I was told to use typedef and enum wherever possible, so I made a typedef state to signal whether a cell is DEAD or ALIVE . I made a 3d array that holds all the boards in all generations. when I try to use the array as a parameter of a function, it says error: array type has incomplete element type . Did I do the typedef wrong? Can you not have arrays of user defined types? Here's my code: #include <stdio.h> #include <stdlib.h> typedef enum { DEAD, ALIVE } state; void nextGeneration(state[][][], int, int, int)

What this solution does is, it creates a new function, which takes as it's this value as the function

DECLARE m varchar[]; arr varchar[][] := array[['key1','val1'],['key2','val2']]; BEGIN for m in select arr LOOP raise NOTICE '%',m; END LOOP; END; But the above code returns {{key1,val1},{key2,val2}} in one line. I want to be able to loop over and call another function which takes parameters like: another_func(key1,val1) 回答1: Since PostgreSQL 9.1 there is the convenient FOREACH : DO $do$ DECLARE m varchar[]; arr varchar[] := array[['key1',

I'm doing a barycentric style one to avoid using an explicit for-loop as opposed to a Newton's divided difference style one. The problem I have is that I need to catch a division by zero, but Python (or maybe numpy) just makes it a warning instead of a normal exception. So, what I need to know how to do is to catch this warning as if it were an exception. The related questions to this I found on this site were answered not in the way I needed. Here's my code: import

One of the columns is of the array data type (mycolumn integer[]) . What the heck to I use in my mapper class? I thought resultSet.getArray("mycolumn") would be the right thing to do, but I'm not sure how to get the data out of the java.sql.Array object that gets returned. Any hints or good links on how to do this? 回答1: Array array = resultSet.getArray("mycolumn"); return nonNull(array) ? (Integer[])array.getArray() : null ; 文章来源: Use JDBI to get Postgres

Currently, I am converting the array of bytes into a string in order to store in a Local< String> variable, but this approach is inefficient to my application. Thanks in advance. UPDATED (thanks to Vyacheslav Egorov) I test the solution with an external array but I can't use it on my node.js server code. I have the
