In that case function call may be delegated to [suffixFunctionCall => Call methods|https://github.com/NickolayVasilishin/flink/blob/FLINK-4565/flink-libraries/flink-table/src/main/scala/org/apache/flink/api/table/expressions/ExpressionParser.scala#L226]? Can you explain me why, by which criteria some functions are implemented in their own "lazy val functions" (such as [SUM|https://github.com/NickolayVasilishin/flink/blob/FLINK-4565/flink-libraries/flink-table/src/main/scala/org/apache/flink/api/table/expressions/ExpressionParser.scala#L169], [IF|https://github.com/NickolayVasilishin/flink/blob/FLINK-4565/flink-libraries/flink-table/src/main/scala/org/apache/flink/api/table/expressions/ExpressionParser.scala#L207], [AVG|https://github.com/NickolayVasilishin/flink/blob/FLINK-4565/flink-libraries/flink-table/src/main/scala/org/apache/flink/api/table/expressions/ExpressionParser.scala#L181]) and others are called through [suffixFunctionCall => Call methods|https://github.com/NickolayVasilishin/flink/blob/FLINK-4565/flink-libraries/flink-table/src/main/scala/org/apache/flink/api/table/expressions/ExpressionParser.scala#L226]? > Support for SQL IN operator > --------------------------- > > Key: FLINK-4565 > URL: https://issues.apache.org/jira/browse/FLINK-4565 > Project: Flink > Issue Type: Improvement > Components: Table API & SQL > Reporter: Timo Walther > Assignee: Nikolay Vasilishin > > It seems that Flink SQL supports the uncorrelated sub-query IN operator.
