             Summary: Make type conversion documentation consistent with behavior and tests
                 Key: CALCITE-5485
                 URL: https://issues.apache.org/jira/browse/CALCITE-5485
             Project: Calcite
          Issue Type: Bug
            Reporter: Julian Hyde


Make type conversion documentation consistent with behavior and tests. Use the following steps:
 * Create an internal map that, for each pair of data types, says whether conversion is implicit, explicit, or disallowed
 * Run tests based on that map
 * In {{{}DocumentationTest{}}}, generate an HTML table of that mapping, and check that that table is consistent with the one in the [SQL reference|https://calcite.apache.org/docs/reference.html#implicit-type-conversion].

I know of two errors in the table:
 * The table says that you can explicitly cast from INT to TIMESTAMP (see CALCITE-5483); this should be disallowed;
 * The table says that you can explicitly cast from DECIMAL to BOOLEAN (see CALCITE-4777); this should be disallowed.

There may be others.
