![]() If both expression1 and expression2 are together specified in arguments and expression2 is not an integer then it is necessary that expression1 must be a valid representation of date value in string or the value of the date in DATE datatype and expression2 should be a valid representation of time value in string format or a value of TIME datatype.If the expression1 is specified and it is in character string format then it must be either a valid representation of timestamp or date in character string format, a 12-length character string which is generated by using the GENERATE_UNIQUE function or a 14 digit wide string of digits which specifies the valid time and date value in yyyyxxddhhmmss format where ss is the seconds, mm are minutes, hh is an hour, dd is the day, xx is month value and yyyy is the value of the year in the timestamp.As expression2 is optional in nature, if it is not specified then the usage of only one argument then it should be any expression that gives the output return value in either DATE, character string provided it is not a CLOB value, or TIMESTAMP built-in datatypes.There are certain rules to be followed while using this function and expression 2 argument that is supplied which are mentioned below – Note that TIMESTAMP is the function available to use with graphic strings to represent the date, time, or timestamp only in Unicode databases because the graphic string provided in the argument is converted into a character string and then used for the execution of the function. Expression1 is a compulsory value while expression2 is optional in nature. The output of the TIMESTAMP function is the value of the TIMESTAMP datatype which varies depending on parameters passed to it. The syntax of the TIMESTAMP function is as shown below – However, we can have different types of formats for timestamps that are supported by DB2 and some of which also allow us to store the timezone-related information in the field. Name of the column TIMESTAMP which mostly stores the value of date and time in yyyy-mm-dd-hh.mm.ss Format. The syntax of TIMESTAMP datatype is as shown below – Hadoop, Data Science, Statistics & others An additional optional temporal parameter for storing and specifying the time zone of that place where the data is being recorded. There is one more thing called fractional seconds which can be stored to maintain an accurate and precise value of time. The TIMESTAMP datatype helps us to store date as well as time and contains a total of seven different parts stored in it which are year, month, and day for storing date and hour, minute, and seconds to store the time. ![]() In this article, we will study the syntax and usage of TIMESTAMP datatype and function in DB2 along with the examples. In order to store these values, we can make use of timestamp data type in DB2. It is required to store the date and time as well as other information such as timestamp for various transactions that are happened in real-time events such as sales time and date in stores for every customer, date and time of multiple flights, buses, and trains facility and many other. DB2 TIMESTAMP is also the datatype available in DB2 Database Management System provided by IBM which helps to store the temporal values in the database. The function is used for retrieving the timestamp value depending on the pair of parameter values that is supplied to it. DB2 TIMESTAMP is also a function provided by IBM as well as the data type used for storing temporal values.
