c# - system.outofmemoryexception When filling DataAdapter? -

-

i have pull 150k records db. using da.fill(ds,"query") , throwing system.outofmemoryexception.

dim dagrid new sqldataadapter(sqlcmd_q) dagrid.fill(dsgrid, "query") dagrid.dispose()

i need datatable only. cannot use xml. because need assign mschartcontrol display scotterplot.

any suggestions?

the first thing i'd check how many columns returning, , data types are. although 150k records lot, shouldn't give oom exception unless each record 13k in length (on 32-bit machine). suggests me either returning way more fields need, or perhaps of fields large strings or binary data. try cutting down select statement return fields absolutely needed display.

if doesn't work, may need move datatable list of custom data type (a class appropriate fields).

c# - Is it possible to remove an existing registration from Autofac container builder? -

something along lines: builder.registertype<mytype>().as<itype>(); builder.registertype<mytype2>().as<itype>(); builder.deregistertype<mytype>().as<itype>() var container = builder.build(); var types = container.resolve<ienumerable<itype>>(); assert.istrue(types.count == 1); assert.istrue(types[0].gettype == typeof(mytype2)); scenario: go through bunch of assemblies , go register types want make sure have 1 implementation of given type. need before create container. track on own nice if autofac me bit. this cannot done directly using containerbuilder , unless start on new one. mind you, having first built container should able construct new container filtering away unwanted types , reusing registrations first container. this: ... var container = builder.build(); builder = new containerbuilder(); var components = container.componentregistry.registrations .where(cr => cr.activator.limittype != typ

php - Mysql PK and FK char(36) vs int(10) -

-
i have read mysql can handle indexes , searches better if tables keys integers rather char(36) uuid's. is worth converting int(10)? note: use 1 server , have have plans use multiple databases concurrently therefore removing 1 of big reasons using uuid. our tables innodb if makes difference. thanks in advance. usually rdbms can handle integer keys pk more efficient, other datatypes. reason how build index column, yes: long dont require string (or other typed) keys, should use integers. however: char(36) , int(10) far away being equal, because int(10) much smaller, char(36). dont know, if require many different keys, should keep in mind. update, complete last paragraph: int(10) 32-bit, char(36) 36 - ^byte^ (= 288-bit). not mean, int consumes less space, means, char(36) has 4 times more different keys.
