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'.
DECLARE @Teams AS TABLE(Team VARCHAR(3)) INSERT INTO @Teams SELECT 'IND' UNION SELECT 'SA' UNION SELECT 'AUS' select Team from @Teams where Team > 'AUS'
[code]....
co-relation between comparison operators in WHERE Clause and the respective output.
We can use comparison operators with strings as well. Hence, I tried to use the following query on a SQL Server 2012 instance with the sample AdventureWorks2012 database (the collation of the database and of the column is the default:
SQL_Latin1_General_CP1_CI_AS):
USE AdventureWorks2012 ; GO
--Returns 5 records SELECT pp.Name FROM Production.Product AS pp WHERE pp.Name >= N'Short' AND pp.Name <= N'Sport' ; GO
The query only returns 5 records. This despite the fact that the search is an inclusive search and the Production.Product table contains records that begin with "Sport".
Now, when I replace "Sport" with "Sporu" (just moving one character up in the alphabet to verify whether characters after the word have any impact on the search) gives me 8 records.
USE AdventureWorks2012 ; GO
--Returns 8 records SELECT pp.Name FROM Production.Product AS pp WHERE pp.Name >= N'Short' AND pp.Name <= N'Sporu' ; GO
What's going on inside of SQL Server that allows it to fetch "Short-Sleeve Classic Jersey" for the starting word "Short" but prevents it from fetching "Sport-100 Helmet" for the ending word "Sport" despite the search being an inclusive search?
I want know where can I find information about valid expresion types for each one of de Arithmetic Operators, Bitwise Operators, Comparison Operators, Logical Operators, Unary Operators in SQL server. I want something like this.
for (+) ADD, syntaxis -> expression + expression
expression Valid? result type ----------------------------------------------------------------- int + int ok int int + bigint ok bigint char + char ok char <- (+) works like concatenation char + int ok char??? image + bit error - binary + int ok binary???
for (*) MULTIPLY, syntaxis -> expression * expression
expression Valid? result type ----------------------------------------------------------------- int * int ok int int * bigint ok bigint char * char error - char * int error - image + bit error - binary + int ok binary????
for (<) LESS THAN, syntaxis -> expresion < expression
expression Valid? result type ----------------------------------------------------------------- int < int ok bit??? char < char ok bit??? char < int ok bit??? image < bit error -
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
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 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.
Hi I just got a paging procedure from the internet and it’s working just fine, but I would like to return the numbers of pages too. So I used the Count() function to retrieve all records on the table and divided by the page size, but even I doing with float number, this is returning a integer number. I just started with SQL Server, does some knows what is wrong with the following code? or knows a better way to do it.
Declare @Records int, @Pages float, @hey int
Set @Records = (Select Count(*) as 'Friends' From friends
What am I missing? I can only select 1 operator to inform. Should an 'operator' be redefined to have multiple addresses, if so, how should they be delimited?
I have an implementation of the UDT - 3-dimentional vector. In my code I have implemented add, subtract and multiply methods for the type. I have also implemented overloaded operators for +/-/* in my C# code. Those overloaded operator are working as expected in C# tests. However when I€™m trying to use +/-/* operators in T-SQL over my UDT it returns the following error:
Invalid operator for data type. Operator equals add, type equals Vector.
The following fragment does work:
DECLARE @v1 Vector, @v2 Vector, @v3 Vector;
SELECT @v1 = CAST('1,1,1' as Vector), @v2 = CAST('2,2,2' as Vector)
SELECT @v1 = CAST('1,1,1' as Vector), @v2 = CAST('2,2,2' as Vector)
SELECT @v1 'v1', @v2 'v2', @v1+@v2 'v1 + v2'
I guess that SQL Server is not aware of the operators€™ overload I have implemented in the C# code. Is there any way to instruct SQL Server to use overloaded operators in the T-SQL so the code will look naturally @a + @b instead of @a.[Add](@b) and as a result use standard summary functions SUM() instead of writing user defined aggregate function for the Vector type field?
I'm not sure which section this really comes under and I think 'availability/disaster recovery' is probably the most applicable, sorry if it isn't.
I have SQL Server 2005 set-up and about 50 jobs listed, now, these jobs were configured before an operators with alerting by email was set-up... so, none of the jobs when fail alert an operator.
Is there any way I can automate a solution so if any job fails a designated/or default operator will be emailed and told what happened? Or would I need to edit each job manually to set this?

I am trying to create a stored procedure that filters some customers. The field in wich I am trying to apply the filter is the age field. The problem is that I need to be able to select the comparison operator =,<,>,=<,>=,<>. I was trying to do it with the following code:
Select CustomerName From Customer Where (CustomerAge & @Operator & @Age)
But sql Server shows an error telling me that @Operartor couldnt be converted to int.
I dont know if I am in the right track or way off, how is this done?
Hello, how do you setup a Profiler filter, that has mixed AND/OR operators. Thru the Profiler GUI, I don't even see how you would ask for any statement/proc with READS over 10,000 OR DURATION over 1000ms. How do you do an "OR" thru the GUI?
Forgetting the GUI and doing traces thru scripts, the @logical_operator isn't too logical, and I can't find any description for setting this parameter. If you only have one filter, it doesn't matter if you set it to 0 (AND) or to 1 (OR)... But if you want multiple filters, so one filter is Reads >= 10,000 and the other filter is Duration >= 1000ms., how do you do that? I tried it with the @logical_operator of "1" on both, but then I also got other events with a NULL value in READS.
Hi all, real basic question: I can't seem to find a basic reference that tells me the syntax and allowable values of parameters in common functions such as Format or CDate when editing a Field Expression in Visual Studio (Report Definition Language?). Where would I start?
For example, I've discovered that the Format function "Returns a string formatted according to instructions contained in a format String expression.", and the string expression can have values like "D" and "d" which produce different results, but where would I find out what the allowable string expressions are and their meaning?
I have also been guessing at the syntax of the CDate command with no luck. I need a reference that tells me what the different function parameters mean.
Hello everyone, is there anyway to use an update sub query in a case expression , something like this for exampleselect username,(case when password ='606' then (update users set username = 'me' where id= '3') else password end) from users i have been googling this issue just with no usefull resultsthanks for any replyMahmoud Manasrah
UPDATE A SET ConsumerLogon = (SELECT email FROM TABLE B WHERE userNumber = LEFT (A.ConsumerLogon ,CHARINDEX ( '@' , A.ConsumerLogon , 1 ) -1) )
Seems like the subquery expression does not receive ConsumerLogon from the outer query.is this possible to refer to outer query in subquery expression?
I am getting an error from the case part of the select statement below which reads 'Incorrect Column Expression' then it quotes the case statement. All I am trying to do is convert and return the weight value to kilos if it was entered in pounds.
I am working with Excel, then within Excel I am using MS Query to query a database. I am trying to use the CAST function on a field with numbers (1,2 or 3 digits) so I can convert it to a text value with three digits, i.e. 1 would read 001, 12 would read 012, etc.
I am not using CAST in the design grid. Is this even possible?
I am modifying the underlying SQL code. Here is the line that is giving me trouble:

I have SQL Server 2000 Developer Edition on my laptop which I want to remain for work development purposes (my work uses SQL Server 2000). However, I'm developing a .NET application which requires a database back-end.
Can I install SQL Server 2005 Express Edition alongside SQL Server 2000? Or does 2005 overwrite 2000?
If no to the first question then how do I develop the system/database in SQL Server 2000 but delpoy it to the user using 2005 Express Edition?
I am in the midst of writing a query to return a range of product BIN LOCATIONS from a warehouse stock levels program.I know the start and end BIN LOCATIONS for the warehouse, e.g.: Start - #00000, and End - Z10000.However I cannot hard code these into the program, instead I want my operator to designate the first letter of both the start and end BINS locations, and then hit the 'go button'.Towards this end I have declared a couple of variables in my SQL, as follows -
Code: declare @strBin varchar(10) set @strBin = '' if @strBin = '' set @strBin = '#%'
declare @endBin varchar(10) if @endBin = '' set @endBin = 'z%'
My challenge is writing a relevant WHERE clause for my select statement, I have tried the following -
Code: where BINLOCAT.BINLABEL between @strBin and @endBin order by BINLOCAT.BINLABEL
Whilst the clause above does not cause any errors, neither does it return any results.My first thought is that the BETWEEN operator does not accept wildcards. But if this is correct then how do I go about allowing an operator to enter the start, and end BINS without typing the entire BIN string (e.g.: #00000)? I have tried >= @strBin and <= @endBin, but I am having a similar issue with no errors, and no data returned.

How to Protect From SQL Injection in ASP.NET and SQL 2005 for custom query expression?In my project, I allow user to custom query expression through UI, such asstring queryCondition=' sale>20 and sale <100'string queryCondition=' createDate>"10/10/2005"'string queryCondition='Fullname like "%Paul%" '...I construct SQL based the queryCondition string, such as string mysql='select * from mytable where '+queryConditionI know it's very dangerous because of SQL Injection, but it's very convenient for user to custom query expressionCould you tell me how to do? many thanks!
