SqlParameter.SqlDbType Property

Gets or sets the SqlDbType of the parameter.

[Visual Basic]
Public Property SqlDbType As SqlDbType
[C#]
public SqlDbType SqlDbType {get; set;}
[C++]
public: __property SqlDbType get_SqlDbType();
public: __property void set_SqlDbType(SqlDbType);
[JScript]
public function get SqlDbType() : SqlDbType;
public function set SqlDbType(SqlDbType);

Property Value

One of the SqlDbType values. The default is NVarChar.

Remarks

The SqlDbType and DbType are linked. Therefore, setting the DbType changes the SqlDbType to a supporting SqlDbType.

For a list of the supported data types, see the appropriate SqlDbType member. For more information, see Using Parameters with a DataAdapter.

Example

[Visual Basic, C#, C++] The following example creates a SqlParameter and sets some of its properties.

[Visual Basic] 
Public Sub CreateSqlParameter()
    Dim myParameter As New SqlParameter("@Description", SqlDbType.VarChar)
    myParameter.IsNullable = True
End Sub 'CreateSqlParameter

[C#] 
public void CreateSqlParameter() 
 {
    SqlParameter myParameter = new SqlParameter("@Description", SqlDbType.VarChar);
    myParameter.IsNullable = true;
 }

[C++]

void CreateSqlParameter() 
 {
    SqlParameter* myParameter = new SqlParameter(S"@Description", SqlDbType::VarChar);
    myParameter->IsNullable = true;
 }
