&&<= And Comparing Strings

Aug 20, 2007

Hi,

I have a strange problem I can't solve. I have a log table where a have for example a timecreated column where I store dates in the format 0704212112538707

What I want to to is to search for log posts that are in between two dates.

I have this SQL query: select * from log where timecreated >= '070421' and timecreated <= '070422'. With this question I only get hits from the date 070421. I would like to get both 070421 and 070422. I get no difference if I use < or <=.

How would I solve this

Comparing Range Within Strings.

May 1, 2007

Hello, my first post :)

I'm currently working on a project that involves IP checking, here's my scenario:

A user enters an IP address of 10.174.55.65 let's say, I want to somehow be able to check and see if this IP address is in between column A (It's called ip) which consists the IP data of 10.174.0.0 and column B (It's called EndingIp) which has the IP data 10.174.255.255, so generally speaking I'm checking for the 3rd and 4th spots within the IP address and I'm trying to see if it's between the IP's in column A and B.

The thing is these are all strings, so how do I approch a stiuation like that within SQL?

Btw, I attached a picture of the table to be more clear.

Thanks in advance for the advice...

Comparing Strings (Advanced Soundex)

May 11, 2006

Hello,

I need to compare movie names from two systems. In both systems these names are entered manually by operators. I would like to compare them and give a rating on how close these names are equal.

Stripping special characters, and spaces is just not enough. It can happen that they key in sligthly different names. I've tried to use soundex but as we have over 15000 movie titles over the years i'm getting to many equal soundexes to use this as a comparison key.

Any ideas if there are techniques to do this ...

Kind Regards

Comparing Two Strings Inside A Stored Procedure

Aug 14, 2006

Basically I have two strings.  Both strings will contain similar data because the 2nd string is the first string after an update of the first string takes place.  Both strings are returned in my Stored Procedure
For example:String1 = "Here is some data.  lets type some more data"String2 = "Here's some data. Lets type some data here"I would want to change string2 (inside my Stored Procedure) to show the changed/added text highlighted and the deleted text with a strike though.
So I would want string2 to look like thisstring2 = "Here<font color = "#00FF00">'s</font> <strike>is</strike> some data. <font color = "#00FF00">L</font>ets type some <strike>more</strike> data <font color = "#00FF00">here</font>"
Is there an way to accomplish this inside a stored procedure?

Concatenate Strings After Assigning Text In Place Of Bit Strings

Feb 19, 2007

I have a whole bunch of bit fields in an SQL data base, which makes it a little messy to report on.

I thought a nice idea would be to assigne a text string/null value to each bit field and concatenate all of them into a result.

This is the basic logic goes soemthing like this:


select case new_accountant = 1 then 'acct/' end +

case new_advisor = 1 then 'adv/' end +

case new_attorney = 1 then 'atty/' end as String

from new_database

The output would be

Null, acct/, adv/, atty, acct/adv/, acct/atty/... acct/adv/atty/

So far, nothing I have tried has worked.

Any ideas?

Comparing Dates In SQL

Jan 28, 2006

I am wondering how I would create a SELECT that will select the most recent date from one of two tables. For example, table1 has a field called LastUpdate and table 2 has a field called LastUpdate.  I need to grab only the most recent date.   I tried this using an inner join...but that didn't work because it only picks the lastupdate form one table only.  talbe1 and table2 are tied by table2.table1id. 
Can anyone help?

Comparing Dates.

May 23, 2006

Hi All,
I have a database field (datestamp) which returns the date the records were inserted into the database. The datestamp was created with the now(); function in .net and is in the following format: 5/23/2006 2:27:45 AM
I basically want to return all records that were inputted more than 28 days ago. I have had alook though some other posts and below is the closest query that i could find but unfortunately it does not work for me.
SELECT id, datestampFROM table WHERE datestamp > DateAdd(d, 28, GetDate())
Thanks in advance,

Comparing Dates

Jul 10, 2001

How do i compare 2 dates without comparing their Time portions. I have a Datetime column in my table which for example has values :-

6/6/2001 7:23:42 PM
6/6/2001 8:01:08 PM and so on....

I have a Stored Procedure in which i am trying to fetch values from this table. The SP has 2 DateTime parameters @DateFrom and @Dateto. This SP is called from a Web page. On the Web Page the user just enters mm/dd/yyyy values for the 2 Date parameters. Therefore the Time portions defaults to 12:00 AM. So when the user passes 6/6/2001 as Date From and 6/6/2001 as Date To values, he doesn't get back the 2 records mentioned above since the Time portion makes the 2 records fall out of the date range.

Is there a way to just do a comparison on the Date portions i.e. give me all the records for 6/6/2001 irrespective of the time. I don't wan't to do individual comparisons for Day then Month and then Year.

Thanks
Sanjay.

Comparing And Filtering??

Sep 1, 2003

Hello all,

I'm new to SQL Server so if the following sounds stupid then apologies. I am trying to design a query which compares columns and filters according to the result of the comparison. We are a UK based charity that provides financial help to families with disabled children (www.familyfund.org.uk). We have a large database (250,000 entries) which we know contains some duplicate/split files from a recent migration. We need to identify these files but not delete them. Currently I am using the following:

SELECT dbo.Families.famId, dbo.Address.street, dbo.Children.childId, dbo.Address.postcode
FROM dbo.Children INNER JOIN
dbo.Families ON dbo.Children.family_no = dbo.Families.famId INNER JOIN
dbo.Persons ON dbo.Families.famId = dbo.Persons.famId INNER JOIN
dbo.Address ON dbo.Persons.addressId = dbo.Address.addressId
WHERE (NOT (dbo.Children.eligStatus IN (3, 4)))
GROUP BY dbo.Children.childId, dbo.Address.postcode, dbo.Families.famId, dbo.Address.street
HAVING (dbo.Address.street IS NOT NULL)
ORDER BY dbo.Address.street

Obviously this returns all 250,000 records and then we have to search manually. We would like to run a query which compares families.famID to address.street so that where famId has more than one address attched it is returned to the results grid. Does this make sense? is it possible? Any help would be gratefully received

Thanks in advance
Mark

Comparing Two Databases

Comparing Databases

Sep 28, 2005

Hey all,

Trying to compare unique fields from two databases.

Basically what i'm trying to do is get all of the id's out of one field that don't exsist in the 2nd database.

so I have this query


Code:


select Distinct Id
from table1
where ID!= (select Distinct ID from table2)



I'm getting this error

Server: Msg 512, Level 16, State 1, Line 1
Subquery returned more than 1 value. This is not permitted when the subquery follows =, !=, <, <= , >, >= or when the subquery is used as an expression.


Now I don't understand why because then I query
select id from tables 2

I only get 1 value for each row.

Now you should know, the two columns in either table are different, in one of them the first value is "1" in the other the first value is "00000001" although I don't think that should effect anything.

Any idea's?

Thanks

Comparing Two Dates - Need Help!

Aug 25, 2005

Hi, i got this query below, which I'd like to use to compare two sets of date...


select count(*) as rec, convert(char(6),dateEntered,13) as dateEntered from EmailTracker where chtype = '1' AND convert(char(12),dateEntered,13) >= '"& stdate &"' AND convert(char(12),dateEntered,13) <= '"& endate &"' group by convert(char(6),dateEntered,13)


the format of the stdate and dateEntered (a datetime datatype) looks like - 25 Aug 2005

right now, the query simply uses the first 2 letters of the date to fetch the record. That would not do the job as i want the thing to compare the whole lot! not just the 1st two letters...

Any help pls?

Sql For Comparing Two Tables

Aug 2, 2004

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

Comparing 12-Hr Dates

Apr 4, 2008

I will try to explain my problem as best as possible without going into too much detail.

Basically I have two tables,
AgentSchedule
AgentPunchData

These tables both contain agent names.

The schedule table has a column called "SHEND" which is a DATETIME datatype which identifies when an agent shift should end.

The entries all have a date attached which means nothing, for example "12/30/1899 9:00:00 PM"

The PunchData table has a column called "LOGOUT" which is also a DATETIME, the entries will have the real date and look something like this: "3/28/2008 9:23:00 PM"

I need to strip the date out of these functions so I can compare the times. I need to query the databases and return any instances where the LOGOUT time is > the shift end time (SHEND).

So far nothing I've tried has been successful. I'm completely stumped, I've tried so many different things and nothing compares the two times correctly. SQL DATETIME is the biggest pain in the ass, I wish we had SQL 2008 so I could just use TIME.

Comparing Dates

Jun 3, 2008

Hello,

I have some code that is trying to first find the first date of service that a person visited. Using the min function is not working. Is there another function? Right now I am still getting multiple rows for each person instead of just the first visit.

Then I want to be able to compare the first date of service to the date of birth and determine if the patient first visited before they were 2 years old. I can't figure out how to do this.

select distinct b.person_id,b.date_of_birth,min(a.enc_timestamp)
from patient_encounter a
join person b on a.person_id = b.person_id
where b.date_of_birth >= '20060301' and b.date_of_birth <= '20060531'
group by b.person_id,b.date_of_birth,a.enc_timestamp
