sqlite3列不存在

Question

I am trying to run queries on an sqlite3 db/table i have made but i keep getting the error

Error: near line 4: no such column: number_of_officers_employed

Error: near line 6: no such column: year

Error: near line 8: no such column: year

Error: near line 10: no such column: year

My create-table code looks like this:

CREATE TABLE IF NOT EXISTS lwenfemp(year INTEGER PRIMARY KEY, us_population INTEGER, number_of_officers_employed INTEGER, percent_change INTEGER, officers_per_100000_residents INTEGER);

Any idea why this might be? i am fairly new to sqlite3 and apologise if i missed something that is obvious

My queries look like this:

SELECT year WHERE officers_per_100000_residents > '245';

Answer 1

Try add FROM table name:

SELECT year FROM lwenfemp WHERE officers_per_100000_residents > '245';

It will be fine, when using the backticks ``

SELECT `year` FROM lwenfemp WHERE officers_per_100000_residents > '245';
