I have a column with numbers and I need to find the difference of that from 10 and insert all the values in parallel in a different column. Can anyone tell me how to get this data into a new column under the name "10-data" and update the same table?

Hi I have a table with all numeric values inserted in column 1, column 2, column 3.....
I know how to find the most repeated two values from one column but our goal is to find the most repeated two from all tables. Could you help provide any quicker thoughts?
I have a table which contains columns with multiple values(comma separated).How to fetch data based on a single value from these columns.Using mysql as DBMS
So, I have a table which has 3 columns.
Customer_number, login_hash and some_hash
The customer_number is not the auto increment id and the table is being indexed on login_hash.
Now the table is updated every hour and new entries are being added. I have to get the new entries, use them for some calls and then store the resulting data.
My plan is to always store the last row number in some last_row environment variable and then retrieve values after that row number till the last record. Then update the last_row number.
How do I achieve this? And is there any better approach to this problem?
I know this is a bad table design but I have to deal with this and can't change it.
I have a table with 50 columns, and the table has more than one lakh records.
My requirement is to get few desired records from the table and insert into another machine's database table.
Is there a way to extract the desired result records along with Insert statement? I tried doing with exporting the data, but it fetches all the records.
Any suggestions please?
what if I wanted to update the records in the table by altering values in one of the columns?
I have records in the table that have one column empty(null values). I want to change these values and insert values from another table into those records.
Basically I have a table with one column empty. I do not want to append to the end of the table but start inserting from record 1.
For the existing records, you would have to use UPDATE to update that one column, WHERE thatColumn IS NULL.
Shouldn't the values in that column have some relation to the rest of the record? I could understand initializing the existing records to a non-null value, or using an UPDATE query to populate data from another table in that column, but all related to the original row...
UPDATE old SET old.badColumn = new.newData
FROM oldTable old
JOIN newTable new on old.someID = new.someID
This would find the related data in newTable matching oldTable, and update the badColumn to some data from newTable... let me know if you need more help.
See the "Using the UPDATE statement with information from another table" section from this page of SQL Server Books Online.
