2. MSSQL is Coming to Linux Are You Ready? Nem W. Schlecht

3. MSSQL is coming to Linux!! LAMP=
Big things are coming!
MSSQL is coming to Linux!!
LAMP=
Linux
Apache
MySQL/MariaDB/MSSQL
PHP/Perl/Python
Big news!
Microsoft usually doesn’t like support non-Microsoft operating systems

4. So what??? Completely free MSSQL SQL Express Linux VirtualBox
Windows Server 2012 (eval)
VirtualBox + Puppet/Ancible = quick dev environments

5. Some questions… What won’t be there? Clustering
Access to registry values
SSMS (on Linux)
Too reliant on underlying windows OS
VisualStudio on Linux IS a possibility!

6. Most things should work
Some answers
Easy install
apt-get install mssql-server
Most things should work
Replication
Mirroring
HA Backups
Linux has *much* better underlying filesystems

7. Just the database engine
Some answers
Just the database engine
No Reporting Services
No Analysis Services
For now…

9. What about now? What can we do now? Port applications to MSSQL
Access MSSQL from Linux

10. Use linked servers on MSSQL FreeTDS library on Linux
First steps
Use linked servers on MSSQL
Connect to Linux databases
FreeTDS library on Linux
Yes! You can access MSSQL from Linux already!

11. Connect to any DB with an ODBC connector
Linked Servers
Connect to any DB with an ODBC connector
MySQL
PostgreSQL
SQLite

12. Link to external database
Linked Servers
Link to external database
Install DB OBCD driver
Connect to DB
Add Linked Server
Query away

13. Linked Servers
OPENQUERY()
Query external database

14. Linked Servers - SELECT
FROM OPENQUERY(MySQLdb, '
SELECT id , name , age , address
, active
FROM users
WHERE active = "y"
');

15. Linked Servers - INSERT (What?)
INSERT INTO
OPENQUERY(MySQLdb, '
SELECT id , name , age , address
FROM users
WHERE 1=0 ')
VALUES (
'nem'
, 41
, '123 Town Street, Anycity USA, 12345' );

16. Linked Servers - UPDATE
OPENQUERY(MySQLdb, '
SELECT id , name , age , address
FROM users
WHERE name = "nem" ')
SET age = 41;

17. Linked Servers - DELETE
OPENQUERY(MySQLdb, '
SELECT id , name , age , address
FROM users ')
WHERE name = ‘nem’ ;

18. Linked Servers - Copy Table
SELECT name , age , address , active INTO users FROM OPENQUERY(MySQLdb, ' SELECT id , name , age , address FROM users ');

19. Linked Servers - Fun Stuff
Join a MySQL table to an SQLite table
Connect to a MySQL database over an SSH tunnel
Use VIEWs to simplify OPENQUERY

20. Linked Servers - Demo
Demo

21. FreeTDS library Connect to MSSQL Servers from Linux (and Mac) Use: PHP
Perl
Python
Ruby
Command Line Utilities
Bash Scripts

22. FreeTDS Configuration
/etc/freetds/freetds.conf
[global]
tds version = auto
text size = 64512
client charset = UTF-8
[localdb]
host = localhost
instance = MSSQLSERVER
port = 1433
tds version = 8.0

23. FreeTDS Configuration (multiple names)
[localdb]
host = localhost
instance = MSSQLSERVER
port = 1433
tds version = 8.0
[appdevdb]

24. FreeTDS Configuration Instance
[appqadb]
host = localhost
instance = APPQA
port = 14331
tds version = 8.0

25. FreeTDS Utilities tsql defncopy datacopy
Test SQL connection, but can run any SQL
defncopy
Print out CREATE statement for SQL object
datacopy
Copy data between servers

26. FreeTDS Utilities freebcp fisql osql bcp clone Interactive SQL shell
OSQL clone (uses ODBC)

27. FreeTDS Utilities
Demos

28. FreeTDS Library
Uses existing language database API

29. FreeTDS Library API (Perl)
#!/usr/bin/perl use DBI; $db = "nemdev"; my $dbh = DBI->connect("dbi:Sybase:$db" , "$ENV{DBI_USER}" , "$ENV{DBI_PASS}") || die "No DB Connect"; $dbh->do("USE tempdb"); $dbh->do("DROP TABLE test_table"); $dbh->do("CREATE TABLE test_table (test_field VARCHAR(10))");

30. FreeTDS Library API (Perl cont.)
my $sth = $dbh->prepare(" INSERT INTO test_table (test_field) VALUES (?) "); is just some text); for { $sth->execute($_); } $sth->finish();

31. FreeTDS Library API (cont.)
$sth = $dbh->prepare(" SELECT test_field FROM test_table ORDER BY test_field "); $sth->execute(); while = $sth->fetchrow()) { print "Row } $sth->finish(); $dbh->disconnect();

32. FreeTDS Library API (PHP)
<?php $link = mssql_connect('nemdev', 'nem', 'S3cr3t!'); if (!$link) die('Unable to connect!'); if (!mssql_select_db(tempdb', $link)) die('Unable to select database!'); $result = mssql_query('SELECT test_field FROM test_table'); while ($row = mssql_fetch_array($result)) { var_dump($row); } mssql_free_result($result); ?>
