SYNOPSIS

odbcinst action object options

action is one of

-i

install a driver or data source

-u

uninstall a driver or data source

-q

query a list of drivers or data sources present on the system

-j

print config info

-c

call SQLCreateDataSource

-m

call SQLManageDataSources

--version

shows the version number of the program

object is one of

-d

an ODBC driver in /etc/odbcinst.ini

-s

an ODBC Data Source Name (DSN) in an odbc.ini file.

options are zero or more of

-f template file

Used with -i, this option specifies a template file containing the driver or DSN to be installed.

-r

Read the template from standard input.

-n Driver/Data Source Name

Used with -u to specify a driver or DSN to remove.

-v

Contrary to standard practice, this turns off verbose output; there is no output, even for errors.

-l

The specified Data Source object is a System DSN, in /etc/odbc.ini.

-h

The specified Data Source object is a User DSN, in the current user's $HOME/.odbc.ini. This is the default with -s.

DESCRIPTION

odbcinst updates the configuration files that control ODBC access to database servers on the current host. It also maintains in /etc/odbcinst.ini a count of the number of references to a particular driver, which can be used to determine whether it should be removed from the file (only when the reference count drops to 0).

Installing

Drivers and DSNs are installed using the -i option.

If the object to be installed is a driver (-d), the specified driver is added to /etc/odbcinst.ini or its reference count is incremented if it is already there.

If the object is a data source (-s), the data source is added either to /etc/odbc.ini (if -l is used) or to $HOME/.odbc.ini (the default, which can also be specified with -h).

Uninstalling

Uninstalling a driver is done with the command odbcinst -u -d -n driver name. Uninstalling a DSN is done with the command odbcinst -u -s -n data source name. Uninstalling causes the reference count on the object to be decremented. If nothing else has requested this driver or DSN (i.e., the reference count drops to zero), it is removed from the config file.

The options -l and -h are used with -s to specify which odbc.ini file to configure.

Queries

The command odbcinst -q -d returns a list of all drivers present in /etc/odbcinst.ini. The command odbcinst -q -s returns a list of all system and user DSNs available.

TEMPLATE FILES

A typical driver template looks like this:

 [MySQL]
 Description     = MySQL driver
 Driver          = /usr/lib/odbc/libmyodbc.so
 Setup           = /usr/lib/odbc/libodbcmyS.so

A DSN template looks like this:

 [Sample DSN]
 Description         = Test MySQL connection
 Driver              = MySQL
 Trace               = Yes
 TraceFile           = /tmp/odbc.log
 Database            = junk
 Server              = localhost
 Port                = 3306
 Socket              = 

The Description and Driver fields should be present in all DSN configurations. Other options are driver-specific; consult your ODBC driver's documentation for a list of allowed options, or see ODBCConfig(1) for a graphical tool that can be used to interactively set up a DSN or driver the first time.

FILES

/etc/odbcinst.ini, /etc/odbc.ini, $HOME/.odbc.ini
