Join Returns More Than One Row, Post Code Regular Expressions
Mar 23, 2006Hi,I trying to write a select statement that will return each of my salesmen a region code based on a table of post codes using wildcards... eg.MK1 1AA would be matched in the region code table to MK1%SELECT dn.DEALER_CODE, dn.NAME AS DNAME, rc.REGION_ID,rc.POST_CODE, dn.POSTAL_CODEFROM REGIONAL_CODES rc CROSS JOINDEALER_NAW dnWHERE (dn.POSTAL_CODE LIKE rc.POST_CODE)The above statement works BUT there are some post code areas such asour friends in Milton Keynes that are split into two regions... eg MK1is region id 2 and MK10 is region 3.So a dealer with post code MK10 1AA would be matched to both rowsreturning duplicatesPOST_CODE REGION_IDMK1% 2MK10% 3I think the answer would lie in a subquery which returns the ID of theregion with the longest length of the postcode match (e.g.len(POST_CODE) for the rc table... return only the MAX....any ideas????Any help muchos appreciated, and I apologies now for the naming of thedealers name as a reserve word... not me!Ct

Jan 2, 2008Hi all,
I have the following T-SQL code of Common Table Express (CTE) that works in the SQL Server Management Studio Express (SSMSE):
--CTE.sql--
USE ChemAveRpd
GO
WITH PivotedLabTests AS
(
SELECT LT.AnalyteName, LT.Unit,
Prim = MIN(CASE S.SampleType WHEN 'Primary' THEN LT.Result END),
Dupl = MIN(CASE S.SampleType WHEN 'Duplicate' THEN LT.Result END),
QA = MIN(CASE S.SampleType WHEN 'QA' THEN LT.Result END)
FROM LabTests LT
JOIN Samples S ON LT.SampleID = S.SampleID
GROUP BY LT.AnalyteName, LT.Unit
)
SELECT AnalyteName, Unit, avg1 = (abs(Prim + Dupl)) / 2,
avg2 = (abs(Prim + QA)) / 2,
avg3 = (abs(Dupl + QA)) / 2,
RPD1 = (abs(Prim - Dupl) / abs(Prim + Dupl)) * 2,
RPD2 = (abs(Prim - QA) / abs(Prim + QA)) * 2,
RPD3 = (abs(Dupl - QA) / abs(Dupl + QA)) * 2

===========================================
How can I execute this set of the CTE.sql code in the VB 2005 Express via the Stored Procedure programming?
Please help and respond.
Thanks in advance,

Help With Converting Code: VB Code In SQL Server 2000-&&>Visual Studio BI 2005
Jul 27, 2006Hi all--I'm trying to convert a function which I inherited from a SQL Server 2000 DTS package to something usable in an SSIS package in SQL Server 2005. Given the original code here:
Function Main()
on error resume next
dim cn, i, rs, sSQL
Set cn = CreateObject("ADODB.Connection")
cn.Open "Provider=sqloledb;Server=<server_name>;Database=<db_name>;User ID=<sysadmin_user>;Password=<password>"
set rs = CreateObject("ADODB.Recordset")
set rs = DTSGlobalVariables("SQLstring").value
for i = 1 to rs.RecordCount
sSQL = rs.Fields(0).value
cn.Execute sSQL, , 128 'adExecuteNoRecords option for faster execution
rs.MoveNext
Next
Main = DTSTaskExecResult_Success
End Function
This code was originally programmed in the SQL Server ActiveX Task type in a DTS package designed to take an open-ended number of SQL statements generated by another task as input, then execute each SQL statement sequentially. Upon this code's success, move on to the next step. (Of course, there was no additional documentation with this code. :-)
Based on other postings, I attempted to push this code into a Visual Studio BI 2005 Script Task with the following change:
public Sub Main()
...
Dts.TaskResult = Dts.Results.Success
End Class
I get the following error when I attempt to compile this:
Error 30209: Option Strict On requires all variable declarations to have an 'As' clause.
I am new to Visual Basic, so I'm on a learning curve here. From what I know of this script:
- The variables here violate the new Option Strict On requirement in VS 2005 to declare what type of object your variable is supposed to use.
- I need to explicitly declare each object, unless I turn off the Option Strict On (which didn't seem recommended, based on what I read).
Given this statement:
dim cn, i, rs, sSQL
I'm looking at "i" as type Integer; rs and sSQL are open-ended arrays, but can't quite figure out how to read the code here:
Set cn = CreateObject("ADODB.Connection")
cn.Open "Provider=sqloledb;Server=<server_name>;Database=<db_name>;User ID=<sysadmin_user>;Password=<password>"
set rs = CreateObject("ADODB.Recordset")
This code seems to create an instance of a COM component, then pass provider information and create the recordset being passed in by the previous task, but am not sure whether this syntax is correct for VS 2005 or what data type declaration to make here. Any ideas/help on how to rewrite this code would be greatly appreciated!
How To Show Description In Report Instead Of Code (Desc For Code Is In Master Table)
Mar 28, 2007Dear Friends,
I am having 2 Tables.
Table 1: AddressBook
Fields --> User Name, Address, CountryCode
Table 2: Country
Fields --> Country Code, Country Name
Step 1 : I have created a Cube with these two tables using SSAS.
Step 2 : I have created a report in SSRS showing Address list.
The Column in the report are User Name, Address, Country Name
But I have no idea, how to convert this Country Code to Country name.
I am generating the report using the Layout tab. ( Data | Layout | Preview ) Report1.rdl [Design]
Anyone help me to solve this issue. Because, in our project most of the transaction tables have Code and Code description in master table. I need to convert all code into corresponding description in all my reports.
Thanks in advance.

Expressions
Jun 7, 2006
When creating expressions we have access to a list of functions. It is my understanding that while these functions seem to have the same names and parameters as SQL functions, they are not so. They are implemented in the package libraries themselves. It is also my understanding that this function library cannot be extended to add new ones.
Am I correct? If so... why not?
Leaving alone the fact that they follow the same screwy names as SQL (instead of .NET on which SSIS is built on) and what seems to be a limited library (i.e. You have YEAR(), MONTH(), DAY() functions but no HOUR(), MINUTE(), or SEC() functions -- instead you have to use DATEPART())
I mean honestly... a common expression for most people is using date and times for folder and filenames... So instead of a simple .NET type expression of DateTime.ToString("yyyyMMdd") or Format(DateTime.Now, "yyyyMMdd_hhmmss") I end up with the very complex:
(DT_STR, 4, 1252) YEAR( GETDATE() ) + RIGHT("0" + (DT_STR, 2, 1252) MONTH( GETDATE() ), 2) + RIGHT("0" + (DT_STR, 2, 1252) DAY( GETDATE() ), 2) + "_" + RIGHT("0" + (DT_STR, 2, 1252) DATEPART("hour", GetDate()), 2) + RIGHT("0" + (DT_STR, 2, 1252) DATEPART("minute", GetDate()), 2) + RIGHT("0" + (DT_STR, 2, 1252) DATEPART("second", GetDate()), 2)
Personally I find myself using Script Tasks and Variables to "build" my expressions and just use Expressions to set the property to the variable. (Which I think may defeat the full purpose of expressions.)
Any thoughts?

Subquery Expressions Help
Oct 31, 2007Hello all,
I have come across a road block once again and it is probably something fairly easy to do. I have 3 queries that give counts with different criteria. They are:
SELECT building, COUNT(asmt_number) AS Cnt FROM dbo.mr_gb_asmt WHERE (school_year = 2008) AND (due_date <= CONVERT (DATETIME, '2007-10-26 00:00:00', 102)) AND (publish_scores = 'N') GROUP BY building ORDER BY building SELECT building, COUNT(asmt_number) AS Cnt FROM dbo.mr_gb_asmt WHERE (school_year = 2008) AND (due_date <= CONVERT (DATETIME, '2007-10-26 00:00:00', 102)) GROUP BY building ORDER BY building SELECT building, COUNT(asmt_number) AS Cnt FROM dbo.mr_gb_asmt WHERE (school_year = 2008) AND (due_date <= CONVERT (DATETIME, '2007-10-26 00:00:00', 102)) AND (publish_asmt = 'N') GROUP BY building ORDER BY building
My question is how can I combine these three queries into one so that I only get one record set?
Thanks for all the help!
MS SQL:- Regular Expressions
Jun 24, 2008Hi, the Microsoft SQL Server version is 2000
Basically I want use a basic regular expression but can't seem to get the syntax right.
i want to compare ID_short = ID_Long
ID_short is a truncated version of ID_Long, and I want to search on the beginning only (hence I can't use the 'LIKE' comparative on it's own).
What is the syntax to use Reg Expressions (or if anyone knows a non RegExp way of searching the beginning please let me know).
Thanks
Can I Set Expressions Programmatically?
Apr 16, 2007I'm building SSIS packages through code and I would like to set the properties of some custom tasks (not data flow tasks) to expressions. I've done some searches but turned up nothing. This is the only thing I'm hitting a brick wall on at the moment; Books Online has been excellent in detailing how to create packages via code up to this point.
For the sake of argument, let's say I want to set the SqlStatementSource property of an Execute SQL task to this value:
"INSERT INTO [SomeTable] VALUES (NEWID(), '" + @[User:omeStringVariable] + "')"
What would the code look like?
Color Expressions
Jun 5, 2007Hey everyone,
I know that you can make an expression that will make it one color if a certain condition is met and a different one if it is not but is there anyway to make it so that if a number is less than another it's one color, if it's greater it's a different color and if they're equal it's a third color? Thanks for the help.

Boolean Expressions
Nov 12, 2007I have a unusual problem, well it is unusual becaue i cannot understand it.
I am retrieving the following data, Revenue, Sales, Commission, and calculating Commission Rate in the report itself.
I got warnings that a textbox that was attempting to calculate the Commission Rate was trying to divide by zero.
When I analysed the data, I realised that indeed there were instances when Revenue was 0.00 and therefore when calculating the commission rate, commission/revenue it returned an error.
I then thought I'd do the following in the expression field
=iif((Fields!RevenueGbp.Value = 0.00), "Zero", (Fields!Commission.ValueGbp/Fields!RevenueGbp.Value))
However this does not work. However if i tried the following Boolean query
=iif((Fields!RevenueGbp.Value = 0.00), "Zero", Fields!CommissionGbp.Value)
it does work. In fact if I use any other identifier or use two field thats add, subtract or multiplied with each other it will work. The problem only arises is when I decide to divide two fields together.
Strangely if the condition is satisfied - [Fields!RevenueGbp.Value = 0.00] - it will still try to work out the division even though it should just return Zero!
Anyone help?

Using Expressions In FOR LOOP
Apr 11, 2007I need to create a While Loop with the FOR LOOP task.
According to my SSIS book, "to set up a While Loop in the For Loop, simply create an expression that tests a variable that can be modified by some workflow either inside or outside the For Loop"
What I want to do is, put an FTP task (whose job it is to receive a file) inside the For Loop.
I want the control flow to go like:
FOR LOOP --> FTP task --> file received? --> NO --> set variable 0 --> FOR LOOP --> check for variable --> is variable 1? --> NO --> FOR LOOP --> FTP task
and so on, until the variable is set to 1, indicating the successful transfer of the file
According to my book, this can be done simply with the use of expressions.
My question is, how do I write the expressions, both for the FTP task (which will set the variable to 0 or 1), and then the expression for the For Loop, which will evaluate the variable in its expression?
So, seems like I need to write 2 expressions, but not sure how.
Any help appreciated.
Thanks

Date Conversion And Expressions
Aug 31, 2006I have a table with about 20,000 records that have a date field, stored as a datetime in the database like '8/28/2006 8:42:14 AM'. The dates range from March 2004 to current. What I would like to do is retrieve the dates in that format (month year) and put them in a dropdown. I have this so far:SELECT DISTINCT DATEPART(month, dte_date) AS Expr1, DATEPART(yyyy, dte_date) AS Expr2 FROM myTable ORDER BY DATEPART(yyyy, dte_date), DATEPART(month, dte_date)And the query returns the information that I want, but I can only bind one field to the dropdown. I was thinking that if I return the results a single expression (concantenate?) then I could bind that to the dropdown. I'm not sure as how to go about this. Also, the month returned is numeric and I would rather have the name of the month returned (like "July" instead of "7"). Thanks in advance to anyone who helps me.
View 4 Replies View RelatedNumeric Expressions And Aliases
Mar 8, 2006I'm in the process of building a site and converting views/tables/queries from an Access database to SQL. I've done this quite a few times, and never had any significant issues I couldn't figure out on my own.
In Enterprise Manager, I've created a view and in the query, I need to create an alias that is similar to below:
SELECT ((monthmult) + ((b2avg*15)-(av2*10)) + (lp1+lp2) + ((b1avg*30)-(av1*20))) as PIndexValue
which is how the formula reads in the Access view.
However, when I got to run the query, SQL strips out all of the parentheses and calculates the value in left to right order:
(monthmult + b2avg*15-av2*10 + lp1+lp2 + b1avg*30-av1*20) as PIndexValue
Which gives me an incorrect value.
Does anyone know why this is happening, or am I just unaware of the right way of doing it?
Thank you,

Regular Expressions In SQL 2005 Using C#
Sep 24, 2006Hi all,
i wrote a little function that is basically supposed to give me a match of a regular expression in C#. i tested it out in VS05 and it seems to work fine. It hits the fan when i try it on SQL Query analyzer once deployed. Anyone have any idea why?
here is the C# class that I deploy to a db using VS05.
using System;
using System.Data;
using System.Data.SqlClient;
using System.Data.SqlTypes;
using Microsoft.SqlServer.Server;
using System.Text.RegularExpressions;
public partial class RegExTest
{
[Microsoft.SqlServer.Server.SqlFunction(IsDeterministic = true, IsPrecise = true)]
public static string RegExMatch(string pattern, string matchString)
{
Regex r1 = new Regex(pattern);
if (r1.Match(matchString.TrimEnd(null)).Success)
{
Regex testReg = new Regex(pattern);
Match regMatch = testReg.Match(matchString);
string runnumber = regMatch.ToString().TrimEnd('_');
runnumber = runnumber.TrimStart('_');
return runnumber;
}
else
{
return null;
}
}
};
Basically i have a teststring that looks like abc_xxx_nnndef. xxx and nn are both numbers, and im using the pattern _\d{3}_ to test it out in SQL (i need the numbers between '_' and '_'). But it never even proceeds past the if statement in SQL i think. here is the basic SQL that i use to test the above function:
use northwind
go
declare @teststring varchar(50),
@pattern varchar(10),
@out varchar(50)
set @teststring = 'dw_012_34.ext'
set @pattern = '_\d{3}_'
set @out = dbo.RegExMatch(@pattern, @teststring )
select @teststring

Anyone have any suggestions as to why it works in VS 05 when I use it in a C# program, but fails on the SQL version?
Expressions And Datareader Source
Mar 12, 2007Greetings my SSIS friends,
Apologies for asking a similar question again but I am still non the wiser with this problem!
Let me explain to you my situation and the method I've adopted to try and solve it.
I have some source data residing in a SQL Server 6.5 database. The source data consists of a single table. For this example I will assume that my table contains only 2 columns, an ID column called result_ID and a Result_Name.
The idea is to retrieve new data each time the package is run. We will know this because the result_IDs in the source table will be greater than the maximum result_ID in my destination table . The way the package should work is like this :
1) Retrieve maximum result_ID from destination table
2) retrieve data from source table where result_ID > maximum result_ID from destination table.
My package consists of a
1) SQL Query Task which retrieves the maximum result_ID and places it in a user variable (type Int32).
2) A Data flow task with a Datareader source adapter which uses an expression to retrieve the data. My expression looks like this : "select * from result where result_id > " + (dt_str, 10, 1252) @[User::max_result_id]
When I run my package the first time all the rows are retrieved (as my destination table is empty to begin with). BUT when I run it the second time the same thing happens again!! All rows are retrieved.
I placed a breakpoint at the point where the variable gets populated with the maximum result_ID and true enough, the variable gets populated with the correct result_ID BUT then that variable gets reset to 0 in my expression!
This problem is driving me crazy! Has anybody out there experienced this kind of problem before?! What are the ways to solve it?!
Thanks for your help in advance.
Common Table Expressions
Aug 31, 2006Hi guys,
I know its not a good idea to give you a big query...but/...
