示例1: GetDimensionsOf
public List<Dimension> GetDimensionsOf(string tablename)
{
// the tempTable is used to store the Database-results
DataTable tempTable = new DataTable();
DataTable tempTable2 = new DataTable();
// this list will be filled and returned
List<Dimension> dimensions = new List<Dimension>();
try
{
Open();
// see http://swp.offis.uni-oldenburg.de:8082/display/MPMDoku/Metadaten-Repository for sql-explanation

// Now get the Data than can be filtered later:
MySqlCommand getContentSQL = new MySqlCommand("SELECT * FROM `" + row["ToTable"].ToString() + "` LIMIT 100", Connection);
/*
* This SQL-Command seems pretty unsafe, why so? Well, Oracle lets you use parameters for the WHERE-part of the query,
* however you can't do the same thing for the FROM-part. God knows why.
