Method Detail

main

public static void main(java.lang.String... args)
                 throws java.sql.SQLException

Options are case sensitive.

Supported options
[-help] or [-?]	Print the list of options
[-url "<url>"]	The database URL (jdbc:h2:...)
[-user <user>]	The user name
[-password <pwd>]	The password
[-driver <class>]	The JDBC driver class to use (not required in most cases)
[-sql "<statements>"]	Execute the SQL statements and exit
[-properties "<dir>"]	Load the server properties from this directory

If special characters don't work as expected, you may need to use -Dfile.encoding=UTF-8 (Mac OS X) or CP850 (Windows).

Parameters:: args - the command line arguments
Throws:: java.sql.SQLException - on failure

setErr
```
public void setErr(java.io.PrintStream err)
```
Sets the standard error stream.

Parameters:

err - the new standard error stream

setIn
```
public void setIn(java.io.InputStream in)
```
Redirects the standard input. By default, System.in is used.

Parameters:

in - the input stream to use

setInReader
```
public void setInReader(java.io.BufferedReader reader)
```
Redirects the standard input. By default, System.in is used.

Parameters:

reader - the input stream reader to use

runTool
```
public void runTool(java.lang.String... args)
             throws java.sql.SQLException
```
Run the shell tool with the given command line settings.

Specified by:

runTool in class Tool

Parameters:

args - the command line settings

Throws:

java.sql.SQLException - on failure

runTool
```
public void runTool(java.sql.Connection conn,
                    java.lang.String... args)
             throws java.sql.SQLException
```
Run the shell tool with the given connection and command line settings. The connection will be closed when the shell exits. This is primary used to integrate the Shell into another application.
Note: using the "-url" option in args doesn't make much sense since it will override the conn parameter.

Parameters:

conn - the connection

args - the command line settings

Throws:

java.sql.SQLException - on failure

print
```
protected void print(java.lang.String s)
```
Print the string without newline, and flush.

Parameters:

s - the string to print

run
```
public void run()
```
INTERNAL. Hides the password by repeatedly printing backspace, backspace, >, <.

Specified by:
