instruction:
In this task you are expected to fix an SQL query based on feedback. You will be given an SQL statement and an English description with what is wrong about that SQL statement. You must correct the SQL statement based off of the feedback. An SQL query works by selecting data from a table where certain conditions apply. A table contains columns where every row in that table must have a value for each column. Every table has a primary key that uniquely identifies each row, usually an id. To choose which columns are returned you specify that after the "SELECT" statement. Next, you use a "FROM" statement to specify what tables you want to select the data from. When you specify a table you can rename it with the "AS" statement. You can reference that table by whatever name follows the "AS" statement. If you want to select data from multiple tables you need to use the "JOIN" statement. This will join the tables together by pairing a row in one table with every row in the other table (Cartesian Product). To limit the number of rows returned you should use the "ON" statement. This will only return rows where the condition specified after the statement is true, this is usually an equals operator with primary keys. You can also use the "WHERE" statement to specify that only rows with column values statisfying a certain condition, should be returned. The "GROUP BY" statement will group rows together that have equal column values for whatever columns follows the statement. The "HAVING" statement will return groups that statisfy whatever condition follows the statement. Any column(s) being returned from grouped rows must either be an aggregate function, (AVG, MAX, COUNT, SUM, ...) of a column, or the column(s) that the data was grouped by. To sort the returned data you can use the "ORDER BY" command which will order the data by whatever aggregate function or column follows the statement. The "DESC" statement will sort in descending order and the "ASC" statement will sort in ascending order. Finally, you can use the "LIMIT" statement to return a certain number of rows. When "*" is used in an SQL statement every column is returned. For example, SELECT * FROM table WHERE attribute = 1, will select every column from rows with the attribute column equal to 1. 
question:
SQL: SELECT T1.decor FROM Rooms AS T1 JOIN Reservations AS T2 ON T1.RoomId = T2.Room GROUP BY T2.Room ORDER BY Count ( * ) Desc LIMIT 1
Feedback: Need to find highest number of reservations instead of decor .
answer:
SELECT T2.roomName FROM Reservations AS T1 JOIN Rooms AS T2 ON T1.Room  =  T2.RoomId GROUP BY T1.Room ORDER BY count(*) DESC LIMIT 1


question:
SQL: SELECT T2.Name FROM museum AS T1 JOIN visitor AS T2 JOIN visit AS T3 ON T1.Museum_ID = T3.Museum_ID AND T3.visitor_ID = T2.ID WHERE T1.Open_Year > 2009 INTERSECT SELECT T2.Name FROM museum AS T1 JOIN visitor AS T2 JOIN visit AS T3 ON T1.Museum_ID = T3.Museum_ID AND T3.visitor_ID = T2.ID WHERE T1.Open_Year < 2011
Feedback: Ensure that open year less than 2009 in step 2 , Make sure open year greater than 2011 in step 3.
answer:
SELECT t1.name FROM visitor AS t1 JOIN visit AS t2 ON t1.id  =  t2.visitor_id JOIN museum AS t3 ON t3.Museum_ID  =  t2.Museum_ID WHERE t3.open_year  <  2009 INTERSECT SELECT t1.name FROM visitor AS t1 JOIN visit AS t2 ON t1.id  =  t2.visitor_id JOIN museum AS t3 ON t3.Museum_ID  =  t2.Museum_ID WHERE t3.open_year  >  2011


question:
SQL: SELECT customer_name FROM Customers GROUP BY customer_name ORDER BY Count ( * ) Desc LIMIT 1
Feedback: Discard customer name in customers table , use Mailshot Customers's customer id in step 1 in place of that .
answer:

SELECT T2.customer_name FROM mailshot_customers AS T1 JOIN customers AS T2 ON T1.customer_id  =  T2.customer_id GROUP BY T1.customer_id ORDER BY count(*) DESC LIMIT 1
