Class SqlParserTest

java.lang.Object
org.apache.calcite.sql.parser.SqlParserTest
public class SqlParserTest extends Object
A SqlParserTest is a unit-test for the SQL parser.

To reuse this test for an extension parser, override the fixture() method, calling SqlParserFixture.withConfig(UnaryOperator) and then SqlParser.Config.withParserFactory(SqlParserImplFactory).

    • fixture

      public SqlParserFixture fixture()
      Creates the test fixture that determines the behavior of tests. Sub-classes that, say, test different parser implementations should override.

    • sql

    • expr

      protected SqlParserFixture expr(String sql)

    • sqlParser

    • isDdl

      public static org.hamcrest.Matcher<SqlNode> isDdl()
      Returns a Matcher that succeeds if the given SqlNode is a DDL statement.

    • customMatches

      public static org.hamcrest.Matcher<SqlNode> customMatches(String description, Consumer<SqlNode> consumer)
      Returns a Matcher that calls a consumer and then succeeds. The consumer should contain custom code, and should fail if it doesn't like what it sees.

    • getReservedKeywords

      protected SortedSet<String> getReservedKeywords()

    • isReserved

      protected boolean isReserved(String word)
      Returns whether a word is reserved in this parser. This method can be used to disable tests that behave differently with different collections of reserved words.

    • keywords

      protected static SortedSet<String> keywords(@Nullable String dialect)

    • testCast

      @Test public void testCast()

    • testEmpty

      @Test public void testEmpty()
      Test case for [CALCITE-6986] Parser rejects SQL sources that produce an empty statement list.

    • testCaseExpression

      @Test public void testCaseExpression()

    • testTimeUnitCodes

      @Test protected void testTimeUnitCodes()
      Tests that EXTRACT, FLOOR, CEIL, DATE_TRUNC functions accept abbreviations for time units (such as "Y" for "YEAR") when configured via SqlParser.Config.timeUnitCodes().

    • testMetadata

    • testHoist

      @Test protected void testHoist()
      Tests Hoist.
