The following excerpt from the listing for running the script inCh04NoBit1Nulls.sql shows the rows that succeeded in entering table T. Notice that there are just two rows, although there are four INSERT statements (see the INSERT statements from the preceding sample). Each row of output includes a known value (0 or 1) for a bit data type in the bit1 column. The two omitted rows correspond to INSERT statements that did not specify a value for the bit1 column. This result confirms the impact of the NOT NULL constraint for the bit1 column in the preceding CREATE TABLE listing. int1 ----------1 NULL bit1 ----0 1 varchar1 -------NULL NULL dec1 ---NULL 9.75 cmp1 ---1 NULL

FREETEXT is similar to CONTAINS except that it returns rows that do not exactly match. It will return rows that have terms with similar meanings to your search terms by using a thesaurus. FREETEXT is less precise than CONTAINS, and it is less flexible. The keywords AND, OR, and NEAR cannot be used with CONTAINS. Avoid using double quotes that specify an exact phrase with FREETEXT, because then SQL Server won t use the thesaurus and will search only for the exact phrase. The same rules about multiple columns apply. Type in and execute the code in Listing 2-22, which compares FREETEXT to LIKE. Listing 2-22. Using FREETEXT USE AdventureWorks2008 GO --1 SELECT FileName, DocumentSummary FROM Production.Document WHERE FREETEXT((DocumentSummary),'provides'); --2 SELECT FileName, DocumentSummary FROM Production.Document WHERE DocumentSummary LIKE '%provides%' Figure 2-18 displays the results from Listing 2-22. The DocumentSummary value in the rows returned from query 1 do not contain the word provides. Query 1 returns the rows anyway because FREETEXT will find similar words as well as exact matches.

You can use the DEFAULT keyword in a column declaration to designate a default value for the column. If an INSERT statement or an UPDATE statement fails to specify a value for the column, then SSE assigns the DEFAULT value, instead of a null value, to the column in a new row. Using a DEFAULT column property assignment makes sense when a null value has no meaning for a column, such as a column to designate whether a contract is signed and available for review. You can represent this type of column with a bit data type that is either 0 for not signed or not available, but 1 for signed and available. A null value makes no sense for this type of column (unless you assume it is possible to not know if a contract is signed and available for review). A DEFAULT constraint can specify A constant, such as a constant value equal to a number or a sequence of characters A function s return value, such as the GETDATE() function to return the current date and time A SQL-92 niladic function, which can supply either the current user s name or the current date and time NULL, which is not necessary because data column values are null by default You specify a column s default value by following the DEFAULT keyword in the column s declaration with a constant, built-in function, a niladic function, or another keyword (NULL). The SQL-92 niladic CURRENT_TIMESTAMP function and the built-in GETDATE() function both return the current date and time. Four different SQL-92 niladic functions return the user account name for the current user: CURRENT_USER, SESSION_USER, SYSTEM_USER, and USER.

Fill() and then display the value of the connection s State property. It will be Open. Comment out the Open() call, and run it again. State will be closed.

You can also specify default values independently of column declarations and bind the default values to columns in one or more tables. This capability will be removed from future versions of SQL Server, including its SSE edition. Therefore, you should use the DEFAULT constraint whenever possible.

Full-Text Search operations can get much more complicated than the information provided here. This was meant to be an overview of the basic syntax. Be sure to see the book Pro Full-Text Search in SQL Server 2008 by Hillary Cotter and Michael Coles (Apress, 2008) to learn more about Full-Text Search. Practice what you have just learned about Full-Text Search by completing Exercise 2-6.
