Name

SqlDbType [SQL Server only]

Synopsis


SqlDbType dataType = Parameter.SqlDbType;

Parameter.SqlDbType = dataType;

Specifies the SQL Server data type of the parameter, using the SqlDbType enumeration in the System.Data namespace. If this property is set, the value of the Parameter is converted to this type before it’s passed to the data source. The default is a SqlDbType.NVarChar, a variable-length string of Unicode characters.

Example

The following code snippet sets the Parameter.SqlDbType property and then examines the linked DbType. In this case, the linked DbType value is DbType.Int32.

param.SqlDbType = SqlDbType.Int;

Console.WriteLine(param.DbType.ToString());

Notes

Every SqlParameter class includes a DbType property and a provider-specific SqlDbType property. These two properties are linked. When you set the SqlDbType property, the DbType uses a compatible type and vice versa.

For more information about valid SQL Server data types, and their mappings to .NET framework types, see Appendix A.
