sql - Batch / Bulk insert in R -


i trying batch insert in r using rjdbc. seems inserts 1 row @ time takes lot of time.

i wondering if knows of solution in r bulk insert data r sql. know rodbc can parametrized insert fast not fast bulk insert.

i don't know "r" language, there bulk sql statement available in sqlexe.

sqlexe utility connects sql databases via odbc , execute valid sql, plus has additional features ( http://sourceforge.net/projects/sqlexe/ )

for example, assuming target table is:

 table: [mydata]  -------------------  row_id      char(1)  row_idx     integer  row_desc    char(32) 

to insert task sqlexe prepare file input:

  input.dat      a,1,this row 1     b,2,this row 2     c,3,this row 3     d,4,this row 4 

the command line import:

  sql --dsn mydb -e "bulk insert input.dat, insert mydata(row_id,row_idx,row_desc) values(?,?,?)"
