获取Access用户定义的表名和各表的字段名
public static DataTable GetSchemaTable(string connectionString) //获取Access所有的表名;
{
using (OleDbConnection connection = new
OleDbConnection(connectionString))
{
connection.Open();
DataTable schemaTable = connection.GetOleDbSchemaTable(
OleDbSchemaGuid.Tables,
new object[] { null, null, null, "TABLE" });
return schemaTable;
}
}
private string[] GetTabelName(string conn) //获取Access文件中所有表名,放在数组里面
{
DataTable dt = GetSchemaTable(conn);
int n = dt.Rows.Count;
string[] strTable = new string[n];
int m = dt.Columns.IndexOf("TABLE_NAME");
for (int i = 0; i < n; i++)

用TSQL把Access的表导入到远程Sql Server:
把access 的.mdb里t_itemList 表的数据插入到远程SqlServer的t_itemL1111111表里。
SELECT top 10 * INTO t_itemL1111111 IN [ODBC]
[ODBC;Driver=SQL Server; UID=jyb;PWD=jyb;Server=10.1.18.49;DataBase=所有合并;]

access中时间要用#,不是双引号
select * from kc where rq < #2000-01-01# and rq>#2002-01-01#
不要用between,它的效率泰低
使用# 而不是 ......
查询语句只要这样写,就可以随机取出记录了
SQL="Select top 6 * from Dv_bbs1 where isbest = 1 and layer = 1 order by newID() desc"
在ACCESS里
SELECT top 15 id from tablename order by rnd(id)
SQL Server:
Select TOP N * from TABLE Order By NewID()
Access:
Select TOP N * from TABLE Order By Rnd(ID ......

一、创建一张空表:
Sql="Create TABLE [表名]"
二、创建一张有字段的表:
Sql="Create TABLE [表名]([字段名1] MEMO NOT NULL, [字段名2] MEMO, [字段名3] COUNTER NOT NULL, [字段名4] DATETIME, [字段名5] TEXT(200), [字段名6] TEXT(200))
字段类型:
2 : "SmallInt", // 整型
3 : "Int", ......
