Question

我需要查看我的c＃程序使用的Access数据库中是否存在表。知道有其他数据库的SQL命令将返回表列表。是否有这样的Access / Jet数据库命令？

Answer 1

尝试GetSchema（）

    connection.ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=c:\\access.mdb";    

    connection.Open();

    DataTable userTables = connection.GetSchema("Tables");

Answer 2

完整代码：Get List of Tables in an Access Database - ADO.NET Tutorials

// Microsoft Access provider factory
DbProviderFactory factory =
    DbProviderFactories.GetFactory("System.Data.OleDb");

DataTable userTables = null;

using (DbConnection connection =
            factory.CreateConnection())
{
    // c:\test\test.mdb
    connection.ConnectionString = "Provider=Microsoft
        .Jet.OLEDB.4.0;Data Source=c:\\test\\test.mdb";

    // We only want user tables, not system tables
    string[] restrictions = new string[4];
    restrictions[3] = "Table";

    connection.Open();

    // Get list of user tables
    userTables =
        connection.GetSchema("Tables", restrictions);
}

// Add list of table names to listBox
for (int i=0; i < userTables.Rows.Count; i++)
    listBox1.Items.Add(userTables.Rows[i][2].ToString())

Answer 3

这样的事情应该可以解决问题。子句Type = 1指定表。请注意，这还将包括结果集中的系统表（它们以前缀“MSys”开头。

SELECT Name FROM MSysObjects WHERE Type = 1

有人为我工作

using (OleDbConnection con = new OleDbConnection(connectionString))
            {
                con.Open();
                DataTable dt = con.GetSchema("Tables");
                var selectNames = dt.Rows.Cast<DataRow>().Where(c => !c["TABLE_NAME"].ToString().Contains("MSys")).ToArray();
                foreach (var item in selectNames)
                {
                     // add names to comboBox
                    comboBox1.Items.Add(item["TABLE_NAME"]);
                }
            }
