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.

MS Access - trying to find duplicates across 4 tables based on the info in Column1 and Column2. I would also like the resulting query to show me Column3, Column4 and Column5 for easy review. I've tried following a Youtube vid on a union query and was successful.. But that's as far as I can go. I tried to follow along some of the answers but I cant make it work. Just note that I have 0 programming language knowledge. Tyvm in advance!
Column1 = Unique reference
Column 2 = Loss date
Duplicates happen when a row has same unique ref and same DOL. This can be within the table or across tables. Like one entry is in Table2019 and another one is in Table2022. Or two entries in Table2019 with four more spread in other tables.
SELECT [t2019].ID, [t2019].[ClaimNo], [t2019].DOL, [t2019].[Amount], [t2019].[Cause], [t2019].[Ref], [t2019].[Regn], [t2019].Remarks
FROM [t2019]
UNION
SELECT [t2020].ID, [t2020].[ClaimNo], [t2020].DOL, [t2020].[Amount], [t2020].[Cause], [t2020].[Ref], [t2020].[Regn], [t2020].Remarks
FROM [t2020]
UNION
SELECT [t2021].ID, [t2021].[ClaimNo], [t2021].DOL, [t2021].[Amount], [t2021].[Cause], [t2021].[Ref], [t2021].[Regn], [t2021].Remarks
FROM [t2021]
UNION
SELECT [t2022].ID, [t2022].[ClaimNo], [t2022].DOL, [t2022].[Amount], [t2022].[Cause], [t2022].[Ref], [t2022].[Regn], [t2022].Remarks
FROM [t2022];
Access has a wizard to help write the relatively difficult SQL for finding duplicate records. So first gather up all the records that need to be searched for duplicates then use the wizard.
To gather the records open the query designer, go to the SQL Pane, SELECT union and adapt the following SQL:
Unfortunately, there is no graphical interface to help.
Get Typing and don't forget that semi-colon. UNION is used to combine SELECT statements. So were combining everything from all the tables. the ALL is important because by itself UNION ignores rows where every column is an exact match to a previous row. We are looking for duplicates so we add ALL to include those skipped rows.
When you have all the rows go to query wizard under the create tab and run the find duplicates wizard:
Here is the resulting SQL for my example data:
SELECT Query1.[ID], Query1.[DOL], Query1.[ClaimNo], Query1.[Amount], Query1.[Cause], Query1.[Ref], Query1.[Regn], Query1.[Remarks]
FROM Query1
WHERE (((Query1.[ID]) In (SELECT [ID] FROM [Query1] As Tmp GROUP BY [ID],[DOL] HAVING Count(*)>1 And [DOL] = [Query1].[DOL])))
ORDER BY Query1.[ID], Query1.[DOL]
Note:
In Access ID is a primary key and AutoNumber by default. It looks suspicious here. If the default settings are intact and you are entering data in Access then every table starts with ID 1 and you have duplicate ID's in every table. Instead, I would normally combine all these year tables using a year column. This also avoids the union query. I would only use year tables if I had millions of records and couldn't afford the space for a year column.
I have this newly created table in SQL Server with 3 columns ID, Name, Source.
Basically this table will be populated with data from other different tables, each specifically taking in their record IDs and record Names. I believe this can be easily achieved with an INSERT INTO SELECT statement.
I would like to find out on how to populate the Source column. This column is supposed to indicate which table the data came from. For example, Source in table A has 3 records, which I then copied the ID and Name columns from this table, and put it into my destination table.
At the same time, the 3 new records will have their Source column set, indicating it came from Table A. Then I will proceed to do the same for other tables.
You can use the constant string as follows:
INSERT INTO your_table
SELECT id, name, 'TableA' as source
FROM tableA
I have a database table which constantly gets updated. I am looking to query only the changes/additions that have been made on rows with a specific attribute in a column. e.g. get the rows which have been changed/added, the 'description' column of which is "xyz". My end goal is to copy these rows to another table in another database. Is this even possible? The reason for not just querying and overwriting the rows in the other database is to avoid inefficiency.
What I have tried so far?
I am able to select query on the table to get the rows but it gives me all the rows, not the ones that have been changed or recently added. If i add these rows to the table in the other database, the only option I have is to overwrite the rows.
Log table logs the changes in a table but I can't put additional filters in SQL which tells me which of these changes are associated with 'description' column as 'xyz'.
Write your update statements to make use of OUTPUT to capture the before and after values and log them to a table of your choice.
Here is a really simple example update example that uses output to store the RowID, before and after values for the ActivityType column:
DECLARE #MyTableVar table (
SummaryBefore nvarchar(max),
SummaryAfter nvarchar(max),
RowID int
);
update DBA.dbo.dtest set ActivityType = 3
OUTPUT deleted.ActivityType,
inserted.ActivityType,
inserted.RowID
INTO #MyTableVar
select * From #MyTableVar
You can do it two ways
Have new date fields/columns like update_time and/or create_time(Can be defaulted if needed). These fields will indicate the status of the record. You need to save your previous_run_time and then your select query will look for records with update_time/create_time greater than previous_run_time, and then you can move these records to the new DB.
Have CDC turned on the source table, which is available by default in SQL server and then move only those records that have been impacted.
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.
i'm trying to keep a record of which customers have received which newsletters. I have a query called
TempQuery
I want to take the field
TempQuery.CustID
That consists of several numerical id's and combine it with two static values specified on a form
Forms![frmAddCorrespondence]![txtNID]
Forms![frmAddCorrespondence]![txtDate]
such that I end up with something like
CustID NID Date
1 5 28/03/2011
3 5 28/03/2011
14 5 28/03/2011
56 5 28/03/2011
Again the fields NID and Date will be the same values for each individual insert specified on frmAddCorrespondence and the CustID's are pulled from TempQuery.
I'd like this to be a query from which the data can be inserted into a log table of all our past correspondences.
Any help is greatly appreciated
Thanks, Rob
you want a full outer join between your temp query and the date and ID entered at runtime?
If so, you can pass the two new column values (ID and date) as parameters to your query. Just create a new query based on your existing one and add the two control references as new columns.
Is that what you wanted?
In response to your comment, yes, you can create a second append query in Access that takes all the columns from your query and adds the two parameters from the controls on your form.
