i trying join outputs of 2 or more mysql queries. if query 1 has n columns , query 2 has m columns, output should have n+m columns. example: select * (select 1,2,3) x, (select 4,5) y; the output here : 1 2 3 4 5 now issue second query may produce no results. case results in no output @ all: select * (select * table_0) x, (select * table_1) y; if table_1 returns no matches, combined output returns no rows. still entries of first table returned. while have workaround, involves individual queries each of m columns. not want create temporary tables , join them. a left join should it: select * (select * table_0) x left join (select * table_1) y on 1;

i have c++ project using qt 5.1.1 , opencv 2.4.6. image processing algorithm runs in separate thread. works fine if call opencv function findcontours() program crashes stack overflow message (right in first time function called, not called several times before) "unhandled exception @ 0x56ec9a47 in sara.exe: 0xc00000fd: stack overflow." i found same problem in case matter of changing project visual studio 2010...but in case, project in vs2010. the algoritm runs fine if create separate console project, calls image processing algorithm, same code inside thread in qt project show stack overflow! if remove findcontours() function, woks should. in both projects use same libs , debug dlls (versioned xxx246d.dll), , compiling program debug. i tried make stack larger changing properties -> configuration properties -> linker -> system -> stack reserve size option, program still crashes, different message, saying "unhandled exception @ 0x76e5c41f in sara....

we're running wso2 api manager 1.4 , upgrade latest version 1.6. can go directly 1.6 or have upgrade 1.5 first? i'm concerned regarding db migration, these scripts seem relevant single version increments. https://svn.wso2.org/repos/wso2/carbon/platform/branches/turing/products/apimgt/1.6.0/modules/distribution/resources/ thanks. as said, databases migrations, can execute migration-1.4.0_to_1.5.0 , migration-1.5.0_to_1.6.0 sqls sequentially. it's important note api manager 1.4.0 based carbon 4.1.x , api manager 1.6.0 based on carbon 4.2.0. see release matrix wso2 products . this means underlying clustering, registry , user-mgt have major changes. api manager related configurations has changed. therefore advice follows. backup existing database , api manager 1.4.0 deployment. migrate databases in incremental manner. re-do configurations in api manager 1.6.0 instances. i.e. direct migration 1.4.0 1.6.0. may compare api manager 1.4.0 repository/conf ...

i working on code suppose calculate sequence: a(n+2)=-2(n+1)+3a(n) a(0)=2 a(1)= -1 unfortunately cannot figure out. i'm new @ (about month) , i'm going try best on own, need help. thank whoever decides me. #include <stdio.h> int mysequence(int n) { if (n==0) return 2; if (n==1) return -1; if (n==2) return 8; return (2 * mysequence(n+1) + mysequence(n+2))/3; } int main() { int n; printf("enter n = "); scanf("%d", &n); printf("%d\n",mysequence(n)); return 0; } look @ line return (2 * mysequence(n+1) + mysequence(n+2))/3 , compare know sequence: a(n+2)=-2(n+1)+3a(n) . they have nothing in common. what want return (-2*mysequence(n-1) + 3*mysequence(n-2)) . why, coefficients should clear enough, copied definition. reason call next level of recursion n-1 , n-2 quite simple, observe: a(n+2)=-2(n+1)+3a(n) -> substitute n n-2 -> a(n)=-2(n-1)+3a(n-2) .

i have find 250th line of txt file not have comma using grep command. file has more 250 lines, have find 250th line not. example: imagine had 10 line file , looking 3rd line did not contain comma lines 1 , 2 not have comma lines 3-7 have comma line 8 not contain comma answer file line 8. i used command : grep -vn "," test.txt and looked 250th line, did following command see if line numbers same, , were. grep -n "this text 250th line" test.txt i don't think should case because 250th line of file without comma should not same line 250th line of regular file because regular file has many lines commas in them, line number should less. what wrong here? thank you. unfortunately, posix disagrees: $ man grep # ... -n, --line-number prefix each line of output 1-based line number within input file. (-n specified posix.) # ... what toss awk on: $ grep -v , text.txt | awk '{ if (nr == 250) { print } }'
