SQL database table type not recognised

Question

I'm trying to create a database with a table in it programatically.

C#

SqlCeEngine engine = new SqlCeEngine(connStr);
engine.CreateDatabase();

SqlCeConnection conn = new SqlCeConnection(connStr);
conn.Open();

SqlCeCommand cmd = conn.CreateCommand();
cmd.CommandText = "CREATE TABLE Log(Type string,Rego float)";
cmd.ExecuteNonQuery();

However when I run it I get this error:

>>The specified data type is not valid. [ Data type (if known) = string ]

If I set them both to float it works fine. It also doesn't work for char or text.

If anyone has any idea on the matter it would be most helpful.
Thanks in advance

Solution 1

Have a look at supported types - see here[^]. There is no support for string or char.
Try using nchar or ntext.
