I'm trying to bind a datagridview to a tableadapter which contains a query that requires parameters (for the WHERE statement of the query). The datasource is a SQL Server database. When I bind the datagridview in design view, it does not let me choose which tableadapter method I would like to use. The way I've been fixing this is to go into the code behind that form, where Visual Studio puts in some auto-generated code that fills a datatable in the dataset and I change the method that it's using there and put in my parameters. I don't think this is the proper way to do it, however, especially because sometimes that code doesn't even get generated! My other solution is to just programatically bind the datagridview to a datatable which I have filled using the tableadapter. This seems like more work than it should be, though.
View 5 RepliesBanging my head against a wall here. I have a query that looks like this.
SELECT FirstName, LastName, Address
FROM Members
WHERE FirstName LIKE 'JOE%'
That works absolutely fine in query wizard and the DataTablePreview data window. However, when I do this.
SELECT FirstName, LastName, Address
FROM Members
WHERE FirstName LIKE ?
I get nothing when I run the fillby method. If I change the LIKE to =.
SELECT FirstName, LastName, Address
FROM Members
WHERE FirstName = ?
Everything works great. I need to get LIKE working though so I can wildcard search.
I'm using the SQL server OLE db connections if that means anything.
UPDATE
Using the LIKE operator doesn't work at all. When I just swap out = for LIKE. Nothing is returned.
I have a data table that looks like this:
USERNAME ICOUNT IAVERAGE DATE_LOGGED
LAGX01 1245 1245 05-07-2012
LAGX02 2211 1422 05-07-2012
LAGX03 1698 1112 05-07-2012
LAGX04 4598 1555 05-07-2012
LAGX05 2589 3245 05-07-2012
LAGX06 3321 1155 05-07-2012

LAGX11 5547 2011 05-07-2012
LAGX12 9456 3459 05-07-2012
Now, I want to execute a sql query that will display the top 5 based on average, so i did this:
SELECT DISTINCT USERNAME,IAVERAGE FROM myTable WHERE IAVERAGE > 0 AND DATE_LOGGED='05-07-2012' ORDER BY IAVERAGE LIMIT 0,5 and the result is:
USERNAME ICOUNT IAVERAGE DATE_LOGGED
LAGX03 1698 1112 05-07-2012
LAGX09 1598 1142 05-07-2012

LAGX01 1245 1245 05-07-2012
LAGX02 2211 1422 05-07-2012
Now, I want to numberize my query result, so it will look like this:
RANK USERNAME ICOUNT IAVERAGE DATE_LOGGED
1 LAGX03 1698 1112 05-07-2012
2 LAGX09 1598 1142 05-07-2012
