Class SqlToRelTestBase

java.lang.Object

org.apache.calcite.test.SqlToRelTestBase

public abstract class SqlToRelTestBase
extends Object

SqlToRelTestBase is an abstract base for tests which involve conversion from SQL to relational algebra.

SQL statements to be translated can use the schema defined in MockCatalogReader; note that this is slightly different from Farrago's SALES schema. If you get a parser or validator error from your test SQL, look down in the stack until you see "Caused by", which will usually tell you the real error.
