如何将时间戳插入PostgreSQL数据库

Question

I have a problem inserting timestamp to my psql database using Go.

I form my timestamp with this line:

datetime := currentTime.Format("02-01-2006 15:04:05")

My sql query is:

SqlStatement := `
            INSERT INTO readings (date, temp, humi)
            VALUES ($1, $2, $3)`

And then my call to the psql DB is:

_, err = Db.Exec(SqlStatement, datetime, temp, humi)

(As you can see I have some other variables here but they are not causing any problems.)

When I execute my code I get this error:

pq: date/time field value out of range: "21-11-2018 22:19:59"

Which as I understand it means that the format is not correct.

YET when I input exact same query directly to psql console it successfully adds record(line) to the table.

INSERT INTO readings (date, temp, humi)  VALUES ('02-01-2006 15:04:05', 20, 30);

Side note: This code worked ok before I changed column type from character(20) to timestamp, I even tried incorporating CAST in the SQL but I got the same error.

Answer 1

I can see that datetime variable is string type. I don't know why you must convert time.Time to string before exec query.
If define date column in readings table is TIMESTAMP , you can exec query like this
Db.Exec(SqlStatement, currentTime, temp, humi)

Answer 2

Solved it by adding

SET datestyle TO dmy;

Before each

_, err = Db.Exec(SqlStatement, datetime, temp, humi)

So now I have two Db.Exec functions in a row, one is sending "SET datestyle TO dmy" and the other is this one that is sending actual data.

Wierd.
