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).

• SqlParserFixture

Constructor Details

SqlParserTest

public SqlParserTest()

Method Details

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

protected SqlParserFixture sql(String sql)

expr

protected SqlParserFixture expr(String sql)

sqlParser

protected static SqlParser sqlParser(Reader source,
 UnaryOperator<SqlParser.Config> transform)

isDdl

public static org.hamcrest.Matcher<SqlNode> isDdl()

Returns a Matcher that succeeds if the given SqlNode is a DDL statement.

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)

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

@Test
protected void testMetadata()

testHoist

@Test
protected void testHoist()

Tests Hoist.

varToStr

protected static String varToStr(Hoist.Variable v)
