Db2 json query example12/27/2022 ![]() ![]() ![]() Hence, in order to retrieve the resultant replaced string, our query statement will become as shown below – Hence, our string to replaced is the “database” and the replace string with which we want to replace the “database” string is “space”. In this original source string which will act as the main supplied string to our REPLACE() function, we have to replace all the occurrences of the database to space. Consider one sample string say “Database Management System helps to maintain, store and retrieve the data from the database.”. Let us have a look at how we can implement the REPLACE() function when using it with string literals. In DB2, we mostly use the REPLCAE() function for cleaning up the data. If any of the arguments to the REPLACE() function is passed as NULL then it will return the output value as NULL. Replace string value is optional for the specification which when not specified the REPLACE() function evaluates to the same value as supplied as the main string. It is necessary to specify the main supplied string and string to be replaced. The replace string is the string with which the string to be replaced should be replaced. The string to be replaced is the unwanted string in the original string, in place of which we want to put some other value of the string. In the above syntax, the main supplied string is the original string that is passed to the function that consists of one or more occurrences of the string to replace. REPLACE (main supplied string, string to be replaced, replace string value) The syntax of the replace function is as shown below Hadoop, Data Science, Statistics & others ![]()
