How do I get list of all tables in a database using TSQL?

I am using SQL Server 2014 and want to get all the tables name in a particular database STUDENT through a SQL query.
How is it possible?
Thanks
You want to query sys.objects and look for everything with the type description 'USER_TABLE'. You could use a query like this;
SELECT
*
FROM STUDENT.sys.objects
WHERE type_desc = 'USER_TABLE'
The FROM clause has the usual format: DatabaseName.SchemaName.TableName.
Or as marc_s mentions, you can use sys.tables instead;
SELECT
*
FROM STUDENT.sys.tables

How to create a table from select query result in SQL Server 2008 [duplicate]

I am trying to create a new table in Microsoft SQL Server Management Studio based on two existing tables.
When I execute the query below, I get an error saying that there is an:
Incorrect syntax near the keyword 'SELECT'.
SQL code:
CREATE TABLE NEW_TABLE AS
SELECT OLD_TABLE.A
, OLD_TABLE.B
, OTHER_OLD_TABLE.C
FROM OLD_TABLE
INNER JOIN OTHER_OLD_TABLE
ON OLD_TABLE.A = OTHER_OLD_TABLE.D;
I looked at various other problems, but could not find a solution to mine. Do you have any idea what could be wrong with the syntax?
Alternatively, you can use SELECT * INTO new_table statement just like this.
SELECT OLD_TABLE.A
, OLD_TABLE.B
, OTHER_OLD_TABLE.C INTO NEW_TABLE
FROM OLD_TABLE
INNER JOIN OTHER_OLD_TABLE
ON OLD_TABLE.A = OTHER_OLD_TABLE.D;
this statement will also create a new table as you required.

SQL Server Escape an Underscore

How do I escape _ in SQL Server? [duplicate]
(3 answers)
Closed 7 years ago.
I need to find a list of all items starting with an underscore: _
The obvious doesn't work:
select * from role where Name like '_%'
This still returns all items.
The following also returns all items.
select * from role where Name like '\_%'
select * from role where Name like '__%'
anyone knows how to escape a underscore? or how else I can achieve this StartWithUnderscore functionality?
I found the answer:
select * from role where Name like '[_]%';
You can escape with any character you want eg
select * from role where Name like '!_%' ESCAPE'!'

MySQL LIMIT clause equivalent for SQL SERVER
(5 answers)
Closed 9 years ago.
I am trying to use LIMIT into SQL server 2008 but its not working, what can I do, I am new to SQL I have used mySQL before.
Here is the SQL query I am trying:
SELECT * FROM konto WHERE id_e_klientit = 9 ORDER BY koha_relizimit DESC LIMIT 1
Try SELECT TOP 1 * ...
Also see http://www.w3schools.com/sql/sql_top.asp for more details.
In MSSQL it's apparently something like SELECT TOP x * FROM ...
SELECT TOP 1 * FROM konto WHERE id_e_klientit = 9 ORDER BY koha_relizimit DESC
