DataSource Controls :: Specify Size For A Nvarchar(max) Or Varchar(max) Type Of Parameter In ADO.Net?
Mar 4, 2010
I have an output parameter called '@packIds', that I create in ADO.Net using the code below:
SqlParameter packIdPara = new SqlParameter("@packIds", null);
packIdPara.SqlDbType = SqlDbType.VarChar;
packIdPara.Direction = ParameterDirection.Output;
sqlCmd.Parameters.Add(packIdPara);
How will I specify that the parameter '@packIds' is of max size? I cannot find any code for this.

Does 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)?

i want to convert all my database columns whose data type is char,varchar, nchar to nvarchar datatype. But the main problem is that some of my primary key, foreign key columns are also of varchar datatype. So when i try to change their datatypes to nvarchar then i receive the errors related to constraints of Primary Key, Unique Key and indexes. how to change the datatypes to nvarchar after droping the constraints and after changing all constraints will apply again. I also want that no data loss will occur.

I want to grab some values with a form and then do a lookup via a datareader in a data access class (N-Tier).
I want to return a data list and bind that to a form view control.
Here is some code from the DAL, Business object and search form.
The parameterized query doesn't like the data being passed to it from my web page .

I have a few applications/websites running with LINQ to SQL and the other day I decided to go ahead and optimize some of the queries, etc and I found that the size for variable length data types is derived from the parameter value instead of the column actual size? for example a column is defined as nvarchar(30). when I use linq to query that column with a value that's 5 characters long the parameter in sp_executesql will be defined as nvarchar(5)...this causes a major procedure cache bloat even for a small utility site that has a lot of queries is there a way to optimize this?

I'm playing with an EntityDataSource and specifying a simple order by clause containing one column name, for instance "it.[DNS_NAME]".
When I run the following:
[Code]....
I get an EntitySqlException saying that @sort's type is incorrect. It is expecting a Transient.rowtype that matches one of the columns. What is going on here? Order by parameters don't really have a meaningful type other than a string in my opinion. When I try specifying DbType.String instead of TypeCode.String, the same error is thrown.
The exception:
'@sort' is not a member of type 'Transient.rowtype[(SOFTWARE_DSPL_ID,Edm.Int32(Nullable=True,DefaultValue=)),(COMPUTER_NAME,Edm.String(Nullable=True,DefaultValue=,MaxLength=64,Unicode=True,FixedLength=False)),(DNS_NAME,Edm.String(Nullable=True,DefaultValue=,MaxLength=64,Unicode=True,FixedLength=False)),(DIRECTORATE_NAME,Edm.String(Nullable=True,DefaultValue=,MaxLength=24,Unicode=True,FixedLength=False)),(OS_BROAD_CAT_NAM,Edm.String(Nullable=True,DefaultValue=,MaxLength=25,Unicode=True,FixedLength=False)),(OS,Edm.String(Nullable=True,DefaultValue=,MaxLength=64,Unicode=True,FixedLength=False)),(EQP_TYPE,Edm.String(Nullable=True,DefaultValue=,MaxLength=64,Unicode=True,FixedLength=False)),(EQP_PROP_NO,Edm.String(Nullable=True,DefaultValue=,MaxLength=10,Unicode=True,FixedLength=False))]'
in the currently loaded schemas.
How can I dynamically provide the column name to order by?

I'm trying to compare a parameter of type String with a database field of type ntext. Below is my vb code. carDescription is a field in the database table that is of type ntext. The code didn't work because you can't use the equality operator.
Dim carDescriptionLookupCmdString As String = "SELECT carMake FROM car WHERE carDescription = @description"
Dim carDescriptionLookupCmd As New SqlCommand(carDescriptionLookupCmdString, dbConnection)
carDescriptionLookupCmd.Parameters.AddWithValue("@description", description)
Dim reader As SqlDataReader = carDescriptionLookupCmd.ExecuteReader()

I know that varchar(n) in sql server specifies that a variable character of n bytes can be stored But what value of "n" should I choose if I have to store a string of say 100 character in that field. I am not able to decide the size of varchar when creating a table in database when I have to store a string of say 50 characters or string or 100 or say 1000 characters.

I've got an SQL script that fetches results based on the colour passed to it, but unless I set the size of the variable defined as a varchar to (50) no results are returned.
If I use: like ''+@Colour+'%' then it works but I don't really want to use it in case it brings back results I don't need or want.
The column FieldValue has a type of Varchar(Max) (which can't be changed as this field can store different things). It is part of aspdotnetstorefront package so I can't really change the tables or field types.
This doesn't work:
declare @Col VarChar
set @Col = 'blu'
select * from dbo.MetaData as MD where MD.FieldValue = @Colour
But this does work:
declare @Col VarChar (50)
set @Col = 'blu'
select * from dbo.MetaData as MD where MD.FieldValue = @Colour
The code is used in the following context, but should work either way
<query name="Products" rowElementName="Variant">
<sql>
<![CDATA[
select * from dbo.MetaData as MD where MD.Colour = @Colour
]]>
</sql>
<queryparam paramname="@ProductID" paramtype="runtime" requestparamname="pID" sqlDataType="int" defvalue="0" validationpattern="^d{1,10}$" />
<queryparam paramname="@Colour" paramtype="runtime" requestparamname="pCol" sqlDataType="varchar" defvalue="" validationpattern=""/>
</query>
Also I can't set the size in <queryparam paramname="@Colour" paramtype="runtime" requestparamname="pCol" sqlDataType="varchar" defvalue="" validationpattern=""/>

I had to format my hard disk and reinstall the Visual Studio 2005 Enterprise and SQL 2005 Standardprograms.
While my program worked perfectly before and still works ok on my second computer, I get the following error message on the formated computer:
Parser Error Message: Type 'System.Web.UI.WebControls.Parameter' does not have a public property named 'DbType'.
Source Error:
Line 82: <asp:Parameter Name="Olho" Type="String" />
Line 83: <asp:Parameter Name="image" Type="String" />
Line 84: <asp:Parameter DbType="Date" Name="inicio" />
Line 85: <asp:Parameter DbType="Date" Name="termino" />
Line 86: <asp:Parameter Name="pageId" Type="Int32" />
Source File: /0_oserigrafico/Default.aspx Line: 84
In this case I use a datasource control for a datalist and the parameter list is being built ba the system.
The DBType is created for the smalldatetime feild
how do I add the property named 'DbType'.

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".

I am using a viewstate to store the company Ids and splitting at hyphen.
protected void onCompanychange(object sender, EventArgs e) {
ViewState["companyID"] += companydropdown.SelectedValue + "-";
String companyids = ViewState["companyID"].ToString();
string pattern = "-";
company_array = Regex.Split(companyids, pattern);
company_length = company_array.Length;
}
Company array is a string array where i have stored the company ids
the problem is company_array[0] has the initial value of the dropdownlist(company) --select company which is why m getting the error(cannot convert data type nvarchar to int) . I have used the same logic in many places in my project it did not give any error.
int count = 0;
company_length = company_length - 1;
while (count < GridView3.Rows.Count && compid_counter < company_length ) {
cmd = new SqlCommand("insertWorkDetais", conn);
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.AddWithValue("@trainerId",trainerID);
