Comparing 2 Similar Columns In Different Tables
Mar 5, 2014
I am trying to write an SQL command for my crystal report. I need to compare the same column in 3different tables & get the data from each table for only the matching data.. I understand I need to create a temporary table, get the data into it & then work around.. I am quite new to SQL.
Eg: Considering one customer account
Table 1
Cust.No Name Amt_Counter AmtPaid
123.456 sam 0 0
123.456 sam 1 50
Table 2
Cust.No Name Freq_Counter Frequency
123.456 sam 1 0
123.456 sam 2 15
[code]....

It seems that there should be a solution for my situation, but for the life of me I can't seem to figure it out.
I need to compare two "like" tables, containing similar data. Tbl 1 is "BOOKED" (which is a snapshot of inventory) and tbl 2 is "CURRENT" (the live - working inventory table). If I write my query as follows the the subsequent result is "duplicate" data.
Code Block
SELECT booked.item, booked.bin, booked.quantity, current.bin, current.quantity
FROM BOOKED
LEFT JOIN
CURRENT
ON booked.item = current.item
No matter what type of join I use, there is duplicate data displayed for each table. For example, if there are more bins in the BOOKED table that contain a certain product then the CURRENT table will repeat data and vica versa.
As follows:
Item
Bin
Quantity
Bin
Quantity
12345
A01
500
A01
7680
12345
B01
6
A01
7680
12345
C01
20
A01
7680
54321
G10
1032
E15
1163
54321
G10
1032
F20
523
54321
G10
1032
H30
750
98765
Z20
7000
Z20
8500
98765
Y15
2500
Y15
3000
98765
X10
1200
Y15
3000
What I would like to do is display Bin and Quantity only once and the repeating values as NULL or [BLANK]. Or, to display all of the bins from both tables and only the quantities from each table in relation to the bin found in that table, returning a "0" if no quantity exists.
This is what I'm after:
Item
Bin
Quantity
Bin
Quantity
12345
A01
500
A01
7680
12345
B01
6
B01
0
12345
C01
20
C01
0
54321
G10
1032
E15
1163
54321
F20
0
F20
523

8500
98765
Y15
2500
Y15
3000
98765
X10
1200
X10
0
Is this possible? If so, how?
I also might add that it is ok for each table to contain multiple entries for any given item. This is basically being requested as an inventory variance report - inventory before physical count and immediatly after physical count - and will only be run once a year.
-----------------------------------------------
Just thinking out loud here:
What if I created three subqueries, the first containing only BOOKED information, the second containing only CURRENT information and the third being a UNION of both tables? Something like this:
Code Block
SELECT q3.bin, q1.item, ISNULL(q1.quantity, 0) as QTY_BEFORE, ISNULL(q2.quantity, 0) as QTY_AFTER
FROM
(select item, bin, quantity
from BOOKED)q1
Left Join
(select item, bin, quantity
from CURRENT)q2
on q1.item = q2.item
Left Join
(select bin, item
from BOOKED
UNION
CURRENT)q3
on q1.item = q3.item
Order By q1.item
I don't know if I wrote the UNION statement correctly, but I will have to try this when I get back to work...
Any suggestions?

For every table in my database there is a duplicate table with same columns. For example, employee is the name of main table, there is employee_dup table in same database.
There is only one column extra in _dup tables i.e.,idn column.
Now, I want to know all the columns present in main table which are not present in corresponding _dup table. There might be a chance of missing one or two columns in _dup tables. So i want a query to find out all the columns present in main table that are not present in hx table.

I am using this query to search checkbox values.
SqlCommand cmd = new SqlCommand("Select * from Details where Emp_Code in (" + selectedValues + ")", con);
I want to join a table called Materials to this now. Material table also has an Emp_Code column. How can I write a select sql query to fetch Emp_Code from both Details and Materials table.
SqlCommand cmd = new SqlCommand("select D.Emp_Code, M.Emp_Code from Details D, Materials M where D.Emp_Code = M.Emp_Code in (" + selectedValues + ")", con);

I have a table that I am basically reduplicating a couple of times for each part of this database that I want to create.Each table basically has the same data: The tables will be called motherTable, fatherTable, sonTable, daughterTable and so on.I am pretty much using the following in each column: UserID, MotherID(or FatherID or SonID, etc., etc. and so on for each unique table), FirstName, LastName, MiddleName, BirthPlace, Photo, Age.I don't see an option to copy a table and just modify the second ID part and rename that table accordingly.How can I make this an easier way of creating these similar tables without retyping all these columns over and over again?Thanks in advance.

Hi,I have 2 tables and each has a text column. When i compared the 2columns with the LIKE operator i found something strange.create table test1( var1 text )create table test2( var1 text )insert into test1 values ( '-- [ CustomerType = 1 ]' )insert into test2 values ( '-- [ CustomerType = 1 ]' )select * from test1, test2where test1.var1 like test2.var1The last query surprisingly did not return any results. However when itook of the '[' in the text data and had something like thisinsert into test1 values ( '-- CustomerType = 1 ]' )insert into test2 values ( '-- CustomerType = 1 ]' )the query returned expected results, showing one row.any helpful would be great.Regards,Arun Prakash.

We have two tables:
Table1
Servers|Databases|Users|Names
Server1|Database1|User1|Name1
Server2|Database2|User2|Name2
Server3|Database3|User3|Name3
Server4|Database4|User4|Name4
Server5|Database5|User5|Name5
Table2
Servers|Databases|Users|Names
NULL |Database1|NULL |Name1
NULL |NULL |User1|Name2
NULL |NULL |NULL |Name3
Server5|Database5|NULL |NULL
I need to check Table1 by Table2 only on NOT NULL cells and if all of them in the row match do not return that row as the result. In this case it will be:
Results:
Servers|Databases |Users |Names
Server2|Database2|User2|Name2
Server4|Database4|User4|Name4
I used query like this:
SELECT a.Server, a.Databases, a.Users, a.Names FROM Table1
EXCEPT
SELECT ISNULL(b.Server,c.Server), ISNULL(b.Databases,c.Databases), ISNULL(b.Users,c.Users), ISNULL(b.Names,c.Names) FROM Table2 AS a, Table1 AS c
But for many rows (like 100 000) it takes ages to get results, any better way to work on this?

I have two tables in the same SQL database. Both have a similar numericfield. One field has the same number as the other field but is prefixedwith various letters. I know how to use LIKE but won't know the partialstring I am looking for. I am trying to use LIKE '%' + Field A orsomething that will do this.Eg.Table 1 Field A is 'A12345"Table 2 Field B is '12345"I want to find every record in Table 1 Field A that contains the exactField B data.*** Sent via Developersdex http://www.developersdex.com ***

What I am working with unfortunately is a very poorly designed and non-normalized database. Please don't criticize the design. I didn't design it, but I have to write queries against it.I have 2 tables. 1 is called EnterVolume. The other is ExitVolume. Similar columns exist in each.
CREATE TABLE [EventPortion].[EventEnterVolume](
[SequenceNumber] [int] NULL,
[TrialID] [nvarchar](255) NULL,
[TimeOfEvent] [int] NULL,
[UniversalTime] [nvarchar](255) NULL,
[SBOINumber] [int] NULL,
[SEntityPosUpdateIndex] [int] NULL,
[VolumeIndex] [int] NULL,
[code]....
The rules of the database state that for every EnterVolume row (for a given TrialID, SBOINumber, and OwnerBOI) there must be a corresponding ExitVolume row in the ExitVolume table.What I need to do is to capture the paired TimeOfEvent entries from each table for each paired row. Nothing says that an SBOI cannot enter and exit a OwnerBOI's volume several times during the same Trial.Every time a SBOI Enters an OwnerBOI's volume during a certain trial, a row is created in the EnterVolume table. And Likewise when Exiting a OwnerBOI's volume during a certain trial, a row is created in the ExitVolume table.
So here is a query that I attempted, but gave undesirable results:
SELECT EV.TimeOfEvent AS [Enter Time], XV.TimeOfEvent AS ExitTime
FROM IntegratedTest1.EventPortion.EventEnterVolume AS EV INNER JOIN
IntegratedTest1.EventPortion.EventExitVolume AS XV ON EV.TrialID = XV.TrialID AND EV.SBOINumber = XV.SBOINumber AND EV.OwnerBOI = XV.OwnerBOI
Here is some sample data:
EnterVolume
TrialID SBOI OwnerBOI TimeOfEvent
1 A D 5
1 A D 2000
[code]....

I am using SQL 2005 merge replication with a publisher managing about 45 articles(tables) with about 10 subscribers (remote servers). The problem is that we had to re-start replication from scratch and noticed that, although the publisher's tables have the default values, the subscribers did not get the default values with the initial snap shot, schema building..?!?
I now have to go over 450 tables (10 remotes SQl servers at 45 tables each) and 'reset or set' over 1,000 default values. Meanwhile, the system is down...omg...so not good.
Is there a script out there that automatically extracts the default values from a table and set it to another exact table with the same structure? any ideas?
Thanks..CF
btw, i'm no scripting wizard....help!.

Hi All.
I'm having some issues with what seems to be a simple update statement but is giving me grief when one or both of the columns I'm comparing are null. My statement (simplified) is as follows:-
UPDATE
TAB_A
SET
TAB_A.TRADCODE = TAB_B.TRADCODE
FROM
TADS_STAGE.DBO.UNCLBRAMDEPT TAB_B
JOIN
TADS.DBO.UNCLBRAMDEPT TAB_A
ON
TAB_B.BRANCODE = TAB_A.BRANCODE
AND
TAB_B.MERDCODE = TAB_A.MERDCODE
AND
(
TAB_B.TRADCODE <> TAB_A.TRADCODE
)
If either of the TRADCODE fields (or both) are null then the comparison fails to return the row to update. I've tried setting the ANSI_NULLS setting to off, this has no effect, presumably because it will only work when comparing a column to a variable or evaluating if the column is null itself.
I've considered using ISNULL, but if one of the columns happens to contain the value that I specify as the replacement value then the comparison will result true and not include the row.
I'd be grateful for any pointers!
Thanks in advance

Hi everyone,
I have 2 seperate databases and I need to check for rows that are different from each other in a table.
I used access to link the tables in a database and am using queries to check the tables. However, I am having trouble formulating the SQL. What I want to do is not just check for the ID field to see if it exists, but to make sure the whole row exists. How can I form an SQL statement for this?
I tried something like:
Select * from table1 where Column1 NOT IN (Select Column1 from Table2) AND Column2 NOT IN (Select Column2 from Table2). However, I do not think this is correct. I want to make sure that the rows are compared, not individual values.
Any help would be appreciated.
Thanks,
Pankaj

I'm having a bit of a brain melt.
I've got two identical tables (except for the names) and I need to run a query that outputs the rows that aren't in the primary table.
To clarify table one has 38,450 records and table two has 30,703. I need to output the records that are in table one but not table two.
Everything I've tried keeps returning the records that are in it. They have a ID as primary key and a userid field which is what I want to be able to list.
Any ideas?
Thanks.

I need to compare two tables and update the records that have changed.
The following code works great for that:
SELECT MIN(TableName) as TableName, ID, COL1, COL2, COL3 ...
FROM
SELECT 'Table A' as TableName, A.ID, A.COL1, A.COL2, A.COL3, ...
FROM A
UNION ALL
SELECT 'Table B' as TableName, B.ID, B.COL1, B.COl2, B.COL3, ...
FROM B
) tmp
GROUP BY ID, COL1, COL2, COL3 ...
HAVING COUNT(*) = 1
ORDER BY ID
However, I also need to compare the two tables and see if there are any new records or deleted records. What would those queries look like? Can they all somehow be combined into one query?

I am working with the article that MAK wrote on SecurityLogs http://www.databasejournal.com/features/mssql/article.php/3515886
I have completed this, but I have made some changes to the database (for normalization to 3NF purposes). I now have problems with a query.
I am trying to "Insert a new record in a table if it does not already exist in the table". To try to clarify I perform the following query:
INSERT INTO Tmp_Event
SELECT DISTINCT EventID, EventType, EventTypeName from Tmp
Which gives me the Tmp_Event table consisting of EventID's etc. (no duplicates). What I then want to do, is compare the 'Tmp_event' table and an already existing 'Event' table. These two tables are in fact identical. I would like to insert any records from 'Tmp_Event' into 'Event' if they do not already exist in 'Event'.
This query gives me all records that do not exist in 'Event'
SELECT EventID, EventType, EventTYpeName from Tmp_Event
WHERE EventID NOT IN (SELECT EventID from Event)
How can I change this query into performing an INSERT INTO Event as well?
Hope this makes sense :)

I have two tables that share (supposedly) 2 fields (PartID and RaceID) and those two tables should be identical as far as those two fields are concerned. That is, there should be the same number of rows in both tables and if listed in the same sort order in reference to these two fields, they should be identical. The problem is, they are not. There are in excess of 3000 records in each field and I need to write a query that will allow me to compare them row-by-row.
I am using sql server 2000 and I am (kind of)familiar with the SQL Query Analyzer. What I really need to know is how to write the select statement that will allow me to compare the two tables line-by-line to find the discrepancies or, better yet, simply show the discrepancies so I can focus on them.
Thanks!
