怎样把可以使用的表名输出到一个选择框?
How to put all the table names available in a select box?
问:
I have found out this :-
procedure TForm1.ComboBox1Change(Sender: TObject);
begin
Session.GetTableNames(ComboBox1.Text,'', False,False,ComboBox2.
Items);
Table1.DatabaseName := ComboBox1.Text;
end;
However, GetTableNames also return a query. so, when the user click on
the query, the program crashed...
答:
You seem a little confused between Databases and Tables.
In Delphi, a database refers to a collection of tables, and typically
refers to a directory.
First get a list of databases
Session.GetAliasNames(AliasComboBox.Items);
Now get the tablenames using the selected Alias
Session.GetTableNames(AliasComboBox.Text,'*.db',
False,False,TableComboBox.Items);
Then set the DataBaseName and TableName properties
Table1.DatabaseName := AliasComboBox.Text;
Table1.TableName := TableComboBox.Text;
