I currently am implementing a search bar for one of my apps and I am having a problem with the indexed search overlapping it. I need to move the search field a little to the left so that way the index search is completely visible and not overlapping my search bar. I have tried a few things in interface builder but nothing is working. If ...

I have a merge statement that needs to compare on many columns. The source table has 26,000 rows. The destination table has several million rows. The desintation table only has a typical Primary Key index on an int-type column. I did some selects with group by to count the number of unique values in the source. The test part of the Mer...
Hi, I've been searching for an answer, but no luck so far... I want to perform bulk operations on a database with potentially millions of records, reading the PostgreSQL guide: '13.4 Populating a Database' 1, it suggests removing indexes and foreign-key constraints to speed up the copy operation. I'm trying to accomplish this using JDB...

What is the best way to create an SQL index in SQL database? CREATE INDEX idx ON sometable (col1, col2, col3); Or CREATE INDEX idx1 ON sometable (col1); CREATE INDEX idx2 ON sometable (col2); CREATE INDEX idx3 ON sometable (col3); Which is the difference between these 2 methods? Does it depends on the SQL implementation? (SQLite, M...
I know that .index() will return where a substring is located in python. However, what I want is to find where a substring is located for the nth time, which would work like this: >> s = 'abcdefacbdea' >> s.index('a') 0 >> s.nindex('a', 1) 6 >>s.nindex('a', 2) 11 Is there a way to do this in python? ...
Index Organized Tables (IOTs) are tables stored in an index structure. Whereas a table stored in a heap is unorganized, data in an IOT is stored and sorted by primary key (the data is the index). IOTs behave just like “regular” tables, and you use the same SQL to access them. Every table in a proper relational database is supposed to ha...
Hi I've imported 6K categories and 16K products to magento using a custom import profile. When I'm trying to reindex everything works except for 'Catalog URL Rewrites' that keep showing PROCESSING but never completes. log and exceptions files don't show anything. Is there something I can do to make the index work? Can I just ignore th...
I have an ActiveRecord model like this: create_table "books" do |t| t.string "title" end class Book < ActiveRecord::Base default_scope :order => 'lower(title) DESC' end As you can see I want to sort by the lowercase form of the title attribute, but this imposes a performance hit at the database level. This hit can be remedied in ...
Hi. Say I have a table on an Informix DB: create table password_audit ( username CHAR(20), old_password CHAR(20), new_password CHAR(20), update_date DATETIME YEAR TO FRACTION)); I need the update_date field to be in milliseconds (or seconds maybe - same question applies) because there will be multiple updates of the pa...
I have a mysql table (articles) with a nested index (blog_id, published), and performs poorly. I see a lot of these in my slow query logs: - Query_time: 23.184007 Lock_time: 0.000063 Rows_sent: 380 Rows_examined: 6341 SELECT id from articles WHERE category_id = 11 AND blog_id IN (13,14,15,16,17,18,19,20,21,22,23,24,26,27,6330,6331,...

I know, that this type of indexes exist in Oracle. Old versions on MySQL can not create function-based indexes (thanks, google). And new versions? How about PostgreSQL, SQL Server etc? ...
Hi all I am trying to eak out a bit extra performance from some sql queries which have a where clause on a field which is a non-unique non-clustered index, it is also a foreign key in table A. That foreign key is the primary key on table B and is the clustered index. What I'm wondering is, will I get a performance gain if I add a join ...
Hi I have a table in SQL Server with the following columns: id int (primary key) text nvarchar(max) (full text indexed) type int and I have queries like this: where Contains([text], @text) or where Contains([text], @text) AND [type] = 3 However the second query is slow. I think I should integrate full text index with [type] fie...
