Useful when joining small subsets of data and there is a unique index or highly selective indexed access to the second table (inner) in the join. Efficient for joining large sets of data. A hash table is built in memory on the join key of the smaller table or result set. The larger table is scanned and uses the hash table to retrieve rows. Joins rows from two independent tables or result sets. Sort merge joins are efficient when rows are already sorted. Hash joins are usually more efficient than sort merge joins. Used when no join condition is present. Returns from one table rows that don t satisfy the join condition.

The execution plan (sometimes referred to as the explain plan) is a handy tool used by DBAs and developers for improving the performance of SQL queries. If you re new to using execution plans, follow these heuristics to get started:

C# tutorial: Add annotations to an existing PDF
To add the text annotation to the PDF document, you need to create an instance of PdfReader class to read pages from the PDF source file. Then create an instance of the PdfStamper class. Then use the AddAnnotation method of the PdfStamper class. This method has two arguments: the PdfAnnotation object and page number.

The last observed problem after Day 1 was that some implementations were incorrect or at least allowed misuse of the API. For example, the day1/stackbasedsolution sources follow: /** * Create a circuit to evaluate x1 and x2 and then * verify that its result is false for input (false, true) and * it is true for input (true, true). */ public void testX1andX2() { Stack<Character> s = new Stack<Character> (); s.addAll(Arrays.asList('1', '1')); assertEquals("'1' for '11' input.", '1', CircuitFactory.getBasicCircuit(Operation.AND).evaluate(s)); s.addAll(Arrays.asList('1', '0')); assertEquals("'0' for '10' input.", '0', CircuitFactory.getBasicCircuit(Operation.AND).evaluate(s)); } /** * Create a circuit to evaluate (x1 and x2) or x3 and then * verify that its result is false for input (false, true, false) and * it is true for input (false, false, true). */ public void testX1andX2orX3() { Stack<Character> s = new Stack<Character> (); s.addAll(Arrays.asList('0', '1', '0')); assertEquals("'0' for '010' input.", '0', CircuitFactory.join(CircuitFactory.getTrivialCircuit(), CircuitFactory.getBasicCircuit(Operation.OR), Operation.AND).evaluate(s) ); s.addAll(Arrays.asList('0', '0', '1')); assertEquals("'1' for '001' input.", '1', CircuitFactory.join(CircuitFactory.getTrivialCircuit(), CircuitFactory.getBasicCircuit(Operation.OR), Operation.AND).evaluate(s) ); } /**

Finally, the option to install the library assembly into the GAC is more involved because the hello.dll library needs to be signed in order for it to be installed. This is a matter I ll cover a little later in the Adding Assemblies to the Cache section of this chapter.

Establish how fast the query needs to run. Ensure that accurate statistics have been generated (see recipe 19-13 for details). Determine if indexes exist for columns used in the WHERE clause (see recipe 10-5 for viewing indexes created on a table). Focus on the most costly steps in the execution plan and determine if an index on a column involved in the operation might reduce the cost (see recipe 18-7 for details on creating indexes). When querying large tables, determine if a parallel hint might help. Determine if the query (or parts of it) can be rewritten for better performance.
