[jira] [Created] (FLINK-3086) ExpressionParser does not support
concatenation of suffix operations
Timo Walther created FLINK-3086:
-----------------------------------
Summary: ExpressionParser does not support concatenation of suffix operations
Key: FLINK-3086
URL: https://issues.apache.org/jira/browse/FLINK-3086
Project: Flink
Issue Type: Bug
Components: Table API
Reporter: Timo Walther
The ExpressionParser of the Table API does not support concatenation of suffix operations. e.g. {code}table.select("field.cast(STRING).substring(2)"){code} throws an exception.
{code}
org.apache.flink.api.table.ExpressionException: Could not parse expression: string matching regex `\z' expected but `.' found
at org.apache.flink.api.table.parser.ExpressionParser$.parseExpressionList(ExpressionParser.scala:224)
{code}
However, the Scala implicit Table Expression API supports this.
