Webmaster 1, IP not as long as fine, 3W garbage IP look cool, waste server resources, bandwidth, consumption is their own money. 3000IP high-quality Visitors, point ads, sponsorship, sales and so on can bring you an unexpected harvest. I used to value traffic, from 2W up to 3W, because the server problem, and then fall back to 2W, but look at their input users, no less than more, that gratified ah, finally

: First, copy the current Access database to a specific directory (used to recover the database in case of an exception).2: Set the number of SQL statements per commit (typically 2W), that is, every 2W SQL statement commits once (prevents the file share lock overflow).3: If an exception occurs during the execution of the SQL statement, overwrite the original database with the backed up database.Note: In thi

the binary sequence.②, sign bit extensionTo convert a complement number to a larger data type, we need to add the sign bit at the beginning.We can conclude from the above two articles: if our primitive bits are [xw-1, xw-2, ..., x2, x1, x0], then the extension can be expressed as: [Xw-1, Xw-1,..., xw-1, xw-2, ..., x2, x1, x0].That is, we want to prove that:　　On the left side of the expression, we added a xw-1 copy of K-bit. If we prove that the sign bit expands one bit, that is k=1, the value r

Why index?Indexes are used to quickly find a row with a specific value in a column, and without using an index, MySQL must start reading the entire table from the first record until it finds the related rows, the larger the table, the more time it takes to query the data, and if the columns in the table have an index. MySQL can quickly reach a location to search for data files without having to look at all the da
