47. Motivation
Thousands of Web Services that provide valuable
data
Requires developers to read documentation and form
URLs/queries.
Data is isolated
Needs combining, tweaking, shaping even after it
gets to the developer.
48. YQL
SQL-Like Language
Synonymous with Data access
Familiar to developers
Expressive enough to get the right data.
Self Describing - show, desc table
Allows you to query, filter and join data across
WebServices.
49. YQL Statement Basics
Verbs
show: lists the supported tables
desc: describes the structure of a table
select: fetches data
use: use an Open Data Table *new*
show tables
desc social.contacts
51. YQL Statement Basics
Syntax -> Select -> Collection
FROM collection
Yahoo! WebServices
Social Dir, Upcoming, MyblogLog,
Y!Local, Search(BOSS)
External DataSources
XML, Atom, RSS, JSON, CSV, HTML
52. YQL Statement Basics
Syntax -> Select -> WHERE clause
Table data can be filtered in the WHERE
clause either
Remotely by the table data source
Locally by the YQL engine (dot
notation)
53. YQL Statement Basics
Syntax -> WHERE clause -> Remote Filter
WHERE <remote_key>=‘value’
Tables require Keys in where clause
Specified in the describe
<query>
<key name=”guid” required=”true” .../>
</query>
Correspond to query, path or matrix
parameters for the Endpoint
54. YQL Statement Basics
Syntax -> WHERE clause -> Local Filter
WHERE <local_filter> OP ‘value’
Filter an element or an attribute
<movies> Dot notation:
<movie>Star Wars</movie> movies.movie LIKE ‘%Star%’
<movie>StarTrek</movie>
</movies>
<, >, =, LIKE, matches, not matches,
not like
AND, OR binary operator combinations
55. YQL Statement Basics
Syntax -> Select -> Projection
SELECT <what>
Uses the dot notation to project
parts of matching item(s)
<results>
<movie>
<id>101</id>
Projection: (relative to root)
<name>Star Wars</name>
select movie.id, movie.name
</movie> from ...
<movie>...</movie>
</results>
56. YQL Statement Basics
Syntax -> Select -> Sub-Select
IN (SELECT ...)
Join across data sources
field IN (select guid from ...)
Like SELECT but can return only
N leaves
Get the profile for all my connections:
select * from social.profile where guid in
(select guid from social.connections where owner_guid = me)
57. YQL Statement Basics
Syntax -> Select -> Sub-Select
IN (SELECT ...)
(field, ...fieldN) IN (SELECT
f1,...fn from table)
Get the Location name of the given Photo:
select place.name from flickr.places where (lat, lon) in
(select location.latitude, location.longitude from
flickr.photos.info where photo_id='3030238604')
58. YQL Statement Basics
Syntax -> Select -> Table Size
Changing the Table Size
Yahoo! Tables are limited to a
small number by default (10)
select * from local.search where zip=‘94089’
and query=‘pizza’
Increase set size as parameters
to Collection
select * from local.search(100) where
zip=‘94089’ and query=‘pizza’
59. YQL Statement Basics
Syntax -> Post Query Manipulation
Post Select processing using
‘pipe’ symbol.
select ... | sort(field=‘item.pubDate’)
select ... | unique(field=‘item.title’)
select ... | tail(count=10)
Functions operate on return data.
Operations unrelated to table or
data source.
60. YQL Statement Basics
Syntax -> YQL Variables (@var)
Like Prepared Statements for YQL
Substitutes Query parameter
http://<>?q=....&city=Bangalore&state=Karnataka
select * from table where city=@city and state=@state
Can be used in sub-selects
select * from table where city in (@city, @city2,
@city3)
61. YQL Statement Basics
Syntax -> YQL Variables (@var)
Multi Valued variables
http://<>?q=....&city=Bangalore&city=Mumbai
select * from table where city in (@city)
76. Open Data Tables
Schema defines mapping between YQL
and Endpoint
Keys can either be query, path or
matrix parameters
Keys can be marked as required
YQL Compiler validates existence
of required keys
77. USE Verb
use ‘http://url-to-def.xml’ as tableName;
select * from tableName where key=‘value’...
Imports the Table defintion
Makes it available to following
statements as tableName
desc tableName - describes the def
Acts like a First Class Data
Source just like other YQL Tables.
