Add script and styles in web form head section. select * from T where x is null; This query cannot use the index we just created the row (NULL, NULL) simply is not in the index, hence the use of the index would in fact return the wrong answer Only if at least one of the columns is defined as NOT NULL can the query use an index For example, the following shows Oracle will use an index for an X IS NULL predicate if there is an index with X on the leading edge and at least one other column in the index is NOT NULL: ops$tkyte@ORA10GR1> create table t ( x int, y int NOT NULL ); Table created ops$tkyte@ORA10GR1> create unique index t_idx on t(x,y); Index created ops$tkyte@ORA10GR1> insert into t values ( 1, 1 ); 1 row created ops$tkyte@ORA10GR1> insert into t values ( NULL, 1 ); 1 row created ops$tkyte@ORA10GR1> begin 2 dbms_stats. If you select a cell that contains a subtotal label, and type a new label that doesn t contain the item name, each item subtotal in the field will display that same text in its label. For example, if you change a subtotal label from Plan Total to Budget Subtotal, every item in the field will have Budget Subtotal as its subtotal label. However, if you include the item name in the revised label, each item subtotal will retain its unique identifier. For example, in a field that shows the sales manager s name, you can change the first subtotal label from Smith Total to Subtotal--Smith. The subtotal for all other sales managers will show the person s name, preceded by Subtotal. gather_table_stats(user,'T'); 3 end; 4 / PL/SQL procedure successfully completed When we go to query that table this time, we ll discover this: ops$tkyte@ORA10GR1> set autotrace on ops$tkyte@ORA10GR1> select * from t where x is null; X Y ---------- ---------1 Execution Plan ---------------------------------------------------------0 SELECT STATEMENT Optimizer=ALL_ROWS (Cost=1 Card=1 Bytes=5) 1 0 INDEX (RANGE SCAN) OF 'T_IDX' (INDEX (UNIQUE)) (Cost=1 Card=1 Bytes=5) Previously, I said that you can use to your advantage the fact that totally null entries are not stored in a B*Tree index here is how Say you have a table with a column that takes exactly two values The values are very skewed; say, 90 percent or more of the rows take on one value and 10 percent or less take on the other value You can index this column efficiently to gain quick access to the minority rows. asp.net create qr code QR code MVC html helper - NET 9 Oct 2017 ...
