    • getWhere

      public static net.sf.jsqlparser.expression.Expression getWhere(net.sf.jsqlparser.statement.Statement parsedStatement)

    • getFrom

      public static net.sf.jsqlparser.statement.select.FromItem getFrom(net.sf.jsqlparser.statement.Statement parsedStatement)
      Extracts the "FROM" clause or the primary table involved in a SQL statement. This method supports SELECT, DELETE, and UPDATE SQL statements.
      Parameters:
      parsedStatement - The parsed SQL statement as a Statement object. This is typically obtained using JSQLParser's `CCJSqlParserUtil.parse`.
      Returns:
      The FromItem representing the "FROM" clause or the main table for the statement. - For a SELECT statement, returns the main FromItem in the "FROM" clause. - For a DELETE statement, returns the table being deleted from. - For an UPDATE statement, returns the table being updated.
      Throws:
      IllegalArgumentException - If the provided statement type is not SELECT, DELETE, or UPDATE.
