Update Table1 adding values from Table2 - sql-server

Question

Table1
Columns PK_Table1 Name | DoYouGoToSchool |DoYouhaveACar |DoYouWorkFullTime | DoYouWorkPartTime | Score
1 joe Yes Yes No Yes
2 amy No Yes Yes No
Table2
Columns Pk_Table2 |Question | Answer(Bit Column) |Value
1 DoYouGoToSchool True 3
2 DoYouhaveACar True 2
3 DoYouWorkFullTime True 4
4 DoYouWorkPartTime True 2
Based on the information from Table2 What i need to do is UPDATE Table1 ColumnName Score by summing up the Value from Table2 with the information he has provided.
for example i expect the Score column in table1 to be 7 for record 1
and 5 for record 2
Here is a query to play with
IF OBJECT_ID('tempdb..#Table2') IS NOT NULL DROP TABLE #Table2
GO
IF OBJECT_ID('tempdb..#Table1') IS NOT NULL DROP TABLE #Table1
GO
create table #Table1
(
PK_Table1 int,
Name Varchar(50),
DoYouGoToSchool Varchar(8),
DoYouhaveACar Varchar(8),
DoYouWorkFullTime Varchar(8),
DoYouWorkPartTime Varchar(8),
Score INT NULL,
)
create table #Table2
(
PK_Table2 int,
Questions Varchar(50),
Answer BIT NOT NULL DEFAULT(0),
VALUE INT NULL
)
INSERT INTO #Table1 (Name,DoYouGoToSchool,DoYouhaveACar,DoYouWorkFullTime,DoYouWorkPartTime)
VALUES ('joe','Yes','Yes','No','Yes'), ('amy','NO','Yes','Yes','No')
INSERT INTO #Table2(Questions,Answer,VALUE)
VALUES ('DoYouGoToSchool','True',3 ),('DoYouhaveACar','True',2 ),('DoYouWorkFullTime','True',4 ),('DoYouWorkPartTime','True',2 )
This is what is missing from answer below that tells you to create new FK contraint to the Table2 --Inserting Data into the table with the new FK Column
insert into #Table2 (FK_Table1, Questions, Answer) select t.PK_Table1, t1.cols, colsval from #Table1 t cross apply (values (PK_Table1,'DoYouGoToSchool', DoYouGoToSchool), (PK_Table1,'DoYouhaveACar', DoYouhaveACar), (PK_Table1,'DoYouWorkFullTime', DoYouWorkFullTime), (PK_Table1,'DoYouWorkPartTime', DoYouWorkPartTime) ) t1 (PK_Table1,cols, colsval);

Answer 1

First create a relation between these two tables and add Primary key of Table1 in Table2 as a foreign key so your Table2 becomes:
Table2 Columns:
FK_Table1 |Pk_Table2 |Question | Answer(Bit Column) |Value
1 1 DoYouGoToSchool True 3
1 2 DoYouhaveACar True 2
1 3 DoYouWorkFullTime True 4
1 4 DoYouWorkPartTime True 2
You can add in table by using this Query:
ALTER TABLE Table2
ADD FK_Table1 INTEGER,
ADD CONSTRAINT FOREIGN KEY(FK_Table1) REFERENCES Table1(PK_Table1)
means that it is only for that person whose PK_Table1 = 1
Then you can extract his score from this query:
SELECT Sum(Value) FROM Table2 WHERE FK_Table1 = 1;
And then update query:
UPDATE Table1
SET score = (enter here the returned score from above query)
WHERE PK_Table1 = 1;
Or you can do in a single query like this:
UPDATE Table1
SET score = (SELECT Sum(Value) FROM Table2 WHERE FK_Table1 = 1)
WHERE PK_Table1 = 1;

Answer 2

You will need to add another table. This table will be your relational table. It can be called Table1_Table2 with three columns. The first column will be the primary key for the table. The next column will be the primary key of Table1 and the third column will be the primary key for Table 2.
When an instance of Table2 occurs that relates with Table1, insert a record into Table1_Table2 that relates the two tables together with each others primary key. Then a query can be done on the relational table, Table1_Table2 that allows you to sum the relationships.
|Table1_Table2 |
| PK | PK_Table1 | PK_Table2 |
| 1 | 1 | 1 |
| 2 | 1 | 3 |
| 3 | 2 | 1 |
| 4 | 2 | 4 |
As we can see, we can now perform an update on Table1
UPDATE TABLE1 A SET A.SCORE = (Select SUM(B.Value) FROM Table2 B, Table1_Table2 C WHERE C.PK_Table2 = B.PK_Table2 AND C.PK_Table1 = A.PK_Table1);
