Ruben Q L commented on CALCITE-4608:
------------------------------------
bq. Wouldn't it be better to just set the SqlTypeName in constructor instead of
setting isExact?
Yes, I guess that could work. [~amrishlal], would you give this idea a try in a
PR?
> Fix NullPointerException in SqlNumericLiteral.isInteger()
> ---------------------------------------------------------
>
> Key: CALCITE-4608
> URL: https://issues.apache.org/jira/browse/CALCITE-4608
> Project: Calcite
> Issue Type: Bug
> Affects Versions: 1.26.0
> Reporter: Amrish Lal
> Assignee: Ruben Q L
> Priority: Major
> Labels: pull-request-available
> Fix For: 1.27.0
>
> Time Spent: 1h 50m
> Remaining Estimate: 0h

> In 1.26, a NullPointerException is thrown in SqlNumericLiteral.isInteger(),
> due to "this.scale" being null. This can be reproduced by compiling SQL
> statement "SELECT * FROM testTable WHERE floatColumn >
> 1.7976931348623157E308".
> A null check was added through CALCITE-4199 to fix the NullPointerException;
> however, the root cause is that scale and precision are not being properly
> set in {{SqlLiteral.createApproxNumeric}} function which is called to handle
> {{APPROX_NUMERIC_LITERAL}} token.
