sql - MySQL subquery returns more than one row

Question

I am executing this query:

SELECT
    voterfile_county.Name,
    voterfile_precienct.PREC_ID,
    voterfile_precienct.Name,
    COUNT((SELECT voterfile_voter.ID
FROM voterfile_voter
JOIN voterfile_household
WHERE voterfile_voter.House_ID = voterfile_household.ID
AND voterfile_household.Precnum = voterfile_precienct.PREC_ID)) AS Voters
FROM voterfile_precienct JOIN voterfile_county
WHERE voterfile_precienct.County_ID = voterfile_County.ID;

I am trying to make it return something like this:

County_Name   Prec_ID   Prec_Name   Voters(Count of # of voters in that precienct)

However, I am getting the error:

#1242 - Subquery returns more than 1 row.

I have tried placing the COUNT statement in the subquery but I get an invalid syntax error.

Answer 1

If you get error:error no 1242 Subquery returns more than one row, try to put ANY before your subquery. Eg:

This query return error:

SELECT * FROM t1 WHERE column1 = (SELECT column1 FROM t2);

This is good query:

SELECT * FROM t1 WHERE column1 = ANY (SELECT column1 FROM t2);
