Question:
I am trying to select various values from various fields. I want to be able to concatenate the results into a string variable, then insert the string into another table. What function do I use to convert the fields into a string so that I can join them together?
Answer:
You need the concatenation operator: ||, as in:
SELECT field1||field2||field3 from my_table
This performs all necessary conversions and returns a character type.
