.net - Boolean Data Type Are Not Working In MySQL?
Feb 1, 2011
I am using MySQL 5.5 and i linked it with my ASP.net Application .i added a dataset to link my application within the MySQL stored procedure !!!the problem is when i call any stored procedure which contains BOOLEAN like this one :
I am trying to upload a picture into database using FormView insertItemTemplate. FormView is bounded by objectdatasource.To upload, I placed FileUpload control inside insertItemTemplate.In table the dataType is image.Error:Object of type 'System.Boolean' cannot be converted to type 'System.Byte[]'.
For the life of me, I can't figure out what the problem is with this:
tempData= from a in dx.SomeTable select a; string searchField="ItemName"; string searchString="BoxPkg"; object[] parameters=new object[]{searchField,searchString}; tempData = tempData.Where("@0 like @1", parameters);
I get this error " {"Expression of type 'Boolean' expected"} "
Validate method is supposed to return true/false. The code for Validate method is
<script language="javascript"> function Validate() { var filename = $get('<%= txt_filename.ClientID %>').value; PageMethods.IsValidFile(filename,OnSuccess, OnFailure); // IsValidFile is a Page Method of bool return type } function OnSuccess(result) { if ( !result) { alert('File '+ $get('<%= txt_filename.ClientID %>').value + ' does not exist'); return false; } else { return true; } } function OnFailure(error) { } </script>
My problem is that even after showing the alert 'File somefilename does not exist'. The whole page refreshes (i.e, postback happens)
I have a large existing stored procedure who's interface I cannot change that has several parameters of type boolean. ODP.NET doesn't support a boolean type and I get an error when trying to access this proc via .NET using a different data type.
i am trying to retrieve data from sql database but I get this error: < An expression of non-boolean type specified in a context where a condition is expected, near ')'. > whats this error meaning?
In my VB.Net code I am using boolean type and it is later stored through a stored procedure to a MS SQL database table. I have so far allways been using "int" as the column type in database table because there is no Boolean type to choose from when designing the columns of a table in the MS SQL Express? Is it correct to use the column type int for storing Boolean values?
I have used ASD.NET code using SQL Database for Transaction operation successfully. By changing the Database Code to interface with MYSQL an Error occurs. If I remove the Transaction Code from within the the application, it works OK by displaying the MYSQL data (Read Only) in the layout of the application. I am using Mysql Essential-4.1.22-win32 and MYSQL Connector ODBC-3.51.2. My objective is to EDIT the MYSQL Data.
I have a page which submits a form in my local system but in my production system when i click my submit button it just freezes with the error in my web developer toolbar saying Error: Sys.WebForms.PageRequestManagerServerErrorException: When calling stored procedures and 'Use Procedure Bodies' is false, all parameters must have their type explicitly set.
I'm trying to use the MySQLRoleProvider(MySql.Web, Version=6.2.2.0) with Visual Web Developer 2008.When trying to add a role I get an exception "Table 'test.my_aspnet_applications' doesn't exist"
I have encountered this problem before on a few shared hosts but cant remember the fix. I have spent almost 2 days googling and I have even gone through 2 external hd's of backups of old projects and read the web.configs but I just cant put my find it and I dont think I am googling the correct terms...
I am using Mysql Connector/Net to store asp session state.
The mysql db is on the hosting server ( I have no mysql locally).
Opening a page locally creates a session in the db.
Opening a page on the host does not.
I have seen this issue before but was a long time ago and I have searched a few of the answered questions here but not too extensive, I'm sick of searching.
My Grid is bound to a collection type datasource. When I try to sort the Columns in the Grid I get Javascript error saying sorting event not implemented. Why is the default inbuilt sort functionality not working which worked fine when I directly used a sqlDataSource using smart tag. Do I have to write some code to achieve sorting ?
I have a Gridview on my aspx page that is filtered based on a series of fields. One of these fields is a drop down list 'Status' the options are; 'Read', 'Unread' and 'Both'.
The SQL Stored Procedure expects serveral parameters including a bit parameter for the field 'Read'. If the Drop Down list has Read or Unread in it my Stored Parameter works but if it has Both in I am not sure what to pass to the Stored Procedure to get it to give me all records or basically ignore the Read field.
I'm quite new to ASP.NET programming, so excuse me if my question is dumb.I have the need of showing a grid (A GridView ?) of boolean values. But instead of showing checkboxes, I want to show the cells filled with black (value is true) or white (value is false). I understand I can do that by crafting a TemplateField and changing the style of the cell to select the correct background color and never displaying an actual value. I have not tried but I think it could work. The grid will contains 99% of boolean values and will contain something like 20 rows of 100 columns (2000 cells).
Now I would like to have that grid edited in place at client side, that is with JavaScript, changing the style of the cell when the user clicks on the cell. There would be a submit button somewhere to postback the whole thing.Is that possible ? Any hint for programming it ?Since I have a lot of webforms which needs to display that kind of grid, I would like to go further and design a custom GridView (or other control) that I could install in the toolbox and reuse easily.
I'm sure this is something simple that I have overlooked, but whilst configuring my SQLDataSource, I have tried to add a where statement onto a column in my datatable that has a data type of 'bit'. I have tried typing 'WHERE Answered = "0"' for false and also 'WHERE Answered = "false"'. The data source doesn't return any rows to my detailsview with either statement.
I have a sql server 2008 database table that has a column of type geometry. I am trying to update the data for a record. The data that needs to be inserted into the database is a POINT location that i get off of two text fields on an .NET form. I pass the values into a procedure to update the record. Below is what I have been trying with no luck. The @lat and @long variables I pass into the procedure as type. Does anyone have a good way to update this data? When I try to compile this code it gives the error: "Msg 403, Level 16, State 1, Procedure UPDATE_LAT_LONG, Line 19 Invalid operator for data type. Operator equals add, type equals geometry."
create PROCEDURE [dbo].[UPDATE_LAT_LONG] (@PK int, @lat geometry, @long geometry ) AS BEGIN SET NOCOUNT ON; UPDATE MITIGATION_REPORTING.dbo.MR_MITIGATION SET MR_MITIGATION_LATITUDE_LONGITUDE = '(''POINT('+cast(@lat as geometry)+' '+cast(@long as geometry)+')'')' WHERE MR_MITIGATION_PK = @PK; END
I have a boolean column in a datagrid that I would like to display as red/green image (I have already created these) instead of false/true. Or maybe I could display the "True" in green text and "False" in red text. Can someone point me in the right direction?
I have defined some binary bit columns in an SQL database table to indicate yes/no conditions, but I don't know how to set or reset them. I tried to use "profile.Volunteer = 0;" C# code in an event handler to reset a voluntary state for the Profile table of members, but what I got back was an error message that said, "Constant value '0' cannot be converted to a bool'. So, if a '0' cannot be used to reset a boolean value, what can be used?
I would like to use an eval stmt to return a true/false for the visible property of a HyperLinkField. IF clientComment exists, I would like it to return True, if clientComment is null or "", then would like it to return False.
By default I noticed it already will not show the hyperlink if clientComment is Null, however the bug I'm running into is if the client enters a comment but then later deletes it so it's not null but blank, or "", in which case the HyperLinkField will incorrectly display. Here's my attempt so far but I'm obviously hitting a wall:
Visible='<%# Eval("clientComment")==Null or =="",False) %>'
