Pyspark: How to pass the argument in the sql scripts while executing through hive context
I am sending the column name in the for loop and want use that variable(which contains column name) in the sql query inside for loop. Could you please help
for line in tcp.collect():
hive_context.sql("SELECT 'zip' as Variable_name,percentile(zip, 0.25) as Q1, percentile(zip, 0.75) as Q3 FROM df_tab").show() -- Zip should be replaced by variable line
I tried to do something like this as well, but it dint work
query="SELECT {d_line} as Variable_name, percentile({line}, 0.25) as Q1, percentile({line}, 0.75) as Q3 FROM df_tab".format(d_line=line) --this gives me output as
SELECT zip as Variable_name,percentile(zip, 0.25) as Q1, percentile(zip, 0.75) as Q3 FROM df_tab --here zip has to come in single quote
Expected Output query: SELECT 'zip' as Variable_name,percentile(zip, 0.25) as Q1, percentile(zip, 0.75) as Q3 FROM df_tab
