Hi: 我用Table API创建了一张表，表字段如下： key:FLOAT, col1: FLOAT, col2: FLOAT, col3: FLOAT
使用如下SQL进行查询： select * from flink where (key < 5) or ((key > 10 and key < 12) or (key in (15, 16, 17)) or (key > 18 and key <= 19)) 执行时报了如下错误： Exception in thread "main" java.lang.UnsupportedOperationException: class org.apache.calcite.sql.type.SqlTypeName: FLOAT at org.apache.calcite.util.Util.needToImplement(Util.java:1075) at org.apache.calcite.rex.RexLiteral.appendAsJava(RexLiteral.java:703) at org.apache.calcite.rex.RexLiteral.toJavaString(RexLiteral.java:408) at org.apache.calcite.rex.RexLiteral.computeDigest(RexLiteral.java:276) at org.apache.calcite.rex.RexLiteral.<init>(RexLiteral.java:223) at org.apache.calcite.rex.RexLiteral.toLiteral(RexLiteral.java:737) at org.apache.calcite.rex.RexLiteral.lambda$printSarg$4(RexLiteral.java:710) at org.apache.calcite.util.RangeSets$Printer.lessThan(RangeSets.java:392) at org.apache.calcite.util.RangeSets.forEach(RangeSets.java:253) at org.apache.calcite.util.Sarg.lambda$printTo$0(Sarg.java:110) at org.apache.calcite.linq4j.Ord.forEach(Ord.java:157) at org.apache.calcite.util.Sarg.printTo(Sarg.java:106) at org.apache.calcite.rex.RexLiteral.printSarg(RexLiteral.java:709) at org.apache.calcite.rex.RexLiteral.lambda$appendAsJava$1(RexLiteral.java:652) at org.apache.calcite.util.Util.asStringBuilder(Util.java:2502) at org.apache.calcite.rex.RexLiteral.appendAsJava(RexLiteral.java:651) at org.apache.calcite.rex.RexLiteral.toJavaString(RexLiteral.java:408) at org.apache.calcite.rex.RexLiteral.computeDigest(RexLiteral.java:276) at org.apache.calcite.rex.RexLiteral.<init>(RexLiteral.java:223) at org.apache.calcite.rex.RexBuilder.makeLiteral(RexBuilder.java:971) 麻烦问一下，这是什么原因？定义字段时不能用Float吗？如果不能用，假如我的source或者sink需要是Float类型，怎么处理？望知道的大佬告知，感谢。 祝好！ automths
