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#

SQL EXECUTION COMMANDS

Commands to execute SQL statements

.TR 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')

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.

	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:

NAME VALUE to set an internal variable.


Example:
	SQL# \set sFirstName John

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:

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=DOMAINuser;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
