Java syntax conventions

This book uses these font and syntax conventions for Java items:

• Classes, interfaces, methods, and packages are shown in bold Helvetica within paragraph text. For example:

  SybConnection class

  SybEventHandler interface

  setBinaryStream( ) method

  com.Sybase.jdbx package

• Objects, instances, and parameter names are shown in italics. For example:

  "In the following example, ctx is a DirContext object."

  "eventHdler is an instance of the SybEventHandler class that you implement."

  "The classes parameter is a string that lists specific classes you want to debug."

• Java names are always case sensitive. For example, if a Java method name is shown as Misc.stripLeadingBlanks( ), you must type the method name exactly as displayed.

Transact-SQL syntax conventions

This book uses the same font and syntax conventions for Transact-SQL as other Adaptive Server documents:

• Command names, command option names, utility names, utility flags, and other keywords are in bold Helvetica in paragraph text. For example:

  select command

  isql utility

  -f flag

• Variables, or words that stand for values that you fill in, are in italics. For example:

  user_name

  server_name

• Code fragments are shown in a monospace font.Variables in code fragments (that is, words that stand for values that you fill in) are italicized. For example:

  Connection con = DriverManager.getConnection         ("jdbc:sybase:Tds:host:port",  props);

• You can disregard case when typing Transact-SQL keywords. For example, SELECT, Select, and select are the same.

Additional conventions for syntax statements in this manual are described in Table 0-1 . Examples illustrating each convention can be found in the System Administration Guide.

Syntax statement conventions

Key	Definition
{ }	Curly braces indicate that you choose at least one of the enclosed options. Do not include braces in your option.
[ ]	Brackets mean choosing one or more of the enclosed options is optional. Do not include brackets in your option.
( )	Parentheses are to be typed as part of the command.
|	The vertical bar means you may select only one of the options shown.
,	The comma means you may choose as many of the options shown as you like, separating your choices with commas to be typed as part of the command.
