NAME

sqlsharp − Mono SQL Query command-line tool

SYNOPSIS

sqlsharp [−f filename] [−o filename] [−s]

DESCRIPTION

sqlsharp is a Mono SQL tool used for entering SQL queries to a database using Mono data providers.

OPTIONS

The following options are supported:
-f filename

Output file to load SQL commands from.

-o filename

Output file to send results.

-s

Silent mode.

HOW TO USE

The SQL tool accepts commands via its command line interface. Commands begin with a backslash followed by the command name.

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

CONNECTION AND PROVIDER COMMANDS

These commands are used to setup the provider, connection string, and open/close the database connnection
ConnectionString

Sets the Connection String

Example:

		SQL# \ConnectionString Database=testdb
		or
		SQL# \cs Database=testdb

For more examples, see section CONNECTION STRING EXAMPLES.

Provider

Sets the Provider of the Data Source. For list of Providers, see section PROVIDERS.
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

ListProviders

List ADO.NET 2.0 Providers available

Example:

		SQL# \ListProviders
		or
		SQL# \listp

BCS

Prompts you for building each connection parameter and builds the connection string and also allows you to enter a password wich does not echo.

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.

LoadExtProvider

ASSEMBLY CLASS to load an external provider. Use the complete name of its assembly and its Connection class.

Example: to load the MySQL provider Mono.Data.MySql

SQL# \loadextprovider Mono.Data.MySql Mono.Data.MySql.MySqlConnection

Open

Opens a connection to the database

Example:

SQL# \open

Close

Closes the connection to the database

Example:

SQL# \close

Default

show default variables, such as, Provider and ConnectionString.

Example:

SQL# \defaults

Q

Quit

Example:

SQL# \q

SQL EXECUTION COMMANDS

Commands to execute SQL statements

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;

exenonquery

execute a SQL non query (not a SELECT)

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.

exescalar

execute SQL to get a single row and single column.

Example: to execute a Maxium aggregate

		SQL# SELECT MAX(grade) FROM class
		SQL# \exescalar

exexml

FILENAME to execute SQL and save output to XML file

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

FILE COMMANDS

Commands for importing commands from file to SQL# and vice versa

f

FILENAME to read a batch of SQL# commands from file

Example:

SQL# \f batch.sql#

Note: the SQL# commands are interpreted as they are read. If there is
any SQL statements, the are executed.

o

FILENAME to write result of commands executed to file.

Example:

SQL# \o result.txt

load

FILENAME to load from file SQL commands into SQL buffer.

Example:

SQL# \load commands.sql

save

FILENAME to save SQL commands from SQL buffer to file.

Example:

SQL# \save commands.sql

GENERAL PURPOSE COMMANDS

General commands to use.

h

show help (all commands).

Example:

SQL# \h

s

TRUE, FALSE to silent messages.

Example 1:

SQL# \s true

Example 2:

SQL# \s false

r

reset or clear the query buffer.

Example:

SQL# \r

print

show what’s in the SQL buffer now.

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.

set

NAME VALUE to set an internal variable.

Example:

SQL# \set sFirstName John

unset

NAME to remove an internal variable.

Example:

SQL# \unset sFirstName

variable

NAME to display the value of an internal variable.

Example:

SQL# \variable sFirstName

PROVIDER SUPPORT OPTIONS

Enable or Disble support for a particular provider option
UseParameters

TRUE,FALSE to use parameters when executing SQL which use the variables that were set.

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
UseSimpleReader

TRUE,FALSE to use simple reader when displaying results.

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.

NOTES:

Ngsql is the .Net Data Provider for PosgreSQL. The
latest verison 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

CONNECTION STRING SAMPLES

Example connection strings for various providers to be used via the command \ConnectionString

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.
	Server=localhost;Database=test;User ID=mysql;Password=

FirebirdSql via FirebirdSql.Data.Firebird (download latest form FirebirdSql.org)

Database=C:\FIREBIRD\EXAMPLES\EMPLOYEE.FDB;User=SYSDBA;Password=masterkey;Dialect=3;Server=localhost

MySQL via (MySql.Data) MySQL Connector/Net from http://www.mysql.com/

Server=localhost;Database=test;User ID=mysql;Password=mypass;Pooling=false
