Alternative to multi-valued fields in MS Access

Related question: Multivalued Fields a Good Idea? I know that multi-valued fields are similar to many-to-many relationship. What is the best way to replace multi-valued fields in an MS Access application? I have an application that has multi-valued fields. I am not sure how exactly to do away with those and implement exactly same logic in the form of fields that are single-valued? What would be the implementation in terms of table-relationships when I want to move a multi-valued relationship to single-valued one. Thank you. Fionnuala The following is probably far more detailed than you need,

Is there any workaround for sorting on multiValued field?

Sorting can be done on the "score" of the document, or on any multiValued="false" indexed="true" field provided that field is either non-tokenized (ie: has no Analyzer) or uses an Analyzer that only produces a single Term (ie: uses the KeywordTokenizer) docs:- http://wiki.apache.org/solr/CommonQueryParameters#sort My original schema is (You can consider the following is a GROUP-BY) :- products (id, unique) users who make some comments(multiValued) last_comment_date for each user (multiValued, one user can make multiple comments, but only the last comment date is captured) If sorting on

Reporting Services - Multi-value parameter query returning no results

核能气质少年 提交于 2019-12-02 02:00:37
Using SSRS (SQL Server 2005) I've set up two reports. For ease of explanation, let's call them MAIN_REPORT and SUB_REPORT . MAIN_REPORT runs a query that returns a set of Areas, with multiple TagNames per area: AREA Tagname ---------- A1 T1 A1 T2 A2 T3 A3 T4 If you select one of the Area cells, it opens SUB_REPORT and passes a parameter to @ParentTagNames using Join(Parameters!ResultsOfSearch.Value,",") . ResultsOfSearch is equal to the Tagname column above (haven't yet figured out how to limit the Tagnames to only the ones in the selected area, but I'll worry about that later). SUB_REPORT

Break atomicity rule storing list of items when there is no reason to query about items? Verses join table that requires whole join table be scanned

This specific case is regarding lists, and items. The same item may belong to multiple lists, and each list has many items. Option A (the "proper" way as I understand it): Make a join table, which has list_ID and item_ID. When I want all the items in a list query for list_ID. Option B (break the atomicity rule): Make a list table. Primary Key, and either repeating columns or non-atomic columns. As I understand it both of these deviations suffer the exact same drawbacks, which is the inability to inefficiently query on items. As I understand it, normalizing a database to NF-1 would be making

SSRS Multi Value Parameter. Check whether “Select All” is selected

拥有回忆 提交于 2019-11-30 17:58:48
I have a multi value parameter in my SSRS Report. I want to find out whether (Select All) is checked in that parameter. In other words, whether all the values in the parameter are checked or only some values are checked. Is it possible? I am able to find out number of selected values through Parameters! Parameter .Count. Is there a way to find out total of items in that parameter? In case anyone is still having issues doing this, I just coded this easy fix. =IIF(COUNTROWS("dataset").Equals(Parameters!parameter.Count),"it is equal","this is not equal") For the specific use-case of showing the

Bound combobox items refers to different field items

*爱你&永不变心* 提交于 2019-11-28 14:23:44
I got a bounded combobox to a group name in vb.net. i can view in the drop down items of the combobox the set of GROUP NAMES. but when i do an insert or update query, i need to make the selected group name refers to the GROUP NUMBER. I don't want to store letters in the database, instead i prefer numbers. how can i do that?! Here is my code so far : cmd1.Parameters.AddWithValue("@group", DirectCast(Additemcombobox.SelectedItem, DataRowView).Item("GroupName")) Storing the group name in database is currently working well. My question might not be well explained. Please ask me in case... any help

MySQL procedure to load data from staging table to other tables. Need to split up multivalue field in the process

偶尔善良 提交于 2019-11-28 06:10:31
问题 I'm trying to export data from a multivalue database (Unidata) into MySQL. Lets say my source data was a person's ID number, their first name and all the states they've lived in. The states field is a multi value field and I'm exporting them so that the different values within that field are seperated by a ~. A sample extract looks like: "1234","Sally","NY~NJ~CT" "1235","Dave","ME~MA~FL" "3245","Fred","UT~CA" "2344","Sue","OR" I've loaded this data into a staging table Table:staging Column 1:
