Question

how can I do an if statement to check if the column value is equal to an input value a user entered

I have a table called Tasks and a primary key called TaskID. How would the “if” condition look like if I am trying to compare an id a user entered, to the TaskID column

basically I am trying to do if(TaskID = 599) insert values

I have tried this so far:

if ((select TaskID from MyDB.dbo.Tasks where TaskID=599) = 599)
begin
insert into MyDB.dbo.Tasks (Concluded)
Values (1)
end

however I don’t think it has the result I want. It keeps creating a new task in stead.

Answer 1

Try this

IF EXISTS (SELECT 1 FROM task WHERE taskid=599)
    UPDATE MyDB.dbo.Tasks SET concluded = 1 WHERE taskid=599
ELSE
    INSERT INTO MyDB.dbo.Tasks (concluded) VALUES (1)
