Vova Vysotskyi created CALCITE-4448:
---------------------------------------
Summary: Use TableMacro user-defined table functions with
QueryableTable
Key: CALCITE-4448
URL: https://issues.apache.org/jira/browse/CALCITE-4448
Project: Calcite
Issue Type: Improvement
Reporter: Vova Vysotskyi
Assignee: Vova Vysotskyi
Calcite widely uses {{QueryableTable}} during the query execution, and it also
provides the capabilities for creating user-defined table functions using
{{TableMacro}}. But currently, it is impossible to use such user-defined table
functions with the queriable table. Here is the sample test that demonstrates
this issue:
{code:java}
@Test void testQueryableTableWithTableMacro() throws SQLException {
TableMacro tableMacro = new TableMacro() {
@Override
public TranslatableTable apply(List<?> arguments) {
return new TableInRootSchemaTest.SimpleTable();
}
@Override
public List<FunctionParameter> getParameters() {
return Collections.emptyList();
}
};
try (Connection connection =
DriverManager.getConnection("jdbc:calcite:")) {
CalciteConnection calciteConnection =
connection.unwrap(CalciteConnection.class);
SchemaPlus rootSchema = calciteConnection.getRootSchema();
SchemaPlus schema = rootSchema.add("s", new AbstractSchema());
schema.add("simple", tableMacro);
ResultSet resultSet = connection.createStatement().executeQuery(
"select * from table(\"s\".\"simple\"())");
assertThat(CalciteAssert.toString(resultSet),
equalTo("A=\"foo\",B=5\n"
+ "A=\"bar\",B=4\n"
+ "A=\"foo\",B=3\n"));
}
}
{code}
This test fails with the following exception when trying to convert expressions
to the executable code:
