via ComboBox.

I tried adding WHERE type = table to my SELECT statement to be more specific but I get the same error.

My table is populated so I don't know what you mean by
Quote:Your database has no table items.
could you please clarify what you mean by that?

Here's the table (called items) that was created:
import sqlite3

def createDatabase():
        #Create a database (inventory.db)
        connection = sqlite3.connect("inventory.db")
        cursor = connection.cursor()

        table = """CREATE TABLE IF NOT EXISTS items
                (ID INTEGER PRIMARY KEY  AUTOINCREMENT,
                NAME           TEXT    NOT NULL,
                Quantity       INT     NOT NULL,
                Price          DOUBLE  NOT NULL,
                Sell_Price     DOUBLE,
                Description    TEXT,
                Category       TEXT,

Another thing I noticed is that you don't have to insert line endings in stylesheet. You can write it like this.

        self.AddItemButton.setStyleSheet("""background-color: rgb(85, 255, 0);
                                            border-style: outset;
                                            border-width: 2px;
                                            border-radius: 15px;
                                            border-color: black;
                                            padding: 4px;""")

FYI:

If you have any need for an SQLite database editor/viewer for use outside of your code, I'd recommend Db Browser: https://sqlitebrowser.org/
There may be a better one available, but this is simple, free, and complete.

Thanks, that got my table to display. The only problem is that just the item's name is displayed there is other other information there even through there's supposed to be.

For ex I added the following info to the items table:
NAME MG996R
Quantity 10
Price 5
Sell_Price 6
Description A Servo
Category Servos
Location S-1
Length_Ft
Barcode
Image
Date Updated

But all I get outputted to the table is the item Name:
MG996R
Nothing else.


My question is, why isn't the other info showing?

try this

    def loaddata(self):
        connection = sqlite3.connect("inventory.db")
        cursor = connection.cursor()
        cursor.execute('select * from items')
        row = 0
        self.InventoryDisplay.setRowCount(40)
        while True:
            form = cursor.fetchone()
            if form == None:
                break
            for column, item in enumerate(form):
                self.InventoryDisplay.setItem(row, column, QTableWidgetItem(str(item)))
                print(str(item))
            row += 1
        connection.close()
        #---------------------------------------------------------------------
