I’m not familiar with MSSQL, but with other databases, I would suggest attempting to insert the new record (assuming there is a unique key to prevent duplicate records) and then either catch (if I cared) or ignore (if I don’t care) the duplicate key exception and then issue the UPDATE; or attempt the update, check the number of rows affected, and if it was zero, run the insert.
Here is simple example, what I tried to do. I can't get f string to work in my case to use it as table name placeholder and I can't figure it out, what you are suggesting (I'm beginner and English is not my primary language):
I am not sure how to create placeholders in Postgres. I did some research - I found some posts on Stackoverflow and tutorials on Postgres that suggested I used "$1, $2" or use "%s, %l" as a placeholder. However, I keep getting errors. Does anyone have any suggestions?
The character after the at sign @ in the placeholder key is the transformation that is applied to the argument before inserting it into the placeholder (S for raw SQL, I for Identifiers and L for literals, among others).
hi, i have a pollsystem with buttons where i want to update the labels of the buttons after been clicked.
Technically, you have the right amount, but you're missing parentheses and commas, and it's broken up throughout your query which I suspect is confusing SQL. Just like the values are separated with commas and surrounded in parentheses, so too must the placeholders.
It only seems to be these two lines, as I have other queries with LIKE statements that work no issue. I have other commands with a "%s" placeholder in the middle, and a LIKE statement, and those work no issue. And as mentioned, they worked no problem when I was using sqlite, but since switching they don't.
In Postgres, the value placeholder is $#, which one is recommend when the value is the same, reusing the value placeholder or not? db.Exec("INSERT…
I'm trying to connect to Sage 50 using pyodbc. I'm able to get my data out if I input the bank account directly into the sql query however if I try to insert the value into the query I get the following error: ('HY004', '[HY004] [Microsoft][ODBC Driver Manager] SQL data type out of range (0) (SQLBindParameter)')
Now I want to do the same thing via inline queries so that queries can be made through any chat. Have used the /setinline command and set a placeholder, which appears when I make the inline query, and type the command and param, but I don't know where it's going. The article on inline queries says "The query is sent to your bot in an update."
