Views with Filter - Problem |
Mon, Aug 17 2015 12:53 AM | Permanent Link |
Martin Pflug | Hi all,
i have a problem with filter on views. For example: i have a table with cars. Now i created a view (in EDBManager) to show only the black cars. - select * from cars where color = 'black' - In my application i connect the view to an EDBTable. And it shows only the black cars. That's OK Now i want to filter only the sportcars. - Table(View).filter := 'typ = 'sportcar'' - - Table(View).filtered := true - Now i have only black sportcars. That's OK But, if i want to go back - Table(View).filtered := false - Now i have all cars in all colors. Where is the view with "only black cars"? That's NOT OK What i am doing wrong? Please give me a help. Many thanks Martin |

Fernando Dias Team Elevate | Martin,
What version of EDB are you using? Also, are you sure that you aren't using the base table instead of the view ? Can we have the CREATE VIEW SQL, as well as the exact OP code you are using to set/unset the filters please ? -- Fernando Dias [Team Elevate] |

Martin Pflug | Fernando,
>> What version of EDB are you using? first i had the problem with 2.18 Build x. Then i updated to the newest 2.19 Build 3 with the same result. >> Also, are you sure that you aren't using the base table instead of the view ? Yes, i'm sure. >> Can we have the CREATE VIEW SQL, as well as the exact OP code you are using to set/unset the filters? I've created the view in EDBManager. But i change it when my application starts. At my first post i used an example. OK, here is (not an example) some code ZENTRA_BASE_SQLQuery.SQL.Clear; ZENTRA_BASE_SQLQuery.SQL.Add('ALTER VIEW GeraetUserView AS'); ZENTRA_BASE_SQLQuery.SQL.Add('SELECT * from geraet where ShowItOnly in (0,102)'); ZENTRA_BASE_SQLQuery.Prepare; ZENTRA_BASE_SQLQuery.ExecSQL; It works fine. I can see that other rows are'nt visible. Also the RecordCount is correct. For the filter i have a lot of code. Here is one: (GeraetTable ist the EDBTable that i have connected with the view) GeraetTable.DisableControls; GeraetTable.Filter := 'geraeteart_id = ' + GeraeteartTableGeraeteart_ID.AsString; GeraetTable.Filtered := true; GeraetTable.EnableControls; It works fine, i have only the filtered rows from the select in the view. And the RecordCount is correct. Unset the filter is only: GeraetTable.filtered := false; And now there are ALL rows visible. And the RecordCount ... show all rows of the table! |

Adam Brett Orixa Systems | Fernando,
Can I suggest that rather than using an EDBTable you use instead an EDBQuery with the SQL.Text = 'SELECT * FROM [YouViewName]' Then try applying the filters and cancel-filters to this Query rather than the table. I use the exact method you describe, but I always use a Query component and it works fine. |

Martin Pflug | Adam,
thank you. I will check this, but i think it's not possible. My application is a really big one and based on a lot of tables. All bound with edbTables, DBGrids, DBFields and so on. |

Terry Swiers | Hi Martin,
> What i am doing wrong? I don’t think you are doing anything wrong as I can reproduce this here on my side. Definitely unexpected behavior. I'll submit a bug report with step by step instructions later today. --------------------------------------- Terry Swiers Millennium Software, Inc. http://www.1000years.com http://www.atrex.com --------------------------------------- |
