> isin causing SQL syntax error with JDBC
> ---------------------------------------
>
> Key: SPARK-18436
> URL: https://issues.apache.org/jira/browse/SPARK-18436
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 2.0.1
> Environment: Linux, SQL Server 2012
> Reporter: Dan
> Labels: jdbc, sql
>
> When using a JDBC data source, the "isin" function generates invalid SQL
> syntax when called with an empty array, which causes the JDBC driver to throw
> an exception.
> If the array is not empty, it works fine.
> In the below example you can assume that SOURCE_CONNECTION, SQL_DRIVER and
> TABLE are all correctly defined.
> {noformat}
> scala> val filter = Array[String]()
> filter: Array[String] = Array()
> scala> val sortDF = spark.read.format("jdbc").options(Map("url" ->
> SOURCE_CONNECTION, "driver" -> SQL_DRIVER, "dbtable" ->
> TABLE)).load().filter($"cl_ult".isin(filter:_*))
> sortDF: org.apache.spark.sql.Dataset[org.apache.spark.sql.Row] =
> [ibi_bulk_id: bigint, ibi_row_id: int ... 174 more fields]
> scala> sortDF.show()
