SQL Server Compact 3.5 includes support for showplans, which help assess and optimize queries. SQL Server Compact 3.5 uses the same showplan schema as SQL Server 2008 except SQL Server Compact 3.5 uses a subset of the operators. For more information, see the Microsoft Showplan Schema athttps:/...
For complex queries, the number of all possible permutations can be huge, so the query optimizer does not evaluate all possibilities but instead tries to find a plan that is "good enough" for a given query. This is because finding a perfect plan may not always be possible; and even when...
Complex script support SQL Server can support inputting, storing, changing, and displaying complex scripts. Complex scripts include the following types: Scripts that include the combination of both right-to-left and left-to-right text, such as a combination of Arabic and English text...
However, the point of the calls limit is to prevent too many long-running queries from a single connection and negatively affecting other connections.For example, if a connection makes 200 calls at the same time, and each call takes 50 seconds to execute, all other calls will fail with a ...
This wait occurs when queries cannot be compiled due to the amount of compile memory currently available. This mostly occurs due to large queries requiring an excessive amount of memory. SQL Server caps the amount of complex queries that can be compiled at once, so increasing the memory allocati...
and they are generally useful for people who want information from the system tables that is not provided by other mechanisms. This allows Transact-SQL procedures and DB-Library applications to access metadata without writing complex queries against the SQL Server system tables, and isolates the appl...
