In Snowflake how to access last accessed/last modified data for each column in a table? Like if we want to have a range of 7 day period then how to get those details.

To set this up....I have roughly 12,000 rows of data that captures sales detail activity. I have an Excel function in a column to the right of the data that identifies the invoice number based on unique qualifiers (if the transcation meets the qualifier it lists the invoice number and, if not, assigns ""). Of the 12,000 rows of data maybe 50 will qualify. I then need to use the invoice numbers that qualify to pull sales and COGS data for all those invoices that match the qualifying invoice numbers (another explanation is necessary at this point....an invoice that qualifies will be listed twice....once that contains the information that identifies whetehr it qualifies but that row will have no sales data and a second time with thye dsales data...I do not know why it does it this way. So, in other words, the row of data with the sales information I need to capture does not contain the data that allows me to recognize that an invoice qualifies). Each mopnth adds the current month's sales data to the population...so, 12,000 rows this month and it will be 16,000 next month and so on.
I was hoping to create a table that pulls only the qualifuying invoice numbers from the sales data (it would basically create a table of 50 (in my example) while ignoring the 11,950 rows where the cell equals ""). I can do a simple pivot table but next month I need it to recognize the new population of data and update based on the additional rows of new monthly data as well as the rows of data from prior months.
Any soultions/ideas are much appreciated!
I have 2 different datasets. one for current month and another one for previous months data. I want to compare the data under a single SSRS table. The SSRS table has column and row groups. How can I relate it and get a combined report from those datasets. Please help.
If you are not using cumulative data, have you looked at using LookUp?

I am an application programmer but currently I have a situation in which I need to copy a huge amount of data which is collected for 1 month say approx 653 GB of data from the table in one database to exact similar table in other database (both oracle 11G). Each row size is approx 150 bytes. So the number of rows are approximately 4000 millions. I am not joking.
I have to do this. The table which holds this data (source table) is partitioned based on date column. So there is a partition for each day of the month and hence in total 31 partitions for December month.
The target db is partitioned based on month. So there is a single partition in the target db for complete december month.
I have chosen to copy the data over db link and with the help of dba's I created a db link between this 2 databases.
I have a store procedure in target db which accepts input parameter as (date, tablename). What this procedure does is it creates a temporary table in target db with name as tablename and copies all the data from the source db for the given date into this temporary table in target database. I have done it successfully for 2-3 days. Now I want to insert this data in the temporary table into actual table in the same target database. For that I executed following query:
insert into schemaname.target_table select * from schemaname.temp_table;
But I am getting folloowing ORA error.
ORA-01858: a non-numeric character was found where a numeric was expected
Both the tables have exact same table defination. I searched over internet for copying data and found the above query to insert as simplest. But I don't understand the error. Searching for this errors show it is has something to do with date column. But shouldn't it work as both the tables have same table structure?
Data types used in the table are varchar2(x), date, number(x,y), char(x).
Please help me to get over this error. Let me know if any other information is required.
It means your schemaname.temp_table table has some non-numeric value which doesn't inserted in your new table. Did schemaname.temp_table table populated with some script or any automated tool? There is possibility of empty space or junk character inserted in schemaname.temp_table. Kindly check once again using any sql tool.
I have table with
fields: Id, ChId, ChValue, ChLoggingDate
Now the data will be saved for everyminute in to the database. I need a query to check if the data exists for every minute in the table through out the year for a particular weekday. That is, all Monday's in 2013 if it has complete data for that day calculate the arithmetic mean for the year of Monday's.
YOu will need a table - or a table value function - to create a timestamp for every minute, then you can join with that and check where the original table has no data.
Only way - any query otherwise can only work with the data it has.
This is a common approach for any reporting.

explains how, you just must expand it to a times table. If you separate date and time you can get away with a time table (00:00:00 to 24:59:59) and a date table separately.
I have a table X_Data where some data is saved based on Itemcodes. I have another table Item_Master where the item details are stored. In both tables there is a column called leadtime. But in table X_Data, it gets updated by some stored procedure calculations.
For certain condition, I need this data to be refreshed with the one I have in Item_Master table. I don't want to include any loop or stored procedure for this.
Is it possible to update the data in X_Data table for all items using a single query?
