Re: Concatenate a string to a Column of type string in DataFrame

In earlier versions you should be able to use callUdf or callUDF (depending on which version) and call the hive function "concat". On Sun, Dec 13, 2015 at 3:05 AM, Yanbo Liang wrote: > Sorry, it was added since 1.5.0. > > 2015-12-13 2:07 GMT+08:00 Satish

Concatenate a string to a Column of type string in DataFrame

HI, I am trying to update a column value in DataFrame, incrementing a column of integer data type than the below code works val new_df=old_df.select(df("Int_Column")+10) If I implement the similar approach for appending a string to a column of string datatype as below than it does not error out

Hi Satish, You can refer the following code snippet: df.select(concat(col("String_Column"), lit("00:00:000"))) Yanbo 2015-12-12 16:01 GMT+08:00 satish chandra j : > HI, > I am trying to update a column value in DataFrame, incrementing a column > of integer data type
