------------------------------------
Summary: Support convert TableFunctionScan to SqlNode
Key: CALCITE-3481
URL: https://issues.apache.org/jira/browse/CALCITE-3481
Project: Calcite
Issue Type: Improvement
Reporter: Wang Yanlin
Currently, converting *TableFunctionScan* to sql is not supported, doing this
will cause exception.
Add the following test case in *RelToSqlConverterTest* to reproduce.
{code:java}
@Test public void testTableFunctionScan() {
final String query = "SELECT *\n"
+ "FROM TABLE(DEDUP(CURSOR(select \"product_id\", \"product_name\"\n"
+ "from \"product\"), CURSOR(select \"employee_id\", \"full_name\"\n"
+ "from \"employee\"), 'NAME'))";
final String expected = "SELECT *\n"
+ "FROM TABLE(DEDUP(CURSOR ((SELECT \"product_id\", \"product_name\"\n"
+ "FROM \"foodmart\".\"product\")), CURSOR ((SELECT \"employee_id\",
\"full_name\"\n"
+ "FROM \"foodmart\".\"employee\")), 'NAME'))";
sql(query).ok(expected);
}
{code}
The stack trace of exception is
