C# 在格式化日期查询数据库
C# 在查询语句中使用格式化函数,格式化日期,将出生日期格式化为“年月日”的格式,后附完整源代码下载,以下是部分代码:
private void Frm_Main_Load(object sender, EventArgs e)
{
OleDbConnection con = new OleDbConnection(//创建数据库连接对象
"Provider=Microsoft.Jet.OLEDB.4.0;Data Source="
+ "db_Test.mdb" + ";Persist Security Info=False");
OleDbDataAdapter dap = new OleDbDataAdapter(//创建数据适配器对象
"SELECT * FROM 员工生日表;", con);
DataSet ds = new DataSet();//创建数据集
dap.Fill(ds, "table");//填充数据表
dgv_Message.DataSource = ds.Tables[0].DefaultView;//设置数据源
}
