how can we copmpare string like
name=name
Hi,
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?
Best Regards,

Dear All:I encounter one problem when I want to implement my thought. My thoughtis that user want to search a record of someone but maybe user wouldtype wrong name or spell name wrong. I wish to compare the string whichuser inputed to the database column using "Socre Method". "ScoreMethod" has a variable "grade" to accumulate the score. I want toconvert the string to char array, and compare the char one by one. Ifthe string is more accurate , the grade is more high. At last, I choosethe most higher score record to show. How to do this thought with tsql?Could give me some tips or guide to learn? I will appreciate yourkindness, thanks.

EventDate datetime2(5) = ‘2015-10-22 10:19:59.12345’
ConsumerID bigint = 1234
SiteID tinyint = 15
EventDate will be converted to a bigint and then to a hex value
= 2015-10-22 10:19:59.12345 = 2015102210195912345 = 1BF714C8A0D4F699
ConsumerID will be converted to a hex value
= 1234 = 4D2
SiteID will be converted to a hex value
= 15 = F
The hex values will then be concatenated together and stored as a string (varchar). The application will handle the creation of the complex key
= ‘1BF714C8A0D4F699-4D2-F’
I am trying to argue against this approach and get them to store the values in their native form, in separate columns as a natural key.
To make matters worse, we need to use partitioning, where the partition boundary will be on a hexed datetime2(5) at weekly intervals. I was really hoping a proof of concept would show that hex string comparison could potentially put a row under a wrong partition, but so far, on an 8 million rowset, it is working fine.
For example, in the proof of concept, right partition boundary:
= '1BF398D53DFA1800'
(2014-12-15 00:00:00.00000)
contains rows
= '1BF3983242B9C000-1-2'
(2014-12-08 00:00:00.00000-1-2)
Through to
= '1BF398C373960580-2FAF3003-2'
(2014-12-14 23：59：00.00000-800010243-2）
The prior partition boundary is 1
= 'BF3983242B9C000'
(2014-12-08 00:00:00.00000)
How is this working, given that the string lengths (varchar) are different and the row value contains dashes and the partition boundaries are smaller in length without dashes? How varchar string comparison is working here?
I'm working on a program that reads in zip codes and then does some checking on them. Occasionally, the end user typos or transposes digits. It's easy enough to identify bad zip codes, but I would like to offer up a single recommendation. The problem is that there are often multiples to choose from. Is there a function or has anyone tried to figure out the delta between two strings?
Thanks
I'm trying to come up with a formula that will calculate the number of lines where two conditions are true.First, SLA must be either breached or achieved.And the second condition must be that the "country" and SLO group must be the same (these two values are located in different tables. So far I have only accomplished the first....
=CALCULATE(DISTINCTCOUNT([ID]),Data![SLA Result]="Breached")
I have tried adding FIND, EXACT or USERELATIONSHIP to the formula to no avail.... I keep running into the same error."The value for 'SLO Group' cannot be determined. Either 'SLO Group' doesn't exist, or there is no current row for a column named 'SLO Group'."
Country
SLO Group
SLA Achieved
SLA Breached

What i need is to create a function that compares 2 strings variables and if those 2 variables doesn't have at least 3 different characters then return failure , else return success.

Hi all,I have created this simple Stored procedure. But it gives me wrong result when I pass a parameter to it. But if I hard
code it, it gives me the right result.
The I check if the field value of 'Email' is exactly equal to the parameter '@Email'.
The field 'Email' is varchar, and CID is integer.
CREATE PROCEDURE EmailExists @Email varcharASSELECT CIDFROM CustomersWHERE Customers.Email = @Emailreturn
Instead, if I check the value directly, it gives me correct answer. The the following code works fine when I typethe Email directly in the code.
CREATE PROCEDURE EmailExists @Email varcharASSELECT CIDFROM CustomersWHERE Customers.Email = 'tomyseba@yahoo.com'
return
Can anyone tell me the reason for it.
Thanking you in advance

DECLARE @Teams AS TABLE(Team VARCHAR(3))

co-relation between comparison operators in WHERE Clause and the respective output.
how SQL 2012 would treat a literal string for a comparison similar to below. I want to ensure that the server isn't implicitly converting the value as it runs the SQL, so I'd rather change the data type in one of my tables, as unicode isn't required.
Declare @T Table (S varchar(2))
Declare @S nvarchar(255)
Insert into @T
Values ('AR'), ('AT'), ('AW')
Set @S = 'Auto Repairs'
Select *
from @T T
where case @S when 'Auto Repairs' then 'AR'
when 'Auto Target' then 'AT'
when 'Auto Wash' then 'AW' end = T.STo summarise
in the above would AR, AT and AW in the case statement be treated as a nvarchar, as that's the field the case is wrapped around, or would it be treated as a varchar, as that's what I'm comparing it to.
Dear All
I am new to the topic T-SQL.
I am trying to use T-SQL to merge the content of two tables (table1 and table2) into one table making sure there are no duplication.
I wonder if any body can let me have a simple code.

Hi...
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.
Is there a way to compare two similar tables? I'm more interested in finding out if the data content is exactly the same or not between the two tables.
Thanks for your help.
We are converting our project into new version. They have done lot of changes in new version including normalization/denormalization. I need to compare the old and new database.
Do you have any standard script or procedure like SQL Compare software?.
Let me know what are the possibilties we need to check.
Your help appreciated.

Good 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.
Hi 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 !

Hello 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?

I 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
I 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,

In management studio, is there a way to compare databases side by side?

Hi,
I have a table in sql server 2000.I delete some rows in the table.I would like to know the differences before & after deletion. Is it possible?
I 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?
I 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

View 1 Replies View RelatedAs many of you know I've been hunting down a SQL CE alternative / embedded DB that is easily portable among handhelds.
It turns out, that without paying for some other DB, there really aren't any good ones... Unless you go GPL, and the interpretation of GPL that most are using is that your code too is GPL even though you may only Dynamically Link to their app. I think this is likely wrong, but none the less I'm back here yet again.
What I'm looking for this time is a definition of how SQL Server CE is implemented, how it differs from a full blown DB, etc, so I can more thourally explain "why SQL CE" is an embedded DB, and how it isn't the full blown SQL Server that has a bad reputation with some.
My guess is:
SQL Server CE is implemented via DLL. There aren't sockets etc to allow you to connect, and it operates more like an advanced hash on the file system.
Please correct me if i'm wrong, or... send me a link where I can further research. Also, if you have another embedded DB as a suggestion, that's free of course, please point it my way.
Thanks!
How would one go about writing an expression such as:
var not in (a to g, s to z) in the expression builder to be evaluted with and iif statment
iif(var not in (a to g, s to z),var,"not in listed")
I would rather not have to write this in the SQL statement as a case statement.
Hi guys,
I'm trying to do a comparison of 2 data sets. Basically what I want is: 'where event date from event number -24 is earlier than the event date for event number -13'
To get the eventdate for the eventno's, I have the following 2 queries:
select eventdate
from caseevent, cases
where eventno = -24
select eventdate
from caseevent, cases
where eventno = -13
So what i'm trying to say is: I want it so that the value of the first query is compared to be LESS than the value of the second query...
Any help please????
Thank you!
