sqlite3.OperationalError: no such column: current_month_value

Question

In this code I'm trying to filter my database to get certain months clicked by the user and it is held by a variable called current_month_value. Whenever I query the database with curso.execute("SELECT * FROM page3 WHERE Month=current_month_value "). It gives an error that no such column exist, please what can I modify this query to get only the clicked month.

curso.execute("SELECT * FROM page3 WHERE Month=?", (current_month_value,))

In your version you put current_month_value inside string constant so sqlite thinks that it's column name, just like Month. You should define this as a parameter, using question mark ("?") and bind this parameter to its value, passing it via current_month_value variable

Although this code might solve the problem, a good answer should also explain **what** the code does and **how** it helps. – BDL Oct 13 '20 at 08:58
On running the code you wrote, it gives sqlite3.ProgrammingError: Incorrect number of bindings supplied. The current statement uses 1, and there are 0 supplied. – Simeoni Oct 13 '20 at 09:57
Is it possible that your variable is inside quotation marks and not outside? Did you close the string just after "?" sign? – Grisha Oct 13 '20 at 12:11
I edit the answer. The parameter must be passwed as tuple, as explained here: https://stackoverflow.com/questions/16856647/sqlite3-programmingerror-incorrect-number-of-bindings-supplied-the-current-sta – Grisha Oct 13 '20 at 16:08
It worked sir, thanks but there is a little problem. Firstly the value of the months I clicked isn't showing under the month table. Secondly Lets say I've been picking March as My Month and Suddenly I picked April, I expect it to give me data about the last selection which is April but I'm still seeing it carrying over Results of March into it. Is there anyway I can modify the query again sir ? – Simeoni Oct 13 '20 at 20:07
Dont worry sir, I already fixed the new issue by abstaining from using the variable curent_month_value but just calling FirstScreen.PressButton(button) – Simeoni Oct 13 '20 at 23:11
