How to merge multiple result sets from Oracle into one …

To merge multiple result sets into one row, you can use the concatenation operator (||) in Oracle along with subqueries.

Assume there are two result sets, named result1 and result2, which can be merged into one row using the following method:

Combine the columns from result1 and result2 into a new table, showing only the first row.

In this example, data from result1 and result2 are first extracted using a subquery. The corresponding columns are then merged into one column using the concatenation operator (||). Finally, a WHERE clause is used to restrict the return to just one row.

It is necessary to adjust queries and column names according to the actual situation to meet one’s own needs.
