推荐答案
只需使用标准的SQL命令:
Just use standard SQL commands:
DELETE FROM myTable WHERE Id=6
SELECT userName FROM myTable WHERE Id=6
UPDATE myTable SET userName='Joe' WHERE Id=6
INSERT INTO myTable (Id, userName) VALUES (7, 'Mike') (8, 'Jane')
C#代码与MsSql相同,只是您使用SqlCeConnection,SqlCeCommand等.
The C# code is just the same as for MsSql, only you use SqlCeConnection, SqlCeCommand, and so forth.
using (SqlCeConnection con = new SqlCeConnection(strConnect))
{
con.Open();
using (SqlCeCommand com = new SqlCeCommand("INSERT INTO myTable (myColumn1, myColumn2) VALUES (@C1, @C2)", con))
{
com.Parameters.AddWithValue("@C1", myValueForColumn1);
com.Parameters.AddWithValue("@C2", myValueForColumn2);
com.ExecuteNonQuery();
}
}
