Hello,
This post might be unreadable in your mail client. If so try to copy it in to notepad as there is a long query statement.
I have following table in the DB.
Server2=# \d ss21_file
Table "srx.ss21_file"
Column | Type | Modifiers
-------------------+------------------------+-----------
value | character varying(30) |
fileindex | bigint |
filename | character varying(80) |
filetime | character varying(100) |
filesizeinrecords | bigint |
filesizeinbytes | bigint |
sourceid | character varying(300) |
Indexes:
"ss21_filetime" UNIQUE, btree (filetime)
When executing following query I get following error:
Server2=# SELECT value, fileIndex, fileName, fileTime, fileSizeInRecords, fileSizeInBytes, sourceID FROM ss21_file WHERE filetime < to_timestamp('2015-05-04 22:13:14.000', 'YYYY/MM/DD-HH24:MI:SS.FF3');
ERROR: operator does not exist: character varying < timestamp with time zone
LINE 1: ...ytes, sourceID FROM ss21_file WHERE filetime < to_times...
^
HINT: No operator matches the given name and argument type(s). You might need to add explicit type casts.
My assumption is that, it is because "filetime" column is "character varying" and in WHERE condition value there is converted to timestamp.
When I execute this same query but instead to_timestamp I use regular string eg. '2015-05-04 22:13:14.000' (NOTE: single quotas) it works quite good.
If this is correct, is there any way to force to_"timestamp" function to be convertrd in to "character varying" or display its value in single quotas ?
Server2=# SELECT value, fileIndex, fileName, fileTime, fileSizeInRecords, fileSizeInBytes, sourceID FROM ss21_file WHERE filetime < '2015-05-04 22:13:14.000';
value | fileindex | filename | filetime | filesizeinrecords | filesizeinbytes | sourceid
