Question

I’d like to build a ParameterCollection object based on the results of either execute sp_columns MyTableName or SELECT * FROM INFORMATION_SCHEMA.Columns WHERE TABLE_NAME = 'MyTableName'.

The problem I’m having is assigning the appropriate data type to each Parameter … I’m unsure of how to gather that information from either of the above two queries and convert it into a System.Data.DbType or System.TypeCode.

Any help is greatly appreciated.

Edit: I guess what I’m looking for is functionality similar to Type.GetType("TypeName") that would accept a SQL data type. For example, DbType.GetType("int") or DbType.GetType("varchar").

Answer 1

It’s actually really easy to do 🙂 SqlDbType is an enum, and there’s a nice static function on the Enum class which accomplishes just what your looking for:

 private  SqlDbType ConvertType(string typeName)
 {
      return (SqlDbType)Enum.Parse(typeof(SqlDbType), typeName, true);
 }

With this, you should have no trouble converting the output from your INFORMATION_SCHEMA query into a collection of SqlParameters.
