Example:
\open
Basically, there are five commands a user should know:
\provider, \connectionstring, \open, \quit, and \help
To connect to a database, you need to do the following:
1. set your data provider via \provider
Example:
SQL# \provider mysql
2. set your connection string via \connectionstring
Example:
SQL# \connectionstring Database=test
3. open a connection to the database via \open
Example:
SQL# \open
Example:
SQL# \ConnectionString Database=testdb
or
SQL# \cs Database=testdb
For more examples, see section CONNECTION STRING EXAMPLES.
Example: to set the provider for MySQL:
SQL# \provider mysql
or
SQL# \p mysql
Note: if you need to load an external provider in SQL#,
see the SQL# command \loadextprovider
Example:
SQL# \ListProviders
or
SQL# \listp
Example:
SQL# \bcs
ConnectionString Option: Data Source [] SQL# blazer
ConnectionString Option: Persist Security Info [False] SQL#
ConnectionString Option: Integrated Security [False] SQL#
ConnectionString Option: User ID [] SQL# scott
Password: *****
ConnectionString Option: Enlist [False] SQL#
ConnectionString Option: Pooling [True] SQL#
ConnectionString Option: Min Pool Size [0] SQL#
ConnectionString Option: Max Pool Size [100] SQL#
ConnectionString Option: Unicode [False] SQL#
ConnectionString Option: Load Balance Timeout [0] SQL#
ConnectionString Option: Omit Oracle Connection Name [False] SQL#
ConnectionString is set.
Example: to load the MySQL provider Mono.Data.MySql
SQL# \loadextprovider Mono.Data.MySql Mono.Data.MySql.MySqlConnection
Example:
SQL# \open
Example:
SQL# \close
Example:
SQL# \defaults
Example:
SQL# \q
e execute SQL query (SELECT)
Example: to execute a query
SQL# SELECT * FROM EMPLOYEE
SQL# \e
Note: to get \e to automatically work after entering a query, put a
semicolon ; at the end of the query.
Example: to enter and exectue query at the same time
SQL# SELECT * FROM EMPLOYEE;
Example: to insert a row into a table:
SQL# INSERT INTO SOMETABLE (COL1, COL2) VALUES('ABC','DEF')
SQL# \exenonquery
Note: this can be used for those providers that are new and do not have
the ability to execute queries yet.
Example: to execute a Maxium aggregate
SQL# SELECT MAX(grade) FROM class
SQL# \exescalar
Example:
SQL# SELECT fname, lname, hire_date FROM employee
SQL# \exexml employee.xml
Note: this depends on DataAdapter, DataTable, and DataSet
to be working properly
Example:
SQL# \f batch.sql#
Note: the SQL# commands are interpreted as they are read. If there is
any SQL statements, the are executed.
Example:
SQL# \o result.txt
Example:
SQL# \load commands.sql
Example:
SQL# \save commands.sql
Example:
SQL# \h
Example 1:
SQL# \s true
Example 2:
SQL# \s false
Example:
SQL# \r
Example:
SQL# \print
SH VARIABLES WHICH CAN BE USED AS PARAMETERS
Commands to set variables which can be used as Parameters in an SQL statement. If the
SQL contains any parameters, the parameter does not have a variable set, the
user will be prompted for the value for each missing parameter.
Example:
SQL# \set sFirstName John
Example:
SQL# \unset sFirstName
Example:
SQL# \variable sFirstName
If this option is true, the SQL contains parameters, and for each parameter which does not have a SQL# variable set, the user will be prompted to enter the value For that parameter.
Example:
SQL# \useparameter true
Default: false
Example:
SQL# \usesimplereader true
Default: false. Mostly, this is dependent on the provider. If the provider does not have enough of IDataReader implemented to have the normal reader working, then the simple reader can be used. Providers like SqlClient, MySQL, and PostgreSQL have this ption defaulting to true.

The latest version can be downloaded from http://npgsql.projects.postgresql.org/ MySql.Data is the MySQL Connector/Net for connecting to MySql databases. For MySQL, it is strongly recommend to use MySql.Data instead of the old ByteFX.Data provider. Unfortunately, MySql.Data is not included with Mono. You can download the latest MySQL Connector/Net from MySQL AB at http://dev.mysql.com/downloads/ FirebirdSql.Data.Firebird can be downloaded from here: http://www.firebirdsql.org/index.php?op=files&id=netprovider
Example of usage:
\connectionstring Database=testdb
Connection String examples:
Microsoft SQL Server via System.Data.SqlClient
Server=DANPC;Database=pubs;User ID=saPassword=;
For Integrated Security, bear in mind that Mono is not
integrated with Windows, SQL Server client nor server, nor
Windows Server. Therefore, you must provide the Windows Domain
name and domain user name and password for this user.
Server=DANPC;Database=pubs;User ID=DOMAINser;Password=pass;Integrated Security=SSPI
For a server locally, you can use localhost.
ODBC via System.Data.Odbc provider using
a DSN named "MSSQLDSN" I set up
in the Windows control panel's ODBC Data Sources
which connects to Microsoft SQL Server 2000:
DSN=MSSQLDSN;UID=danmorg;PWD=freetds
To use ODBC ON Unix, consider unixODBC from http://www.unixodbc.org/
or use iODBC from http://www.iodbc.org/
SQL Lite via Mono.Data.SqliteClient
provider which connects to the
database file SqliteTest.db; if not found,
the file is created:
URI=file:SqliteTest.db
Oracle via System.Data.OracleClient
Data Source=testdb;User ID=scott;Password=tiger
If you prefer to not use a tnsnames.ora file, you can
use a connection string which allows a
TNS network description that is parentheses delimited
like the following which has the host, port, and
service name. For host, you can specify an IP address
instead of a hostname.
User ID=SCOTT;
Password=TIGER;
Data Source=(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=192.168.1.101)(PORT=1521))(CONNECT_DATA=(SERVER=DEDICATED)(SERVICE_NAME=TESTDB)))
Npgsql (.NET PostgreSQL) from
http://gborg.postgresql.org/project/npgsql/projdisplay.php
Server=localhost;Database=test;User ID=postgres;Password=fun2db
ByteFX (ByteFX MySQL) from
Please use MySql.Data instead.
