Return Boolean — true if the cursor is on a valid row; false if the cursor is positioned before the first row. JdbcRef — The value of the designated column in the current row of this result set as a reference. Throws: SQLException - if the columnIndex is not valid; if a database access error occurs or this method is called on a closed result set Since: 1. Retrieves the number, types and properties of this ResultSet object's columns. An application may want to call refreshRow when caching or prefetching is being done by the JDBC driver to fetch the latest value of a row from the database.

    That is, if a record in the ResultSet is changed in the database by another thread or process, it will be reflected in already opened ResulsSet 's of this type.

    Thus, you can iterate through it only once and only from the first row to the last row. The text about queries shows how the result of a query is returned as a java.

    For example, calling the method absolute -1 positions the cursor on the last row; calling the method absolute -2 moves the cursor to the next-to-last row, and so on. The ResultSet interface also contains a set of methods you can use to inquire about the current position of the ResultSet.

    ResultSet setFetchSize int. Moves the ResultSet to point after the last row in the ResultSet. Updates the designated column with a String value. There are a lot of getXXX methods you can call, which return the value of the column as a certain data type, e.

    This tutorial explains how to work with the Java JDBC ResultSet, including executeQuery("select * from people"); getBigDecimal(3); // etc. }. JDBC returns results in a ResultSet object, so we need to declare an instance of the executeQuery(query); while (()) { String s = rs. getBigDecimal.
    A positive number indicates the row number counting from the start of the result set, while a negative number indicates the counting from the end of the result set. The value returned depends on whether or not the result set can detect updates.

    A default ResultSet object is not updatable and has a cursor that moves forward only. The initial value is determined by the Statement object that produced this ResultSet object.

    There's no point mocking objects for a test to directly invoke methods on those mocks from a test unless you're developing a Mocking API. The column age will have index 2, and the column coefficient will have index 3. Your test doesn't call EasyMock.

    For maximum portability, result set columns within each row should be read in left-to-right order, and each column should be read only once. Calling absolute -1 is the same as calling last.

    Parameters Name Type Description columnIndex Integer The index of the column to update the first column is 1, the second is 2, and so on.

    Object — The value of the designated column in the current row of this result set.

    Only one expectation of getBigDecimal will ever be used as specified by: (Decimal("")).andReturn((BigDecimal). A ResultSet is a Java object that contains the results of executing an SQL query. executeQuery("SELECT a, b, c FROM Table1"); while (()) { // retrieve return objects in the Java programming language (getString, getBigDecimal.

    For documentation of this method, see Set#getBigDecimal(int).

    Updates the underlying database with the new contents of the current row of this ResultSet object. ResultSet getTime String, Calendar. Id you do not call this method, the values updated in the ResultSet are never sent to the database. You cannot obtain the number of rows in a ResultSet except if you iterate all the way through it and count the rows.

    1. String, int, long, double, BigDecimal etc. For example, calling the method absolute -1 positions the cursor on the last row; calling the method absolute -2 moves the cursor to the next-to-last row, and so on.

    2. The constant indicating the type for a ResultSet object that is scrollable but generally not sensitive to changes to the data that underlies the ResultSet.
