/**

 * IMPORTANT: The assumption is the statements are delimited by semicolons followed by new lines.
 * //  ww  w  . ja v  a 2 s .  c o  m
 * If you are using this method to convert a string with multiple SQL queries to individual statements,
 * make sure the semicolon-new line sequence doesn't exist anywhere inside the SQL statements, perhaps
 * somewhere in the middle of long varchars or text fields as they would be treated as SQL statement
 * delimiters and you would therefore get unexpected results.
