with a table without a primary key or unique key? If your table does not has a unique index (or a PRIMARY KEY constraint or UNIQUE key constraint, both of which create a U Nique index behind the scenes), then your dynamic cursor is converted to a static cursor. And all static cursors must is read only. If one of the tables referenced by the cursor has no unique index, the cursor would be converted to STATIC. And STATIC cursors is read-only. See Using
When I recently made a report using SSRS 2005, when I called a data source with a temporary table, the system would make an error and would not be able to go to the next step of the wizard as follows:
There is a error in the query. Invalid object name ' #temptb '.
After research, think of the following three solutions:
1. Use table variables instead of temporary tables, which avoids the syntax error of SSRS 2005, the disadvantage is that if the am

Oracle uses query to create a table:Create Table dept30

clustered index makes the data in the table orderly based on the key-value contact. Deciding which key value to use as a clustered key is an important factor, and when traversing to the leaf level, you can get the data itself rather than simply getting a pointer to the data (nonclustered index data is not overwritten). The clustered index has a row in the Sys.partitions area, where the index uses index_id = 1per partition, and by default, the clustered index is a single partition. If the cluste
