In this example, the sale is record in year 2014 and month 10, but there are revenues in every month as well for the rest of 2014 and the start of 2015 but we only want to the sales amount to appear once on this results set.

Insert, Update && Delete On Two Tables With Same Data Structure...
Jun 30, 2006I have created two table with same data structure. I need realtime effects (i.e. data) on both tables - Table1 & Table2.
Following Points to Consider.
1. Both tables are in the same database.
2. Table1 is using for data entry & I wants the same data in the Table2.
3. If any row insert, update & delete occers on Table1, the same effect should be done on Table2.
4. I need real time data insert, update & delete on Table2.
I knew that using triggers it could be possible, I have successfully created a trigger for inserting new rows (using logical table "Inserted") in Table2 but not succeed for update & delete yet.
I want to understand how can I impletement this successfully without any ambiguity.
I have attached data structure for tables. Thanx...

How To Delete Rows From Multiple Tables In SQL
Oct 23, 2007I have an SQL 2000 server. I have multiple tables in the db that have a row with a time stamp of '10-23-2007'. What I am trying to do is delete these specific rows because they don't belong.
So I need to query the db for table names that are like 'elect_Sub%' and then execute a query on those tables that would delete the row with the time_stamp '10-23-2007'. I know that I have to use the db schema to get the table names, but I need help in writing the sql script that will automatically scroll through the tables.
Thanks,
Delete Rows With Duplicate Column Data But Unique Row Data
May 25, 2000Hello,
This probably has been addressed before but I was unable to get the search to work properly on this site.
I am needing a script/way of deleting all rows from a DB with the exception of one record left for each row that has duplicate column data. Example :
Row 1
Field1 = 12345 Field2 =xxxxx Field 3=yyyyy Field4=zzzzz etc.
Row 2
Field1 = 12345 Field2 =zzzzzz Field 3=xxxxxx Field4=yyyyyy etc.
Row3
Field1 = 12345 Field2 =20202 Field 3=11111 Field4=zzzzz etc.
Row 4
Field1 = 54321 Field2 =xxxxx Field 3=yyyyy Field4=zzzzz etc.
Etc. Etc.
I want to be able to find the duplicates for Field1 and then delete all but 1 of those rows.( I don't care which one I keep just so only one is left.) The data in the other fields may or may not be unique.
I know how to find the duplicates it's just the deleting part I am having problems with. Any help would be much appreciated. Thanks,
Kerry
