I have a table data
in a database data.sqlite
:
'my_path/data.sqlite'
A B
0 0
1 1
0 1
1 0
I would like to add a new column to this table, where each value = 1 if A = B, or 0 otherwise.
I can create a new column by doing:
conn = sqlite3.connect('my_path/data.sqlite')
cur = conn.cursor()
cur.execute("ALTER TABLE data ADD COLUMN Agreement")
conn.commit()
A B Agreement
0 0
1 1
0 1
1 0
I then try a conditional statement: where A and B are equal using the UPDATE SET CASE
function a la Conditional update in SQLite:
cur.execute("UPDATE data"
"SET Agreement = CASE WHEN A == B THEN 1 ELSE 0 END")
cur.commit()
But I keep getting:
OperationalError: near "Agreement": syntax error
What am I doing wrong?
