I have a table with several columns which I want to SELECT: SELECT his_name , her_name, other_name FROM foo; Bu, I instead I want to combine the results all into a single column. Concat (concatenate) The Concat function combines two or more input strings into one continuous string and returns the result. The way we did it in BO was, we concatenated each column with a comma first and then concatenated all 4 separate formulas into one concatenation formula. However, to be safe, you can use CAST() function to explicitly convert a string into a TIMESTAMP value as follows:. As a worksheet function, the & operator can be entered as part of a formula in a cell of a worksheet. also if you were using an oracle 10g db, you can use the collect aggregate: select grp, sum. You have a JSON string that represents an array of objects, and you need to deserialize it into objects you can use in your Scala. But how do we join these two name columns together? 0:44. string_to_replace (mandatory): This is the string that will be searched for within whole_string. EMP table as an example, we might want to retrieve a list of employees for each department. To prevent this, you can replace NULL with empty String while concatenating.
