[英]Deleting records from the created form in c#
我正在使用c#,在此我想删除表单中的记录,我有以下代码..
private void button3_Click(object sender, EventArgs e)
{
OleDbConnection con = new OleDbConnection();
con.ConnectionString = "PROVIDER=Microsoft.Jet.OLEDB.4.0;Data Source=C:\\Documents and Settings\\mayur patil\\My Documents\\Dairy_db\\tblCompany.mdb";
con.Open();
string sql = "DELETE FROM tblCompany WHERE (CoCode = 1)";
}
但我没有得到答案......
您需要设置OleDbCommand
您的案例的完整代码,
private void button3_Click(object sender, EventArgs e)
{
OleDbConnection con = new OleDbConnection();
con.ConnectionString = "PROVIDER=Microsoft.Jet.OLEDB.4.0;Data Source=C:\\Documents and Settings\\mayur patil\\My Documents\\Dairy_db\\tblCompany.mdb";
string sql = "DELETE FROM tblCompany WHERE (CoCode = 1)";
con.Open();
OleDbCommand cmd = new OleDbCommand(sql, con);
cmd.ExecuteNonQuery();
con.Close();
}
有关整个实现的更多信息,请阅读http://www.java2s.com/Code/CSharp/Database-ADO.net/DeletedatabaserecordsthroughOleDbCommandandverifytheresults.htm
