mysql - How to use paste function and quotes, in a for loop and insert statement -

-

through for loop r language, i'm trying use insert statement save rows in table: 1 row example looks :

numpat   name       firstnam     birthdate     sex    datprel      adicap1   idpat   numerorum   1       eloste      james      2003-09-27      1    2008-03-24    bhote4p1   468        2

what i've tried write is:

 info<- paste("insert tab_anapath_std1 values (",matop[i,1],", \",matop[i,2],\",\",matop[i,3], \",",matop[i,4],",",matop[i,5],",",matop[i,6],",\",matop[i,7],\",",matop[i,8],",",matop[i,9],")")  sql_update_tbl_ds <- fn$dbsendquery(dbconn, info)

and output got : 

 numpat   name       firstnam       birthdate     sex    datprel      adicap1      idpat     numerorum    1    ,matop[i,2],    ,matop[i,3],    0000-00-00    1    0000-00-00   ,matop[i,7],    468       2

i have real problem manage quotes ; i've tried change without success; how may write please ?

if using fn$ there no need use paste. fn$ alternative paste. write out string , wherever want insert r code surround r code backticks. here self contained example of using fn$ making use of built in bod data frame. 

library(sqldf) matop <- matrix(1:4, 1, 4) <- 1  sql <- "select * bod time = `matop[i, 4]`"  fn$identity(sql) ## [1] "select * bod time = 4"  fn$sqldf(sql) ##   time demand ## 1    4     16

i need hash algorithm produces 64-bit hash code ( long ) fewer collisions string.gethashcode() , fast (no expensive calls cryptographic functions). here's implementation of fnv still shows 3% of collisions after testing 2 million random strings. need number way lower. void main() { const string chars = "abcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyz!#@$%^&*()_+}{\":?><,./;'[]0123456789\\"; const int n = 2000000; var random = new random(); var hashes = new hashset<long>(); int collisions = 0; for(int = 0; < n; i++) { var len = random.next(chars.length); var str = new char[len]; (int j = 0; j < len; j++) { str[j] = chars[random.next(chars.length)]; } var s = new string(str); if(!hashes.add(get64bithash( s ))) collisions++; } console.writeline("collision percentage after " + n + " random strings: " + ((doubl
