Supondo que as colunas do dataframe R sejam exatamente as mesmas colunas e na mesma ordem no Oracle (nem mais nem menos), considere
apply para colar com recolher todos os valores em cada linha:sqls <- sprintf("INSERT INTO MYTABLE VALUES (%s)",
apply(df, 1, function(i) paste(i, collapse=",")))
sqls
# [1] "INSERT INTO MYTABLE VALUES (2,10,9,50,34,37,29)"
# [2] "INSERT INTO MYTABLE VALUES (7,24,33,21,21,20,3)"
# [3] "INSERT INTO MYTABLE VALUES (39,38,2,33,43,33,7)"
# [4] "INSERT INTO MYTABLE VALUES (30,11,33,1,29,26,11)"
# [5] "INSERT INTO MYTABLE VALUES (50,45,13,27,3,35,36)"
# [6] "INSERT INTO MYTABLE VALUES (41,5,39,17,5,22,5)"
# [7] "INSERT INTO MYTABLE VALUES (21,50,39,30,2,11,49)"
# RECOMMENDED APPROACH TO SPECIFY COLUMNS
sqls <- sprintf("INSERT INTO MYTABLE (Col1, Col2, Col3, Col4, Col5, Col6, Col7) VALUES (%s)",
apply(df, 1, function(i) paste(i, collapse=",")))
connHandle <- odbcConnect("DBName", uid="user", pwd="password")
lapply(sqls, function(s) sqlQuery(connHandle, s))
close(connHandle)
E uma abordagem ainda melhor é usar a parametrização com
RODBCext
onde você acabou de passar o dataframe original sem loop:library(RODBCext)
connHandle <- odbcConnect("DBName", uid="user", pwd="password")
query <- "INSERT INTO MYTABLE (Col1, Col2, Col3, Col4, Col5, Col6, Col7) VALUES (?, ?, ?, ?, ?, ?, ?)"
sqlExecute(connHandle, query, df)
odbcClose(connHandle)
