问题 I have a table (AmenityData) of data and a column of this table contains postalsectors e.g. E14 7 I also have an Excel spreadsheet with a list of postal districts e.g. E14 I need to get all the data out of the AmenityData table where the postal districts are LIKE the postal sectors e.g. WHERE [PostalDistricts] + '%' LIKE [PostalSector]. The code i'm using at the moment is not coming up with an error but just returning nothing and i know that there should be plenty of results returned: SELECT

问题 Does the GAE experimental Full Text Search API provide an alternative to the SQL "LIKE statement"? Thanks! 回答1: No. The SQL like statement supports arbitrary substring matching - for instance, "abbatton" will be a match for "bat" - while fulltext search implements full text indexing, which uses normalization, stemming, and an inverted index to construct an index that is good at answering the sort of queries users tend to enter for textual documents. If you mean "does the Full Text search API

问题 I have a database that is supposed to contain all top-level and second-level domain names. But the feed I'm parsing contains a lot of sub folders, I'd like to delete any row that contains any % sign in it, but I am having a hard time figuring out how to use a percent sign as the field I'd like to match, while still using the LIKE feature. Below is the code I'm trying to use: select FROM `001ProductList` WHERE programURL LIKE '%%%' Here is an example of what I'm trying to match: www.site.com

问题 I am attempting to query a table for a limited resultset in order to populate an autocomplete field in javascript. I am, therefore, using a LIKE operator with the partial string entered. If I have, for example, a table such as: tblPlaces id country 1 Balanca 2 Cameroon 3 Canada 4 Cape Verde 5 Denmark For the sake of this example, let's say I want two rows returning - and yeah, for this example, I made up a country there ;) I want to prioritize any instance where a partial string is matched at

问题 I've been racking my brain on how to do this for a while, and i know that some genius on this site will have the answer. Basically i'm trying to do this: SELECT column FROM table WHERE [table].[column] LIKE string1 OR [table].[column] LIKE string2 OR [table].[column] LIKE string3... for a list of search strings stored in a column of a table. Obviously I can't do a like statement for each string by hand because i want the table to be dynamic. Any suggestions would be great. :D EDIT: I'm using

问题 I'm an Android developer and recently came across the GLOB clause in SQLite. I cannot understand why we need GLOB given that LIKE is already in place. Both clauses have wildcards to represent single and multiple characters. The only difference is that GLOB is case sensitive. But is that all? Are there any queries where LIKE is a bad or inappropriate choice? Are there any cases where we absolutely have to use GLOBE vs LIKE or vice versa? 回答1: Case sensitivity is useful by itself, because this

问题 I'm trying to get a query working that takes the values (sometimes just the first part of a string) from a form control. The problem I have is that it only returns records when the full string is typed in. i.e. in the surname box, I should be able to type gr, and it brings up green grey graham but at present it's not bringing up anything uless the full search string is used. There are 4 search controls on the form in question, and they are only used in the query if the box is filled in. The
