Hi,
Can somebody recommend me some optimal values for sort_buffer_size and total ram for a server with 64gigs ram and 15k mysql connections. .

I did some research with few load tests and still seems to be lost on the deciding factor.. it would be great to see some insights from you experts

Hi folks
I want to create a SQL Query, that I am not sure how to deal with it.

there is two table
table_1 should contain some information, but it’s messed up
table_2 contains shared key between table_2 and table_1 and should be filtered by table 2

so I made a filter subquery as
SELECT common_row from db_name.table_1 WHERE company_name LIKE ‘Mc%’

this query gives me list of common_row that I want to use for table_1 (150ish data return)
Now I need to create a insert into clause/statement to use that info.
Let’s say table_1 has (common_row, row_1, row_2, row_3)

I want to add as
INSERT INTO db_name.table_2 (common_row, row_1, row_2, row_3) VALUES
({I have no idea how to put common row in here}, value_1, value_2, value_3),
({I have no idea how to put common row in here}, value_4, value_5, value_6),
({I have no idea how to put common row in here}, value_7, value_8, value_9)
WHERE common_row IN (my filtering subquery);

It sound wrong somehow, any idea?

Hi all
Any idea about this.

There is a SQL Server database named xyz in the Development environment which is a backup of xyz_prod which is in the Production Environment.

I restored the database yesterday to the Dev environment, I want the data that is loaded into xyz_Prod from yesterday to today to be loaded 

into the xyz database in the Dev Environment. This should be carried out on a regular basis

Try to create store procedure that takes record from last 24 hours and schedule this store procedure

Create user ‘username’@’localhost’ identified by ‘password’;

gunnyvenkat:
—- create a procedure with variables :- live table name/staging table name/key column to match records.
—- so that we can join with live and staging table and delete matched records using keys and then insert data from staging to live table
— use dynamic sql

I need to create my own live table and staging table

—- so that we can join with live and staging table and delete matched records using keys and then insert data from staging to live table

I need to create my own live table and staging table

I have developed the below code for PostgreSQL

— Staging table
create table test1 (id int);
— Live Table
create table test2 (id int);

— Dummy records
insert into test1 values (1),(2),(3);
insert into test2 values (1),(3);

— Store procedure
CREATE OR REPLACE PROCEDURE delete_records (v_staging varchar,v_live varchar,v_key1 varchar,v_key2 varchar)
language plpgsql
AS
$$

BEGIN

EXECUTE ‘WITH delete_cte as (DELETE FROM ‘ v_staging ‘ as a USING ‘ v_live ‘ as b WHERE a.’|| v_key1 ‘ = ‘ ‘ b.’ v_key2 ‘ returning a.’ v_key1 ‘) INSERT INTO ‘ v_live ‘ SELECT * FROM delete_cte;’;

END;
$$ ;

— Calling Store procedure
CALL delete_records (‘test1′,’test2′,’id’,’id’);

select * from test2;
select * from test1;

Output:
Live Table
id
—-
1
3
1
3
(4 rows)

Staging Table
id
—-
2
