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 -
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 got this error for a calculated field that calls a public function of a custom assembly based on the report parameter values. The return type is an array of double.
Does SSRS 2005 supports the type double for a field? Can the data source of a field in a dataset be an array? Is there a way to pass the array to a field by reference and display the values at runtime?
I would appreciate any help since I could not find anything helpful on the internet and Microsoft document!
I'm trying to sum a column in a report. in Most columns I can just wrap the row level expression with "Sum()" and it works. However, I have run into a few that give the following error. The Value expression for the text box ‘Textbox241’ specifies a scope that is not valid for a nested aggregate.  The scope must be the same name of the scope specified by the outer aggregate or the name of a group or data region that is contained in the scope specified by the outer aggregate.Here is my row level expression that works.
I am trying to create a column chart that calculates the percentage of computers in our IT environment that are Actively communicating to our SCCM Server.
I have two datasets:
1. Total_Count_Of_AD_PC DataSet.
2. PC_With_Active_SCCM_Clients dataset.
Basically i wan to calculate the percentage for each Region (i.e. AP for Asia Pacific, EMEA, Americas).
Below is the Total_Count_Of_AD_PC  Dataset screenshot.
Below is the PC_With_Active_SCCM_Clients dataset.
Below is the expression that i used that is causing the error.
The Y expression for the chart ‘Chart2’ has a scope parameter that is not valid for an aggregate function. The scope parameter must be set to a string constant that is equal to either the name of a containing group, the name of a containing data region, or the name of a dataset.
I've been writing this stuff for a while, and can't seem to come to the conclusion of how I should be retrieving data and assigning this data to variables.
Since i'm using SQL Server, I'm convinced that I should be using the datareaders GetSqlDouble (or whatever) function, but this would mean i need my local variables to be one of the SQL types. The problem with that is, that there will have to be lots of conversions done by me to be able to use a SQL type in my application.
For instance, I have a class where i'm retrieving dates. In order to retrieve them correctly (Null values included), I need to retrieve them with GetSqlDateTime(), then when it comes time to display the date in a table, i must first check for nulls, then convert to a string. This seems to be very cumbersome. Would I be better off just using GetDateTime(), and the .ToString method, and ignoring Sql Types all together?
so, basically, how are you guys using your sql server data? with the supplied sql types, and doing all of the post-processing work manually? I feel like i'm having trouble conveying my issue...hopefully someone knows what i mean....i'd just like some direction to save trouble in the long run, since i feel like there's got to be a better way...
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?
Code below: [Code SQL] USE TestWarehouse IF ('dbo.TestItems') IS NOT NULL DROP TABLE [dbo].[TestItems]; GO CREATE TABLE [dbo].[TestItems] ( TestItem int not null IDENTITY (1,1)
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.
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.

I have created 1 report with 2 datasets. This report is attached to the 1st dataset.For example,1st one is "Smallappliances", 2nd is "Largeappliances".
I created a tablix and, the 1st column extracts Total sales per Sales person between 2 dates from 1st dataset (Small appliances). I used running values expression and it works fine.
Now, I would like to add another column that extracts Total sales per sales person between 2 dates from 2nd dataset (Large appliances). I am aware that I need to use Lookup expression and it is giving me the single sales value rather than the total sales values. So, I wanted to use RunningValue expression within lookup table to get total sales for large appliances.
This is the lookup expression that I added for the 2nd column.
I get this error when I preview the report.An error occurred during local report processing.The definition of the report is invalid.An unexpected error occurred in report processing.
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 have a problem at the moment, where the client wants to be able to type in a custom algebraic formula with add/minus operators, and then to have this interpreted, so that the related datasets are then added and returned as a single dataset.
An example would be having a formula stored of [a] + [b] - [c]
and if I were to write the SQL to apply that formula, I might write something like (let's assume 1:1 relationships with the ID's)
select a.a + b.b - c.c as [result] from z inner join tblA a on z.id = a.id inner join tblB b on z.id = b.id inner join tblC c on z.id = c.id
The formula can change though, maybe things like:
[a] + [b] + [c] + [d] [a] + [b]
The developer before me wrote something SQL-based where they parsed the string and assigned each value of the formula as either positive or negative (e.g A is positive, B is positive, C is negative, now sum the datasets to get the result), and then created one large table of values then summed them. This does (kind of) work, I'm just contemplating potential alternatives, as it is quite a slow process, and feels like it is quite convoluted, when I get into the details. If I were to do something like this in SQL, I'd normally want each part of the expression to be a column, and then to just apply the operators, but because the formula can change, then the SQL would need to be somehow dynamic for this approach.

I´m exporting an ms-excel file, then I use a lookup transformation to get a field from a SQL Server 2005 table. The Lookup transformation editor, after selecting the table, shows a warning that says:
at least one mapping between a column from available input columns ans a column from available lookup columns must be defined on the columns page.
So I try to make a relationship in the Lookup transformation editor's column tab where I find the Available input columns and the available lookup columns but I get the following error:
The following columns cannot be mapped: [Department, DEP_CLEGALCODE] One or more columns do not have supported data types, or their data types do not match.
The field in SLQ Server is varchar(10) and the input field is a derived column transformation; I have tried different Data Types but I always have the same error.
The DataFlow is: ExcelSource --> Derived Column --> Lookup --> Flat file destination
hello,everybody ,i use the AnalysisServicesExecuteDDLTask ,but it dap an error "DDL is not valid",i don't konw what is the problem and how to solve?thank you!
im doing a sum on a table and it either returns a number in decimal format or 'null' . The problem is when it returns null i want it to just make the text say '0.00'. So i did a test on the object that if it returns NULL just print '0.00' but if it is not null it tells me that there is a number there and i want to store that as a decimal and print it out. But i get an error for a type cast when im not it should not even be going to that part of the code. In the code below the first executescaler will return null so it should just go straight to the else. But it gives me the type cast error in the if that shouldnt be seen. The error and code are below. //Borrower NSF FEES cmd.CommandText = "select sum(itemamount) from postmtdtls where loanid='" + LoanID + "' and Transactioncode = '310'"; object temp = cmd.ExecuteScalar(); if (temp != null) { decimal B_NSFFees = ((decimal)cmd.ExecuteScalar()); borrowerPayoff_NSFFees.Text = String.Format("{0:#,#.##}", B_NSFFees).ToString(); //Borrower NSF FEES } else { borrowerPayoff_NSFFees.Text = "0.00"; //borrowerPayoff_NSFFees.Text = "0.00"; } Server Error in '/WebSite5' Application.

I'm trying to install MSDE SP3 which I downloaded from MS at http://www.asp.net/msde/. Following the instructions as best I can I unzipped the file into a Folder now called MSDE located on C: I then went to a command prompt and typed in the command given to start the install:
setup SAPWD=testsite SecurityMode=SQL
Hit enter and the installer started up and ran for a few secs and then came back with
The Instance named specified is invalid
There was no mention of including an instance name or the format for it.
Suggestions please?
Also, if I want to completly uninstall MSDE if I need to how would I do it?
