Is this possible? I have seen examples with array literals as VALUES string, but I cant seen to get it to work with an actual array.
testing code
--This gets me a multidimensional array
with arr AS (
SELECT ARRAY(SELECT ARRAY[fileid::text,tagname,array_to_string(tagvalue,E'\b')]
FROM tagdata_all) -- limit 100)
arr1
)
--Then
INSERT INTO tagdatatest2
SELECT arr1::text[] FROM arr --doesnt work only populates one column with original array
There is no simple way to have each element of an array be inserted into a different column nor have each element populate a different row. You should avoid the multi-dimensional array if at all possible.
