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
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
                
Note: if you need to load an external provider in SQL#, 
      see the SQL# command \loadextprovider 
      

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.

mysqlnet maps to mysql above.
odbc is treated as an external provider for .NET 1.1 and above.
msodbc is an external provider for compatibility with .NET 1.0
MySql.Data has replaced the mysql provider.  If you still need to use ByteFX.Data, then
use bytefx.
MySql.Data is not included with Mono.  You need to 
download the MySQL Connector/Net from MySQL AB at
