View 6 RepliesDoes it make a difference in terms of the actual size of the database if I define one of the columns as nvarchar(100)? If there are restrictions on the form as for how much you can input, let's say 50 characters, does the db save blank spaces from character 51-100 and create a database that is larger than it would be it the column was defined as nvarchar(50)?
View 2 RepliesI have a textbox for a child's name. The user may enter just the first name, first name + middle name, or first name + middle name + last name for their child. How do I separate this string of texts appart so that I can compare it to the parent's last name textbox before inserting into the database? For example, if one part of the three parts in a child's name matches the parent's last name textbox then delete this part out of the child's full name before inserting into the database.

When attempting to place controls in different content areas using Masterpages and trying to use a compare validator, I get the error: Unable to find control id 'txtStartDate' referenced by the 'ControlToCompare' property of 'cvlDate'. I have also attempted to set it within the c# code behind in page load: cvlDate.ControlToCompare = txtStartDate.ID and by using findControl there must be an easy way to achieve this?

View 3 RepliesI am trying to check for a condition such that a date in an input control (textbox) is not greater from a date 1 years from current date(exactly) and also it should not be less than a date 1 year back from current date. for eg. if today's date is "21/dec/1990" then usen cannot enter a date in textbox which is less than 21/dec/89 and it should not be greater than 21/dec/1991. for this i first tried to confirm the greater than condition, i wrote the following code:
<asp:TextBox
ID="TxtSessionFrom"
runat="server"></asp:TextBox>
<asp:CompareValidator
ID="CompareValidator1"
runat="server"
ControlToValidate="TxtSessionFrom"
ErrorMessage="CompareValidator"
Operator="GreaterThanEqual"
Type="Date"></asp:CompareValidator>
CompareValidator1.ValueToCompare=(DateTime.Now.AddYears(1).ToString());
but this gave an error: The value '' of the ValueToCompare property of 'CompareValidator1' cannot be converted to type 'Date'.

On one of our applications we are getting a timeout error on an 'additional details' field in our database, the field type is nVarChar(MAX).
The error seems to be happening when a user enters more than 4000 characters into the additional details field. It is my understanding that this fieldtype can store up to 8gb of data and should be used in stead of the "Text" field type?
We have since limited the user from entering more than 4000 characters via the application, however the DB still contains legacy data - when the 'additional details' with more than 4000 characters is pulled out - "Timeout Error".
note MONTH AND DATES stored in single or double digits as they occur. Unfortunately DATE TIME is stored in NVARCHAR Data type column as 2/9/2010, 22/10/2010 etc. Following UK Date here. It is required to pull the data to COUNT No. of Expired. Obviously below one fails.
