![]() ![]() SET = CURSOR FAST_FORWARD FORWARD_ONLY FOR IF OBJECT_ID('tempdb.#tmp0') IS NOT NULL DROP TABLE #tmp0 default bounds for epoch time ( mysql timestamp datatype date = date = '' Then basically the same thing in your procedure. Sp_configure 'Ad Hoc Distributed Queries', 1 install mysql odbc connector drivers ( version 5.1 64-bit in this example ) that match your sql server architectureĮnable ad-hoc distributed queries in the mssql instance.on the mssql server, install visual c++2010 runtimes if they are not already installed. ![]() That aside, here is what I think you are asking me: Also in my case it was only two servers and one database on each, so I did not require a cursor. I should take a step back and advise you do not use a linked server if possible and instead use openrowset in MSSQL for accessing a remote MySQL server because a linked server will gather all the results and filter them locally in tempdb, whereas with openrowset you can filter server side using the remote server rdbms syntax. SET = CONCAT('insert into temp_table_xyz (your, fields) SELECT your, fields FROM `', db_name,'`.`table_name`') WHERE SCHEMA_NAME NOT IN ('information_schema', 'performance_schema', 'mysql','sakila')ĭROP TEMPORARY TABLE IF EXISTS temp_table_xyz SELECT DISTINCT SCHEMA_NAME AS `database` DROP PROCEDURE IF EXISTS `report_db`.`getDbData` ĬREATE PROCEDURE `report_db`.`getDbData`( Instead I would leverage mysql to deal with that heavy lifting then use koolreport for the presentation layer. If its 50 databases in a single instance then I wouldnt use koolreport at all to join all your result sets. I think merging a multidimensional array from 50 different databases sounds like a nightmare. We have explained most of them here but if you have more code examples and techniques in order to do that, you can also contribute here.Depends on whether your databases are in the same instance or different instances in my humble opinion. These were some methods that can be used to iterate over an array of objects in PHP. The while loop will continue until the variable $i is no longer less than the number of students in the array (count($students)). ![]() The code above creates an array of student information, then uses a while loop to print each student's name. While loop will iterate through each element of the array. While loop can be used to loop through an array of objects. Use While loop to loop through an array of object The code above creates an array of student information, then uses a for loop to iterate through the array and print out each student's name. This can be useful when you need to perform an action on each object in the Array, such as displaying data from the object or calling a function that uses data from the object. Here we will describe how to use a For loop to iterate through an array of objects. Loop through Array of Objects using For loop This loop will iterate through each element in the $students array and print out the id, name, and department for each student. The code above is an example of a foreach loop. This is a common operation in PHP when working with arrays of data.Ĭode example 1, "name" => "John", "department" => "Science" ], The below PHP code example shows how to loop through an array of objects using the foreach loop. ![]()
