[ https://issues.apache.org/jira/browse/CALCITE-980?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Julian Hyde updated CALCITE-980:
--------------------------------
Fix Version/s: 1.6.0
> Not (C='a' or C='b') as well as Not (C='a' and C='b') causes NPE
> ----------------------------------------------------------------
>
> Key: CALCITE-980
> URL: https://issues.apache.org/jira/browse/CALCITE-980
> Project: Calcite
> Issue Type: Bug
> Affects Versions: 1.4.0-incubating
> Reporter: liyang
> Assignee: Vladimir Sitnikov
> Fix For: 1.6.0
>
>
> A where clause like Not (C='a' or C='b') causes NPE if C has NULL value.
> The generated code snippet looks like:
> {code}
> /* 65 */ public boolean moveNext() {
> /* 66 */ while (inputEnumerator.moveNext()) {
> /* 67 */ final Object[] current = (Object[]) inputEnumerator.current();
> /* 68 */ final String inp21_ = current[21] == null ? (String) null : current[21].toString();
> /* 69 */ final Boolean v = inp21_ == null ? (Boolean) null : Boolean.valueOf(org.apache.calcite.runtime.SqlFunctions.eq(inp21_, "A"));
> /* 70 */ final Boolean v0 = inp21_ == null ? (Boolean) null : Boolean.valueOf(org.apache.calcite.runtime.SqlFunctions.eq(inp21_, "B"));
> /* 71 */ if (!(v == null ? (v0 == null || !v0 ? (Boolean) null : Boolean.TRUE) : v ? Boolean.TRUE : v0)) {
> /* 72 */ return true;
> /* 73 */ }
> /* 74 */ }
> /* 75 */ return false;
> /* 76 */ }
> {code}
> And NPE is thrown at line #71 if inp21_ is null.
> Stacktrace:
> {code}
> Caused by: java.lang.NullPointerException
