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 T2.Date_of_Birth FROM entrepreneur AS T1 JOIN people AS T2 ON T1.People_ID = T2.People_ID WHERE T1.Company = "Peter Jones" OR T1.Company = "Simon Woodroffe"
Feedback: There should be investor instead of company .

Answer: SELECT T2.Date_of_Birth FROM entrepreneur AS T1 JOIN people AS T2 ON T1.People_ID  =  T2.People_ID WHERE T1.Investor  =  "Simon Woodroffe" OR T1.Investor  =  "Peter Jones"


Question: SQL: SELECT name FROM buildings GROUP BY name HAVING Count ( * ) > 1
Feedback: Instep 1 , there should be company id of office locations instead of name in buildings table .

Answer: SELECT T2.name FROM Office_locations AS T1 JOIN buildings AS T2 ON T1.building_id  =  T2.id JOIN Companies AS T3 ON T1.company_id  =  T3.id GROUP BY T1.building_id HAVING COUNT(*)  >  1


Question: SQL: SELECT professional_id , last_name , home_phone FROM Professionals WHERE state = "Indiana" UNION SELECT professional_id , last_name , home_phone FROM Professionals GROUP BY professional_id HAVING Count ( * ) > = 2
Feedback: Exchange home phone with cell number in both step 1 and 3 and professionals table with treatments table in step 2.

Answer:
SELECT professional_id ,  last_name ,  cell_number FROM Professionals WHERE state  =  'Indiana' UNION SELECT T1.professional_id ,  T1.last_name ,  T1.cell_number FROM Professionals AS T1 JOIN Treatments AS T2 ON T1.professional_id  =  T2.professional_id GROUP BY T1.professional_id HAVING count(*)  >  2
