In Oracle, you can use the LISTAGG function to combine multiple row values of a column into one single row.<\/p>\n
Syntax is as follows:
\nLISTAGG(column_name, separator) WITHIN GROUP (ORDER BY column_name)<\/p>\n
column_name represents the name of the column to be merged, while separator represents the delimiter between the merged row values.<\/p>\n
For example, if we have a table named employees with a column named last_name, we can concatenate all the last_name values into one row, separating them by commas, by using the following statement:
\nSELECT LISTAGG(last_name, ‘,’) WITHIN GROUP (ORDER BY last_name) AS merged_last_names
\nFROM employees;<\/p>\n
This will return a row containing all the last_name values concatenated, with a comma as the separator.<\/p>\n","protected":false},"excerpt":{"rendered":"
