At this point we execute the enable-n pwd command, disabling the function of the PWD original internal command. Under this type, the PWD will be found as an external command. We copied the/usr/sbin/ifconfig to/usr/loacl/sbin and named PWD. Performing the PWD will output the function of Ifconfig display IP address. 650) this.width=650;

PS Synthetic war scenes in the ruins of the city. Synthetic blockbusters require a certain combination of skills. First of all, we should be able to conceive the picture, the desired effect is roughly conceived, and then collect the relevant material for synthesis, the difficulty of synthesis is color unification and light and shadow processing. Final effect The material used for synthesizing. 1, a new 1500*870 size of t

more rows in the outer loop. In addition, it can be seen that this type of connection requires an orderly (i.e. indexed) table with internal loops, and that the outer loop table has fewer rows than the inner loop, or the Query Analyzer prefers a hash Join (described later in this article). Nested loops join also shows that as the amount of data grows this way the cost of performance will grow exponentially, so the Query Analyzer tends to do this when the data is measured to a certain extent.

I explain what is not a radiator, that is, when you use the computer to play the game, the computer will speed up, and some computer cooling system is better, you can keep the computer temperature stable in a safe value. And some of the computer's cooling system is poor, you need an external radiator, to strengthen the heat dissipation, otherwise, when the temperature reaches a critical value, out of self-p

most restrictive test can be performed first, the query can proceed faster. If you have a query that tests two columns, there is an index on each column:WHERE coll = "Some value" and col2 = "Some other value"It is also assumed that there are 900 lines that match the tests on the col1, 300 lines that match the tests on col2, and two tests that pass 30 rows. If you first Test C o l 1, you must check 900 rows to find 30 rows that also match the col2 value. Then

and 3 bytes in the above figure, we know that the export file character set is ZHS16GBK. The following script can be used for valid character sets in the query database: Col nls_charset_id for 9999col nls_charset_name for A30col hex_id for A20select nls_charset_id (value) nls_charset_id, Valu E Nls_charset_name,to_char (nls_charset_id (value), ' xxxx ') hex_idfrom v$nls_valid_valueswhere parameter = ' CHARACTERSET ' ORDER by nls_charset_id (value)/ The output sample is as follows: nl

matches 900 rows of data, the test on col2 matches 300 rows of data, while the test at the same time gets only 30 rows of data. Test Col1 will have 900 rows of data, you need to check that they find 30 of them and col2 in the matching records, 870 of which failed. Test col2 will have 300 rows of data, you need to check that they found 30 of them and the values in the col1 matching records, only 270 failed, so need less calculation and disk I/O. As a
