1,查詢表名集合
SELECT name FROM sqlite_master
WHERE type='table'
ORDER BY name;
2,編程語言遍歷刪除
public static bool deleteAllData()
{

try
{

DataSet ds = new DataSet();

if (ds != null && ds.Tables[0].Rows.Count > 0)
{
using (conn = SqliteHelper.GetConnection())
{
var cmd = new SQLiteCommand(conn);
//開始事務
trans = conn.BeginTransaction();
//while (dr.Read())
for (int i = 0; i < ds.Tables[0].Rows.Count; i++)
{
string dSql = "delete from " + ds.Tables[0].Rows[i][0].ToString();
cmd.CommandText = dSql;
cmd.ExecuteNonQuery();
}
//提交事務
trans.Commit();
Console.ReadLine();
//ds.Close();
//成功標識
res = true;
}
}
}
catch (Exception ex)
{

}
finally
