Class SqlTool

java.lang.Object
org.hsqldb.util.SqlTool

public class SqlTool extends Object
Sql Tool. A command-line and/or interactive SQL tool. (Note: For every Javadoc block comment, I'm using a single blank line immediately after the description, just like's Sun's examples in their Coding Conventions document). See JavaDocs for the main method for syntax of how to run. This class is mostly used in a static (a.o.t. object) way, because most of the work is done in the static main class. This class should be refactored so that the main work is done in an object method, and the static main invokes the object method. Then programmatic users could use instances of this class in the normal Java way.

      public static void main(String[] args)
      A static wrapper for objectMain, so that that method may be executed as a Java "program". Throws only RuntimExceptions or Errors, because this method is intended to System.exit() for all but disasterous system problems, for which the inconvenience of a a stack trace would be the least of your worries. If you don't want SqlTool to System.exit(), then use the method objectMain() instead of this method.

      Parameters:
      arg - Run "java... org.hsqldb.util.SqlTool --help" for syntax.
      Throws:
      SqlTool.SqlToolException - Upon any fatal error, with useful reason as the exception's message.
