The end out we illustrate by using the following screenshot as follows. In the above example, we use a select statement with the current_timestamp function, here the demo is a database name, and the company is a table name that is created by the user. SELECT CURRENT_TIMESTAMP output FROM pany Now use the CURRENT TIMESTAMP function () as follows. In the above example, we use to insert into statement. Insert into company (Comp_Id, comp_name,comp_address) values(1, "HP", "mumbai"), (2, "Dell", "Pune") In the above example, we use a create table statement to create a new table name as a company with different attributes such as Comp_id, comp_name, and comp_address with different data types and different sizes as shown in the above statement.įor confirmation, insert some records by using the following insert into the statement as follows. Now create a new table by using the create table statement as follows.Ĭreate table company (Comp_Id int(20), comp_name varchar(30), In the above example, we use a create database statement to create a new database name as a demo. Now let’s see the different examples of the current time to understand better as follows:įirst, we need to create a database and table by using the following statement as follows. To keep away from confusion of the time region for this situation, CURRENT TIMESTAMP WITH TIME ZONE ought to be utilized. On the off chance that the CURRENT TIMESTAMP extraordinary register is referred to in timestamp with time region setting (for instance, when contrasted and a timestamp with time region segment), the understood time region for the CURRENT TIMESTAMP exceptional register will be founded on the implied time region framework boundary, which could be an alternate worth from the CURRENT TIME ZONE uncommon register. The time region is resolved from the CURRENT TIME ZONE unique register. On the off chance that you need a timestamp with a time region, the uncommon register can be referred to as CURRENT TIMESTAMP (number) WITH TIME ZONE, or CURRENT TIMESTAMP WITH TIME ZONE? SYSTIMESTAMP can be indicated as an option in contrast to CURRENT TIMESTAMP (12) WITH TIME ZONE. SYSDATE can likewise be determined as an equivalent word for CURRENT TIMESTAMP (0). On the off chance that you need a timestamp with a predetermined accuracy, the extraordinary register can be referred to as CURRENT TIMESTAMP(integer), where the whole number can go 0 – 12. Indicating CURRENT_TIMESTAMP is identical to determining CURRENT TIMESTAMP. The estimation of CURRENT TIMESTAMP in a client characterized work or put away strategy is acquired by using the standards. On the off chance that this unique register is utilized more than one time inside a solitary SQL statement or utilized with CURRENT DATE or CURRENT TIME inside a solitary proclamation, all qualities depend on a solitary clock reading. The CURRENT TIMESTAMP exceptional register determines a timestamp that depends on reading the hour-of-day clock when the SQL statement will be executed on the current server. Microsecond: It is used to return the current microsecond. Second: It is used to return the current second. Minute: It is used to return the current minute. Month: It is used to return the current month.ĭay: It is used to return to the current day. Year: It is used to return the current year. Now let’s see how the current timestamp works in DB 2 as follows.īasically, we can use different parameters for the current timestamp as follows: How current timestamp function work in DB2? AM or PM can be in uppercase or lowercase and must be preceded by a single blank.System table or specified table: System table means system generated table, and specified table means user-generated table.The minute part can be omitted, for example, 1:00 PM is equivalent to 1 PM.If time literals use the USA format, they also conform to the following rules: If the USA format is not used and both minute and second are all zeros, the time literal can be the only hour such as 13 instead of 13:00:00.The second part of a time literal can be omitted. The leading zeros of the hour parts can be skipped, for example, 01:00:00 is the same as 1:00:00.Time literals cannot have leading blanks but can have trailing blanks.Time literals must conform to the following rules: Japanese industrial standard Christian era The first, second, and third bytes represent the hour, minute, and second respectively.ĭb2 stores time values in a special internal format and converts the time values to one of the following formats for the output: Format name Each byte consists of two packed decimal digits. Internally, DB2 uses three bytes to store a time value. Code language: SQL (Structured Query Language) ( sql )
