Oracle table exist query searching tables in all database? - sql

I have 20 oracle database in my machine when i am trying to run below script it searching the table in all the database how to tell query to search on particular or single database .
if not exists (select * from dba_tables where table_name='Default')
create table Default (
FolderType [VARCHAR](4) NOT NULL,
FeeCode [INT] NOT NULL,
StatusCode [INT] NOT NULL,
CalculationOrder [INT] NULL,
FeeAmount] [numeric](14, 2) NULL,
BillFlag] [CHAR](1) NULL,
Comments] [VARCHAR](4000) NULL,
)
go
ALTER TABLE Default ADD CONSTRAINT Default_PK PRIMARY KEY (FolderType, FeeCode, StatusCode)
GO

Using user_tables instead of dba_tables will give you the tables only in the user/schema you are logged in.

Insert a single Table into Multiple Databases

I am trying to insert a table into multiple databases.
I have figured out how to make it insert the single table into all of the Databases but I need it to exclude about 10 databases like the master, model, tempdb, msdb, then I have some others as well.
EXEC sp_msforeachdb
'
USE ?;
IF [?] NOT IN master, model, tempdb,
CREATE TABLE [?].[dbo].[FaceEnrollments](
[EmployeeNo] [varchar](10) NOT NULL,
[TIN] [varchar](20) NOT NULL,
[irFaceTemplate] [varchar](max) NULL,
[faceBitmap] [varchar](max) NULL,
[faceAttestationAccepted] [bit] NULL,
[EnrollmentDateTime] [datetime] NULL,
CONSTRAINT [PK_FaceEnrollments] PRIMARY KEY CLUSTERED
(
[EmployeeNo] ASC,
[TIN] ASC
)
);
';
This is what I got so far to add the table to all databases.
I have tried multiple things to exclude databases from this, but I cannot figure it out.
I was hoping someone could help me out. Please and Thank you!
you can adjust your dynamic query to this:
EXEC sp_msforeachdb
'
IF ''?'' NOT IN (''master'', ''model'', ''tempdb'')
CREATE TABLE ?.[dbo].[FaceEnrollments](
[EmployeeNo] [varchar](10) NOT NULL,
[TIN] [varchar](20) NOT NULL,
[irFaceTemplate] [varchar](max) NULL,
[faceBitmap] [varchar](max) NULL,
[faceAttestationAccepted] [bit] NULL,
[EnrollmentDateTime] [datetime] NULL,
CONSTRAINT [PK_FaceEnrollments] PRIMARY KEY CLUSTERED
(
[EmployeeNo] ASC,
[TIN] ASC
)
);
';
Also I recommand the better and more flexible sp originally created by Aaron Bertrand, you can download from Github for free :
SQL-Server-First-Responder-Kit/sp_ineachdb
which you can use exclude_list or exclude_pattern parameter to exclude databases:
exec [dbo].[sp_ineachdb]
#exclude_list = 'List of excluded databases'
#command = 'CREATE TABLE [dbo].[FaceEnrollments](...)'

Timestamp column not saving data in sql table

Hi I am designing table called user-registration with few fields. I have created date and updated date and requirement is to put time stamp for created and updated fields. I googled and found only one time stamp we can have per table and value will be inserted automatically and no need to supply value to it. Please correct me if i am wrong. Currently when i insert row of data to table i am getting in time stamp field. Below is my table structure.
CREATE TABLE [dbo].[NCT_UserRegistration](
[User_Id] [int] IDENTITY(1,1) NOT NULL,
[User_EmailId] [varchar](255) NULL,
[User_Password] [varchar](512) NULL,
[User_Name] [varchar](255) NULL,
[User_MobileNum] [varchar](20) NULL,
[User_Status] [varchar](15) NULL CONSTRAINT chk_Status CHECK ([User_Status] IN ('ENABLED', 'DISABLED')),
[User_Role] [varchar](20) NULL CONSTRAINT chk_Role CHECK ([User_Role] IN ('SUPER_ADMIN','PROJECT_ADMIN')),
[User_CreatedDate] [timestamp] NULL,
[User_UpdatedDate] [datetime] NULL,
[Name] [varchar](30) NULL
)
I tried as below.
ALTER TABLE [NCT_UserRegistration]
ALTER COLUMN [User_CreatedDate] TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP
and ended up with Incorrect syntax near the keyword 'DEFAULT'.
Any help would be appreciated. Thank you.
Try this in Table structure :-
User_CreatedDate TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP

SQL Server : How to combine multiple database into one database?

From my original database, I made changes to some tables with columns in the table, I want to merge them into a single database. New database just add some table and old table add some columns.
How to merge multiple database into one database?
SQL example:
CREATE TABLE [dbo].[Item]
(
[ItemID] [nchar](10) NOT NULL,
[Money] [bigint] NOT NULL,
[ItemName] [bigint] NOT NULL,
[MoneyType] [bigint] NOT NULL,
CONSTRAINT [PK_Item]
PRIMARY KEY CLUSTERED ([ItemID] ASC) ON [PRIMARY]
) ON [PRIMARY]
GO
CREATE TABLE [dbo].[Account]
(
[Index] [int] IDENTITY(1,1) NOT NULL,
[AccountID] [nchar](10) NOT NULL,
[AccountName] [int] NOT NULL,
[ItemList] [int] NOT NULL,
) ON [PRIMARY]
GO
CREATE TABLE [dbo].[Money]
(
[AccountID] [nchar](10) NOT NULL,
[Money] [bigint] NOT NULL,
[MoneyType] [bigint] NOT NULL,
CONSTRAINT [PK_Money]
PRIMARY KEY CLUSTERED ([AccountID] ASC) ON [PRIMARY]
) ON [PRIMARY]
GO
-> Nick.McDermaid: use the schema compare tool in Visual Studio (various free editions) which will create a change script!
This will combine them onto DBCombined.Account if the Account table does NOT exist yet: the SELECT INTO code creates the target table. You would then need to add any indexes from the original tables. Also, "SELECT *" should really be broken out, listing each field, because if you have an ID field it will contain duplicates. Better to leave ID off during the insert and then go back and add an identity column.
USE DBCombined
GO
SELECT *
INTO Account
FROM (
SELECT *
FROM DB1.dbo.Account
UNION ALL
SELECT *
FROM DB2.dbo.Account
) Acct

How do I insert into two tables all at once in a stored procedure? [duplicate]

How can I INSERT data into two tables simultaneously in SQL Server?
Doing a project for school so any help would be great thank you!
I have two tables - how do I insert into two tables? So both tables are linked.
First table is called Customer with primary key called CID that auto increments
CREATE TABLE [dbo].[Customer](
[CID] [int] IDENTITY(1,1) NOT NULL,
[LastName] [varchar](255) NOT NULL,
[FirstName] [varchar](255) NOT NULL,
[MiddleName] [varchar](255) NULL,
[EmailAddress] [varchar](255) NOT NULL,
[PhoneNumber] [varchar](12) NOT NULL
CONSTRAINT [PK__CInforma__C1F8DC5968DD69DC] PRIMARY KEY CLUSTERED
(
And a second table called Employment that has a foreign key linked to the parent table
CREATE TABLE [dbo].[Employment](
[EID] [int] IDENTITY(1,1) NOT NULL,
[CID] [int] NOT NULL,
[Employer] [varchar](255) NOT NULL,
[Occupation] [varchar](255) NOT NULL,
[Income] [varchar](25) NOT NULL,
[WPhone] [varchar](12) NOT NULL,
CONSTRAINT [PK__Employme__C190170BC7827524] PRIMARY KEY CLUSTERED
(
You need to do something like this:
DECLARE #NewID INT
INSERT INTO Customer(LastName,FirstName,......) VALUES(Value1, Value2, .....)
SELECT #NewID = SCOPE_IDENTITY()
INSERT INTO Employment(CID,Employer,.....) VALUES(#NewID, ValueA,..........)
SCOPE_IDENTITY: Returns the last identity value inserted into an identity column in the same scope. A scope is a module: a stored procedure, trigger, function, or batch. Therefore, two statements are in the same scope if they are in the same stored procedure, function, or batch.

Get value from other foreign key table based on current table value

I am working on a project where I need to extract the data from excel sheet to SQL Server
, well that bit have done successfully. Now my problem is that for a particular column
called product size, I want to update current table based on product size in other table, I am really very confused , please help me out
Please find the table structure
CREATE TABLE [dbo].[T_Product](
[ProductID] [int] IDENTITY(1,1) NOT NULL,
[PartNo] [nvarchar](255) NULL,
[CategoryID] [int] NULL,
[MaterialID] [float] NULL,
[WireformID] [float] NULL,
[ProductName] [nvarchar](50) NULL,
[ProductSize] [nvarchar](50) NULL,
[ProductLength] [varchar](20) NULL,
[ProductActive] [bit] NULL,
[ProductImage] [varchar](60) NULL
) ON [PRIMARY]
CREATE TABLE [dbo].[T_ProductSize](
[Code] [int] IDENTITY(1,1) NOT NULL,
[ProductSize] [nvarchar](50) NULL,
[Length] [nchar](20) NULL
) ON [PRIMARY]
GO
OK, so ignore the previous answer, I got the wrong end of the stick!!
You want something like this I think:
UPDATE T_Product
SET [ProductLength] = ps.[Length]
FROM T_Product p
INNER JOIN T_ProductSize ps
ON p.[ProductSize] = ps.[ProductSize]
That will take the Length value from T_ProductSize and place it in T_Product.ProductLength based on the value of T_Product.ProductSize
You mention a foreign key but you haven't included a definition for it. Is it between the two tables in your example? If so, which columns make the key? Is product size the key? If so, then your question doesn't make a lot of sense as the value will be the same in both tables.
Is it possible that you mean the product size is to be stored in a separate table and not in the T_Product table? In that case then instead of ProductSize in T_Product you will want the code from the T_ProductSize table (can I also suggest that instead of 'code' you call it 'ProductSizeCode' or better yet 'ProductSizeId' or similar? having columns simply called code can be very confusing as you have no simple way of know what table that value is in). Also, you should always create a primary key on each table: You cannot have a foreign key without one. They don't have to be clustered, that will depend upon hwo your search the table, but I am using a clustered PK for this example. That would give you something like this:
CREATE TABLE [dbo].[T_Product](
[ProductID] [int] IDENTITY(1,1) NOT NULL,
[PartNo] [nvarchar](255) NULL,
[CategoryID] [int] NULL,
[MaterialID] [float] NULL,
[WireformID] [float] NULL,
[ProductName] [nvarchar](50) NULL,
[ProductSizeId] [int] NOT NULL,
[ProductLength] [varchar](20) NULL,
[ProductActive] [bit] NULL,
[ProductImage] [varchar](60) NULL
CONSTRAINT [PK_T_Product] PRIMARY KEY CLUSTERED
(
[ProductID] ASC
) ON [PRIMARY]
) ON [PRIMARY]
GO
CREATE TABLE [dbo].[T_ProductSize](
[ProductSizeId] [int] IDENTITY(1,1) NOT NULL,
[ProductSize] [nvarchar](50) NULL,
[Length] [nchar](20) NULL
CONSTRAINT [PK_T_ProductSize] PRIMARY KEY CLUSTERED
(
[ProductSizeId] ASC
) ON [PRIMARY]
) ON [PRIMARY]
GO
--Now add your foreign key to T_Product.
ALTER TABLE [T_Product] WITH NOCHECK ADD CONSTRAINT [FK_Product_ProductSize] FOREIGN KEY([ProductSizeId])
REFERENCES [T_ProductSize] ([ProductSizeId])
GO
ALTER TABLE [T_Product] CHECK CONSTRAINT [FK_Product_ProductSize]
GO
Now, to retrieve your product along with the product size use something like this:
SELECT p.[ProductID], p.[PartNo], p.[CategoryID], p.[MaterialID], p.[WireformID], p.[ProductName],
ps.[ProductSize], ps.[Length], p.[ProductLength], p.[ProductActive], p.[ProductImage]
FROM [T_Product] p
INNER JOIN [T_ProductSize] ps
ON ps.[ProductSizeId] = p.[ProductSizeId]
If I have understood you correctly, then this is what I think you're after. If not, then have another go at explaining what it is you need and I'll try again.
Try this...
UPDATE t2
SET t2.ProductLength = t1.Length
FROM dbo.T_ProductSize t1
INNER JOIN dbo.T_Product t2 ON t1.ProductSize = t2.ProductSize
