To concatenate two strings from two queries in Oracle, you can use the concatenation operator (||). Here is an example: SELECT query1.column1 || query2.column2 AS concatenated_string FROM query1, query2 WHERE query1.id = query2.id; This will concatenate the values of column1 from query1 and column2 from query2 into a single string and display it as concatenated_string in the result set.
