Alessandro Solimando commented on CALCITE-5972: ----------------------------------------------- For now I suggest to keep it open and decide what to do based on the discussion on the ML (resolve it, improve description if confirmed, duplicate if already existing, etc.) > cannot execute a sql like 'insert into A select * from B' > --------------------------------------------------------- > > Key: CALCITE-5972 > URL: https://issues.apache.org/jira/browse/CALCITE-5972 > Project: Calcite > Issue Type: Bug > Affects Versions: 1.35.0 > Reporter: Moccy.T > Priority: Blocker > > I have put the > {code:java} > org.apache.calcite.adapter.csv.CsvScannableTable{code} > and its related classes (Factory, Reader......, etc.) into my test project. > When I tried to execute a sql like > {code:java} > insert into mysql.calcite_test (select * from csv) {code} > an NPE was thrown. where `mysql` is recognised by JdbcSchema#Factory. When I > debugged, I found that the bind method of the dynamically generated Bindable > code called the JdbcTable's getModifiableCollection() method, which returned > null directly. the bind method's subsequent call to collection.size() threw > an NPE. this code is identified by the This code is generated by > EnumerableTableModify.class. > After that, I tried to execute > {code:java} > insert into mysql.calcite(select * from mysql2.calcite2){code} > There are two JdbcSchema#Factory recognised data sources here, but I found > that the code that was eventually generated by > JdbcToEnumerableConverter.class executed > {code:java} > insert into calcite(select * from mysql2.calcite){code} > in `mysql2` without performing the insert in the `mysql` library. > Are these issues intentional with calcite or are they bugs? > > -- This message was sent by Atlassian Jira (v8.20.10#820010)
