我一直在尝试连接到我的DB2服务器两天，并且已经在这里尝试了每个帖子并且没有成功。
library(rJava)
library(RJDBC)
library(DBI)
#Enter the values for you database connection
dsn_driver = "com.ibm.db2.jcc.DB2Driver"
dsn_database = "D0042T04"
dsn_hostname = "DB2"
dsn_port = "50000"
dsn_protocol = "TCPIP"
dsn_uid = "db2User"
dsn_pwd = "secret!"
jcc = JDBC("com.ibm.db2.jcc.DB2Driver", "c:/development/R/db2jcc.jar");
path = "jdbc:db2://" + dsn_hostname + ":" + dsn_port + "/" + dsn_database + sep=""
jdbc_path = paste("jdbc:db2://", dsn_hostname, ":", dsn_port, "/", dsn_database, sep="");
conn = dbConnect(jcc, jdbc_path, user=dsn_uid, password=dsn_pwd)
query = "SELECT * FROM core.account FETCH FIRST 10 ROWS ONLY";
rs = dbSendQuery(conn, query);
df = fetch(rs, -1);
df
dbDisconnect(conn)
当我运行脚本时，我得到以下
> query = "SELECT * FROM core.account FETCH FIRST 10 ROWS ONLY;";
> rs = dbSendQuery(conn, query);
Error in dbSendQuery(conn, query) : could not find function "dbSendQuery"
