What are the capacities of Access, SQL Server, and MSDE?
Here are some guidelines for database size, object number and naming limitations contrasted across Access 2000/XP, SQL Server 7.0, SQL Server 2000, and MSDE 2000. The main reason for this chart was to answer the question "how many rows can I get into a table?" -- which doesn't have a direct answer, but is limited by many of the variables listed below (not to mention disk space!).
| Parameter | ||||
|---|---|---|---|---|
- Using a federated database in SQL Server 2000, you can have 32,767 databases of 1,048,516 TB each, which is probably more space than anyone will ever need (though that phrase itself has proven dangerous to say <G>).
- This is how many concurrent users Access will allow, however this number is much smaller when Access is used in a web-based environment (see Article #2195).
- SQL Server allows 32,767 concurrent connections, or the number of licenses allowed, whichever is lower.
- MSDE has a performance throttler that kicks in when more than 5 workloads / batches are being run at once (see Article #2343).
- The Query Designer interface in Access limits you to 199 parameters, though it is possible (but not recommended) to create a query with even more parameters.
