What do you see when you do
I’ve imported a csv export of an MS SQL Server log file into a staging table on my local install of Postgresql (9.3/UTF8 encoding) for analysis.
The staging table definition is:
CREATE TABLE sql_log_import
(
id serial NOT NULL,
ts text, -- will convert to ts when merging into sql_server_logs
source character varying(30),
severity character varying(20),
message text,
CONSTRAINT sql_log_import_pk PRIMARY KEY (id)
)
WITH (
OIDS=FALSE
);
ALTER TABLE sql_log_import
OWNER TO postgres;
COMMENT ON COLUMN sql_log_import.ts IS 'will convert to ts when merging into sql_server_logs';
Here’s a copy of the first few lines of the data imported to table sql_log_import:
08/06/2014 03:08:58,spid4s,Unknown,SQL Trace was stopped due to server shutdown. Trace ID = '1'. This is an informational message only; no user action is required.
08/06/2014 03:08:58,spid12s,Unknown,The current event was not reported to the Windows Events log. Operating system error = 1717(The interface is unknown.). You may need to clear the Windows Events log if it is full.
08/06/2014 03:08:58,spid12s,Unknown,Error: 17054<c/> Severity: 16<c/> State: 1.
08/06/2014 03:08:58,Server,Unknown,The connection has been lost with Microsoft Distributed Transaction Coordinator (MS DTC). Recovery of any in-doubt distributed transactions involving Microsoft Distributed Transaction Coordinator (MS DTC) will begin once the connection is re-established. This is an informational message only. No user action is required.
08/06/2014 03:08:58,spid12s,Unknown,Service Broker manager has shut down.
08/06/2014 03:08:55,Server,Unknown,SQL Server is terminating because of a system shutdown. This is an informational message only. No user action is required.
The final table is very similar, but with a timestamp with timezone field for the logged server data. But, when I try to populate the target table with data from the staging table, I keep getting an error. The issue is associated with the to_timestamp function.
Here’s what I’m seeing: If I use to_timestamp with the text data (copied from table sql_log_import.ts), the select statement returns a timestamp with timezone, as expected:
-- Executing query:
select to_timestamp('08/06/2014 03:08:58', 'MM/DD/YYYY hh24:mi:ss')::timestamp with time zone as tstamp
Total query runtime: 78 ms.
1 row retrieved.
But, when I select data from the table sql_log_import, I get an error:
-- Executing query:
select to_timestamp(ts, 'MM/DD/YYYY hh24:mi:ss')::timestamp with time zone as tStamp
from sql_log_import
where id <= 10
********** Error **********
SQL state: 22007
Detail: Value must be an integer.
Any Ideas?
Thanks
