So, while working my way through \"Scala for the Impatient\" I found myself wondering: Can you use a Scala for loop without a sequence?
If I create the following sequence in Postgres: CREATE SEQUENCE test INCREMENT 1 MINVALUE 1 MAXVALUE 9223372036854775807
I\'m trying to create a sequence owned by multiple tables, to have a unique identifier over more tables. The only workaround i can think about right know is using a nextval(blabla_id_seq) when INSERTi
I\'m trying to find an easy way to loop (iterate) over an array to find all the开发者_StackOverflow missing numbers in a sequence, the array will look a bit like the one below.
This code does not work as I expected. Could you please explain why? (defn make-str [s c] (let [my-str (ref s)]
To query GRANTS granted to a table I can use a query like: SELECT grantee, privilege_type FROM information_schema.role_t开发者_运维技巧able_grants
I need to generate four datetime objects in Python: \"The next instance of 5:30AM EST\" \"The next instance of 8:30AM EST\"
I have a Groovy code like this to find the subsequence : def number = \"248\" as List def number1= num开发者_StackOverflow社区ber.subsequences()
Is possible to have two tables with the same incrementing sequence? I was trying to do a tree with ID, NAME, ParentID and i have to join two tables.
I need to generate unique numbers for entities inserted into a table. Each number consists from entity creation date and serial number: date + sn. Serial numbers must be reset at the beginning of next
