PHP MySQL query using UNIONs and locating which table the data came from

由 拟墨画扇 提交于 2020-01-05 08:55:10
问题 So I have a query that I am selecting values from two different tables and UNIONizing them together. I need to know where which entry came from as I need to form a different URL for each. What is the best way and proper syntax to tag both of these SELECT queries. Any help would be appreciated. Code to follow: $query = "SELECT newsletter_id id, newstitle title FROM tbl_news WHERE (newstitle LIKE '%".stripslashes($rowCont->fname)."%' && newstitle LIKE '%".stripslashes($rowCont->lname)."%') ||

问题 I have two IEnumerable collections that I would like to union. One selects news objects that are associated with a particular category. When a user is filtering by a category I would also like news articles that have been tagged with another category to be displayed. So I have another query that returns news objects that are tagged with the particular sub category. Now I would like to union the two collections, removing duplicates (as a news article associated to the main category, may also

How to combine multiple tables that vary slightly in columns

由 我是研究僧i 提交于 2020-01-03 18:33:11
问题 I have multiple tables where there are roughly 10 common columns, but some tables have 1-2 extra columns. I would like to combine all these tables into one table with a row for each row from each table, with NULL values for any columns that didn't exist in each particular row's source table. So my inputs look roughly like this: table1 id | colA | colB table2 id | colA | colB | colC table3 id | colA | colB | colD And I am trying to get this: allTables id | colA | colB | colC | colD In the

Representing union bitfields using c#'s StrucLayout and FieldOffset

由 回眸只為那壹抹淺笑 提交于 2020-01-03 11:45:32
问题 I understand that in order to represent unions in C# I need to use StructLayout[LayoutKind.Explicit)] and [FieldOffset(x)] attribut to specify the byte offset inside the union. However, I have a following union I want to represent and FieldOffset attrib only offset by size of a byte. union _myUnion { unsigned int info; struct { unsigned int flag1:1 // bit 0 unsigned int flag2:1 // bit 1 unsigned int flag3:1 // bit 2 unsigned int flag4:1 // bit 3 unsigned int flag5:1 // bit 4 unsigned int

LINQ to Objects .Distinct() not pulling distinct objects

问题 I have two ways that I am doing a fuzzy search for a customer. One is by an abbreviated name and the other is by the customer's full name. When I take these two result sets and then union them together (which I have read several places should remove distinct values) I get duplicates. Thinking that all I need to do is then call the .Distinct() method on this, I also still get duplicates. Do I need to implement some compare functionality in my customer object?
