hi
I thought so too, so I created a table with INT and Varchar columns
desc agtest1
Name Null Type
---- ---- -------------
PID NUMBER(38)
DES VARCHAR2(100)
url="jdbc:oracle:thin:@mpimpclu1-scan:1521/DEVAIM"
table = "agtest1"
user = "bal"
password= "bal"
driver="oracle.jdbc.OracleDriver"
df =
sqlContext.read.jdbc(url=url,table=table,properties={"user":user,"password":password,"driver":driver})
Still the issue persists.
