temp-tables

I have a TSQL Stored Procedure tsql__sp__A which does two things: (a) Creates a temp table #tempTable that has SELECT data from a complex SELECT query. (b) Calls a CLR managed Stored Procedure clr__sp__B for each row that does computation on row parameters. Question: Is it possible to access #tempTable from CLR procedure clr__sp__B using the same connection context? (No, I don't want to move or create another #tempTable inside managed procedure) Thanks. Thank you Boj. However I found that when you use with a "context connections=true" it opens up all the SET Read Bol Article //The context

I want to have some information available for any stored procedure, such as current user. Following the temporary table method indicated here , I have tried the following: 1) create temporary table when connection is opened private void setConnectionContextInfo(SqlConnection connection) { if (!AllowInsertConnectionContextInfo) return; var username = HttpContext.Current?.User?.Identity?.Name ?? ""; var commandBuilder = new StringBuilder($@" CREATE TABLE #ConnectionContextInfo( AttributeName VARCHAR(64) PRIMARY KEY, AttributeValue VARCHAR(1024) ); INSERT INTO #ConnectionContextInfo VALUES(

How to insert the resultset given by the commands RESTORE FILELISTONLY RESTORE HEADERONLY RESTORE VERIFYONLY into an automatically generated temp table ? I would like to use a technique similar to (so the table is auto created, with all the columns matching the resultset's columns) SELECT * INTO #TempTable FROM (RESTORE FILELISTONLY FROM DISK = 'c:\Test\Test.bak') But this doesn't work. If I could populate a TempTable I could then be able to use the information contained in it in a following SQL Statement (in my case a restore DB statement in which I need to use some strings contained in the

I'm working with an Oracle 10g database, and I want to extract a group of records from one table, and then use that for pulling records out of a bunch of related tables. If this were T-SQL, I'd do it something like this: CREATE TABLE #PatientIDs ( pId int ) INSERT INTO #PatientIDs select distinct pId from appointments SELECT * from Person WHERE Person.pId IN (select pId from #PatientIDs) SELECT * from Allergies WHERE Allergies.pId IN (select pId from #PatientIDs) DROP TABLE #PatientIDs However, all the helpful pages I look at make this look like a lot more work than it could possibly be, so I

I read an excel sheet into a datagrid.From there , I have managed to read the grid's rows into a DataTable object.The DataTable object has data because when I make equal a grid's datasource to that table object , the grid is populated.

While looking for a way to temporarily save the search results when a user searches for a hotel free between particular dates i came across temporary tables. But certain questions are not answered even in mysql manual.... like... Will the temporary table be unique for each user that executes the script...? Or will it be overwritten when two different users run the script at the same time...? When will the table be destroyed..? When the user closes the browser window or just navigates away from the page in which the script runs...? Thanks for your clarifications... This is how i do it....

I need to get list columns of some temporary table (MyISAM) in MySQL in view like number column - name column . I need to know number of column with specific name. In advance, I can't know what is the number of column - I'm using dynamic sql with some variables to create temporary table. I can not use show columns... because I can't work with results of this function. I can't use INFORMATION_SCHEMA.COLUMNS because it does not contains columns of temporary table. Some ideas? Thanks in advance! 来源： https://stackoverflow.com/questions/10443672/list-of-temporary-table-columns-mysql

I'm working on a SQLite Database. The database is already filled, but I want to refactor it. Here is a sample of what I need to do: I currently have one table: CREATE TABLE Cars (ID INTEGER PRIMARY KEY, Name VARCHAR(32), TopSpeed FLOAT, EngineCap FLOAT); I want to split this into two tables: CREATE TABLE Vehicles (ID INTEGER PRIMARY KEY, Name VARCHAR(32), TopSpeed FLOAT); CREATE TABLE Cars (ID INTEGER PRIMARY KEY, VehicleID INTEGER CONSTRAINT FK_Cars REFERENCES [Vehicles](ID), EngineCap FLOAT); I have figured out to create a temporary table with the Cars table contents, and I can fill up the

I have a MySQL query which uses 3 tables with 2 inner joins. Then, I have to find the maximum of a group from this query output. Combining them both is beyond me. Can I break down the problem by storing the output of the first complicated query into some sort of temporary table, give it a name and then use this table in a new query? This will make the code more manageable. Thank you for your help. This is very straightforward: CREATE TEMPORARY TABLE tempname AS ( SELECT whatever, whatever FROM rawtable JOIN othertable ON this = that ) The temporary table will vanish when your connection closes

I run this query CREATE TEMPORARY TABLE usercount SELECT * FROM users I get this message Your SQL query has been executed successfully ( Query took 0.1471 sec ) But when I try to access the newly created table using SELECT * FROM usercount I get this error #1146 - Table 'abc_site.usercount' doesn't exist Not sure why, I need to mention that I've did a good share of googling beforehand. My version of PHPMyAdmin is 3.5.2.2 and MySQL 5.5.27 PHPMyAdmin (or rather PHP) closes the database connection after each screen. Thus your temporary tables disappear. You can put multiple SQL statements in the
