Question

I’m getting a confusing select…where result, the table definition is:

CREATE TABLE modes (
               key INTEGER,
               mode INTEGER,
               channel INTEGER,
               name TEXT,
               short_name TEXT,
               def INTEGER,
               highlight INTEGER,
               catagory TEXT,
               subcatagory TEXT);

It’s populated with:

sqlite> select * from modes;
  3|6|5|Green|G|0|255|a|b
  3|6|6|Blue|B|0|255|a|b
  3|9|1|Mode|Mode|0|255|a|b
  3|9|2|Auto Mode Speed|Speed|0|255|a|b
  3|9|3|Strobe|Strobe|0|255|a|b
  3|9|4|Red|R|0|255|a|b
  3|9|5|Green|G|0|255|a|b
  3|9|6|Blue|B|0|255|a|b
  3|9|7|Red2|R2|0|255|a|b
  3|9|8|Green2|G2|0|255|a|b
  3|9|9|Blue2|B2|0|255|a|b
  3|6|4|Red|R|0|255|a|b
  3|6|1|6|6|0|255|a|b
  3|6|2|Auto mode speed|speed|0|255|a|b
  3|6|3|Strobe|Strobe|0|255|strobe|b

Note the row 3rd from the bottom:
3|6|1|6|6|0|255|a|b

If I do a select:
SELECT * FROM modes where mode=6 and name="Mode" order by channel;

It returns:
3|6|1|6|6|0|255|a|b

Columns 4 and 5 (name and short_name) should not match, they are 6 and the match term is “Mode”. If I change the match string “Mode” to any other string it works as expected. Is “Mode” a reserved word? or Did I somehow set a variable “Mode” to 6?. I don’t understand this behavior.

Answer 1

If you use [“] it means columns, so when you do

name="Mode"

it means you search in column name that have same value as column Mode. So you select where mode=6 and name=6 actually on your code.
If you want to use string, use [‘] not [“]

I try to use that code on my database..

select * from products
where name="Mode"

And I got error

ERROR:  column "Mode" does not exist
LINE 2: where name="Mode"
