Has anyone tried a good, preferably REST API for retrieving quotes It must be able to. Ive been looking briefly at Quotes Daddy, STANDS4 and I heart quotes. For full documentation of the API and to test the API end points from your browser visit Access Quote of the day in various. This page is only for high level reference only. And our easy to use REST style Quotes API gives easy way to access the data. At They Said So we have a huge collection of quotes in our database.
In addition to these functions, the class automatically creates the database connection. New versions of the Joomla Platform API provide additional functionality which extends the database layer further, and includes features such as connectors to a greater variety of database servers and the query chaining to improve readability of connection code and simplify SQL coding.Joomla can use different kinds of SQL database systems and run in a variety of environments with different table-prefixes. 4 Selecting Records from Multiple TablesPlease watched the updated videos index4&listPLdUnWwhvJspZsEs7mCCl6oHvnAp5ZE0aj provides a sophisticated database abstraction layer to simplify the usage for third party developers. Xignite’s futures and options APIs may include option quotes (bid/ask), option chain lookups, open, high, low, close, volume, moneyness.
By chaining these and other method calls, you can create almost any query against your data store without compromising portability of your code.Below is an example of creating a database query using the JDatabaseQuery class. There are also methods such as insert, update and delete for modifying records in the data store. The recommended way of building database queries is through "query chaining" (although string queries are still supported).Query chaining refers to a method of connecting a number of methods, one after the other, with each method returning an object that can support the next method, improving readability and simplifying code.To obtain a new instance of the JDatabaseQuery class we use the JDatabaseDriver getQuery method:$db = JFactory :: getDbo () $query = $db -> getQuery ( true ) The JDatabaseDriver::getQuery takes an optional argument, $new, which can be true or false (the default being false).To query our data source we can call a number of JDatabaseQuery methods these methods encapsulate the data source's query language (in most cases SQL), hiding query-specific syntax from the developer and increasing the portability of the developer's source code.Some of the more frequently used methods include select, from, join, where and order. Using the Joomla database layer ensures a maximum of compatibility and flexibility for your extension.Joomla's database querying changed with the introduction of Joomla 1.6.
$db -> quoteName ( 'a.created_by' ). // Note by putting 'a' as a second parameter will generate `#_content` AS `a` $query -> select ( array ( 'a.*' , 'b.username' , 'b.name' )) -> from ( $db -> quoteName ( '#_content' , 'a' )) -> join ( 'INNER' , $db -> quoteName ( '#_users' , 'b' ). // Order it by the created date. $query = $db -> getQuery ( true ) // Select all articles for users who have a username which starts with 'a'. $db = JFactory :: getDbo () // Create a new query object.
$db -> quoteName ( 'd.id' )) -> where ( $db -> quoteName ( 'b.username' ). $db -> quoteName ( 'a.catid' ). $db -> quoteName ( 'c.user_id' )) -> join ( 'RIGHT' , $db -> quoteName ( '#_categories' , 'd' ). $db -> quoteName ( 'b.id' ).
$rowAnd you can access the individual values by using: $row // e.g. $db -> setQuery ( $query ) $row = $db -> loadAssocList ( 'username' ) print_r ( $row ) Will give (with line breaks added for clarity): => Array ( => 1, => John Smith, => => johnsmith ), => Array ( => 2, => Magda Hellman, => => magdah ), => Array ( => 3, => Yvonne de Gaulle, => => ydegaulle )You can access the individual rows by using: $row // e.g. In this case, multiple select statements can be chained in conjunction with using the second parameter of $db->quoteName. ' DESC' ) Notice how chaining makes the source code much more readable for these longer queries.In some cases, you will also need to use the AS clause when selecting items to avoid column name conflicts.
To retrieve the number of rows affected by a INSERT, UPDATE, REPLACE or DELETE query, use getAffectedRows(). To get a result from getNumRows() you have to run it after the query and before you have retrieved any results. $row->emailMiscellaneous Result Set Methods getNumRows()GetNumRows() will return the number of result rows found by the last SELECT or SHOW query and waiting to be read. $db -> setQuery ( $query ) $row = $db -> loadObjectList ( 'username' ) print_r ( $row ) => stdClass Object ( => 1, => John Smith, => stdClass Object ( => 2, => Magda Hellman, => stdClass Object ( => 3, => Yvonne de Gaulle,And you can access the individual values by using: $row->column_name // e.g. But if it does not have a unique value you may not be able to retrieve results reliably.LoadAssocList('key', 'column') returns an associative array, indexed on 'key', of values from the column named 'column' returned by the query.
Quotes Database Api Zip File To Install
The method Factory::getUser() returns the user object of the currently logged-on user, or if not logged on, then a blank user object, whose id field is set to zero.The $db->replacePrefix((string) $query) expression returns the actual SQL statement, and outputting this can be useful in debugging.Zip up the mod_db_select directory to create mod_db_select.zip.Within your Joomla administrator go to Install Extensions and via the Upload Package File tab select this zip file to install this sample log module. ' ASC' ) $db -> setQuery ( $query ) echo $db -> replacePrefix (( string ) $query ) $results = $db -> loadAssocList () foreach ( $results as $row ) The code above selects and outputs the username and email of the records in the Joomla users table, apart from those of the currently logged-on user. $db -> quote ( $me -> id )) -> order ( $db -> quoteName ( 'name' ). If you are unsure about development and installing a Joomla module then following the tutorial at Creating a simple module will help.Important note: In any Joomla extensions which you develop that you should avoid accessing the core Joomla tables directly like this and should instead use the Joomla APIs if at all possible, because the database structures may change without warning.In a folder mod_db_select create the following 2 files: getQuery ( true ) $query -> select ( $db -> quoteName ( array ( 'name' , 'email' ))) -> from ( $db -> quoteName ( '#_users' )) -> where ( $db -> quoteName ( 'id' ). If you run getNumRows() after loadRowList() - or any other retrieval method - you will get a PHP Warning:Warning: mysql_num_rows(): 80 is not a valid MySQL result resourceIn libraries\joomla\database\database\mysql.php on line 344 Sample Module CodeBelow is the code for a simple Joomla module which you can install and run to demonstrate use of the JDatabase functionality, and which you can adapt to experiment with some of the concepts described above.
