PHP timestamp function Gets the UNIX

A table was built today with a column that is the timestamp type, and I meant that when the data is updated, the time of this field will be updated automatically. Cruised does not know much about this type of value, causing an error. This field is found to have a value only when the data is set up, but it is not changed in the update.Find the information, found that I built the statement of the table has a problem:Here is the code snippet:CREATE TABLE

before MySQL 5.6.6, the default behavior of timestamp is: The timestamp column defaults to not nullif the NULL property is not explicitly declared. (While other data types, null values are allowed if no display is declared as NOT null.) Sets the timestamp column value to null, which is automatically stored as the current

The most recent project requires an incremental extraction of the data from the millions, so we have a look at the application of the timestamp and hereby recordTimestamp-timestamp: A unique binary number automatically generated in a database that is independent of time and date and is typically used as a mechanism for adding a version stamp to a table row. Storage size is 8 bytesEach database has a counter

As shown in the preceding example, we will first introduce the timestamp. The timestamp is a set of random numbers generated based on the current system time. Timestamp is generally used as a basis for determining data uniqueness. Next we will introduce how we can use timestamps. We will surely encounter this situation: Bank A and Bank B open your account almost

What is a UNIX timestamp ( UNIX Timestamp)? UNIX timestamp, or Unix time or POSIX time, is a time representation, it is defined as the total number of seconds from GMT, January 1, January 01, 1970 to the present. UNIX timestamps are used not only in UNIX and Unix-like systems, but also in many other operating systems. Currently, a considerable number of operating

1. TIMESTAMP variants TIMESTAMP timestamps can have multiple different features during creation, such: 1. Refresh the data column when creating a new record or modifying an existing record: TIMESTAMP DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP 2. Set this field to the current time when creating a new record, but do not refresh it later:

The PHP timestamp uses the instance code. We will surely encounter this situation: Bank A and Bank B open your account almost simultaneously and see the original 1000 yuan deposit in your account, then both banks want to add 5 to your account. we will certainly encounter this situation: bank A and Bank B open your account almost simultaneously and see the original 1000 yuan deposit in your account. then both banks want to add 500 yuan in deposits to y

The former range is 1000-01-01 00:00:00 ~ 9999-12-31 23:59:59, the

ForWe will surely encounter this situation: Bank A and Bank B open your account almost simultaneously and see the original 1000 yuan deposit in your account, then both banks want to add a deposit of 500 yuan to your account. Then, Bank A will change 1000 yuan to 1500 Yuan, and Bank B will also change 1000 yuan to 1500 yuan. This is terrible! In the end, your bank account has only 1500 Yuan instead of 2000 yuan, which is equivalent to a loss of 500 yuan! This is a serious problem caused by modifi
