How do I use EXEC(@SQL) or EXEC SP_EXECUTESQL(@SQL) with Common Table Expressions?
Below does not work.
WITH CTE_Customer (ID, Name)
AS
(
EXEC (@strSqlCommand)
)
The short answer is that you cant:
http://msdn.microsoft.com/en-us/library/ms175972.aspx says:
“The CTE_query_definition must meet the same requirements as for creating a view”
Which basically says that you’re restricted to SELECT statements only.
Some workarounds might include using temp tables or table variables, but it really depends on context.
