The returned timestamp is a DATETIME value without the time zone offset. Views and expressions that reference this column cannot be indexed. I have a website that does inserts into this table below.
The time zone offset reflects the current local time of the SQL session. If you omit precision, then the default is 6. This function is the ANSI SQL equivalent to the T-SQL GETDATE() function, so you can use whichever one you prefer. YYYYMMDDHHMMSS format if used in a numeric context in versions of MySQL prior to MySQL 4. To obtain just the time, use the function CURRENT _TIME. This function returns the current database system timestamp as a datetime value, without the database time zone offset. Let’s take a look at the following example.
Side note: you should not make your clustered key (a) this wide (nvarchar(64) = 1bytes! If this special register is used more than once within a single SQL statement, or used with CURRENT DATE or CURRENT TIME within a single statement, all values are based on a single clock reading. You can insert the current timestamp by just casting to the correct type: insert into. DBInsert Current TimeStamp.
Default precision is 6. As you can see from the output, MySQL used the timestamp at the time of inserting as a default value for the created_at column. This feature is called automatic initialization. Use timestamp in insert statement : Timestamp SQL Data Types. The Database can also be restored at any time.
Our Try- SQL Editor uses WebSQL to demonstrate SQL. A Database-object is created in your browser, for testing purposes. The optional precision argument is not supported in ESQL. The default precision of CURRENT _TIME is still decimals, so in Firebird 2. Within a PSQL module (procedure, trigger or executable block),.
Do not use the returned value for precise time ordering between. But this one does not work as expected. APPLIES TO: SQL Server Azure SQL Database Azure Synapse Analytics ( SQL DW) Parallel Data Warehouse. Returns a datetime2(7) value that contains the date and time of the computer on which the instance of SQL Server is running.

Both of them derive value from the operating system of the computer on which SQL Server instance is running. Specifying current date and time values. Addition and subtraction are the only arithmetic operators applicable to date, time, and timestamp values. If the current timestamp is being supplied to a field of data type PosixTime, the current timestamp value is returned in POSIXTIME data type format.
Tracking Row Creating or Modification Times. While working with the database of a large application you often need to store record creation time or last modification time in your database, for example, storing the date and time when a user , or when a user last updated his passwor etc. Returns the current database system timestamp as a datetime value.
