I am trying to write a BigQuery to get distinct values from one table say ABC
select distinct name from dataset.abc
1
2
3
4
now I want to insert these values to another table say XYZ, which also contains column as name and another column as company.
Note: the company column can be duplicated as I want the to have all 4 rows against every company to be inserted in table ABC.
I need a BigQuery to do this dynamically instead of updating every dataset manually every time.
P.S. Sorry if my question is not as per standards as this is the first time I am posting on Stackoverflow.

I'm trying to create a new column in my SQL table that contains a simple multiplication based on an existing column.
Example of the existing table:
Product
PricingUSD
Product A
20
Product B
40
What I want to do:
Product
PricingUSD
PricingEUR
Product A
20
20.48
Product B
40
40.96
I created the new column with:
ALTER TABLE table
ADD 'PricingEUR' NUMERIC(10);
But now I'm not sure how to populate the new column (it is populated with NULL). It needs to take the number from "PricingUSD" and multiply it by 1.08.
I believe it would be related to INSERT TO, so I tried
INSERT INTO table (PricingEUR)
VALUES (PricingUSD*1.08);
Also tried many variations based on tutorials but none worked. Thoughts?
My question is about comparison of fields based on the mapping table SQL Server. In the attached image, I wanted to compare values of Table 1 and Table 2 based on the mapping provided in Table 3. For example, we need to check values of Table 1's Field 1 with Table 2's Field_3_New and other columns likewise. Mapping of these columns to compare is placed in Table 3.
I want to check, whether Table 1's Field 1 values are matching with Table 2's Field 3_NEW's values or not. We came to know that Table 1's Field 1 values have a match with Table 2's Field 3_New values based on the field mapping provided in Table 3. The above is an example scenario, I'm dealing with 40 odd fields like this.
I have a scenario as described below need to create a SSIS Package for that.
I have 3 COLUMNS in source table which needs to be entered in destination table.
But all these columns has to be looked up in the look up table of destination database and then enter their ID's in the destination column.
For example
Source table has 3 columns with values
idnum static type timedimension geography modified date
1 price daydate france 8/12/2015
2 RetailpRICE WEEK ITALY 9/12/2014
I want a package which looks up the column values with the matchin ID and populates in the destination table...
I know we can use the LOOKUP transform to update the data for one single column in destination table what about the other columns which I need to insert along with the lookup insertion.
How can I achieve this ? Also is there a way to pull only the recent data from the source table using modified date column values
Use a different lookup for each lookup table that you need to reference to get the Ids. So if each of your columns that you want IDs for gets its ID from a different table, then you need to use three lookups, one after the other, until you have all three IDs.
Below i have a table where i need to get fields from one column to three columns.
This is how i would like the data to end up
Column1
Music
Column2
com.sec.android.app.music
Column3
com.sec.android.app.music.MusicActionTabActivity
Give the table a numeric autonumber id
Remove the rows with no data with a select where blank spaces or null
Find records with no point in the content with a select
Use the previous query as a source and use the id to find the id + 1 to find the next record and do the same with + 2 to find the second row
Build a table to hold the new structure and use the query as a source to insert the new created data in the new table with the 3 columns structure.
This is an example using sql server
Test table design
Data in table
Query
Look at the query from the inside. The first query inside clean the null records. Then the second query find the records with out point. This records are the reference to find the related two records. Then the id of the records with out point are used to make a query in the select adding 1 for the next record and then other query adding 2 to find the other record. Now you only need to create a table to insert this data, using this query as the source.
Heres the situation. I have 2 tables here of the schema:
ID | COMPANY_NAME | DESC | CONTACT
ID | COMPANY_ID | X_COORDINATE | Y_COORDINATE
The first tabel contains a list of companies and the second contacts coordinates of the companies as mentioned.
The thing is that I want to merge the data in this table with the data in another set of tables which already have data. The other tables have similar structure but are already propopulated with data. The IDs are autoincremental.
SO if we have lets say companies marked 1-1000 in table1 and companies marked 1-500 in table 2. We need it merged such that ID number 1 in table 2 becomes ID 1001 when migrated to the other table. And side by side we would also want to migrated the entries in the coordinates table as well in such a way that they map with the new ids of the table. Can this be done in SQL or do I need to resort to using a script here for this kind of work.
i`m not sure i understand how many tables are there and who is table 1 ,2, but the problem is pretty clear. i think the easy way is:
back up all your database before you start this process
add a column to the destination table that will contain the original id.
insert all the records you want to merge (source) into the destination table, putting the original id in the column you added.
now you can update the geo X,Y data using the old ID
after all is done and good you can remove the original id column.
EDIT: in reply to your comment , i`ll add teh code here, since its more readable.
adapted from SQL Books Online: insert rows from another table
INSERT INTO MyNewTable (TheOriginalID, Desc)
SELECT ID, Desc
FROM OldTable;
Then you can do an update to the new table based on values from the old table like so:
UPDATE MyNewTable SET X = oldTable.X , Y = oldTable.Y where
FROM MYNewTable inner JOIN OldTable ON MYNewTable.TheOriginalID = OldTable.ID
