Gail Shaw Microsoft Certified Master: SQL Server, MVP, M. Hopefully you dont need to adjust any timeouts and your sql is fast because cursors unfortunately are not, but I coded this one to be optimized and run as quick as possible with forward only. The syntax for creating a temp table is almost the same as for a user table. Then you would call the mssql stored proc in koolreport in your setup. Where cast(' + + ' as DATE) >= CAST(t0.from_dt as DATE) and cast(' + + ' as DATE) <= CAST(t0.to_dt as DATE) '') NEXT FROM into * from #tmp0 ,'' select t0.your, t1.fields from this_table t0 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 Heres my query: SET FolderId 7 CREATE TEMPORARY TABLE FolderStructure ( id int, name varchar (255) ) WHILE (FolderId > 0) DO INSERT INTO FolderStructure SELECT folders.id, folders. 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 I have a simple temporary table and a while loop that checks a variable value then inserts data into said table.Check the previous rowspan value to avoid printing a value that should not (because the previous one had a rowspan > 1) Here is some code with example values so that you can test it. on the mssql server, install visual c++2010 runtimes if they are not already installed. As you want to change the rowspan, you have to do 2 things : Check the next values in that column to know how many are the same.If you have rights in the database to create tables, then you can use an example like this to create a permanent table. However, to create permanent tables you must have special rights in the database. That aside, here is what I think you are asking me: SQL automatically creates the table based on the column names and data types from the Query results. 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. ![]() To use the function, when you want to reference an array, send it in. I think merging a multidimensional array from 50 different databases sounds like a nightmare. This is a handy function I put together to allow variable variables to be used with arrays. When I try to get the data back from the table I get an error: 42601 ERROR: query has no destination for result data Hint: If you want to discard the results of a SELECT, use PERFORM instead. The following SQLiteCreateTable class demonstrates how to create new tables in the phpsqlite database.Depends on whether your databases are in the same instance or different instances in my humble opinion. I am creating a temp table, and am fetching data from multiple tables and inserting data into it. ![]() We will reuse the SQLiteConnection class that we developed in the previous tutorial. create proc newp as begin declare a int set a5 create table temp(a int) while a >0 begin drop table if exists temp create table temp(a int) set a a-1 end end Command(s) completed successfully. Second, execute the CREATE TABLE statement by calling the exec() method of the PDO object. ![]()
