thanks Niels! so you are saying this command should work, correct? it currently does not..

"SELECT str_to_date( '1/1/2014' , '%m/%d/%Y' ) as date"

if i am on windows, do i need to install strptime separately? i am currently hitting this error that (from the version tracker) seems like it should've been resolved?

Error in .local(conn, statement, ...) : Unable to execute statement 'SELECT str_to_date( '1/1/2014' , '%m/%d/%Y' ) as date'. Server says '!strptime support missing'.

We have the following date/string conversion functions

create function str_to_date(s string, format string) returns date external name mtime."str_to_date";

    create function date_to_str(d date, format string) returns
    string
            external name mtime."date_to_str";

            create function "convert"(s string, format string)
            returns date
                    external name mtime."str_to_date";

Its based on the unix strftime/strptime (so for the format look at those).

Niels

...

and also

"12/31/2014"

since there are no leading zeroes, the months and days are in different positions so i cannot use something like this to CAST it into a date type.

CAST( SUBSTRING( x , 7 , 10 ) || '-' || SUBSTRING( x , 1 , 2 ) || '-' | | SUBSTRING( x , 4 , 5 ) AS DATE ) AS y

could someone offer advice to convert this string field to date in monetdb? thanks!!

hi richard, a proper strptime call would not be sensitive to field width, the problem is the windows version of monetdb does not have strptime. :/ is there a [find] equivalent in monetdb? otherwise i'm not sure how this could be translated into something that solves my problem? thanks

In a future version we will include a strptime for windows as I found lots of open source (freebsd for example) usable versions. So it should became available in the development branch soon. For now this will not help you unfortunately.

No chance, sorry. It'll take a bit longer than that to find a good and usable (both code-wise and license-wise) implementation and integrate that into our code. And anyway, such a change would only be allowed in a feature release.

Anthony -

The way we sometimes have to implement this stuff in Tableau's compilation layer is to use string search, substring extraction, casting and date arithmetic. It's not pretty, but it works. So something like

[dd] := int( left( [string], find( [string], '/') ) ) [mm] := int( mid( [string], find( [string], '/'), find(

[string], '

...

/', 1 + find([string], '/') ) ) ) [yyyy] := int( mid( [string], find( [string], '/', 1 + find ([string], '/') ) ) ) [date] := dateadd( 'day', [dd]-1, dateadd('month', [mm]-1,

dateadd(

...

'year', [yyyy]-1900, #1900-01-01# ) ) )

I know this isn't MonetDB syntax, but hopefully it gives you the idea. And converting things to simple scalars as quickly as possible tends to be faster, especially when you have datetime

data

...

that does not compress nicely.

I am surprised that the strptime format is sensitive to field width. I'm pretty sure the MySQL implementation is not...

Niels & co. -

Converting strings to date scalars is one of the most common sources of nasty string calculations we see on Tableau Public. It is so bad that about 18 months ago we added a strptime-like function to the language to help our users solve annoying ETL problems like Anthony's. Data from Public also suggests that there are an endless number of date formats in the world (I've extracted nearly 600 so far) so I think it would be really useful if MonetDB could include cross-platform support for a date parsing language like strptime or ICU's time parsing (which is what we embedded in the Tableau Data Engine.) I know MonetDB is not an ETL tool, but some stuff is so common that it is worth making everyone's life easier.

do this with a bunch of horrible CASE statements, but i'm hoping for a more idiomatic strategy. thanks!

hi, i have a VARCHAR column with dates like

"1/1/2014"

Anthony

We have the following date/string conversion

functions

...

create function str_to_date(s string, format string)

returns date

...

external name mtime."str_to_date";

create function date_to_str(d date, format

string) returns

...

string external name mtime."date_to_str";

create function "convert"(s string,

format string)

...

returns date external name

mtime."str_to_date";

...

Its based on the unix strftime/strptime (so for the

format

look at those).

Niels

and also

"12/31/2014"

since there are no leading zeroes, the months and

days are in

positions so i cannot use something like this to

date

type.

CAST( SUBSTRING( x , 7 , 10 ) || '-' || SUBSTRING(

x , 1 , 2 ) ||

...

'-' |

...

| SUBSTRING( x , 4 , 5 ) AS DATE ) AS y

could someone offer advice to convert this string

field to date
