Example 1 with BinaryLiteral

use of io.trino.sql.tree.BinaryLiteral in project trino by trinodb.

the class TestSqlParser method testBinaryLiteral.

@Test
public void testBinaryLiteral() {
    assertExpression("x' '", new BinaryLiteral(""));
    assertExpression("x''", new BinaryLiteral(""));
    assertExpression("X'abcdef1234567890ABCDEF'", new BinaryLiteral("abcdef1234567890ABCDEF"));
    // forms such as "X 'a b' " may look like BinaryLiteral
    // but they do not pass the syntax rule for BinaryLiteral
    // but instead conform to TypeConstructor, which generates a GenericLiteral expression
    assertInvalidExpression("X 'a b'", "Spaces are not allowed.*");
    assertInvalidExpression("X'a b c'", "Binary literal must contain an even number of digits.*");
    assertInvalidExpression("X'a z'", "Binary literal can only contain hexadecimal digits.*");
