Finding Max/Min Value In A Column When Row Data Repeat
Feb 13, 2008
I have a table. In that table I have a list by student number that lists the entry dates into a particular grade. When trying to list only the first time entered, there is no unique way to identify one row from another other than the date. Is there a way to use max or min to only pull one date per student number? I have done a series of case when statements and I am able to get it down to 1 to 2 entries per student number, but I need to get it down to only 1 date per student number.
Thank you for your help

I have my first SSIS package almost working, but I'm having an odd problem and can't find any information to help resolve it.
I'm importing from a flat file (csv) to an existing table (append). I've got a Derived Column transformation in the middle to do some data cleanup. It's all working except for one little problem...
One of the transformations is 'REPLACE([Column 3],"^","; ")', output to a new column. (The input file has a field that uses carets as delimiters between an unknown number of items; I'm changing that to semicolons for easier reading.) Not all rows have data in this column, some will have one item, some will have multiple items.
The REPLACE works except that it fills in repeated data for all the blank rows.
Example:
Incoming data is:
1 Smith,Jane^Jones,Jane
2 Brown,John
3
4 Adams,James^Adams,Jim
5
6 White,Debra
Data inserted into the table is:
1 Smith,Jane; Jones,Jane
2 Brown,John
3 Brown,John
4 Adams,James; Adams,Jim
5 Adams,James; Adams,Jim
6 White,Debra
I've tried to use a Conditional to skip the empty rows, but I can't get that working at all (get syntax errors no matter what I put in).
Any suggestions on how to fix this would be most appreciated!
 SELECT  MAX(TIME_VAL) AS Duration1 ,  MIN(TIME_VAL) AS Duration2 ,  -- VALUE OF LATITUDE CORRSPONDING TO MAX(TIME_VAL)  -- VALUE OF LATITUDE CORRSPONDING TO MIN(TIME_VAL)  (Select LONGITUDE from (select LONGITUDE , row_number()    [Code] ....
I am not getting Correct values for StartLongitude , EndLongitude. How can i achieve this to get the val of latitude corssponding to max/ min of time_val column.
I have a table that stores part numbers and manufactuers. Somehow this table has become corrupt showing different manufacturers with the same part numbers.
I know this will take a bit of manual digging to fix, but I want to find a way to pull all rows that have the same part number that have different manufacturers, or just pull up any "duplicate" part numbers and I can determine what is right or wrong as far as the manufactuers and make those changes.
I have tried this, but it does not seem to want to work.
Code:
Select * from my_table Where partnumber = (select partnumber from my_table) and compName <> (select compName from my_table)
I have tried other variations of the same, but nothing seems to want to show me just the items that have the same part numnbers and different manufacturers. I do not care if there are duplicates of the same part number/manufacturer entries, just if the part number is duplicated where the manufacturers are not the same.
These are the rows I want to edit and group by part number. I have almost a million rows of entries and this is not something I want to go through row by row. :-P
In a tabular report I have one or more columns that need to be repeated on every new physical page when printed.
Viewing the report in the ReportViewer control allows such columns to be fixed using the "FixedHeader" switch, allowing the user to conveniently scroll the reports content while always having the fixed columns in sight. This is perfect. However, when switching to the Print Layout view or when printing the report, I would like to have these fixed columns be printed on every new page that is generated at the beginning of the table printed.
E.g. I have a report that has a huge number of columns that need to be shown. When printed, the columns need at least 6 pages' width. I would be very convenient if I could repeat e.g. the first column (containing some identificational information) on every of these 6 pages. It wouldn't hurt if e.g. 7 pages would be generated because of the repeated column(s).
I am using ssrs 2012 using sql server 2012. I have grouped by project name in the header now it is repeating horizontally i need to repeat it by vertically using project name  grouped by column.
We run 2014 enterprise. I tried this with both table and matrix controls to no avail.
In the table scenario, I drag the table control over, instruct ssrs that a group name will go into column 1 and a sales figure in column2. Then I highlight the sales figure cell, add a column group on month number and generate my report off some june and july data.
ssrs understands that the months now expand horizontally but the rows alternate one with june filled in (blanks in july) and the next with july filled in for the same group name. I believe I got all my sort by conditions set but am not sure.Â
I tried all sorts of combos in the tablix and group properties before giving up.
Hello, I€™m creating a cube with Analysis services 2000 and SQLServer 2000 that has the following structure: The fact table has a primary key and some measures:
Fact_Table
PKFact (the primary key) Measure 1 Measure 2
And I have some dimensions, but I€™ll put here the one of interest, this dimension has a foreign key to the fact_table, this is because it is really a €œdetail€? of the fact table, the interesting thing here is that this dimension not only has a foreign key to the fact_table, but also is a parent-child dimension:
Dimension_Table
FKFact (the foreign key to the €œPKFact€? field of the fact table) PKId (The id of the field for the parent-child relationship) FKParentId (the foreign key to this same table, this is, the parent of the field) TheLevel (the data€¦)
So, if I create the cube without the Dimension_Table (of course, I have more dimensions), the cube shows the data correctly, but when I include this dimension, the data of the fact_table starts to be repeated once for each row in the dimension table (once for each row that has the relation PKFact €“ FKFact of course), Somebody knows how I can avoid this data being repeated? I€™ve tried a lot of things but none works.. Please help!!
Hi, I have one data driven task set up in my DTS package. for some reason the connection to data source is not available when my package is scheduled to run,which fails the package. is there a way, I can set the task to try to execute again after a couple of minutes or 5 mins, maybe a predefined number of times before it fails the package? Thanks & Regards Naseem
I've never attempted to use the "Repeat Report Item with Data Region on Every Page " feature before. I'm trying to use it on text boxes with the data region being a matrix. I have a report that is two pages, and the text boxes are only appearing on the first page. Also, the matrix is appearing with zero space between it and the header. Any ideas?
I am using reportitem to show the data in the header from a table cell.i see the values just on the first page, from second page onwards reportitems not showing the values at all.
I am getting the reportitems values from a tables header cell and also made the tables header cell's property checked repeat header in all pages.
Header is appearing but the values in reportitems are not populating from page 2 onwards.
i tried / used everything including inserting group header still i don't get it towork.
I have a task to where I need to move a column from one table toanother. I want to be sure I update any view, stored procedure,trigger, etc. that references the column. I simply want a query thatwill report the related objects and then I will update them manuallybut before I go and try and figure out how to do this by querying thesys tables is there an sp_sproc that will do this?
I'm using SQL 2005 Server Management Studio - I go to the Northwind database - new query window and paste this code, I just found on this forum, to find the Identity column:SELECT C.name AS Colname, UPPER(U.name) AS Coltype, C.status AS Cstatus, C.ColId, C.Id AS Cid, C.length, C.xprec, C.xscale FROM syscolumns C JOIN sys.tables O ON C.id = O.object_id JOIN systypes U ON C.xusertype = U.xusertype WHERE O.name = 'Fred' AND C.status = 128 ORDER BY C.colid SELECT C.name AS Colname, UPPER(U.name) AS Coltype, C.status AS Cstatus, C.ColId, C.Id AS Cid, C.length, C.xprec, C.xscale FROM syscolumns C JOIN sys.tables O ON C.id = O.object_id JOIN systypes U ON C.xusertype = U.xusertype WHERE O.name = 'Products' AND C.status = 128 ORDER BY C.colid However, I get an error message saying:Invalid object name 'sys.tables'. What might I be missing here?

Hi,I'm having trouble running the following query:select * from message where text_body like ' ----------%'ie, five spaces followed by at least ten hyphens. The query doesn'tcomplete, so eventually I cancel it. If I remove the hyphens from thequery ("... like ' %'") then it runs fine (though it doesn't findthe correct data).Am I confusing SQL Server by using a wildcard or regular expression?(I'm using SQL Server 2000 - 8.99.760).Thanks in advance for any helpRichard
I always seem to come back to dataset issues. Nonetheless, here is my problem:
I am retrieving data using a stored procedure that lists the number of bookings per hour and the revenue that generates also per hour. So, you enter a single date in the stored procedure, for example 2001-10-01 and it will bring back 24 rows corresponding to the 24 hours (obviously) and two columns, one displaying the number of bookings and one displaying how much revenue.
Pretty simple so far.
I have a report using SQL Reporting Services that allows users to enter two dates and therefore you get two tables with the relevant dates data. For example, table one has date 1's data and table 2 has as you'd expect date 2's data. Both tables use different datasets.
The reason why I am using different tables and different datasets is that the stored procedure I use only allows the use of one date at a time therefore, I use a second dataset to generate the second date's data.
The problem occurs when I want to calculate a difference between the two date's data, for example have another table that shows the differrence between table one and table two for bookings for each corresponding hour.
Anyone have any ideas as to how I could achieve this?
I am using Access 2007 and I have 10 columns of data.
I am trying to select all the data from all 10 columns where the first column's data returns only the Unique values and the other columns return all the data from the row that is returned from the first column.
But that returns all the data in the table and all values in the Sorter column with duplicates because each row has distinct data.
I am trying to return unique values from [SFR Rates All].Sorter (the first column) and all the data from the other 9 columns that are contain the row with the unique value in Sorter.
I know that I am missing something basic but well, I can't figure it out.
I am trying to find a way where I can search for a column that is associated in all tables of the database. I have created a query but is not executing correctly.
SELECT t.name AS table_name, SCHEMA_NAME(schema_id) AS schema_name, c.name AS column_name FROM sys.tables AS t8 INNER JOIN sys.columns c ON t.OBJECT_ID = c.OBJECT_ID WHERE c.name LIKE '%Status%' ORDER BY schema_name, table_name;
I have a split string function that will take a comma delimited string and give back a table with all the values.I have a table that has a column with a comma delimited comma delimited list of states.
I can use a where clause to find one state in the table (such as all records that have CA in the states string).But need to find out how to find all the rows that have all or any of the states from a comma delimited parameter.Here is the schema
CREATE FUNCTION [dbo].[split] (@list nvarchar(MAX)) RETURNS @tbl TABLE (svar nvarchar(10) NOT NULL) AS BEGIN DECLARE @pos int, @nextpos int, @valuelen int
Could any suggest to me a good way to programmatically identify which SPsupdate a database column. I would like to create a cross reference for ourdatabase.
Example data CA1000 CA10001 CA10002 CA10003 CA11597 CA11603 CA1001 CA998 CA999 As you can see, CA11603 is the largest number in this list. When I try the follow sql code, SELECT MAX([MyCode]) FROM [MyTable] WHERE (SUBSTRING([MyCode], 1, 2) = 'CA') The largest number comes back as CA997 When I try MAX([MyCode]) FROM [MyTable] WHERE [MyCode] LIKE 'CA%' The largest number comes back as CA997
SELECT TOP 1 (SchoolMasterCode) FROM SchoolMaster WHERE (SUBSTRING(SchoolMasterCode, 1, 2) = 'CA') ORDER BY Schoolmastercode The largest comes back as CA10001 When I try.... SELECT TOP 1 (SchoolMasterCode) FROM SchoolMaster WHERE (SUBSTRING(SchoolMasterCode, 1, 2) = 'CA') The largest comes back as CA1278 What am I doing wrong?
Does anyone have a TSQL utility (that they can share) that recursively searchs sysobjects for a matching input parameter string(for instance column name) for stored procedure object properties that returns the stored procedure name?
I've got a rowset (intermediate result in a large query) that's equivalent to this table:
create table T (
K bigint, V bigint, W tinyint, primary key(K,W) )
What I want is "for each K, find the V associated with the largest W". Or,
select K,V from T t1 where W = (select max(W) from T t2 where t2.K = t1.K)
What I'd like is a solution that does not involve a self-join on the table (which the sub-query effectively is). The rowset can be sorted by (K asc, W desc), in which case I'm looking for the first (K,V) pair for each unique value of K.
In the larger query, T could have 100's of thousands of rows, and as I mentioned, T is the result of another query on my base tables. I can express T as a CTE easily enough, but the resulting query plan (using the sub-select, as above) ends up performing the query that generated T repeatedly in order to implement the self join.
I can save T into a temp table - in fact, that's what I'm doing now - but I'd rather avoid using a temp table if possible. This query needs to be of the highest possible performance, so if there's a no-temp-table, no-self-join solution, I'm all ears!
I could imagine making a CLR UDF that does the filtering that I want, but I'm not convinced that it'd be a good choice - any insights on whether that's worth trying would be appreciated as well.
finding one set of data within another set of data for update,so if within column 1 it finds the results from another select on another table, it updates a different column with the result.
Example
SELECT Title from H..Import_Table returns 'PRN - Concord' 'PRN - San Jose' 'SLP - PRN - San Jose' 'San Jose - PT - PRN'
