[GENERAL] Crosstab function
Hi Friends, Could somebody help me with crosstab function ? I have warehouse table: CREATE TABLE tblwarehouse ( id integer NOT NULL, warehousename character varying(20) ); COPY tblwarehouse (id, warehousename) FROM stdin; 2 OFFICE 3 STORE2 \. And product table : CREATE TABLE tblproduct ( id serial NOT NULL, produkid text, warehouseid integer, onhand integer ); COPY tblproduct (produkid, warehouseid, onhand) FROM stdin; 279140414 2 10 279140421 3 10 279140414 3 45 \. I need crosstab function to display record from tblproduct like this : PRODUKID| OFFICE | STORE2 | TOTAL ---+++ -- 279140414 | 10 | 45 | 55 279140421 | 0 | 10 | 10 The crosstab warehouse column name (OFFICE Store2) is taken from tblwarehouse so when user add warehouse, crosstab column name will change automatically. And also each row has total qty. Thanks in advance !

I was more interested in being able to instrument the Pg internals, connection counts, transaction rates, RAM usage etc. In a similar sort of way to MS-SQL. Running transactions against an individual DB is still useful but I was hoping to do better. As long as you can run arbitrary SQL, you can get all the information out.

If so, I suggest you take a look at the check_postgres nagios plugin or the munin plugins for some examples of which SQL to run to get the interesting metrics back that you want.

Likely the easiest way to get that will be to UNION ALL the main real warehouse query and another query the groups by product and sum-counts that values from the individual warehouses.

Re: [GENERAL] C++, Postgres , libpqxx huge query
Thanks John for your answer. The problem is how do I declare the cursor and fetch through C++ and libpq++? And if I fetch 1000 rows at a time, then how do I handle that when I reach the end and there are less than 1000 rows available? Or I need to fetch one row at a time like this http://stackoverflow.com/questions/16128142/how-to-use-pqxxstateless-cursor-class-from-libpqxx ?

Try looking into either using a serverside cursor or COPY.
Another possibility is libpq's recently-introduced row-at-a-time mode:
http://www.postgresql.org/docs/9.3/static/libpq-single-row-mode.html
though I'm not sure how effectively that's supported by libpqxx.

Hi everybody Thank you for your help! I upgrade the version of 9.0.15 to 9.0.17.

You can run the favorite food query, save the result to a variable, then build a dynamic SQL query and inject the value of the variable in place of where you would place the column name alias. Pick whatever language/client you wish. I do not understand how you get: SELECT id, 'fruit' FROM foods; since the result of a select is a table, not another select...

Re: [GENERAL] Crosstab function
Hi David, Are you sure that there is no pure sql solution for this ? I think (with my very limited postgres knowledge), function can solve this. So far i can use command: select * from crosstab ( 'select produkid, warehouseid, onhand from tblproduct order by 1', 'select distinct warehouseid from tblproduct order by 1' ) as ct (produkid text, office int, store2 int); and I have this result : PRODUKID| OFFICE | STORE2 | ---+++ 279140414 | 10 | 45 | 279140421 || 10 | The problem is the column header is static. If I have new warehouse, I should manually add it in the column header. IF I use command : select 'Produk ID text, ' || array_to_string(array(select warehousename from tblwarehouse), ' int, ') || ' int'; I can get : Produk ID text, OFFICE int, STORE2 int Which is the column header I need but I really have no idea how to use this as column header.

You could build the necessary string in a pl/pgsql language function but you would still have trouble getting the data out of the function the way you want; unless you output a single text column no matter the original data ( basically output a cvs version of the crosstab result). There is no dynamic execution in SQL so even though you can get a string that looks like what you want you cannot do anything with it. Only data is allowed to be dynamic; the engine has to know the names and types of all schema objects before it can start so there is no way a query can retrieve these things from its own data. It's the whole cart-horse thing... The solution is to build the query in the client and send it. Make sure you look at the various quote_ functions in order to minimize the risk of SQL injection attacks. These are especially useful for pl/pgsql functions but you might be able to use them in your first query so that you can avoid coding all the quoting and escaping rules into your application. At minimum double-quote all your identifiers and make sure there are no unescaped embedded double-quotes. If the only variables are from data in tables putting constraints on those tables would probably be useful as well - you limit valid identifiers but minimized risk of bad data causing an issue.
