Posted on by junior AX 1,552

Hi,

So i did this, but in the xml file i;m getting integer value for the enum and not text. How can i show it as text?

public static server str EnumField()
{

    return  strFmt('select top 1 EnumField from Table1 as table1 WHERE table1.PARTITION = %1 AND table1.DATAAREAID = %2 AND table1.Id2 = %3 AND table1.Id1 != %4 AND table1.Id3 = %5'
        , SysComputedColumn::comparisonField(tableStr(Table1View), identifierStr(Table1), fieldStr(Table1, Partition))
        , SysComputedColumn::comparisonField(tableStr(Table1View), identifierStr(Table1), fieldStr(Table1, DataAreaId))
        , SysComputedColumn::comparisonField(tableStr(Table1View), identifierStr(Table1), fieldStr(Table1, Id2))
        , SysComputedColumn::comparisonField(tableStr(Table1View), identifierStr(Table1), fieldStr(Table1, Id1))
        , SysComputedColumn::comparisonField(tableStr(Table1View), identifierStr(Table1), fieldStr(Table1, Id3))
         );

}

    Hi JuniorAX,

    You can use a switch statement to convert integer enum value to a string value

    It should be something like below

    private static str EnumField()
{
	
	str formattedValue = "'%1'";
	Map enumValues = new Map(Types::String, Types::String);
	
	enumValue.insert(enum2int(MyEnum::Value1), strFmt(formattedValue, enum2str(MyEnum::Value1)));

	return SysComputedColumn::switch(
		strFmt('select top 1 EnumField from Table1 as table1 WHERE table1.PARTITION = %1 AND table1.DATAAREAID = %2 AND table1.Id2 = %3 AND table1.Id1 != %4 AND table1.Id3 = %5'
        , SysComputedColumn::comparisonField(tableStr(Table1View), identifierStr(Table1), fieldStr(Table1, Partition))
        , SysComputedColumn::comparisonField(tableStr(Table1View), identifierStr(Table1), fieldStr(Table1, DataAreaId))
        , SysComputedColumn::comparisonField(tableStr(Table1View), identifierStr(Table1), fieldStr(Table1, Id2))
        , SysComputedColumn::comparisonField(tableStr(Table1View), identifierStr(Table1), fieldStr(Table1, Id1))
        , SysComputedColumn::comparisonField(tableStr(Table1View), identifierStr(Table1), fieldStr(Table1, Id3))
         ),
		enumValues,
		SysComputedColumn::returnLiteral(''));
}

    Hi Sergie,

    I didn't understand what do you mean  by this? what should i replace MyEnum::Value1 with?  there are alot of enums that can be returned why did you stick to value1?

    or do you want me to add all values? but this enum has more than 30 values

       enumValue.insert(enum2int(MyEnum::Value1), strFmt(formattedValue, enum2str(MyEnum::Value1)));

    also why the formatted type has " and '?

    Hi junior AX,

    you must put all enum values into the map.

    Hi JuniorAX,

    The idea is that you need to build the map: integer value - string value and you need to add all 30 values. You can use DictEnum class to iterate over all enum values if you don't want to paste 30 insert lines.

    String value should be wrapped with single quotes because it's required by SQL syntax, in SQL view related to your entity you will see a case statement like that:

    CAST(
	CASE 
		WHEN 1
			THEN 'Value2'
		WHEN 2
			THEN 'Value2'
		...
		ELSE ''
		END
	) AS NVARCHAR(20))
) AS EnumField
