String Searching - Find Records That Does Not Have This List Of Strings In

Jun 12, 2011

I have a problem finding strings that do not exist in a column in a database. I am going to use linq but its more the 'way' of doing I am concerned with.

I have strings like;
MEAL
GPST
EXLEG
EXLG ...etc

I need to find records that does not have this list of strings in, so for example DBML BUT sometimes I can have the string MEALDBML, or more concatenated. So this is a known string of MEAL and unknown string of DBML. I would then want to see that record. I do not know the unknown strings up front, so its a case of feeding in the strings I know are ok, and finding one that are outside that list. I was also thinking of regex?

I need to do a query in which I can find all records in a table in which a user enters a search word. The word to be searched for will be a word in a column.

.net - Write A Linq To Sql Query To Find Records Where Field Name Can Match One Of Dynamic Number Of Strings?

Mar 21, 2012

I have users check off lab facilities in a UI. I want to use linq to fetch corresponding records for all of the labs that they have checked off. Basically,

Dim myRecs = (From l As EpiData In myDataContext.EPIDatas Where l.facility= _
one of the checked labs

So basically, I need to write a linq query where the "strings" to match are determined at runtime. Is there any way to do this easily? I know that there is a library out there called dynamic LINQ, but (1) it's in C# and I'm writing in VB (2) I'm really just looking for a single, simple solution for this single case.

VS 2010 Records In Table Are Determined By Records In Another Table?

Apr 22, 2012

I have a database with 3 tables: Student, Unavailability and Duty.The fields for Student are entered in a form I have. One of the fields in Unavailability is filled by a form, the other fields are an autonumber and a foreign key to the Student table.ow I want records in the Duty table to be created and automatically filled in depending on what the values of the fields are in the Student table.For example, If the Boarder field in the Student table is 'yes' then I want the Duty Number field in the Duty table to be '1', '3' and '4'. If it is 'no' then I want the value to be '2' and '5'. I recognize it will have to create several different records to incorporate the different duty numbers for each StudentID. Obviously this will require an if statement, however this is my first time implementing a database with my limited experience with programming and Visual Basic, so I don't know how to refer to the specific fields in a table and set the value of other fields depending on the data in other fields.

VS 2010 2 Ways Of Reading All Records - Which One Is Best And Why

Oct 17, 2010

I have come up with this 2 methods of reading all records on a database table. Both work nice but I would like your expert opinion on which delivers best performance and why.We are reading table "DATA" and filling an array called lstData with the contents of the "Data" field.

1) Method one is using the bindingsourse to go through all the records.

[code]...

My guess is that the first method, while simpler to the eye could use more overhead. What I really would like to know is if the second method really delivers better performance and if it is worth doing all the manual SQL queries.

I have a database (SQL Server 2008) with multiple tables and records. 1 Table contains all kinds of invoice items, which have a unique id, Client ID and invoice number.

My goals is as following:

- The datagrid should only contain the invoices for a specific client.
- Should add up totals (Amount paid, Amount not paid, Amount Overdue, Total Amount)
- Should be withing specific date range.

Everything in this table has been saved as varchar except invoice id and unique.

VS 2010 : Comparing SQL Records Versus Calendar?

May 2, 2011

I have a program that backs-up remote locations to a centralized FTP server. Upon successful completion, a record is written to a SQL database with the following information:

GUID (uniqueidentifier)
StoreID (varchar(5))
DateStamp (sqldatetime)
ProgramAndVersion(varchar(50))

I am currently managing the program by running a report on who has written a record to the database. If the record is not written, I manually go in and backup the necessary files.The problem with this, is that it can take up to 30 minutes/day to do this task. While that's not a long time, it's getting somebody to be dedicated when I'm off and that has proven to be difficult.

I want the program to automatically search for missing records, but I'm not sure how to do this. I was thinking about bringing in the last 30 days with a SELECT statement and then comparing the information that I have in the SQL database versus a calendar control (or something). I need to make this process completely automated and not very intensive on the SQL server. I only have the following

2010
Sub FindMissingBackups(ByVal DaysToCheck As Integer, ByVal StoreNumber As String)
Dim TodaysDate As SqlDateTime = Now()
Dim PastDate As SqlDateTime = DateAdd(DateInterval.Day, -DaysToCheck, Now())
