Exist Join

Hi

I have this query below :

select UPDimAttrProductFamilyValue from EcoResProductParameters
join DisplayValue , DimensionAttributeValueSet,DimensionAttributeValue from DimensionAttributeValueSetItem
where DimensionAttributeValueSetItem.DisplayValue == EcoResProductParameters.UPDimAttrProductFamilyValue
join recid from DimensionAttributeValue
where DimensionAttributeValue.recid == DimensionAttributeValueSetItem.DimensionAttributeValue
join UPDimensionAttributeRecId from LedgerParameters
where LedgerParameters.UPDimensionAttributeRecId == DimensionAttributeValue.DIMENSIONATTRIBUTE
join RecId from DimensionAttributeValueSet
where DimensionAttributeValueSet.recid == DimensionAttributeValueSetItem.DimensionAttributeValueSet
&& DimensionAttributeValueSet.recid == AgreementLine.DefaultDimension;
{
_dimAttrValue = EcoResProductParameters.UPDimAttrProductFamilyValue;
}

I am currently checking if the Displayvalue stored in EcoResProductParameters match the agreementline dimension value.

I need to transform this in exist join.

Can this be done?

Thanks.
