[jira] [Created] (CALCITE-3424) AssertionError thrown for
user-defined table function with array argument
Igor Guzenko created CALCITE-3424:
-------------------------------------
Summary: AssertionError thrown for user-defined table function with array argument
Key: CALCITE-3424
URL: https://issues.apache.org/jira/browse/CALCITE-3424
Project: Calcite
Issue Type: Bug
Components: core
Affects Versions: 1.21.0
Reporter: Igor Guzenko
Assignee: Igor Guzenko
*Steps to reproduce:*
*1.* Add method with list parameter to Smalls.java
{code:java}
public static final Method GENERATE_STRINGS_2_METHOD =
Types.lookupMethod(Smalls.class, "generateStrings2", List.class);
public static QueryableTable generateStrings2(final List<Integer> list) {
return generateStrings(list.size());
}
{code}
*2.* Add test method which uses new user-defined table function to TableFunctionTest.java
{code:java}
@Test public void testTableFunction2() throws SQLException {
try (Connection connection = DriverManager.getConnection("jdbc:calcite:")) {
CalciteConnection calciteConnection =
connection.unwrap(CalciteConnection.class);
SchemaPlus rootSchema = calciteConnection.getRootSchema();
SchemaPlus schema = rootSchema.add("s", new AbstractSchema());
final TableFunction table =
TableFunctionImpl.create(Smalls.GENERATE_STRINGS_2_METHOD);
schema.add("GenerateStrings2", table);
final String sql = "select *\n"
+ "from table(\"s\".\"GenerateStrings2\"(5,4,3,1,2)) as t(n, c)\n"
+ "where char_length(c) > 3";
ResultSet resultSet = connection.createStatement().executeQuery(sql);
assertThat(CalciteAssert.toString(resultSet),
equalTo("N=4; C=abcd\n"));
}
}
{code}
Execution result produced by such test method is the following stack trace:
{code:none}
java.lang.AssertionError: use createArrayType() instead

*Tip:* In scope of CALCITE-3238 was added new assertion to *_SqlTypeFactoryImpl.assertBasic(...)_* method, and now this check can't be
ignored inside _*JavaTypeFactoryImpl.toSql(typeFactory, type)*_ static method.
