Databases :: Updating Of Date And Numeric Columns With Null Value?

May 24, 2010

I use VS2005 on Oracle 10gR2. Using

(System.ComponentModel.DataObjectMethodType.Update,

True) to update database row that returns null values from date and numeric columns,Whenever i try to update same row with null (or empty) values on both date and numeric columns, it results in sending '01-Jan-0001' for date column and 0 for numeric column. I want the user to have the options of null or corresponding values for the update.

Forms Data Controls :: When Updating Gridview When Hide Columns Values Turn To Null?

Mar 5, 2010

I am updating a gridview. Problem is that when I hide certain fields that I do not want the user to update, they lose their values ie. the data is wiped out in the field unless I show them on the grid and make them writeable. Is there a property I need to set for the field to retain the value when the grid is updated or is this in the sql statement?

Databases :: MySQL - CSharp To Assign Null Date Time To A Class Field?

Feb 21, 2011

Using MySQL 5.

In my SAP.NEt project, defined a constant:

public static DateTime NullDateTime = DateTime.MinValue;

I have a function:

protected static DateTime GetDateTime(DataRow row, string columnName)
{
return (row[columnName] != DBNull.Value) ?
Convert.ToDateTime(row[columnName]) :
Globals.NullDateTime;
}

In the source code:

public DateTime StationFeedTime{ get; set; }
StationFeedTime = GetDateTime(row, "StationFeedTime");

I ran a SQL to fetch records from MySQL, this field is Time field in MySQL.

Got an exception inside the function:

Unable to cast object of type 'System.TimeSpan' to type 'System.IConvertible'.

Forms Data Controls :: Sort An Unbound DataGridView By Numeric Or Date Value?

Aug 16, 2010

I'm new to DataGridViews. I have successfully created an unbound DataGridView that contains columns of string, numeric and date values, but I can't seem to figure out how to define a column as a numeric or date value--only strings. I have enabled sort on the columns so the user can click on any column to sort by that column. When I click on the numeric column, it sorts like:

12345.56
13.35
1442.22
...

The dates also sort as strings rather than dates.What is the code to change the data type of an unbound DataGridView column? Is it possible? If not, how can I do this with my unbound data?

Databases :: Import From Csv To SQL With >255 Columns?

Nov 12, 2010

I'm writing a reporting tool that, as a starting point, needs to create a DB table from a csv file. This csv file will have been created from exporting data from our old system (with the new system being the reporting tool) and can have up to 300 columns of data. I've been trying as follows:

[Code]....

but am finding that only the first 255 columns get put in. I am assumg that the Jet driver is the one that is limiting the columns, or is there a registry setting somewhere that'll solve it quickly?

Is there another approach that'll work? I've though of the following, but as it'll take a while to recode and test each time I thought I'd ask the experts first!!

BULK INSERT: would mean that I'd need to pre-create the table first, but if the issue is with the Jet driver I'd surely get the same problem? Use a datatable: it seems pretty fiddly and probably a lot slower, but I guess I could read into a dataset and then bind that to a table to insert? Again the table would need to exist and the driver that I use to read from the csv would be the issue? Do it one row at a time in a loop in the code: assuming I can read the file as text, I could then split the data in code into an array and create a insert statement (again to an existing table) for each row. With what could be 1000s of rows I can't imagine that this is the fastest solution!

Access :: Datetime Datatype Updating To Null Or Nothing?

Feb 11, 2010

Passing a null or nothing value to a datatime datatype database field (Access)

I've been all over the internet looking at this and I have tried dozens of methods without success.

I've read a few forums where, some say you can not assign a null value or a nothing value to a datetime datatype field. Then I see others where they say...'I got it to work'.

If this is true (that you can not pass a null value), how come I can create a record in the Access table and not assign a value to this date field? (The field is defined as not required).

Yet, once a value is in the field, I can not update that field back to a null or a nothing value.

So I'm hoping someone has the definitive answer to this.

I am using VB.Net Vs 2003 and updating an Access data base.

I have an update statement (see below) that uses parameters for updating.

what will work, so that I can put back the null or nothing value?

Or if it really can not be done, I guess I'll have to take that as truth.

[Code]....

Databases :: Why Are The Table Columns Different From MySQL Then With MS SQL

Sep 9, 2010

I try to work with MYSql (because it's free) and I saw that the colums are different then when they are exployed in MS SQL?

Why is this? The most strange differents is that in MySQL there is no applicationId in the membership table.

This differents in tables cost me more time to do a export and import from MS SQL to MySQL.

Databases :: MySqlException: Column Cannot Be Null?

Jan 11, 2010

I'm writing a function in "Query Browser" to add some values to a table.

The function should get this value when the stored procedure is called upon, thus te code looks like:

INSERT INTO customer(customer_name, customer_city) VALUES (@customer_name, @customer_city);

But when trying to execute the function, it says "customer_name can't be null"

i thought maybe it just waiting for the values to be sent from .aspx page, but yet again, i get the same error message.
