spring - How to pass BigInteger from java to Postgres? -


i need pass biginteger argument sql query. (on postgres 9.2) have code in dao:

    public list<personinfo> select(string id) {         biginteger bigintid = new biginteger(id);         jdbctemplate select = new jdbctemplate(datasource);         return select             .query("select * pe.supplier_input_data id = ?",                     new object[] { bigintid },                     new personrowmapper());     }

i getting following exception:

{"error":"error invoking getpersoninfobyid.[org.springframework.jdbc.badsqlgrammarexception: preparedstatementcallback;  bad sql grammar [select * pe.supplier_input_data id = ?];  nested exception org.postgresql.util.psqlexception:  can't infer sql type use instance of java.math.biginteger.  use setobject() explicit types value specify type use.]"}

the id of type bigint

tried pass plain string - throws type exception. googled message in exception - no relevant result. ideas?

support biginteger added in jdbc 4.1 (java 7), somehow had missed when wrote answer.

specifically section 3.1 overview of changes of jdbc 4.1 specification states:

  • additional mappings table b-4, mapping java object jdbc types
    [..]
    support added map java.lang.biginteger jdbc bigint.
  • additional mappings table b-5, performed setobject , setnull between java object types , target jdbc types
    [..]
    allow conversion of java.lang.biginteger char, varchar, longvarchar, , bigint.

i'm not sure how supported across drivers.

original answer

the jdbc specification not include support biginteger; either need use different datatype (eg bigdecimal scale 0), or find out if postgresql driver offers implementation specific way set biginteger value.

the documentation of error mentioned in title says if commands out of sync; can't run command now in client code, calling client functions in wrong order. this can happen, example, if using mysql_use_result() , try execute new query before have called mysql_free_result(). can happen if try execute 2 queries return data without calling mysql_use_result() or mysql_store_result() in between. from here: http://dev.mysql.com/doc/refman/5.0/en/commands-out-of-sync.html but in first query not fetching data mysql database, inserting. , in second query getting data database. here code $connection = mysqli_connect("localhost","username","password","tbl_msgs"); if(mysqli_connect_errno($connection)) { die("failed connect mysql: " . mysqli_connect_error()); } $query = "insert users (total_comments, total_views) values ({$total_comments}, {$total_views});"; $query .= "insert msgs (no...

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).

i'm using named queries fetch entities database using jpa , hibernate , came across puzzling me: how come there no default implementations of javax.persistence.parameter interface? i rather impressed how @staticmetamodel used criteriabuilder in jpa2 meaning type safety , don't have mess around setting string names. wanted apply similar of jpa1 ejb's i'm working on: dealergroup_.class: public dealergroup_ { public parameter<integer> id = new parameterimpl<integer>("id"); /// etc... } dealergroupfacade.class: // ... public dealergroup fetch(integer id) { typedquery<dealergroup> query = em.createnamedquery("dealergroup.fetchbyid", dealergroup.class); query.setparameter(dealergroup_.id, query); return query.getsingleresult(); } // ... i surprised find there no implementations of parameter interface - of course, implement myself absence makes me suspicious may mistake using in way? should implementing parameter...
