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
SELECT DISTINCT mx.stu_num,
CASE WHEN er.STU_NUM = ep.STU_NUM
THEN er.enterdater
ELSE CASE WHEN ea.STU_NUM = ep.STU_NUM
THEN ea.enterdatea
ELSE CASE WHEN eb.STU_NUM = ep.STU_NUM
THEN ep.enterdatep
ELSE eb.enterdateb
END
END
END AS entrydate
FROM dbo.mx AS mx LEFT OUTER JOIN
dbo.v_EntryDate9_R AS er ON mx.stu_num = er.stu_num LEFT OUTER JOIN
dbo.v_EntryDate9_P AS ep ON mx.stu_num = ep.stu_num LEFT OUTER JOIN
dbo.v_EntryDate9_A AS ea ON mx.stu_num = ea.stu_num LEFT OUTER JOIN
dbo.v_EntryDate9_B AS eb ON mx.stu_num = eb.stu_num

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
Any ideas?

We need to insert data/rows from a SQL Server 2014 database into MS Access database. The problem is, there are so many columns (100+) in the table and there are so many insert transactions of this kind (from different tables) that it is not very easy to write the code in VB.NET that lists all column names.
Both the Access and SQL Server tables have the same number of columns and the equivalent data types, so inserting is not really the problem. It's just that is there a way to do an insert statement in T-SQL that does not name all the columns?

which is to parse a create table script using Microsoft.SqlServer.TransactSql.ScriptDom namespace..I get a list of statements : StatementList SQLStatement = parser.ParseStatementList(StreamReader, out errors);then I cast a relevant statement to the CreateTableStatement type which gives me access to the ColumnDefinition class.
foreach (TSqlStatement T in SQLStatement.Statements)
{ if (T is CreateTableStatement) { CreateTableStatement TC= (CreateTableStatement)T}}
with foreach (ColumnDefinition CD in TC.Definition.ColumnDefinitions)
I am ready to loop through the columns so far so good. I can get to the column name using CD.ColumnIdetifier.Value, to the data type using CD.DataType.Name.BaseIdentifier.Value, but can't seem to get to the length definition. Meaning, I can get column1 , varchar; but I need column1, varchar(40). where do I get (40) from?I tried using ScriptTokenStream under C.DataType, but it seems to iterate through all tokens not just ones relevant to that fragment.

Hello team, I have learned quite a bit from everyone here. I have decided to post a question for you guys and see what the best method is. Our Sr. DBA has asked me to get a list of all of our users permissions on all of our databases. We have about 20 SQL servers some of which have more databases and instances than I have fingers and toes. Can anyone recommend any solution to this problem? Perhaps there is a script I can download/write which will help me on this? Thanks in advance.

I'm got a "folder" structure application which we'll be using as an in-house directory viewer. (In case you're wondering, it doesn't relate to any "real" folders, so using xp_cmdshell is out! )
Each folder and file record can have its own permissions, however these are assumed to inherit from the parent folder if no specific access rules have been set, basically in the same way file systems work. Each file record can only have one parent, and a folder can either have a parent or be at the root level.
Right now I'm having an issue with the inheritance of permissions. Say if I want to grant access to "Folder 1" to "Group A", then "Group B" shouldn't be able to see it. However, if I grant access to "File 1" in "Folder 1" to "Group B", then "Group B" should be able to see "Folder 1", but only see "File 1" and not the rest of the contents.
I thought I could do this with a CTE, but I'm having a bit of difficulty..
Here's the code:
CREATE TABLE #FileSystem (
FSIDINTEGER NOT NULL IDENTITY(1,1) PRIMARY KEY
,ParentFSIDINTEGER NULL
,NameVARCHAR(100)
,RecordTypeVARCHAR(1)-- (F)older, or Fi(L)e

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

Hi
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.
I have used this
SELECT DISTINCT [SFR Rates All].Sorter, [SFR Rates All].SProgram, [SFR Rates All].S_Price, [SFR Rates All].Min_Loan, [SFR Rates All].Max_Loan
FROM [SFR Rates All];
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.
Thanks
Bob

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))

CA10002
CA10003
CA11597
CA11603
CA1001
CA998

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?

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.

I'm trying to re-write my database to de-couple the interface (MS Access) from the SQL Backend. As a result, I'm going to write a number of Stored Procedures to replace the MS Access code. My first attempt worked on a small sample, however, trying to move this on to a real table hasn't worked (I've amended the SP and code to try and get it to work on 2 fields, rather than the full 20 plus).It works in SQL Management console (supply a Client ID, it returns all the client details), but does not return anything (recordset closed) when trying to access via VBA code.The Stored procedure is:-
USE [VMSProd]
GO
/****** Object: StoredProcedure [Clients].[vms_Get_Specified_Client] Script Date: 22/09/2015 16:29:59 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON

I have an SSIS package that moves data from SQL Server to an legacy Access database. In SQL Server, there is a date/time column that I need to split into a separate date column and time column in the access database. Initially I just created a derrived column for the time and set the expression equal to the source date/time column from SQL Server. Unfortunately, that just makes the date column and time column the same having the full date/time.
What expression can I use during a derrived column transformation to assign just the date to a derrived column and just the time to another derrived column?
Thanks,
Steve
