The last two values, the entries for the columns , which sends only one command and returns a single update count. )"); String(1, "Amaretto"); Int(2, 49); Float(3, 9.99); Int(4, 0); Int(5, 0); Batch(); String(1, "Hazelnut"); Int(2, 49); Float(3, 9.99); Int(4, 0); Int(5, 0); Batch(); // ...The DBMS executes the commands in the order in which they were added to the list of commands, so it will first add the row of values for Amaretto, then add the row for Hazelnut, then Amaretto decaf, and finally Hazelnut decaf. and so on for each new // type of coffee int [] update Counts = pstmt.execute Batch(); con.commit(); Auto Commit(true); if (1) one of the SQL statements you added to the batch produces a result set (usually a query) or (2) one of the SQL statements in the batch does not execute successfully for some other reason. In both cases, the update counts are in the same order as the commands that produced them.If column names are used, the developer should guarantee that they uniquely refer to the intended columns by using column aliases.A column alias effectively renames the column of a result set.It is essentially a buffer where a new row can be constructed by calling the updater methods prior to inserting the row into the result set. It allocates database resources to process the statement, identifies the result set (the rows that meet the conditions), and positions the cursor variable before the first row in the result set.The record locks are released when the next commit or rollback statement is issued.

A collection is an ordered group of elements, all of the same type.The SELECT FOR UPDATE statement allows you to lock the records in the cursor result set.You are not required to make changes to the records in order to use this statement.The option to use a string as opposed to an integer is designed to be used when column aliases and names are used in the SQL query that generated the result set.
