Yep. You just need to CAST the first column as varchar:
,CAST(TEN.[tncy-sys-ref] AS varchar(10))
+ CASE WHEN PER.[GENDER] = 'M' THEN '1'
WHEN PER.[GENDER] = 'F' THEN '2'
ELSE '0'END AS 'ID'
SQL DBA,SQL Server MVP(07, 08, 09) Prosecutor James Blackburn, in closing argument in the Fatal Vision murders trial:
If in the future, you should cry a tear, cry one for them [the murder victims]. If in the future, you should say a prayer, say one for them. And if in the future, you should light a candle, light one for them.
