SQL Query - Searching Database Using Filters?

Aug 4, 2010

I'm currently searching a database using filters. The user can use any or all of them, and to achieve this, I have the following

Private Sub GetData()
Dim QueryString As String = "SELECT * FROM Inventory WHERE"
Dim FiltersExist As Boolean = False
'Set Up Connection to Database
[Code] ....

I would like to create this using the query builder instead, but I don't know how to tell it to ignore a parameter if its value is null or an empty string. Another problem with the way I'm doing it now is that if the user has filtered the results, then adds a record, I cannot use the Update method of my TableAdapter, because the datasource of my DGV has changed. Even if I can't achieve what I want with the Query Builder.

Heres a snippet of my

Sheet1BindingSource.Filter = "Make like '" & MakeIDComboBox.SelectedItem & "'"

Query For Searching Customer ID?

Jan 20, 2011

I'm currently in the middle of attempting to create a query that will be used so that the application user will be able to search the a customers id number. I'm completely new to adding queries using the query builder so I've become slightly stuck on trying to get this to work corrently.

I have a database which is set up and in this case the table is called 'cid' which defines the customers id column in the database, this is a primary key and the column has a data type 'AutoNumber'. I've become stuck as I'm not sure what I would have to put into the filter to make this query work.

Access Database And Using A Parameter Query With The LIKE Operator To Return All Rows That Match Query?

Apr 28, 2010

I am connecting to an Access database and using a parameter query with the LIKE operator to return all rows that match query. The string to search for is taken from a Textbox

sql =

"Select * FROM Allview WHERE Info Like" &
"*" &
CStr(TextBox1.Text) &
"*"
The query does not return any data in vb, but when run from access with same string, there is data returned.The connection to the database is done correctly, as I am able to return data with various other queries.

Partial code :

Searching A Database With Use Of The 'LIKE' Statement?

Apr 3, 2009

I am currently trying to develop a program, for personal use, that will monitor the lending of items of music equipments to friends and family etc. And, for my program, I have a requirement, which is the ability to search a relational database, for items loaned, through my program, based on criteria entered in a set of text boxes located upon the program's form. I have already set up the form, and have searched the Internet high and low, to no avail (probably didn't look hard enough).e,I would also like to make another request... if possible I would like to achieve this task with use of the 'LIKE' statement, so that I don't have to input the criteria in full, when I wish to search the database.

The database that I am using is a standard Microsoft Office Access database, saved in a '.mdf' format, and the database comprises of three tables; LoanTbl (which specifies the loan details), EquipTbl (which contains information about the equipment loaned) and a LinkTbl (which forms the relationship between these former two tables) - the reason for the LinkTbl, even though it may seem unnecessary, is because the data has undergone 'normalisation', so that it is stored in the most efficient way possible.

Also, whilst I am on the point of linking together my program and database, does anyone also possibly have any ideas as to ways in which to add data to this relational database; I do have coding for this, however, it only applies to a stand-alone table, whereas there are relationships between my tables.

VS 2008 Searching A .mdb Database?

Jun 11, 2009

how to add and remove entries from a database and now I need to know how to search it. I'm going to be scanning a directory and subdirectories and adding all files found to the database. I need to check if the file has already been entered into the database before adding it.

I though it'd be simple and would just require looping though each entry and checking the item for each entry. I played around with a while loop a bit and ran into some problems. Like when the database is empty.

I don't want to half-ass some code that seems to work, since that'd probably be slow and inefficient.

Also what are the technical terms for a column and row in a database. I'd to use the proper terms in the future.

Searching Data In An Access Database?

Apr 28, 2011

I know how to search for one specific number from a single line in an access database using a query, but now I have to search through a whole database and display each instance. Ex) I search the number "1" in column "1" of the database and it has "2" instances. So now I have to take the corresponding data in the rows next to it in order to display them in the label.

search: "1", both results are ID = "1"

results:
dates amount
10/13/2009 $43.00
12/25/2009 $86.00

I know how to put the results for "1" line of a database into the .item field, but im confused on how to search multiple lines of a database and store multiple items. Heres what I have so far...
