| CqlParameter Properties | 
The CqlParameter type exposes the following members.
| Name | Description | |
|---|---|---|
| DbType | 
            Gets or sets the DbType of the parameter.
              (Overrides DbParameterDbType.) | |
| Direction | 
            Gets or sets a value indicating whether the parameter is 
            input-only, output-only, bidirectional, or a stored procedure return value parameter.
              (Overrides DbParameterDirection.) | |
| IsNullable | 
            Gets a value indicating whether the parameter accepts null values.
              (Overrides DbParameterIsNullable.) | |
| ParameterName | 
            Gets or sets the name of the IDataParameter.
              (Overrides DbParameterParameterName.) | |
| Precision | [Supported in the .NET Framework 4.5.1 and later versions] Gets or sets the maximum number of digits used to represent the Value property.  (Inherited from DbParameter.) | |
| Scale | [Supported in the .NET Framework 4.5.1 and later versions] Gets or sets the number of decimal places to which Value is resolved.  (Inherited from DbParameter.) | |
| Size | 
            The size of the parameter.
              (Overrides DbParameterSize.) | |
| SourceColumn | 
            Gets or sets the name of the source column that is mapped
            to the DataSet and used for loading or 
            returning the Value.
              (Overrides DbParameterSourceColumn.) | |
| SourceColumnNullMapping | 
            Sets or gets a value which indicates whether the source column is nullable.
            This allows DbCommandBuilder 
            to correctly generate Update statements for nullable columns.
              (Overrides DbParameterSourceColumnNullMapping.) | |
| SourceVersion | 
            Gets or sets the DataRowVersion
            to use when loading Value.
              (Overrides DbParameterSourceVersion.) | |
| Value | 
            Gets or sets the value of the parameter. 
            If no type information was provided earlier, the type of the parameter will be
            guessed from the value's type.
              (Overrides DbParameterValue.) |
