sql server - ALTER TABLE ... SWITCHing from regular table to partitioned table fails - Database Administrators Stack Exchange
When it mentioned check constraints on the table (when there was no check constraint), it did not occur to me that the lack of a check constraint was, in fact, the problem
ORACLE : STAGE1 : SERVER STAGE2: ONLY 1 DATABASE STAGE3: MORE THAN ONE SCHEMA IN DATABASE If you execute any script at serve level, because there is only one database, it can give you results. Help please as I am trying to set up the connection to the dbase where the user will only be able to see a select set of tables, views and with either userid pass word via ms sql mang console or ODBC have just select access to tables for users, keeping things locked down from the user
Either because you already have the data in a table, as in the case of table-valued parameters, or you skip the table entirely as you do with dynamic SQL or when you use many parameters. As I discussed above in the section Inline, Multi-Statement and Temp Tables, inline T-SQL functions gives the optimizer a degree of freedom which is not really good for its health
In this article we'll see how to use the Temporary tables and what are the necessary steps to be taken while using them and moreover sometimes it's required to add a column in Temporary tables dynamically
The lack of support for the UNIQUE option is no big deal since you can always define a PRIMARY KEY or UNIQUE constraint, which create a unique index underneath the covers. Since they already did the work in the parser, Microsoft decided to extend the support for such syntax to also disk-based tables, including table variables
The above listed differences are discussed in-detail with extensive list of examples in the below articles: Comparative Analysis of Temporary Table and Table Variable based on the aspects like Syntax, Storage Location and Transactions. Please try creating the below function, it will Error out with message: Msg 2772, Level 16, State 1, Procedure TempTable, Line 5 Cannot access temporary tables from within a function
Let's explore two examples: how to use fake temporary tables inside triggers and how to use fake temporary tables to execute stored procedures affecting a batch of changes. So, how can you send a data set to a stored procedure for further processing? Suppose you have a stored procedure called CheckInvoice, which converts proposed invoices into permanent ones
SQL Server Forums - SELECT QUERY OF TEMP TABLE
A global temp table is accessible by other sessions outside the session that created it, but it will be automatically dropped when either the session that created it, or the last active session that accessed it ends. I believe those are really the only differences between a global temp and a permanent table.I don't know if this provides a solution to your problem, but hopefully it adds some information that helps you decide what you can do

We discovered this with stored procedures that were written with table variable (the SQL Server docs say they're better than temp tables all the way around)
However, if a query references a temporary table and two temporary tables with the same name exist at that time, it is not defined which table the query is resolved against. Nested stored procedures can also create temporary tables with the same name as a temporary table that was created by the stored procedure that called it

Reply to this comment Derek Dieter 16 Sep 2011 at 12:19 pm Hi Kyaw, In this case, you do need the database name of TempDB because that is always where temporary tables are stored
The compile time table cardinality is stored in the plan and if the statement is executed again with the same cardinality (either due to flow of control statements or reuse of a cached plan) no recompile occurs. As a side bar, recompiles with Temp Tables can occur with the addition of data and whether the DDL for the temp table is interlaced with the DML or not
