ADO.NET :: How To Pass String Values To Parametrized Sql Query In Clause
Sep 14, 2010
I'm using parameterized sql query to get data from database
string query = "Select * from employee where employee_city in (@value)";
strign city ="'NewDelhi','Bangalore','Mumbai'";
I'm using following code to achive this
[code]...
But this is not giving the result. If run the query in SQLServer query window as "Select * from employee where employee_city in ('NewDelhi','Bangalore','Mumbai')", records are there.
But the same query will not return any records from ADO.Net.
SELECT ClientMaster.ClientName,* FROM ProjectMaster LEFT JOIN ClientMaster ON ProjectMaster.ClientCode=ClientMaster.ClientCode WHERE ProjectMaster.RefCode IN (@refcode) AND ProjectMaster.ProjectStatus=@status
@refcode should be able to contain multiple values but how should I pass value to the parameterized query?
I have tried many ways such as @refcode = 'VALUE1','VALUE2', @refcode = VALUE1,VALUE2 but to no avail?
i dont understand where is the problem with my code. i need to pass the request_id to another page but it is always passing the integer values as 0. whenever it comes to pass integer values it is passing it as 0 even if i perform conversion of string to int.
I have some textboxes and radio buttons in my form, and when the user clicks the "Search" button, an SQL select query is run from an SQLDataSource and that query populates a gridview. I want some of the values in these textboxes/radiobuttons to act as search criteria and I'll form a WHERE clause based on what the user typed into them. How do I do this?
I have a the following code to get data from an oracle database using
a parameterized query:
conn = New OracleConnection(connectionstring) comm = New OracleCommand("select name from Cust_name from Name_Table Where last_name = :lastname", conn) parmLastName = New OracleParameter("lastname", OracleDbType.Varchar2) parmLastName.Value = "Jones" comm.Parameters.Add(parmLastName)
I am trying to write an audit that will tell me what users are doing, so I would like to get the actual sql that is submitted. This is just one example of the query, there are many more so I would like to make it as general as possible. I would like to actually see "
select name from Cust_name from Name_Table
Where last_name = "Jones". I know I could just create the text
I have a number of automatically generated data access classes to handle things like inserts & updates. These look like:
cmd.CommandType = CommandType.Text cmd.CommandText = "UPDATE myTable set f1 = :f1, f2 = :f2, f3 = :f3 where id = :id" cmd.Parameters.AddWithValue(":f1", _f1) cmd.Parameters.AddWithValue(":f2", _f2) cmd.Parameters.AddWithValue(":f3", _f3) cmd.ExecuteNonQuery()
If I were to re-write the sql to do what I want, it would look something like
cmd.CommandText = "UPDATE myTable set f1 = pkg.getMyValue, f2 = :f2, f3 = :f3 where id = :id"
Is there any way to do this by setting _f1 to a "special" value, without changing the update SQL or the way the parameters are set? Only in certain cases will I need to set the value of f1 - most of the time, it will be null.
Using .net 2.0, and system.data.oracleclient against oracle 11.
I have a gridview which I connect by C# and SqldataSource. I use asp.net 2.0 - 3.5.
I want to parameterized the queries and how do I do this in the C# file ? how do I set the selectparameters in C# ?. I do not want to do this in the aspx fil.
My code in C# is:
SqlDataSourceMachineName.SelectParameters.Clear(); SqlDataSourceMachineName.SelectCommand = "Select MachineName from tblMachine inner join tblLocation on tblMachine.MachineLocationID = tblLocation.LocationID where tblLocation.LocationName = 'New York' and tblMachine.StatusID = '1'";
I have a label control in an aspx page, can i set value to the label from an handler file? How can i pass the reference of the label through query string?

I have a dynamic gridview which can be used to add new rows of two columns to specify a start date and an end date. I am trying to use a string collection to pass in the output from the textboxes to a parameterized query as shows. I am getting an incorrect syntax near 9 error. How can I make this work? I need to use the stringbuilder.
protected void btnSaveIterations_Click(object sender, EventArgs e) { int rowIndex = 0; StringCollection sc = new StringCollection(); if (ViewState["CurrentTable"] != null) { DataTable dtCurrentTable = (DataTable)ViewState["CurrentTable"]; if (dtCurrentTable.Rows.Count > 0) { for (int i = 1; i <= dtCurrentTable.Rows.Count; i++) { //extract the TextBox values TextBox box1 = (TextBox)Gridview1.Rows[rowIndex].Cells[1].FindControl("start_iteration"); TextBox box2 = (TextBox)Gridview1.Rows[rowIndex].Cells[2].FindControl("end_iteration"); start_date = box1.Text; end_date = box2.Text;...............
i have used a gridview and checkbox to select the items in the gridview....I can select the values easily...when i am selecting one row at a time then using query string i can easily pass the id of the selected row but when i am selecting multiple rows in the field,i dont know how to pass the array of integers[i.e id value to another field]...
here is a part of my code...this is the html code..
I have a row list as [10,20,30] i want to pass the selected row list ie if (20 is selected ill pass that 20 as query string and retrieve the value). and also i want to select the page number too.

I tried var Page=$(".ui-pg-input").val() but it is not firing i think i am missing something out here.
I am trying to set up a page that has two behaviors. I'm seperating them by URL: One behavior is accessed via /some-controller/some-action, the other is via /some-controller/some-action?customize. It doesn't look like the Request.QueryString object contains anything, though, when I visit the second URL...I mean, the keys collection has one element in it, but it's null, not 'customize'. Anyone have any ideas about this or how to enable this. I'd like to avoid manually parsing the query string at all costs :).
basically i have two dropdown boxes to filter data and textbox with stored procedure bound to gridview.i want to be able to query data depending on the selected value passed,either using one or more parameter values.
i would like seperate sqlcommands to chose from depending on which controls i select to pass parameters.
i have included a parameter Select(control id) as this is declared by the wizard for stored procedure.
but i am not sure how it is defined on the page and passed to procedure.
