from dbo.R_ResrvStock inner join Txt_Temp on Right (dbo.R_ResrvStock.Vin,6)=Txt_Temp.VinNumber

Data Comparison
Jul 23, 2005I have an Employee table with 3000 records and an Excel file having themodified data of those emplyoees. Some of the data of Excel may be sameas that of table data but some may differ. EmpId is the unique field.Other than this field, other fields of Excel may have modified data.Ineed to compare the data from SQL Server table with Excel Data.I decided to write a VB Program having two recordsets,one for SQLServer and other for Excel and compare each field's value. If themodified value is found then update that to table. Is there any way tocompare in SQL Server itself?Madhivanan

Jan 23, 2003Hi,
Short version:
How would you accomplish comparing ALL the values in two tables wherein the PKs for each table are identical?
Long version:
SQL Server 2000 database with two tables
of identical structure having rows with some new data, some old data.* It's easy to determine which rows are 100% new by
looking for PKs not in the old data.
For the remaining rows, I need to make
certain no rows have been modified.
* Actually, there are hundreds of
pairs of tables as described.
The data comes from flat files, and I'd
rather use the database than Perl in this
case.
I can write code to generate the
list of columns for each table and then
query these as sets. Is there any
other method that might work better?
Data Comparison Question
Mar 21, 2006I am not sure if this is the correct forum for my question but I will give it a shot. I want to be able to create a dataset from an ODBC datasource and compare it to existing data in my SQL DB. If there are changes (inserts/updates/deletes) I want to raise seperate events for each row state. Is this possible to do with SSIS/DTS or am I on the wrong track with what I am trying to do?

SQL 2012 :: Ignore ANSI Characters In Data Comparison?
Aug 18, 2014I am comparing two fields one from our legacy table and one in our new table structure that should have identical text data. The new field has an assortment of ANSI characters where the legacy data did not have these. Is there anything I can do that will ignore all ansi character differences? The only route I can think of is just do a replace on each ANSI type on the new column but there are quite a few character types.

Aug 6, 2015I want to make data changes in read_only database , that's why i must set database read_write. While database is at read_write mode, i want to be sure that no one makes change in database.
For this aim, i write the code below, but i suspect that after setting the database read_write, till the setting database
single_user ,is it possible get DML script from another user. Is the code below enough for this operation. Or is there another way?
Reminding: Read_only database can not be set single_user mode. That's why, first you must set database read_write.
The code;
use master
alter database xxx set read_write
with rollback immediate
alter database xxx set single_user
with rollback immediate
use xxx
update tablexxx set columnxxx=yyy
use master
alter database xxx set read_only
with rollback immediate
alter database xxx set multi_user
with rollback immediate

SQL Date Comparison
Jun 27, 2000Hi...
I have a problem comparing dates in SQL Server 7.
I want to find results where date1 = date2.
I am having problems becausing SQL is also trying to compare the time which
is included in the field value e.g. 03/04/00 12:01:32
So even if the dates are equal the time may be different so the results are not shown?
I've tried SUBSTRING, and CONVERT,CAST etc.. and still can't get it to work
Any ideas???
Thanks.

Date Value Comparison
Oct 23, 2003Good day,
I am receiving garbage data from my other department as follows.
I want:
'12/05/03' for example.
I get:
'//'
'00/00/00'
And other garbage. All of which crashes the transaction because it cannot be converted to Datetime.
What I would like to do is something like this:
IF @v_date > '01/01/50'
BEGIN <-- statement will crash if bad data)
Something to trigger a Boolean (True/False) validation of the data.
I want to know if it is even a date before I run it through my block.
Any thoughts?
I don't want to add a new IF block for every bizarre thing they send me.
Thanks ahead of time.
PS - I guess I could just raise an exception and handle it in a block that way, but am still curious.
Comparison Between Columns.
Dec 11, 1998Hi friends,
How can I do, in one Trigger, to returns if two columns, one of the Inserted and other of the Deleted, are differents ? I used this example:
If ( select Name from inserted ) !=
( select Name from deleted )
Insert Into Log_System
( Key_Mame, User_Name, Date, Field, Value, Table_Name )
Select 'COD. PROD: ' + Convert( char(10), I.Cod_Prod ),
SUSER_NAME(), GetDate(),
'Name', Convert(Char(255), D.Name ),
Convert(Char(255), I.Name), 'U', 'PRODUCTS'
From Inserted I, Deleted D
But, if one of them is Null, then the comparison result returns FALSE.
Examples:
1 - If in the Table are keeped null and the new value is different of Null
the comparison result returns FALSE.
2 - If in the Table are keeped a value and the new value is null the
comparison result returns FALSE too.
Excuse me, my English is not currently.
Thanks !
Rodney.
String Comparison
May 15, 2001Hi,
Assuming a table with a column defined char or varchar.
I have a SQL query like this :
Select * from table1 where column1='Building'
It returns the same result that
Select * from table1 where column1='BUILDING'
It is my understanding SQL Server (verison 7 or 2000, I tried on both) is lower/capital insensitive by default when it is installed. If I want SQL Server to be case-sensitive with my char or varchar columns, where can I set it?
Is it at database level or server level I can find this setting . What is the setting that control it?

Like Comparison Problems
Jan 12, 2006Hello im trying to run a simple query where i compare something simple like BEARING to a field in the database using this query.
Code:
SELECT table1.STK_NO, table1.STK_NO2
FROM table1
WHERE (LEN(CLEANSED_REF)>2)
AND ('BEARING' LIKE '%'+table1.CLEANSED_REF+'%')
Inside the table i can see the CLEANSED_REF field and its value is "000BEARINGBRNG000". When i run the query i get no records returned.
But if i run
Code:
SELECT table1.STK_NO, table1.STK_NO2
FROM table1
WHERE (LEN(CLEANSED_REF)>2)
AND (table1.CLEANSED_REF LIKE '%BEARING%')
The query returns the row i wanted. Can anyone tell me why this wont work the first way, but works the second?

Date Comparison
Dec 28, 2005I have two tables that I am needing to link by the tables date field. In one table the date field is defined as varchar(23). The time for this field is always zeros.
Example: '2005-12-27 00:00:00.000'
The other table is defined as datetime, and it does have the date and time in this field.
Example: 2005-12-27 08:00:35.000
The problem i am having is
2005-12-27 00:00:00.000 does not = 2005-12-27 08:00:35.000.
Because I will never have more than one record on the same date I would like to be able to only compare the date. Example 2005-12-27 = 2005-12-27
Since the fields are 2 different field types, this is giving me a problem. Could someone please help. I have tried everything I know to do.
What I really need is the a way to format the datetime fields date into a string such as '2005-12-27'.
Hopefully what i have written makes sense.
Thanks
Database Comparison
Oct 4, 2006I had an application go down yesterday...it was giving a Type Mismatch error and the support team couldn't figure it out.
My suspicion is that a field in the database got populated with a character the vb app didn't like when it renders the information.
I'd like to prove that theory...but the database is large (4gb) and I'm not sure how to do a database comparison to see where the records differ.
Anybody have a script to get me started OR some experience to share?
Thanks,

Comparison Of 2 Tables
Jul 13, 2013I am doing this 2 queries, they get data from the same tables in a very different way. The new way is a lot faster but of course there are problems. There are some discrepancies in the results. Both queries produce results with more than 200.000 rows. Second one has ca. 100 rows less than the first one and some of the results are wrong (most are correct though).
My question is how do I find the differences. I did the left outer join when column a.result != b.result (lines are defined by date and ID so they should be unique).but the join gives me problematic results (some are not different at all, some differences are not in the result).so how do I find the differences between 2 queries, including missing results/rows?
