Basically I have an ETL with 2 updates and I want to write the same updates in Pyspark table_a: +---+-----------+-------+--------------+ |key|col_a | col_b | current_flag | +---+-----------+-------+--------------+ |001| Value1 | T123 | Y | |002| oth_val1 | T123 | N | |003| oth_val2 | T123 | N | |004| oth_val3 | T123 | N | |005| Value2 | T123 | Y | |006| oth_val4 | T789 | N | |007| Value2 | T789 | Y | |008| Value1 | T789 | N | +---+-----------+-------+--------------+ UPDATE table_abc SET col_a = 'Value1' WHERE col_b IN ( SELECT col_b FROM table_abc WHERE col_a = 'Value1' and current_flag = 'Y' ) AND current_flag = 'N' COMMIT; +---+-----------+-------+--------------+ |key|col_a | col_b | current_flag | +---+-----------+-------+--------------+ |001| Value1 | T123 | Y | |002| Value1 | T123 | N | -- updated |003| Value1 | T123 | N | -- updated |004| Value1 | T123 | N | -- updated |005| Value2 | T123 | Y | |006| oth_val4 | T789 | N | |007| Value2 | T789 | Y | |008| Value1 | T789 | N | +---+-----------+-------+--------------+ UPDATE table_abc SET col_a = 'Value2' WHERE col_b IN ( SELECT col_b FROM table_abc WHERE col_a = 'Value2' and current_flag = 'Y' ) AND current_flag = 'N' COMMIT +---+-----------+-------+--------------+ |key|col_a | col_b | current_flag | +---+-----------+-------+--------------+ |001| Value1 | T123 | Y | |002| Value1 | T123 | N | |003| Value1 | T123 | N | |004| Value1 | T123 | N | |005| Value2 | T123 | Y | |006| Value2 | T789 | N | -- updated |007| Value2 | T789 | Y | |008| Value2 | T789 | N | -- updated +---+-----------+-------+--------------+ --------------------------------------------------------- #pyspark code to reproduce the updates #initial dataframe is "table_a" tval1 = [login to view URL]( col("col_a") == lit("Value1") & col("current_flag") == lit("Y") ) t= [login to view URL]("t1").join( [login to view URL]("tval1"), col("t1.col_b") == col("tval1.col_b"), "left-outer" ).select( col("[login to view URL]"), when( col("tval1.col_b").isNotNull(), lit("Value1") ).otherwise(col("t1.col_a")).alias("col_a"), col("t1.col_b"), col("t1.current_flag") ) #use data frame t from above tval2 = [login to view URL]( col("col_a") == lit("Value2") & col("current_flag") == lit("Y") ) t_new = [login to view URL]("t1").join( [login to view URL]("tval2"), col("t1.col_b") == col("tval2.col_b"), "left-outer" ).select( col("[login to view URL]"), when( col("tval2.col_b").isNotNull(), lit("Value2") ).otherwise(col("t1.col_a")).alias("col_a"), col("t1.col_b"), col("t1.current_flag") ) but what really happens in Pyspark is this: t_new: +---+-----------+-------+--------------+ |key|col_a | col_b | current_flag | +---+-----------+-------+--------------+ |001| Value1 | T123 | Y | |002| Value2 | T123 | N | |003| Value2 | T123 | N | |004| Value2 | T123 | N | |005| Value2 | T123 | Y | |006| Value2 | T789 | N | |007| Value2 | T789 | Y | |008| Value2 | T789 | N | +---+-----------+-------+--------------+

Hi, I've been working as a data engineer for almost two years. I am currently working in the Scala and Spark programming languages but I can work in pySpark as well it is pretty similar. I've seen your issue and understood it, and there are a couple of ways for solving this. P.S I've already found one way to solve the first issue. The second issue is pretty much the same, just with other parameters. Kind regards, Danilo

I am a software engineer working in Big Data technologies like pyspark for the last 1 year and hence I can achieve the results pretty well by using sql equivalents there like the used queries as it is. Connect to discuss further.
