有两种方法来为数据库创建一个新表，
1.我们可以用写出并执行T-SQL语句来创建表：
private void CreateTableBtn_Click(object sender, System.EventArgs e)
{
//打开连接
if (conn.State == ConnectionState.Open)
conn.Close();
ConnectionString = "Integrated Security=SSPI;" +
"Initial Catalog=mydb;" +
"Data Source=localhost;";
conn.ConnectionString = ConnectionString;
conn.Open();
sql = "CREATE TABLE myTable" +
"(myId INTEGER CONSTRAINT PKeyMyId PRIMARY KEY," +
"myName CHAR(50), myAddress CHAR(255), myBalance FLOAT)";
cmd = new SqlCommand(sql, conn);
cmd.ExecuteNonQuery();
}
2.我们可以引用SMO库并用SMO函数来创建一个表
private void CreateTableBtn_Click(object sender, System.EventArgs e)
{
// 建立数据库服务器
string connectionString = "...";
SqlConnection connection =
new SqlConnection(connectionString);
Server server =
new Server(new ServerConnection(connection));
// 在我的个人数据库中创建表
Database db = server.Databases["mydb"];
// 建立TestTable的新表
Table newTable = new Table(db, "TestTable");
// 添加主键ID列
Column idColumn = new Column(newTable, "ID");
idColumn.DataType = DataType.Int;
idColumn.Nullable = false;
idColumn.Identity = true;
idColumn.IdentitySeed = 1;
idColumn.IdentityIncrement = 1;
// 添加"Title"列
Column titleColumn = new Column(newTable, "Title");
titleColumn.DataType = DataType.VarChar(50);
titleColumn.Nullable = false;
// 为 Table对象添加列
newTable.Columns.Add(idColumn);
newTable.Columns.Add(titleColumn);
// 为表创建一个主键的索引
Index index = new Index(newTable, "PK_TestTable");
index.IndexKeyType = IndexKeyType.DriPrimaryKey;
// 主键索引包括1列 "ID"
index.IndexedColumns.Add(new IndexedColumn(index, "ID"));
//表中添加一个新的索引.
newTable.Indexes.Add(index);
// 在数据库中实际创建一个表
newTable.Create();
}
