Hi,
I’m trying to call the array_to_string function like this :
SELECT array_to_string(array[1, 2, 3], '~^~') à it comes directly from the doc.
I get this error msg :
ERROR: parser: parse error at or near "[" at character 24
So I tried this way
SELECT array_to_string('{1, 2, 3}', '~^~')
I get this error msg :
ERROR: Function array_to_string("unknown", "unknown") does not exist
Unable to identify a function that satisfies the given argument types
You may need to add explicit typecasts
So I tried to cast it
SELECT array_to_string(CAST('{1, 2, 3}' AS _int8), CAST('~^~' AS text))
I get this error msg :
ERROR: Function array_to_string(bigint[], text) does not exist
Unable to identify a function that satisfies the given argument types
You may need to add explicit typecasts
Any help would be greatly appreciated…
Thanks
