I need to show maxInspectionDate in my result but I can't figure out how to do it.
SELECT E.equipmentID, E.assetNumber, E.T5Code , E.InspectionDuration, E.Description,
E.AssetType, E.WorkingLimits
FROM Equipment E
WHERE EXISTS
(SELECT t.equipmentID, r.maxInspectionDate
FROM (
SELECT equipmentID, MAX(nextInspectionDate) as maxInspectionDate
FROM equipmentInspection
GROUP BY equipmentID
) r
INNER JOIN equipmentInspection t
ON t.equipmentID = r.equipmentID AND t.nextInspectionDate = r.maxInspectionDate)
I need to get all distinct values from 10 different tables that exist in the field [favoritesport] And each table holds close to 50K records so I am looking at 500,000 records to get distinct values for. Would the fastest, less intrusive way of achieving this be to just create a UNION ALL so run
Select Distinct([favoritesport]) from table1 Union Select Distinct([favoritesport]) from table2 Union Select Distinct([favoritesport]) from table3 etc etc etc
Is there any way to update multiple tables in a single query. I know we can write triggers. Apart from triggers, is there any other way available in SQL Server. I am using 2008R2.
select count(cars.carid) from Cars left join RentalOrders on cars.CarID=RentalOrders.CarRef where carid not in(selectRentalOrders.CarRef from RentalOrders)
when I wrote this above-query for sofiacarrental_v2.2 it shows 30 in the result but when I changed it this query to that:
select count(cars.carid) from Cars left join RentalOrders on cars.CarID=RentalOrders.CarRef where not exists (select RentalOrders.CarRef from RentalOrders)
I replaced not in with not exists it showed 0 in the result.there is any point in term of using them or I made a mistake in the second query?
i need to write a query that insert in A table if and only if the row does not exist already in the table (the source is a select statement). i tried the following:
insert into [A] select * from [B] where Not EXISTS (select * from [A])
table [A] is still empty, but it does not insert any thing! .. what i know is that the EXIST checks if the selected row exists in the subquery, ain't ?
We have a maintenance plan running everyday for rebuild and re-organisation of indexes. But, somehow its getting failed. Here is the script that we are running for rebuild or re-org.
/* Script to handle index maintenance Tuning constants are set in-line current values are; SET @MinFragmentation SET @MaxFragmentation SET @TrivialPageCount
In SQL 2012.A query that joins 2 table, with order by clause doesn't get sorted and the result set is not ordered. This happens when some of the columns in the where criteria are in a unique index which is the index that is used for the join between the 2 tables, and all the columns in the unique index are in the where criteria.In the query plan there is no component for sort.The work around was to drop the unique index, or change it to a non-unique index. Once this was done, the execution plan was changed to add the sort component (even when the index was changed to non-unique and the join was still using this index).
When I am initializing a transactional replication from SQL 2005 to Oracle 10g, SQL tries to drop tables that don't exist. The properties option for the articles specifically states "if the name is in use:". The name is not in use, yet SQL still tries to drop non-existent tables, which causes the replication to halt. Anyone seen this before, or have any ideas what to do about it?
I have two tables that will not drop in a Database. I'm running SQL 6.5 on a Compaq Proliant.
Symptoms: Both tables show up in sysobjects, sysindexes, and syscolumns. Both allow SELECT, sp_rename, and truncate, but just hang ISQL or the Enterprise Manager when I try to drop them. I ran a DBCC CheckTable on them with no errors reported. Any ideas??
Hi, I want to get the results of a query between 2 tables that exist in the same server but in 2 different databases. I want this query to be executed in a stored procedure (use the reults in a cursor), or if it's possible to be used in an ado dataset or a simple dataset in Delphi. Can this be done also if the two datases (MSSQL) exist in different servers?? Can anyone show an example of how to accomplish these tasks??
I have two SPs, call them Daily and Weekly. Weekly will always callDaily, but Daily can run on its own. I currently use a global temptable because certain things I do with it won't work with a local temptable or table variable.I have been trying to get code so that if the table already exists, itjust keeps going and uses it, but creates the temp table if it doesn'texist. Unfortunately, no matter how I try to do it, it always attemptsto create it, raising an error and breaking the code.create table ##load_file_log (id int identity(1,1),contentsvarchar(1000))insert into ##load_file_log (contents) values ('test record')IF object_id('tempdb..##load_file_log') IS not NULLprint 'exists'ELSEcreate table ##load_file_log (id int identity(1,1),contentsvarchar(1000))select * from ##load_file_logdrop table ##load_file_logIf I change it to IS NULL, the same error occurs (Server: Msg 2714,Level 16, State 1, Line 7There is already an object named '##load_file_log' in the database.)I have found one way to do it, but it seems a bit...clunky.IF object_id('tempdb..##load_file_log') IS NULLexec ('create table ##load_file_log (id int identity(1,1),contentsvarchar(1000))')I'll use that for now, but is there something I missed?Thanks.
Hello. I need some help constructing a query i need to run on my database. I need to add 2 fields to every table in my databse. However, some of the tables already have1 or both these fields so i need to somehow do a check if the dield already exists. If it does not create the fields. Im using a MS SQL express 2005 server. Could anyone help me construct this. Im pretty novice at SQL. Thanks.
What SQL statement can i run to return a list of new tables or columns that exist in the Sales Database on Server A, which do not exist in the Sales Database in Server B.
Hi all: for example: testDataContext db=new testDataContext();var res=db.tables.single(p=>p.columnName=="hi"); if there is a record in the database, it works well, but if there isn't , it will throw an exception, then , How could I know the record exists or not ? I don't think exception is a resonable way. and in my opinion, there should be--------even must be ------a resonable way , to evaluate the query result to a bool variable, then program could judge the bool variable like : if(bExist) show("yes, I find it");else show("sorry, the record doesn't exist in the database"); I can't imagine I got the bool variable via exception... thanks to all..
I have a dynamic query in the stored procedure, and the code looks something like this:
SET @section_test = 'SELECT sectioncode FROM ' + @tablename + ' WHERE sectioncode = "' + @condition + '"' EXEC (@section_test)
What I need to do is try to check if the query returns any values using EXISTS (possibly), but at the same time I don't want to return the results of that dynamic query's select statement in my stored procedure. Is it possible?
The 2nd table is for storing product codes for customers, in other words, one product can have different ProductCode for different customers. But some customers do not have ProductCode for a ProductID.
I want to create a query to return all the Products and its ProductCode (null is valid) for a specific customer.
I tried:
SELECT dbo.tblProductCodes.ProductCode, dbo.tblProductCodes.CustomerID, dbo.tblProducts.ProductName, dbo.tblProducts.ProductID FROM dbo.tblProducts LEFT OUTER JOIN dbo.tblProductCodes ON dbo.tblProducts.ProductID = dbo.tblProductCodes.ProductID WHERE dbo.tblProductCodes.CustomerID = 2
But the query left out all products that does not have ProductCode value in tblProductCodes table for CustomerID = 2. I want all the ProductName returned from query and render null or empty string for ProductCode value if the code does not exist in tblProductCodes table for the customer.
For each customer, I want to add all of their telephone numbers to a different column. That is, multiple columns (depending on the number of telephone numbers) for each customer/row. How can I achieve that?
I want my output to be
CUSTOMER ID, FIRST NAME, LAST NAME, TEL1, TEL2, TEL3, ... etc
Each 'Tel' will relate to a one or more records in the PHONES table that is linked back to the customer.
In our production database we are looking top 10 columns in all the tables, for this using the below script, output was showing only one table how we get the all the tables top 10 ...
I have a query that performs a comparison between 2 different databases and returns the results of the comparison. It returns 2 columns. The 1st column is the value of the object being compared, and the 2nd column is a number representing any discrepancies.What I would like to do is use the results from this 1st query in the where clause of another separate query so that this 2nd query will only run for any primary values from the 1st query where a secondary value in the 1st query is not equal to zero.I was thinking of using an "IN" function in the 2nd query to pull data from the 1st column in the 1st query where the 2nd column in the 1st query != 0, but I'm having trouble ironing out the correct syntax, and conceptualizing this optimally.
While I would prefer to only return values from the 1st query where the comparison value != 0 in order to have a concise list to work with, I am having difficulty in that the comparison value is a mathematical calculation of 2 different tables in 2 different databases, and so far I've been forced to include it in the select criteria because the where clause does not accept it.Also, I am not a DBA by trade. I am a system administrator writing SQL code for reporting data from an application I support.
I have a column colC in a table myTable that has a value (e.g. '0X'). The position of a non-zero character in column colC refers to the ordinal position of another column in the table myTable (in the aforementioned example, colB).
To get a column name (i.e., colA or colB) from table myTable, I can join ("ON cte.pos = cn.ORDINAL_POSITION") to INFORMATION_SCHEMA.COLUMNS for that table catalog, schema and name. But I want to show the value of what is in that column (e.g., 'ABC'), not just the name. Hoping for:
COLUMN_NAME Value ----------- ----- colB 123 colA XYZ
I've tried dynamic SQL to no success, probably not executing the concept correctly...
I am trying to optimize a stored procedure in SQL 2008. When I look at an actual execution plan generated from when I run it in SSMS it shows a table being used in the plan that has no relation to what is actually in the query script and this is where the biggest performance hit occurs.
I've never seen a table show up before that wasn't part of the query. why this might occur and how to correct it? I can't just change the query script because the table in question isn't there.
I need to select Server1, Server2, Server3 and other servers that does not have correct value in Table2. Results should return server name and number that server does not have like:
Server2 | 3 Server3 | 1 Server3 | 3
Table1 is updated time to time, Table2 - static table. The best would be to avoid loop or cursor. Is that possible to get these results in one query?
I have two global temp tables in my stored procedure.Is it possible for me to make the execution of a stored procedure dynamic. Based on a flag parameter value I should get the result set from first temp table and viceversa ex: If my flag is 0.I should be able to get the result set from ##temp1 (select * from ##temp1).If my flag is 1.I should be able to get the result set from ##temp2 (select * from ##temp2).
We are accessing a database through Linked Servers. That database has a bunch of views.We are able to get a list of columns for our views by querying [syscolumns]. However, how do we find out which of those columns have primary keys?
I have two temp. tables. I am trying to show the agents how makes the sales and the ones how didnt make sales based on the time that they clock in. One table is called #sales which has only the agents that make sales and other tables is #hours which has both agents that do not make sale. the problem is that I can not get both agents to show on my report. I tried different ways but I could not. #sales table uses (select statement from AmountStats table that stores only the agents who make sale). #hours table uses different tables to store all gents who makes sale and ones that are not making sale.
