Usage

From source file:pl.lewica.util.FileUtil.java

/**
 * Reads contents of a stream (e.g. SQL script) and splits it into separate statements.
 * IMPORTANT: The assumption is the statements are delimited by semicolons followed by new lines.
 * /*from   w ww .j  av a2 s . co  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. 
 * 
 * The method might be useful on Android that is unable to e.g. create multiple tables in one go.
