我在我的项目中使用Jackcess来连接MS Access数据库,但我找不到删除表的方法。
如何使用杰克塞斯删除表?
Database db = null;
try
{
db = Database.open(FileLocations.getCache());
Table table = db.getTable("refNum");
//table.delete(); //trying to achieve
}
catch (IOException ex)
{
Logger.getLogger(TheDatabase.class.getName()).log(Level.SEVERE, null, ex);
}
finally
{
try
{
db.close();
}
catch (IOException ex)
{
Logger.getLogger(TheDatabase.class.getName()).log(Level.SEVERE, null, ex);
}
}
以下代码似乎可以解决问题:
Database db = DatabaseBuilder.open(new File("C:/Users/Public/mdbTest.mdb"));
Table tbl = db.getSystemTable("MSysObjects");
Cursor crsr = tbl.getDefaultCursor();
Map<String, Object> findCriteria = new HashMap<String, Object>();
findCriteria.put("Name", "refNum");
findCriteria.put("Type", (short)1);
String status = "";
if (crsr.findFirstRow(findCriteria)) {
tbl.deleteRow(crsr.getCurrentRow());
status = "table dropped (row deleted from MSysObjects)";
}
else {
status = "row not found in MSysObjects";
}
System.out.println(status);
db.close();
