to be able to click on Basin, you need to first switch to desired iframe. Because it is wrapped inside an iframe.

Apache Calcite CSV Adapter - SQL Client

Asked 2022-Feb-23 at 16:32

I am working on the development of a Connector interface with Elasticsearch (translate SQL to API DSL query syntax) .

I am starting with Apache Calcite CSV Adapter as a first step to test Calcite capabilities. I followed the tutorial https://calcite.apache.org/docs/tutorial.html

My question is how to use the JDBC connector (and which configuration) in a SQL client like Dbeaver or Squirrel... ?

Thanks

The DBeaver documentation describes how to add a new database driver. You can specify whatever parameters you need as well as provide a Calcite JAR file so the necessary code is available.

The class name should be org.apache.calcite.jdbc.Driver. The URL Template will be something like jdbc:calcite:model=path/to/model.json where you specify a path to a model.json file which contains the necessary model to create the connection.

How to modify a RelNode tree?

Asked 2022-Feb-19 at 15:51

I am using Apache Calcite to validate and rewrite SQL based on policies that put certain restrictions on these SQL queries. I am trying to modify a RelNode tree in order to rewrite the query to enforce these restrictions. I want to be able to remove certain parts from a query (after it has been validated). For example, I want to be able to remove projection fields (which I managed to do using RelBuilder.projectExcept) and to remove a table scan and its corresponding column references from a query.

Simple example:

A rule transforms (in this case TransformationRule) a RelNode to an equivalent RelNode i.e both should have the same row. Assumming you want to use HepPlanner with your custom rule registered and if the rule matches, it will eventually check whether the original rel and the transformed rel have the same row using RelOptUtil#verifyTypeEquivalence. I think mutating the relNode via RelVisitor or mutating the sqlNode via SqlVisitor is your best bet.

How to use SqlStdOperatorTable.IN with RelBuilder?

Asked 2022-Jan-28 at 13:17

I'm trying to build a rexNode similar to using RelBuilder. But I can't really find any example or any test using SqlStdOperatorTable.IN. Could please somebody share any? Or explain how to use SqlStdOperatorTable.IN. Saw something here, but it didn't help much and didn't work for me( RelBuilder builder = RelBuilder.create(calciteConfig); RelRunner relRunner = calciteConnection.unwrap(RelRunner.class); builder.scan("dremio", "test1"); RexBuilder rexBuilder = new RexBuilder(new SqlTypeFactoryImpl(RelDataTypeSystem.DEFAULT)); RexNode rexNode = rexBuilder.makeCall( SqlStdOperatorTable.IN, builder.field("device_type"), rexBuilder.makeLiteral("TABLET"), rexBuilder.makeLiteral("MOBILE")); RelNode test1 = builder .filter(rexNode) .limit(10, 100) .build();

how to build sql from RelBuild without schema info?

ANSWER

Answered 2021-Dec-23 at 22:05

Only one method in RelBuilder uses a RelOptSchema: scan(String...) (and its variant Scan(Iterable)). Which makes sense when you consider that the purpose of RelOptSchema is as a directory service, converting a table name (or table path, consisting of a table name qualified with catalog and/or schema names) into a RelOptTable object.

If you have 'free-standing' table objects that are not accessed via a namespace then you can create TableScan relational expressions directly and then call RelBuilder.push(RelNode) to add them to the stack. Since you never call RelBuilder.scan you can create RelBuilder with a null RelOptSchema.

But in your case, it looks as if you don't have free-standing table objects. That's a problem for Calcite, because it needs to know that your "EMP" table has a field called "DEPTNO" and it has type INTEGER.

So I suggest that you create a 'virtual' schema that contains type information but is not necessarily backed by real tables. The MockCatalogReader class, used in several of Calcite's tests, is a good example to follow.
