SQL 2012 :: Create Random Alphanumeric Characters For Primary Key Values

Feb 11, 2015

For a new project. I need to create random alphanumeric characters as primary key values when inserting a record.

eg: cmSbXsFE3l8

It can start from 4 digit characters and can grow to 6, 7 as required

The database will involve more than 10000 concurrent users.

I don't want to use guid or auto increment integer or sequence.

Set Name Of Primary Key In The CREATE TABLE

Apr 28, 2008

I think there has to be a way to do this but I'm not seeing it.

I would like to set the names of my primary keys in the CREATE TABLE statements. I like this for documentation so it's very clear what the PK name is. When the system generates the key names, it always add the number suffix at the end. I would need to do this both when the PK is a single column and when it is multiple columsn (see examples below).

Thanks very much for your assistance.


CREATE TABLE dbo.SecAppRole1 (

app_id INT IDENTITY(1,1),

app_name_field VARCHAR(128) NOT NULL PRIMARY KEY ,

app_role VARCHAR(128) NOT NULL,

app_role_password VARCHAR(50) NOT NULL)


CREATE TABLE dbo.SecUserAppPermission1 (

app_id INT NOT NULL,

windows_user_name VARCHAR(128) NOT NULL,

user_permission CHAR(01) NOT NULL,

PRIMARY KEY CLUSTERED (app_id ASC, windows_user_name ASC))

SQL Server 2012 :: Insert Foreign Key Value Into Primary Table?

Oct 2, 2015

In a special request run, I need to update locker and lock tables in a sql server 2012 database, I have the following 2 table definitiions:

CREATE TABLE [dbo].[Locker](
[lockerID] [int] IDENTITY(1,1) NOT NULL,
[schoolID] [int] NOT NULL,
[number] [varchar](10) NOT NULL,
[lockID] [int] NULL
CONSTRAINT [PK_Locker] PRIMARY KEY NONCLUSTERED

[code]....

The locker table is the main table and the lock table is the secondary table. I need to add 500 new locker numbers that the user has given to me to place in the locker table and is uniquely defined by LockerID. I also need to add 500 new rows to the corresponding lock table that is uniquely defined in the lock table and identified by the lockid.

Since lockid is a key value in the lock table and is uniquely defined in the locker table, I would like to know how to update the lock table with the 500 new rows. I would then like to take value of lockid (from lock table for the 500 new rows that were created) and uniquely place those 500 lockids uniquely into the 500 rows that were created for the lock table.

I have sql that looks like the following so far:

declare @SchoolID int = 999
insert into test.dbo.Locker ( [schoolID], [number])
select distinct LKR.schoolID, A.lockerNumber
FROM [InputTable] A
JOIN test.dbo.School SCH ON A.schoolnumber = SCH.type and A.schoolnumber = @SchoolNumber
JOIN test.dbo.Locker LKR ON SCH.schoolID = LKR.schoolID
AND A.lockerNumber not in (select number from test.dbo.Locker where schoolID = @SchoolID)
order by LKR.schoolID, A.lockerNumber

I am not certain how to complete the rest of the task of placing lockerid uniquely into lock and locker tables?

SQL 2012 :: Auto ID Primary Key Specified As Int And Table Data Is Deleted Periodically?

Jun 25, 2015

I have a table that has a primary key that is auto incremented by 1. This table's data is cleared out periodically and as data gets added the auto id primary key continues to increase in numeric value. Once the data is cleared from the table the auto id names could be used again(the eventId is not stored) Currently the eventID is at 26,581,399. I know the maximum int value is 2,147,483,647.

How should I handle this? or rebuild the table every time the data is cleared(problematically)?

SQL 2012 :: Apply Primary Key On A Huge Table So Downtime Is Minimal?

Jul 30, 2015

I have a table (named table1) with 20million rows. It takes around 11 minutes to apply the primary key to this table. There are some tables with over 100 million rows so based on the previous time if my calculations are correct it will take close to an hour apply this primary key for tables with around 100 million rows.

My current solution is to create another table (named table2) with no indexs or primary keys. Pump over only like 5 days worth of data, then apply the primary key. Then have a script that will eventually populate table2 with the rest of the data gradually. When I say gradually I mean like insert like every 100k per hour or something. Keep in mind this table2 is heavily updated with new records.

How To Automatically Create New Records In A Foreign Table When Inserting Records In A Primary Table.

Sep 13, 2006

Ok, I'm really new at this, but I am looking for a way to automatically insert new records into tables.  I have one primary table with a primary key id that is automatically generated on insert and 3 other tables that have foreign keys pointing to the primary key.  Is there a way to automatically create new records in the foreign tables that will have the new id?  Would this be a job for a trigger, stored procedure?  I admit I haven't studied up on those yet--I am learning things as I need them. Thanks.

SQL Server 2012 :: Stored Procedures Compiles Even When There Is No CREATE TABLE For A Temp Table

Feb 11, 2015

i am inserting something into the temp table even without creating it before. But this does not give any compilation error. Only when I want to execute the stored procedure I get the error message that there is an invalid temp table. Should this not result in a compilation error rather during the execution time.?

--create the procedure and insert into the temp table without creating it.
--no compilation error.
CREATE PROC testTemp

INSERT INTO #tmp(dt)
SELECT GETDATE()

WITH

(

FIELDTERMINATOR = ',',

ROWTERMINATOR = ''

)

GO

========================================
The 3 csv files were successfully imported into the ChemDatabase of my SSMSE.

2 questions to ask:
(1) How can I designate the Primary and Foreign Keys to these 3 dbo Tables?
Should I do this "designate" thing after the 3 dbo Tables are done or during the "Importing" period?
(2) How can I set up the relationships among these 3 dbo Tables?

Please help and advise.

Thanks in advance,

DB Design :: Script To Create Table With Primary Key Non-clustered And Clustered Index

Aug 28, 2015

I desire to have a clustered index on a column other than the Primary Key. I have a few junction tables that I may want to alter, create table, or ...

I have practiced with an example table that is not really a junction table. It is just a table I decided to use for practice. When I execute the script, it seems to do everything I expect. For instance, there are not any constraints but there are indexes. The PK is the correct column.

CREATE TABLE [dbo].[tblNotificationMgr](
[NotificationMgrKey] [int] IDENTITY(1,1) NOT NULL,
[ContactKey] [int] NOT NULL,
[EventTypeEnum] [tinyint] NOT NULL,

SQL 2012 :: Create Table With Both Keys As Foreign (error)

Dec 15, 2014

I'm trying to create a table in Microsoft Server Management Studio 2012. The table has two fields which are both foreign keys.

I created the following:

create table tblRoomEquipment(
RoomID nvarchar(8),
EquipmentType nvarchar(1),
foreign key (RoomID) references tblRoom(ID),
foreign key (EquipmentType) references tblEquipment(Type)
)

Both tblRoom and tblEquipment have the red line error which when I highlight say the they both reference an invalid table!

Both tables are there and have primary keys defined as ID & Type. I have searched around and all I could find was that there maybe a permission problem.

SQL Server 2012 :: Create A Table That Would Represent Workload For Each Shop

Mar 19, 2015

I am trying to create a table that would represent a workload for each shop. In order to do that I need to have WorkLoad table and ShopWorkLoad table which is actually just aggregation of WorkLoad.

WorkLoad contains a list of following items:

current orders that are in the process (one select statement)
scheduled orders (another select statement)
expected orders (third select statement) that come through a third-party system

All of this needs to be live. So, for example, as soon as order is added to Order table it should be included in WorkLoad if certain conditions are met. Same goes for scheduled orders (which come from another table). Expected orders will be loaded on a daily bases (based on historical data).

ShopWorkLoad table is aggregation of WorkLoad table.

Currently I did it this way:

Added after insert/update trigger on Order table: when order is created/updated, if it meets certain conditions, it should be inserted in WorkLoad, otherwise remove it from workload if it's in there and doesn't meet conditions

Added after insert/update trigger on Schedule table: when order is scheduled, if it meets certain conditions, it should be inserted in WorkLoad, otherwise remove it from workload if it's in there and doesn't meet conditions

Running daily job that populates WorkLoad table with expected orders based on historical values

Final step is to create an indexed view vShopWorkLoad

My biggest concern is usage of triggers which call pretty complex logic to determine whether item should be added to workload or not.

One other option was to create vWorkLoad view and somehow make it an indexed view but currently I don't see a way of doing that because the query consists of 4 union select statements, below is pseudo example. But even if doing it that way, how to build aggregated indexed view on top of vWorkLoad indexed view?

Third option is to use sql agent job which would run every x seconds (maybe 20) and it would execute all of these queries to populate WorkLoad table with delay of 10-20 seconds, but I am still not sure if this is acceptable to the client.

Fourth option is to create 3 or 4 indexed view where sum of them makes a workload. Then, ShopWorkLoad view would be built on top of these 3 or 4 indexed views, but in this case I don't know how this would affect performance since ShopWorkLoad query would be often queried.

Example of workload pseudo query:

select
WorkLoadType = 'Order in process',
OrderId,
ShopId,
...
from
Order

SQL Server 2012 :: How To Create Staging Table To Handle Incremental Load

Jan 2, 2014

We are designing a Staging layer to handle incremental load. I want to start with a simple scenario to design the staging.

In the source database There are two tables ex, tbl_Department, tbl_Employee. Both this table is loading a single table at destination database ex, tbl_EmployeRecord.

The query which is loading tbl_EmployeRecord is, SELECT EMPID,EMPNAME,DEPTNAME FROM tbl_Department D INNER JOIN tbl_Employee E ON D.DEPARTMENTID=E.DEPARTMENTID.

Now, we need to identify incremental load in tbl_Department, tbl_Employee and store it in staging and load only the incremental load to the destination.

The columns of the tables are,

tbl_Department : DEPARTMENTID,DEPTNAME

tbl_Employee : EMPID,EMPNAME,DEPARTMENTID

tbl_EmployeRecord : EMPID,EMPNAME,DEPTNAME

How to design the staging for this to handle Insert, Update and Delete.

SQL 2012 :: Generating CREATE TABLE Scripts For Large Number Of Tables

Feb 11, 2014

Other than right-clicking on each individual table in SSMS and generating a CREATE script, is there a simple way to generate CREATE TABLE scripts for tables within a given database?

Background: I have a bunch of tables in one database, and I would like to add tables to a second database that have the same names and basic structures of some of the tables from the first database.

I do not need to transfer any data from the tables, this is a seperate project that will use a similar data structure. I just want to generate the CREATE TABLE scripts for 30ish tables within the first database, and then I'll tweak the scripts as appropriate and run them against the new database.
