Example 1 with FullQualifedNameFieldProvider

use of io.crate.analyze.relations.FullQualifedNameFieldProvider in project crate by crate.

the class ExpressionAnalyzerTest method testQuotedSubscriptExpression.

@Test
public void testQuotedSubscriptExpression() throws Exception {
    ExpressionAnalyzer expressionAnalyzer = new ExpressionAnalyzer(functions, new SessionContext(0, EnumSet.of(Option.ALLOW_QUOTED_SUBSCRIPT), null), paramTypeHints, new FullQualifedNameFieldProvider(dummySources), null);
    ExpressionAnalysisContext expressionAnalysisContext = new ExpressionAnalysisContext();
    Field field1 = (Field) expressionAnalyzer.convert(SqlParser.createExpression("obj['x']"), expressionAnalysisContext);
    Field field2 = (Field) expressionAnalyzer.convert(SqlParser.createExpression("\"obj['x']\""), expressionAnalysisContext);
    assertEquals(field1, field2);

    assertEquals("myObj['x']", field3.path().toString());
    Field field4 = (Field) expressionAnalyzer.convert(SqlParser.createExpression("\"myObj['x']['AbC']\""), expressionAnalysisContext);
    assertEquals("myObj['x']['AbC']", field4.path().toString());
}

Example 2 with FullQualifedNameFieldProvider

use of io.crate.analyze.relations.FullQualifedNameFieldProvider in project crate by crate.

the class ExpressionAnalyzerTest method testAnalyzeSubscriptFunctionCall.

@Test
public void testAnalyzeSubscriptFunctionCall() throws Exception {
    // Test when use subscript function is used explicitly then it's handled (and validated)
    // the same way it's handled when the subscript operator `[]` is used
    ExpressionAnalyzer expressionAnalyzer = new ExpressionAnalyzer(functions, new SessionContext(0, EnumSet.of(Option.ALLOW_QUOTED_SUBSCRIPT), null), paramTypeHints, new FullQualifedNameFieldProvider(dummySources), null);

    Function function = (Function) expressionAnalyzer.convert(subscriptFunctionCall, expressionAnalysisContext);
    assertEquals("subscript(_array(Literal{obj, type=string}),Literal{1, type=integer})", function.toString());
}
