How do I run Access queries from within VB? The queries have been written and saved in Access using SQL, and use a search-parameter (Team name) to return a single integer value (games won, points scored etc).
View 1 RepliesI have developed a small ms-access based software with vb.net.
I've added auto-update capabilities to the software (mostly by using clickonce) to simplify the release of new features.
Every version of the software executes the update routine which may update also the existing database.Lately i've made few changes on the database structure adding few stored queries, so i want the autoupdate code to programmatically add these new queries to the existing database and make it perfectly up to date.
I haven't already found a solution to add stored queries to an ms-access database using odbc...I also tried to use the "CREATE PROC" sql statement but it does not seem to work with access databases, even if i create the query form the Microsoft Office Access front-end.I've found some examples that uses ADODB, but i'm using odbc to remain both x86 and x64 compliant.
is there a way to run a query that already exists in an access database?

I have an Access database with some table and some queries.Here you see one query which returns 2507 records:I also added this database to a vb.net project.However, if i try to fill the datatable of the query with the specific tableadapter, the datatable stays empty. Also when I click the query in the dataset and choose 'preview data' I get none of the 2507 records:Any idea why he won't load the records into the dataset?
View 2 RepliesI have an access 2003 database file with hundreds of queries. I would like to rename all tables referenced from within my queries based on a condition
If tableNameInQuery = "tableName" Then
tableNameInQuery = "newTableName"
End If
I would like to be able to run a query that could tell me where a given table/query is used within all of my queries. I would like to do this with SQL but VBA is also fine.

my problem now i guess is 2 fold, i wish to combine the first 3 queries into a single query and place in a list or a collection or is there a way to do this with a single query that will give me my desired result?
Is this possible programmatically? Getting the names of stored queries or checking if a query with a specific name exists?
View 3 RepliesWhile I have no problem to to program the output of two queries into 2 separate Excel workbooks and worksheets via
DoCmd.OutputTo acOutputQuery, "QueryA", acFormatXLS, "filenameQueryA", True
DoCmd.OutputTo acOutputQuery, "QueryB", acFormatXLS, "filenameQueryB", True
I have tried without success to find the right VBA commands within MS Access to create and save only one file with two worksheets, one for each query.
I have written a program that queries an sql database displays it in a detailed listview, no problems so far. The only problem I am running in to is when I got to print the listview. When I do a regular printdocument.print() It prints out the listview exactly how I have it set up to do so. Which is a title , then column headers, next comes the listview, and then a total of some the columns. When I do a printpreview everything looks great. When I click the print button within the printpreviewdialog only the Title, Column headers, and the totals print. [code]

I am getting error "Local variable 'query' is already declared in the current block. (BC30288)".I understand that I am using same name for the object variable for performing subsequent query. Is there a way in which I can dispose the variable completely and reuse it again for querying the new required WMI detail? My search in the net couldn't give me any clue as of how to clear the variable and use it again. The issue is with two variables "query" and "searcher". Is it only possible that I should give unique names to each query object variable as I might add more queries later on?
i'm new at vb.net (though i have extensive vb6 experience and oracle experience), and i need a sample program/project which uses multiple queries (of the same oracle database namespace) to display counts in text boxes.user will use a pull down list to select action from there.
View 1 RepliesI have an access database that has nested queries.

I have a program where a lot of the required information for it is stored in text files. I simply read this information into large arrays. However, I don't think it's necessary to load all the information each time. Rather, it would be more efficient if I could simply search through a list of items to find the one I need and then use the data from it, or to find a similar name and use it elsewhere.
Would I be right in using a database? And is database programming done in SQL? I have a book on it telling me to use the SQL Server (IIRC), so I shouldn't be doing it in the VB.NET Express GUI?
Here's an example of what I would do:
Hex = 03 00 => dex number 003
Search in file Pokemon Dex Numbers
003 returns Bulbasaur
Check Bulbasaur base stats in the base stats file
etc
So basically I'm reusing a lot of information. I think a database would be best and it would all be internal right? I'm getting complaints about access denied to a text file (since it's stored in the program directory in the program files).
So to cap up the few questions I have:
-Databases are done in SQL and not inside the GUI?
-Databases would load internally?
-I could search a database without having to load it into like an array or something?
I have a few questions reguarding converting a Access program to a sql/vb.net program. I know these are vague questions, so feel free to give vague answers.
NOTES: I have a solid unstranding of SQL and VB.net. i have little Access experience, but i would be working with the individual who created the access program. I also don't have alot of experience in converting on program from one language to another. Most of my experience is in new programing.
[Q1] Is their a general rule of thumb when converting/recodeing on how long it should take? i.e. if this project would take me 40 hours to write my self from scratch it would take me 30 hours to recode into another language?
[Q2] What type of problems do i need to look out for when working on projects of this nature and being inexperinced?
I have a Access 2003 backend db and I'm using vb 2005 to connect to the db via conntection string. It works ok! I can see all the tables but only some of the queries. Why should some queries be absent? In 1 query I have a user define function which cuts up a string. I've created a new VB project with a new connection but the same result. I've compacted the database with not change.

View 4 RepliesI've been going through a lot of forums and see a lot of mention of ADO.NET and how it's better to use. I guess because it's newer and being maintained with current times?I've done google searches for this, but every time I see different programming languages other than VB.NET implementing param queries with ADO.net, or it brings me to results that have oledb commands again.Is there a good ADO.NET for VB.NET tutorial with parametrized queries?
