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

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#

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

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

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

f
FILENAME to read a batch of SQL# commands from file
Example:
        SQL# \f batch.sql#

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

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=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
