[jira] [Commented] (CALCITE-4622) FLOAT was not supported in method
"appendAsJava" of RexLitera.java
[ https://issues.apache.org/jira/browse/CALCITE-4622?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17359007#comment-17359007 ]
TaoJIn commented on CALCITE-4622:
---------------------------------
[~nobigo]
this error only happened when I wrote a const float value with quote, it would cast the string literal to float literal.

In jdbc sql type ,float is the one of [sql types|https://docs.oracle.com/en/java/javase/11/docs/api/java.sql/java/sql/Types.html].I noticed the jdbc driver return a float type which name is FLOAT and enum value is 12
{code:java}
test b 6 FLOAT 12
