• FreeTDS is a free implementation of the TDS (Tabular Data Stream).
• Includes three client libraries: DB-Library, CT-Library, and ODBC
• To use tsql : $ sudo apt-get install freetds-bin

Free TDS

$ wget http://ibiblio.org/pub/Linux/ALPHA/freetds/stable/freetds-stable.tgz
$ tar -zxvf freetds-stable.tgz
$ cd freetds-0.91/

Configuration

#./configure --with-tdsver=7.0 --prefix=/usr/local/freetds
#make
#make install
#export SYBASE=/usr/local/freetds
#export LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:/usr/local/freetds/lib 

Instalation

Forma 1:

   # apt-get install unixodbc unixodbc-bin
   Estos comandos instalara esto:
   	/etc/odbc.ini
   	/etc/odbcinst.ini

Instalar tdsodbc

$ apt-get update
$ apt-get install tdsodbc

Este comando instalara esto:

	/usr/lib/x86_64-linux-gnu/odbc/libtdsodbc.so
	/usr/share/tdsodbc/odbcinst.ini

drivers for both FreeTDS and ODBC in a single package

Tenemos varias formas de instalar freetds

Automatico

$ apt-get install freetds-bin

Manualmente

ftp://ftp.freetds.org/pub/freetds/stable/ descargar la version deseada

# wget ftp://ftp.freetds.org/pub/freetds/stable/freetds-1.00.9.tar.gz
# tar xvfz freetds-stable.tgz
# cd freetds-0.82
# ./configure --with-tdsver=5.0 --with-unixodbc=/usr
# make
# make install
# make clean

	Si durante la instalacion de freetds manual, se da estos mensajes :
	- No acceptable C compiler found in $PATH when installing python
		redhat base: # yum groupinstall "Development tools"
		Debian base: # apt-get install build-essential
	- configure: error: sql.h not found
		sudo apt-get install unixodbc-dev
	- freetds all-recursive error 1
	$ sudo apt-get install libtool autoconf 
	$ autoreconf -f -i

=== Configuracion ===
	- freetds-dev does not include tsql

Show configure

```bash
$ tsql -C

These commands connects me to the database:

$ tsql -S MyServer -U username@servername -P password
$ tsql -S serverhost -U dbowner -P dbpassword
$ sqsh  -S serverhost -U dbowner -P dbpassword 
$ tsql -LH
