I want to create a table named Domains in HSQL. But when i try to do so it includes 29 columns although my table definition specifies just 5.There is a Domains System View and it seems it is including these columns also in my metadata.Because of this i am not able to insert anything in my db as those unwanted columns from Domains System View also contain some non-null values.
I tried creating schema but it is not what i need as my solution.
I need to override this Domains System View or stop the metadata from picking it.
Does anyone know how can we do it?
I am stuck at it for more than few days now.
CREATE TABLE IF NOT EXISTS Domains
(
domain_id INTEGER NOT NULL,
name VARCHAR(100) NOT NULL,
description VARCHAR(500) NOT NULL,
CREATED_BY VARCHAR(8) NOT NULL,
LAST_UPDATED_BY VARCHAR(8) NOT NULL,
PRIMARY KEY (domain_id)
);

I'm new to the MS SQL server. Our client has given us a SQL server DB and for this DB they have configured the Service Principal Authentication. So I logged into the DB using my client company account and then I tried to create a table without giving any schema name. for example
CREATE TABLE visits (
visit_id INT PRIMARY KEY IDENTITY (1, 1),
first_name VARCHAR (50) NOT NULL,
last_name VARCHAR (50) NOT NULL,
visited_at DATETIME,
phone VARCHAR(20),
store_id INT NOT NULL,
);
so when I ran this query it gave me the below error
Msg 2760, Level 16, State 1, Line 1
The specified schema name "aashay.amballi#<company>.com" either does not exist or you do not have permission to use it.
so now when I created the table with DBO schema it created the table.
CREATE TABLE dbo.visits (
visit_id INT PRIMARY KEY IDENTITY (1, 1),
first_name VARCHAR (50) NOT NULL,
last_name VARCHAR (50) NOT NULL,
visited_at DATETIME,
phone VARCHAR(20),
store_id INT NOT NULL,
);
So now when I tried to query this visits table without any schema (i.e. DBO) select * from visits it actually gave me the result.
Also when I ran the select SCHEMA_NAME() to check what is the default schema, it returned null. So is there a possibility that when there is no default schema that is set for a user and while creating a table without a schema name it will give that error? if that is the case then while querying without any schema how it's picking the dbo schema by default?
So I'm a bit confused about how this is working. Can anyone please explain this?
This question is regarding the question that I asked a couple of days back when I'm trying to integrate MSSQL with service principal authentication with the Django Framework - Django MigrationSchemaMissing exception on Azure SQL using service principal auth
From the CREATE TABLE description:
If type_schema_name isn't specified, the SQL Server Database Engine
references type_name in the following order:
The SQL Server system data type.
The default schema of the current user in the current database.
The dbo schema in the current database.
And what is your default schema? It depends on options of CREATE USER statement used when creating your user's account:
WITH DEFAULT_SCHEMA = schema_name Specifies the first schema that will
be searched by the server when it resolves the names of objects for
this database user.
You can skip the schema in queries, but it is a best practise to always use schemas.
I wasn't sure how I should name the Question. I try to explanin what I need to achieve.
I will get a list from our Customer where the installed software on each machin will be listed.
Example_
Machines List
Hostname SW
PC001 SW001
PC001 SW002
PC002 SW003
PC002 SW001
PC003 SW003
Software List
SW Name Status
SW001 not okay
SW002 not okay
SW003 ready
I need to have an SQL or MS-Access logik to find all Hostname which have only SW installed with Status okay
and - in adition - i need a logic to tell me what kind of SW product need to be okay to make additional Hostnames availabale with only okay Software installed.
At the moment i struggle with this question
rgds
Sebastian
At the moment i am not sure how to select the multiple rows one Hostname could have as the whole - so If i use a select statement i get all Hostname where the specified product is installed - but other installed products aren't reflected.
Well i could help you a bit, but you have to do something by yourself,
So first of all i modified your DDL code first
CREATE TABLE `machines` (
`id` int(11) NOT NULL,
`hostnames` varchar(20) NOT NULL,
`id_soft` int(11) NOT NULL
)
CREATE TABLE `software` (
`id_soft` int(11) NOT NULL,
`software_name` varchar(20) NOT NULL,
`status` varchar(20) NOT NULL
)
--
-- Indexes for table machines
ALTER TABLE `machines`
ADD PRIMARY KEY (`id`),
ADD KEY `id_soft` (`id_soft`);
--
-- Indexes for table software
ALTER TABLE `software`
ADD PRIMARY KEY (`id_soft`);
--
-- Constraints for table machines
ALTER TABLE `machines`
ADD CONSTRAINT `machines_ibfk_1` FOREIGN KEY (`id_soft`) REFERENCES
`software` (`id_soft`);
and here is your query for showing hostnames only where the status is okey or ready!
SELECT hostnames
FROM machines
LEFT JOIN software on machines.id_soft = software.id_soft
WHERE machines.id_soft = (SELECT software.id_soft from software
WHERE software.status like 'ready');
So this will definitely help you but you have to do other things alone, and only if you cant find a solution, we will be here to get help you.
I'm new to SQL Server and Entity Framework.
Suppose I have 2 tables named tblOfficeAccessType and tblOfficeAccessDepartment. I introduce them in this picture.
I put some data in tables as instance. In tblOfficeAccessType we have the access codes to office and in tblOfficeAccessDepartment we have various departments of office. we want that the User could define various access levels for each AccessCode. For example The User could define the [AccessCode = AQ1] allows to access to the Manager_Room but It does not allow to access to the Store. Note that various offices have various departments and various Users have Various selections. How do that?
CREATE TABLE [dbo].[tblOfficeAccessDepartment]
(
[DepartmentId] VARCHAR (10) NOT NULL,
[DepartmentName] VARCHAR (50) NOT NULL,
PRIMARY KEY CLUSTERED ([DepartmentId] ASC)
);
CREATE TABLE [dbo].[tblOfficeAccessType]
(
[AccessId] VARCHAR (10) NOT NULL,
[AccessCode] VARCHAR (50) NOT NULL,
PRIMARY KEY CLUSTERED ([AccessId] ASC)
);
Update :
I want something like this
I have a slight problem!
I have an original base table "StaffAddressDetails":
CREATE TABLE StaffAddressDetails
(ContactID INTEGER NOT NULL,
Postcode VARCHAR (10) NOT NULL,
HouseNameOrNumber VARCHAR (50) NOT NULL,
Street VARCHAR (50) NOT NULL,
Street2 VARCHAR (50) DEFAULT '...',
Town VARCHAR (50) NOT NULL,
County VARCHAR (50) NOT NULL,
Country VARCHAR (50) NOT NULL,
StaffID INTEGER NOT NULL,
CONSTRAINT StaffAddressDetails_PK PRIMARY KEY (ContactID, Postcode),
CONSTRAINT StaADContactIDSCD FOREIGN KEY (ContactID)
REFERENCES StaffContactDetails (ContactID));
I want the members of staff to be able to see only their own details, so I have a created a view "HDPBHTTSKStaffAddDetsForSelf" and granted that view to a role "Teacher":
CREATE VIEW HDPBHTTSKStaffAddDetsForSelf AS
SELECT * FROM StaffAddressDetails
WHERE StaffID IN
(SELECT USER
FROM DUAL);
...and...
GRANT SELECT, INSERT, UPDATE ON HDPBHTTSKStaffAddDetsForSelf TO Teacher;
That all works fine - the problem comes when inserting a new row (when logged in on a teacher's account) should, say, the teacher acquire a new address and wish to add it to the school system.
The inserted row appears when queried from that teacher's account, but does not pass down to the original base table, meaning no-one except the teacher can see it, not even admin.
Is there a quick fix??
Many thanks in advance,
Zulu
You should use the WITH CHECK OPTION when creating your view, so that Teacher role members cannot insert or update data with different StaffID than their own, i.e.
create view ... as select ... from ... where ... WITH CHECK OPTION;
Further, agreeing with #danihp, only reason I see why data seem not being passed down to the table for the admin to see, is that inserting transaction is not being committed.
According to my "Pro Oracle Database 11g Administration" book:
If you don't want a user to be able to perform INSERT, UPDATE, or
DELETE operations on a view, then don't grant those object privileges
on the underlying table(s) to that user.
Of course, you want to allow DML operations to the underlying table. To me, that says you also need to make sure that the "Teacher" has appropriate permissions on the StaffAddressDetails table, as well.
GRANT SELECT, INSERT, UPDATE ON StaffAddressDetails TO Teacher;
And to echo Carl's answer, it's a good idea to create this type of view using WITH CHECK OPTION.
I have some txt files that contain tables with a mix of different records on them which have diferent types of values and definitons for columns. I was thinking of importing it into a table and running a query to separate the different record types since a identifier to this is listed in the first column. Is there a way to change the value type of a column in a query? since it will be a pain to treat all of them as text. If you have any other suggestions on how to solve this please let me know as well.
Here is an example of tables for 2 record types provided by the website where I got the data from
create table dbo.PUBACC_A2
(
Record_Type char(2) null,
unique_system_identifier numeric(9,0) not null,
ULS_File_Number char(14) null,
EBF_Number varchar(30) null,
spectrum_manager_leasing char(1) null,
defacto_transfer_leasing char(1) null,
new_spectrum_leasing char(1) null,
spectrum_subleasing char(1) null,
xfer_control_lessee char(1) null,
revision_spectrum_lease char(1) null,
assignment_spectrum_lease char(1) null,
pfr_status char(1) null
)
go
create table dbo.PUBACC_AC
(
record_type char(2) null,
unique_system_identifier numeric(9,0) not null,
uls_file_number char(14) null,
ebf_number varchar(30) null,
call_sign char(10) null,
aircraft_count int null,
type_of_carrier char(1) null,
portable_indicator char(1) null,
fleet_indicator char(1) null,
n_number char(10) null
)
Yes, you can do what you want. In ms access you can use any VBA functions and with some
IIF(FirstColumn="value1", CDate(SecondColumn), NULL) as DateValue,
IIF(FirstColumn="value2", CDec(SecondColumn), NULL) as DecimalValue,
IIF(FirstColumn="value3", CStr(SecondColumn), NULL) as StringValue
You can use all/any of the above in your SELECT.
EDIT:
From your comments it seems that you want to split them into different tables - importing as text should not be a problem in that case.
a)
After you import and get it in the initial table, create the proper table manually setting you can INSERT into the proper table.
b)
You could even do a make table query, but it might be faster to create it manually. If you do a make table query you have to be sure that you have casted the data into proper type in your select.
EDIT2:
As you updated the question showing the structure it becomes obvious that my suggestion above will not help directly.
If this is one time process you can follow HLGEM's solution. Here are some more details.
1) Import into a table with two columns - RecordType char(2), Rest memo
2) Now you can split the data (make two queries that select based on RecordType) and re-export the data (to be able to use access' import wizard)
3) Now you have two text files with proper structure which can be easily imported
I did this in my last job. You start with a staging table that has one column or two coulmns if your identifier is always the same length.
Then using the record identifier, you move the data to another set of staging tables, one for each type of record you have. This will be in columns for the data and can have the correct data types. Then you do any data cleaning you need to do. Then you insert into the real production table.
If you have a column defined as text, because it has both alphas and numbers, you'll only be able to query it as if it were text. Once you've separated out the different "types" of data into their own tables, you should be able to change the schema definition. Please comment here if I'm misunderstanding what you're trying to do.
