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...
I have two tables, one called SUBURBS and one called REGIONS.
The REGION table is more updated, but is missing certain values that are in the SUBURB table that i need to create a query for to not only compare wether the value existas, but to then insert that value in. Here are the table structures for the SUBURB and the REGION tables respectivly
MEMRGN (This relates to the EAC_REGION field in REGIONS) OLDREGION SUBURB PCODE STATE TempID
EAC_REGION REMAX_REGION REMAX_SUB_REGION SUBURB PCODE STATE BSPNAME DeliveryOffice TempID
I'm trying to put an expression into a view query column. I've already created a column which contains the results of a calculation in the form of an expression. What I don't know how to do is use comparison operators to return a boolean value for display. I'll give some examples of what I'm trying to do, using literal values just to simplify things...
So say I want to display the result of an expression in a view query column, as a boolean value (or BIT), as True or False. I've tried putting the following expressions into the column and none work:
4 < 5: Access converts this to the string '4 < 5' and it's just displayed as a string.
CAST( '4 < 5' AS BIT ): When run, the query displays the error 'Syntax error converting the varchar value '4 < 5' to a column of data type BIT.
Although I'm using Access 2003, It's just a front end for a SQL Server 2000 database. The actual SQL statement containing the latter SQL function is:
SELECT dbo.Tapes.No, dbo.Tapes.Status, dbo.Tapes.LastWrittenDate, dbo.Tapes.Pool, dbo.Tapes.Location, dbo.TapeJobs.No AS Expr1, dbo.TapeJobs.JobNo, dbo.TapeJobs.TapeNo, dbo.Jobs.No AS Expr2, dbo.Jobs.Date, dbo.Jobs.Successful, dbo.Jobs.RetentionRule, dbo.RetentionRules.No AS Expr3, dbo.RetentionRules.Name, dbo.RetentionRules.Description, dbo.RetentionRules.RetentionPeriod, dbo.RetentionRules.RetentionCycles, dbo.Jobs.Date + dbo.RetentionRules.RetentionPeriod AS AgedJob, CAST('4 < 5' AS BIT) AS Expr4 FROM dbo.RetentionRules INNER JOIN dbo.Jobs ON dbo.RetentionRules.No = dbo.Jobs.RetentionRule RIGHT OUTER JOIN dbo.Tapes RIGHT OUTER JOIN dbo.TapeJobs ON dbo.Tapes.No = dbo.TapeJobs.TapeNo ON dbo.Jobs.No = dbo.TapeJobs.JobNo
I'm new to SQL. I think the CAST function is the way forward, but I just don't know how to force it to resolve the expression '4 < 5'.
I'm developing a 2 year comparison rolling 12 month Sales report but am having problems with the query I'm using. Because I need to include every month (whether no sales or not) I have a calendar table named metaDates and each table gets outer joined as a result. (Forgive the long query) Please see below.
SELECT Customer.country, Order_Line_Invoice.prodcatid, MetaDates.[Month], MetaDates.[Year], isNull(SUM(Order_Line_Invoice.Sales),0) AS Sales , SUM(Order_Line_Invoice.Cost) AS Cost, ( isNull(SUM(Order_Line_Invoice.Sales),0) - isNull(SUM(Order_Line_Invoice.Cost),0) )AS GM, 'Current 12 Months' AS yearNum FROM MetaDates LEFT OUTER JOIN Order_Line_Invoice ON (MetaDates.Date = Order_Line_Invoice.InvoiceDate AND (Order_Line_Invoice.prodcatid IN (@GroupByFieldFilter)) ) LEFT OUTER JOIN Customer ON (Order_Line_Invoice.CustId = Customer.CustId and Customer.country IN (@country) ) LEFT OUTER JOIN Product ON (Order_Line_Invoice.ProdId = Product.ProdId) WHERE (MetaDates.Date BETWEEN dateadd(m, datediff(m, 0, DATEADD(month,-11,@EndDate) ), 0) AND @EndDate)
GROUP BY MetaDates.[Year], MetaDates.[Month], Customer.country, Order_Line_Invoice.prodcatid
UNION SELECT Customer.country, Order_Line_Invoice.prodcatid, MetaDates.[Month], MetaDates.[Year], isNull(SUM(Order_Line_Invoice.Sales),0) AS Sales , SUM(Order_Line_Invoice.Cost) AS Cost, ( isNull(SUM(Order_Line_Invoice.Sales),0) - isNull(SUM(Order_Line_Invoice.Cost),0) ) AS GM, 'Previous 12 Months' AS yearNum FROM MetaDates LEFT OUTER JOIN Order_Line_Invoice ON (MetaDates.Date = Order_Line_Invoice.InvoiceDate AND (Order_Line_Invoice.prodcatid IN (@GroupByFieldFilter)) ) LEFT OUTER JOIN Customer ON (Order_Line_Invoice.CustId = Customer.CustId and Customer.country IN (@country) ) LEFT OUTER JOIN Product ON (Order_Line_Invoice.ProdId = Product.ProdId) WHERE (MetaDates.Date BETWEEN dateadd(m, datediff(m, 0, DATEADD(month,-23,@EndDate) ), 0) AND dateadd(m, datediff(m, 0, DATEADD(month,-11,@EndDate) ), -1))
GROUP BY MetaDates.[Year], MetaDates.[Month], Customer.country, Order_Line_Invoice.prodcatid ORDER BY MetaDates.[Year], MetaDates.[Month]
That said the second outer join (Customer.country IN (@country)) never gets executed. It's really a simple concept. "Give me last 2 year sales by month (every previous and last month even if no sales) but only for the country the user is in"
Can someone help me out with this sql statement. Any help would be much appreciated.

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.
Hey guys what would be the easiest way to create a report of value changes for particular records from one day to the next..... ? Any suggestions would be greatly appreciated....
Hi there! can anyone help me out??? I need to compare a date from the database and the system date which will be coded in a store procedure in SQL... HELP!!!!!
I have a table with a field with a bit datatype. When I execute the stored procedure line if @bitvalue = 1 begin ... and the value is passes as 0 the statements beneath the begin execute. What am I doing wrong?
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.
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. Thanks, Ravi
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?

Morning! Folks, i want some links where i could find healthy stuff regarding New Features and Compliance levels, performance comparisons, TPC tests etc about SQL 2000 and Yukon specially. I've to submit a document regarding Top database features that shall be used for a Medical-Billing Software in plan.
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'.
In management studio, is there a way to compare databases side by side? Or would anyone know of any freeware out there that would do such a task? :beer:
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

I'm in need of a sql query that I'm not sure is possible. Here is anexample of how it's laid out.employee ID Job class Last Change Date12345 x 2/1/200412345 y 1/15/200412345 z 1/1/2004We know that this person is in job class 'x' because it's the mostrecent change. Is there a way to write a query that will exclude thelines 'y' and 'z' because they are currently incorrect?I would appreciate any help I could get. Thanks
As 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.
Hi, I have table with four fields ID, Date1, Date2,Date3,Date4. Dates are in numeric farmat like 20070927. How can i get largest date (from date1 to date4) on each row. Please suggest query. Thanks
Not sure if possible but I need to produce a monthly TOP 10 Ticket Category report which I retrieve with:
SELECT TOP (10) Category, COUNT(Category) AS Count FROM table WHERE (DATEDIFF(mm, open_date, GETDATE()) = 1) GROUP BY Category ORDER BY Count DESC
Now I need to know how many tickets there were for those same categories in the previous month so I want my result set to look somewhere along the lines of: Catagory - Count Month - Count Previous Month
I have 2 CLR Functions, both do the same thing, and they seem to perform the same based on testing. I am working on building examples for the web, and considered putting both up but I think the use of the Regular Expression is more of a best practice. Any thoughts on this?
Code Snippet using System; using System.Data; using System.Data.SqlClient; using System.Data.SqlTypes; using Microsoft.SqlServer.Server; public partial class UserDefinedFunctions {
[Microsoft.SqlServer.Server.SqlFunction] public static SqlBoolean IsValidIP(string IPAddress) {
int i; string[] ipParts; if (IPaddress == string.Empty) {
return false; } else {
ipParts = IPaddress.Split('.'); for (i = ipParts.Length - 1; i >= 0; i--) {
try {
int i = int.Parse(ipParts[i]); if (i > 255) return false; } catch {
return false; } } return true; } } };
Regular Expression Function:
Code Snippet using System; using System.Data; using System.Data.SqlClient; using System.Data.SqlTypes; using Microsoft.SqlServer.Server; using System.Text.RegularExpressions; public partial class UserDefinedFunctions {
[Microsoft.SqlServer.Server.SqlFunction] public static SqlBoolean IsIP(string IPAddress) {
// IP Address must be 4 part with each part 3 digits and less than 255. Regex regex = new Regex(@"^((2[0-4]d|25[0-5]|[01]?dd?).){3}(2[0-4]d|25[0-5]|[01]?dd?)"); return (SqlBoolean)regex.Match(IPAddress).Success; } };
My only beef with the Regular Expression function is that Regular Expressions are often over the head of many people. I could provide both examples, and cross link them, but I am not sure about that. Any opinions?
Hi,i need a column in a SELECT statement which returns always "true" (As a boolean value, not as a string)so I first tried SELECT field1, field2, true AS field3but this is not working. If I use "0 AS field3" this returns fine the 0, but this is not a boolean but a int.I also tried to make something like     "0 = 0 AS field"but also errors. In that context I discoverd that I could not compare values in the select field - I can use +,-+,* ... for having something like "2 * field1 AS field3" but I'm not clever enough to figure out how I would have a field "field1 < 12 AS field3" (ok I would use CASE, but I need the boolean return value...)Any ideas?Thanks in advance, Klaushow could I write something
