hi folks.
we had this question directed at us so i thought to move it on to this discussion to see if any one had some ideas. thanks.
I have a question to you: how many UNION ALL SELECT “raw literal” subqueries can I use in one SQL query to Sybase Server?
I need to insert a batch of strings to temporary table. The most pretty syntax for this (according to Sybase restrictions) is to use the following query: “insert #tmp select “string1” union all select “string2” union all select …”.
Sybase documentation says the following:
The maximum number of subqueries within a single side of a union is 50.
The total number of tables that can appear on all sides of a union query is 256.
And what’s about my case of query? I’ve successfully inserted 500 entries in such way but what about maximum possible number of inserts?
