I run the script below once a day to keep track of row count over time. I would like to compare the results from today and yesterday to see if anyone deleted more than 20% of data from any given table. How would I do this? I really don't need the data anymore than a day just to compare the results.
Mon - Run script to collect row count
Tues - Run script to collect current row into temp table
,compare all row count in both tables
,purge records from Monday and insert current
Wed - Run script to collect current row into temp table
,compare all row count in both tables
[code]....

I have one database with several tables in it (table 1, table2, table3). In each table is two colums (colum1 = a number (201220) and colum2 = a number (0.50). Now, both tables will have rows with the same data in colum 1, but colum two will have different numbers (different prices). My goal is to run a query that will compare both colums in all three tables, take the lower of the three based on colum 2 and spit out the row. Obviously, this would output all rows (around 175k). The point is to create a least cost spreadsheet (csv) file based on evaluating all three tables.

I'm not a full-time DBA, so excuse my style of expressing my question.I have a database which has 2 tables in SQL 2005. Both these tables have similar column names, EXCEPT for new extra columns in FY2007_DATA. I can visually see the difference in columns in Database Diagrams. My goal is to :- I want to compare FY2007 tbl column names to FY2006 column names and display only those columns as results that do not match.Tbl 1 :- FY2006_DATA Tbl 2:-
FY2007_DATA
With online reading and help I have managed to get this script to do exactly opposite of what i want. Below is the query
/* This query compares the column names from two tables and displays the ones that have an exact match. It does not care for case-sensitiveness */
Select a.Table_Name, a.Column_Name, (b.Table_Name), (b.column_name)
From [2006-2011].INFORMATION_SCHEMA.Columns AS a
Join [2006-2011].INFORMATION_SCHEMA.Columns AS b on a.Column_Name = b.Column_Name
Where a.TABLE_NAME = 'FY2006_DATA'
And b.TABLE_NAME = 'FY2007_DATA'
AND a.Column_Name IN
(Select Column_Name = LEFT(c.column_name, 20) FROM
[H1B_2006-2011].INFORMATION_SCHEMA.Columns AS c WHERE c.TABLE_NAME = 'FY2007_DATA' )
When I change "AND a.Column_Name IN.." to "AND a.Column_Name NOT IN.." so that the results will (should) display the extra columns in FY2007, in fact I do not see any results, but query executes perfect.
How can I achieve my goal.?
Thank you

I have a database project where objects have been pulled in from the database using schema compare.
Unfortunately CDC tables which are referenced in stored procedures on the database have not been pulled in by the schema compare & hence I cannot build the project and deploy changes back to the database.
How to get these tables included in the project .

I'm rewriting a huge FOR XML EXPLICIT procedure to use FOR XML PATH, and need to compare previous output to the refactored one, so i didn't mess up XML structure.
The thing is, i'm not sure that SQL Server will always generate exactly same xml **string**, so i'd rather not compare by:
WHERE CAST(@xml_old AS NVARCHAR(MAX)) = CAST(@xml_new AS NVARCHAR(MAX))
nor do i want to manually validate every node, since the generated xml-structure is quite complex.
compare xmls by their "semantic value" ?

how would I compare a list of concrete values?
---table with items
SET NOCOUNT ON;
DECLARE @items TABLE (ITEM_ID INT, ITEM_NAME VARCHAR(10))
INSERT INTO @items (ITEM_ID, ITEM_NAME) SELECT 10,'ITEM 1'
INSERT INTO @items (ITEM_ID, ITEM_NAME) SELECT 11,'ITEM 2'
INSERT INTO @items (ITEM_ID, ITEM_NAME) SELECT 12,'ITEM 3'
INSERT INTO @items (ITEM_ID, ITEM_NAME) SELECT 13,'ITEM 4'
INSERT INTO @items (ITEM_ID, ITEM_NAME) SELECT 14,'ITEM 5'
INSERT INTO @items (ITEM_ID, ITEM_NAME) SELECT 15,'ITEM 6'
INSERT INTO @items (ITEM_ID, ITEM_NAME) SELECT 16,'ITEM 7'
INSERT INTO @items (ITEM_ID, ITEM_NAME) SELECT 17,'ITEM 8'
SELECT * FROM @items
-- table with categories
SET NOCOUNT ON;
DECLARE @categories TABLE (CAT_ID INT, CAT_NAME VARCHAR(10))
INSERT INTO @categories (CAT_ID, CAT_NAME) SELECT 100,'WHITE'
INSERT INTO @categories (CAT_ID, CAT_NAME) SELECT 101,'BLACK'
INSERT INTO @categories (CAT_ID, CAT_NAME) SELECT 102,'BLUE'
INSERT INTO @categories (CAT_ID, CAT_NAME) SELECT 103,'GREEN'
INSERT INTO @categories (CAT_ID, CAT_NAME) SELECT 104,'YELLOW'
INSERT INTO @categories (CAT_ID, CAT_NAME) SELECT 105,'CIRCLE'
INSERT INTO @categories (CAT_ID, CAT_NAME) SELECT 106,'SQUARE'
INSERT INTO @categories (CAT_ID, CAT_NAME) SELECT 107,'TRIANGLE'
SELECT * FROM @categories
--table where categories are assigned to master categories
SET NOCOUNT ON;
DECLARE @master_categories TABLE (MASTERCAT_ID INT, CAT_ID INT)
INSERT INTO @master_categories (MASTERCAT_ID, CAT_ID) SELECT 1,100
INSERT INTO @master_categories (MASTERCAT_ID, CAT_ID) SELECT 1,101
INSERT INTO @master_categories (MASTERCAT_ID, CAT_ID) SELECT 1,102
INSERT INTO @master_categories (MASTERCAT_ID, CAT_ID) SELECT 1,103
INSERT INTO @master_categories (MASTERCAT_ID, CAT_ID) SELECT 1,104
INSERT INTO @master_categories (MASTERCAT_ID, CAT_ID) SELECT 2,105
INSERT INTO @master_categories (MASTERCAT_ID, CAT_ID) SELECT 2,106
INSERT INTO @master_categories (MASTERCAT_ID, CAT_ID) SELECT 2,107
SELECT * FROM @master_categories
-- items-categories assignment table
SET NOCOUNT ON;
DECLARE @item_categories TABLE (CAT_ID INT, ITEM_ID INT)
INSERT INTO @item_categories (CAT_ID, ITEM_ID) SELECT 100,10
INSERT INTO @item_categories (CAT_ID, ITEM_ID) SELECT 105,10
INSERT INTO @item_categories (CAT_ID, ITEM_ID) SELECT 100,11
INSERT INTO @item_categories (CAT_ID, ITEM_ID) SELECT 105,11
[code]....
So now I need to query the table @t4 in and to determine the items that are assigned to category 'WHITE' in master category 1 and to 'CIRCLE' in master category 2.The important thing is to return items that are assigned solely to 'WHITE' in master cat 1 and solely to 'CIRCLE' in master cat 2.In the above example it would be only the ITEM 1 (id=10) that is returned:
1. ITEM 2 (id=11) is not returned because it has the assignment to category 'SQUARE' in master cat 2 additionally
2. ITEM 3 (id=12) is not returned because it has the assignment to category 'BLACK' in master cat 1 additionally
3. ITEM 4 (id=13) is not returned as it does not have assignment to category 'CIRCLE' in master cat 2 but only to 'WHITE' in master cat 1
3. ITEM 5 (id=14) is not returned as it does not have assignment to category 'WHITE' in master cat 1 but only to 'CIRCLE' in master cat 2

Is there a efficient way to compare two different columns of 2 different rows in a data set as shown below.
For eg: I would like to DateDiff between Date2 of RowID 1 and Date1 of RowID 2 of IDNo 123. After this comparision , if datediff between two dates are <=14 then i want to update 1 else 0 in IsDateDiffLess14 of RowID1 . In below example its 0 because datediff of two dates >=14. So, want to compare the Date2 and Date1 in this sequence for the same IDNo. For RowID 6 there is only 1 row and no other row to compare, in this case IsDateDiffLess14 should be updated with 0.
RowID IDNo Date1 Date2 IsDateDiffLess14
1 123 04/10/2013 04/12/2013 0
2 123 05/10/2013 05/11/2013 1
3 123 05/21/2013 05/25/2013 0
4 112 01/10/2013 01/14/2013 1
5 112 01/27/2013 01/28/2013 0
6 120 03/10/2013 03/12/2013 0

What I need to be able to find is any records where the Discontinue_Date is greater than the Effective_Date on the next row for a given Customer ID and Part_ID. This is a customer pricing table so the Discontinue_Date of row 53 for example should never be greater than the Effective_Date of row 54130, these are the records I'm looking to find. So I'm looking for a SELECT query that would look for any records where this is true. Obviously the last Discontinue_Date row for a Customer_ID will not have a next row so I wouldn't want to return that.

I am in process to develop TSql code to identify change in data.
I read about Binary_checksum and hashbyte. Some people say hashbyte is better than binay_checksum as chances of collision are less.
But if we may consider following, chances exist in hashbyte too. My question is what is the best way to compare data to identify change (I can't configure CDC) ?
select HASHBYTES('SHA','121'+'34'), HASHBYTES('SHA','12'+'134'),BINARY_CHECKSUM('121','34'),BINARY_CHECKSUM('12','134');

I am trying to write a function to compare the characters between 2 strings and eliminate the similarities to be able to return at the end the number of differences between them.
Having in mind i need the bigger number of differences to be returned also if a character is repeated in one of the 2 words it will be eliminated once because it exist only one time in other string.
I will give an example below to be more clear
--Start
declare @string1 as varchar(50)='imos'
declare @string2 as varchar(50)='nasos';
WITH n (n) AS (
SELECT 1 FROM (VALUES (1),(1),(1),(1),(1),(1),(1),(1),(1),(1)) n (n)
[Code] ....
The differences in first string from second one are 2 (i,m) while the differences in second string from first one are 3(nas).
So the function should return 3 in previous example.

Say you have a table that has records with numbers sort of like lottery winning numbers, say:
TableWinners
num1, num2, num3, num4, num5, num6
33 52 47 23 17 28
... more records with similar structure.
Then you have another table with chosen numbers, same structure as above, TableGuesses.
How could you do the following comparisons between TableGuesses and TableWinners:
1. Compare a single record in TableGuesses to a single record in TableWinners to get a count of the number of numbers that match (kind of a typical lottery type of thing).
2. Compare a single record in TableGuessess to ALL records in TableWinners to see which record in TableWinners is the closest match to the selected record in TableGuesses.

I have a student table like this studentid, schoolID, previousschoolid, gradelevel.
I would like to load this table every day from student system.
During the year, the student could change schoolid, whenever there is a change, I would put current records schoolid to the previous schoolid column, and set the schoolid as the newschoolid from student system.
My question in my merge statement something like below
Merge into student st
using (select * from InputStudent ins)
on st.id=ins.studentid
When matched then update
set st.schoolid=ins.schoolid
, st.previouschoolid= case when (st.schoolid<>ins.schoolid) then st.schoolid
else st.previouschoolid
end
, st.grade_level=ins.grade_level
;
My question is since schoolid is et at the first line of set statement, will the second line still catch what is the previous schoolid?

I have two the same structure tables. One is the source table (table1), another one is the destination table (table2).
Now I want to compare these two table row by row.
For example,
If table1 row1 is the same as table2 row1, go to next
If table1 row2 is not the same as table2 row2, update table2 row2 to make it the same as table1 row2.
If table1 row3 is not existed in table2 row3, insert table1 row3 into table2 blank new row.

I have 2 tables that are exactally the same.
Table 1 - Is named LIVE
Table 2 - Is name EOM (End of Month)
The 2 tables have these fields
MEMBER
STREET
I want to build a query that will return any member who has changed their address (ex: member's eom address is "123 main st", and now their live address is "345 apple st")
But I do not want to display any addresses that are different because that member wasn't a member last month (not in the eom table)
Note: Member Numbers Never Change, only addresses will.
Thanks in advance for any help/suggestions.
