SQL Server - SELECT FROM stored procedure. SQL Server: CREATE LOGIN statement. How to: Create and Run a CLR SQL Server Stored Procedure. Create SQL stored procedures by adding Stored Procedure items to SQL Server projects. After you successfully deploy to a computer running SQL Server, stored procedures created in managed code are called and executed like any other stored procedures.

To create a SQL Server stored procedure Add code to execute and test your stored procedure to the Test.sql (debug.sql in Visual C++) file in the TestScripts folder in your project. For example, if you deployed a stored procedure, run it by calling EXEC <StoredProcedureName> and passing in any expected parameters.

If your stored procedure does not return any values, insert additional code to verify data was affected by the stored procedure. EXEC InsertCurrency 'AAA', 'Currency Test' SELECT * from Sales.Currency where CurrencyCode = 'AAA' Tasks Concepts Reference Other Resources. Enabling CLR Integration.

Find Last Restart of SQL Server. Changing a Database's Collation | Database Performance Tuning content from SQL Server Pro. With SQL Server, you can easily change the collation of a database. Before you do so, though, you should be familiar with the purpose and structure of collations, know what will be altered when the collation changes, and understand the consequences if a collation change isn't done correctly. It's also a good idea to have a methodology for changing the collation of a SQL Server database. I use a seven-step process, which I'll share with you. Related: Forcing Collation in the WHERE Clause The Purpose and Structure of Collations Collation serves two important roles: It defines the rules that SQL Server applies when sorting and comparing characters in a database. Let's take a close look at each of these roles. Defining the sort and comparison rules.

SQL Server collations, which start with the prefix SQL_. Defining the underlying code pages. There are 8 bits in a byte, and the 8 bits can be turned ON and OFF in 256 different patterns. Related: 7 Considerations for Server Consolidations Case 1. Trigger - Get values from updated. Hi, Jarhead104, There are only two virtual tables you can workwith inside a trigger, those are "INSERTED" and "DELETED". The data will vary inside these virtual tables depends on the DML operation we performed, such as: Insert Operation: When you try to insert a record "INSERTED" virtual table contains the newly inserted record, where as "DELETED" virtual remains empty. Update Operation: When you try to update any record, first the old record will be placed into the "DELETED" virtual table and the newly updated record is hold by the "INSERTED" virtual table. That means you can get the old value from "DELETED" and the currently updating value through "INSERTED" virtual table. you can query them like: -- To get the old record value -- To get the updated value Delete Operation: When try to delete any particular record the deleted record will be inserted into the "DELETED" virtual table. 1. 2.

DECLARE @OldValue int, @NewValue int SELECT @OldValue = Column1 FROM DELETED Hope it helps. Sp_addlinkedsrvlogin (Transact-SQL) Creates or updates a mapping between a login on the local instance of SQL Server and a security account on a remote server. Transact-SQL Syntax Conventions sp_addlinkedsrvlogin [ @rmtsrvname = ] 'rmtsrvname' [ , [ @useself = ] 'TRUE' | 'FALSE' | NULL ] [ , [ @locallogin = ] 'locallogin' ] [ , [ @rmtuser = ] 'rmtuser' ] [ , [ @rmtpassword = ] 'rmtpassword' ] [ @rmtsrvname = ] 'rmtsrvname' Is the name of a linked server that the login mapping applies to. rmtsrvname is sysname, with no default. [ @useself = ] 'TRUE' | 'FALSE' | 'NULL' Determines whether to connect to rmtsrvname by impersonating local logins or explicitly submitting a login and password. A value of TRUE specifies that logins use their own credentials to connect to rmtsrvname, with the rmtuser and rmtpassword arguments being ignored.

. [ @locallogin = ] 'locallogin' Is a login on the local server. locallogin is sysname, with a default of NULL. . [ @rmtuser = ] 'rmtuser' [ @rmtpassword = ] 'rmtpassword' 0 (success) or 1 (failure) A. Or. Sp_addlinkedserver (Transact-SQL) Creates a linked server. A linked server allows for access to distributed, heterogeneous queries against OLE DB data sources.

After a linked server is created by using sp_addlinkedserver, distributed queries can be run against this server. If the linked server is defined as an instance of SQL Server, remote stored procedures can be executed. Transact-SQL Syntax Conventions sp_addlinkedserver [ @server= ] 'server' [ , [ @srvproduct= ] 'product_name' ] [ , [ @provider= ] 'provider_name' ] [ , [ @datasrc= ] 'data_source' ] [ , [ @location= ] 'location' ] [ , [ @provstr= ] 'provider_string' ] [ , [ @catalog= ] 'catalog' ] [ @server= ] 'server' Is the name of the linked server to create. server is sysname, with no default. [ @srvproduct= ] 'product_name' Is the product name of the OLE DB data source to add as a linked server. product_name is nvarchar(128), with a default of NULL.

SQL Server Helper - Frequently Asked Questions - SQL Server Equivalent of Oracle Functions. Oracle's EXTRACT function, which is only available starting from Oracle 9i, extracts and returns the specified component comp of date/time or interval expression dt: EXTRACT ( comp FROM dt The valid components are YEAR, MONTH, DAY, HOUR, MINUTE, SECOND, TIMEZONE_HOUR, TIMEZONE_MINUTE, TIMEZONE_REGION and TIMEZONE_ABBR. The specified component must exist in the expression.

So, to extract a TIMEZONE_HOUR, the date/time expression must be a TIMESTAMP WITH TIMEZONE data type. The equivalent of Oracle's EXTRACT function in SQL Server is the DATEPART date function. The DATEPART function accepts two arguments and returns an integer representing the specified date part of the specified date: DATEPART ( datepart, date ) datepart is the parameter that specifies the part of the date to return. Date is an expression that returns a datetime or smalldatetime value, or a character string in a date format. C# - What size do you use for varchar(MAX) in your parameter declaration?

Stored Procedures: Returning Data. By Bill Graziano on 9 April 2001 | 9 Comments | Tags: Stored Procedures This article discusses three common ways to return data from stored procedures: returning result sets (SELECT statements), using output variables and using the RETURN statement. Each example includes client-side code (ASP.NET) and server-side code (T-SQL) to read the results. (This article has been updated through SQL Server 2005.) All the examples in this article use the AdventureWorks database and have been tested through SQL Server 2008. All the client code examples are written using ASP.NET 2.0. Result Sets Result sets are what you get when you run a simple SELECT statement inside a stored procedure.

CREATE PROCEDURE dbo.GetPeopleByLastName (@LastName NVARCHAR(50)) ASSELECT ContactID, FirstName, LastName FROM Person.Contact WHERE LastName = @LastName ORDER BY ContactID If you just execute this stored procedure in SQL Server Management Studio you get a result set that looks like this: using System.Data.SqlClient; Sys.all_objects (Transact-SQL) Stored Procedures: Returning Data. Hash - SQL Server 2008 and HashBytes. Sql - Converting strings longer than 8000 characters to Varbinary(MAX) Tsql - Using VARCHAR(MAX) with string concatenation in SQL Server 2005. SQL Server 2008 R2 Varbinary Max Size. FILESTREAM Overview. Much data is unstructured, such as text documents, images, and videos. This unstructured data is often stored outside the database, separate from its structured data. This separation can cause data management complexities. Or, if the data is associated with structured storage, the file streaming capabilities and performance can be limited.

FILESTREAM integrates the SQL Server Database Engine with an NTFS file system by storing varbinary(max) binary large object (BLOB) data as files on the file system. FILESTREAM uses the NT system cache for caching file data. In SQL Server, BLOBs can be standard varbinary(max) data that stores the data in tables, or FILESTREAM varbinary(max) objects that store the data in the file system. Objects that are being stored are, on average, larger than 1 MB.Fast read access is important.You are developing applications that use a middle tier for application logic. FILESTREAM data must be stored in FILESTREAM filegroups. Integrated Security Integrated Management. Sp_helpdb (Transact-SQL)

CONVERT Vs PARSE. PARSE is one of the new built-in conversion function introduced as a Part of Sql Server 2012. PARSE function converts the string expression to the requested data type. It tries it’s best to translate the string value to requested type but if it fails to translate then raises an exception. Important Note: This PARSE function is not a native Sql function, instead it is a .NET Framework Common Language Run-time dependent function. Then obviously it will have the performance overhead and also requires the presence of .NET CLR on the database Server. Continue to use the existing CAST and CONVERT functions wherever it is possible. Syntax: PARSE ( string_value AS data_type [ USING culture ] ) Parameter Details:string_value : String expression which needs to be parsed.data_type : Output data type, e.g.

INT, NUMERIC, DATETIME etc.culture : Optional string that identifies the culture in which string_value is formatted. Now let us understand this PARSE function with examples: Storing Unicode string into VARBINARY (MAX) I came across an interesting issue while working on a client project a couple of days ago. I thought it might be a good idea to share this information.We had to populate a “data” field which is of type “varbinary(max)”, the content of which is picked up by sharepoint to index.We had two types of items Items which have files (these files were directly written to the ‘data’ field in their binary form) Items which didn’t have any files (the ‘data’ field needed to be populated with the title and description of item) There were no issues with files, but when ‘data’ field was populated with title and description, nothing from that field was getting indexed.Both the title and description fields where of type ‘nvarchar(max)’.

Let’s look at what happens when you write data of ‘varchar(max)’ and ‘nvarchar(max)’ into the ‘varbinary(max)’ field. Upon running the above code the following result is returned : Here you can see that the txt file for Binary Unicode field has extra spaces.Problems/Issues. Sql server - Generate MD5 hash string with T-SQL. HASHBYTES (Transact-SQL) HASHBYTES ( '<algorithm>', { @input | 'input' } ) <algorithm>::= MD2 | MD4 | MD5 | SHA | SHA1 | SHA2_256 | SHA2_512 '<algorithm>' Identifies the hashing algorithm to be used to hash the input. This is a required argument with no default.

The single quotation marks are required. @input Specifies a variable containing the data to be hashed. ' input ' Specifies an expression that evaluates to a character or binary string to be hashed. Allowed input values are limited to 8000 bytes. Varbinary (maximum 8000 bytes) Return the hash of a variable The following example returns the SHA1 hash of the nvarchar data stored in variable @HashThis. DECLARE @HashThis nvarchar(4000); SET @HashThis = CONVERT(nvarchar(4000),'dslfdkjLK85kldhnv$n000#knf'); SELECT HASHBYTES('SHA1', @HashThis); Return the hash of a table column The following example returns the SHA1 hash of the values in column c1 in the table Test1. Here is the result set. SQL UNIQUE Constraint. Sp_sequence_get_range (Transact-SQL) SQL Server SEQUENCE Basics. The SEQUENCE statement introduced in SQL Server 2012 brings the ANSI SQL 2003 standard method of generating IDs.

This is a great relief to database professionals as it solves some problems what are awkward to solve with the IDENTITY property. Joe Celko explains the basics of using a SEQUENCE SQL Server now has the ANSI/ISO Standard CREATE SEQUENCE statement. Hooray! The bad news is that most programmers will not be aware of the significance of the underlying math.

A SEQUENCE is not an IDENTITY. Obviously, IDENTITY increments its value from physical insertion to physical insertion; no big jumps, no gaps. We have, for a long time, created a table of integers that has all sorts of uses. Now, let's do math. What is the Difference Between a Sequence and a Series? A sequence is a list of numbers. A series is a sum of numbers. Sequences and series are closely related to each other. Tag Numbers versus Sequence A tag number is string, usually of fixed length, made up of digits. 1. 2. 3. Sql - Optimal way to concatenate/aggregate strings. Deprecated Database Engine Features in SQL Server 2014. Ntext, text, and image (Transact-SQL) The Seven Sins against TSQL Performance. There are seven common antipatterns in TSQL coding that make code perform badly, and three good habits which will generally ensure that your code runs fast.

If you learn nothing else from this list of great advice from Grant, just keep in mind that you should 'write for the optimizer'. It’s not enough that your code is readable: it must perform well too. There are three very basic rules for writing T-SQL that performs. They are cumulative. Write to your data structures: If you are storing a datetime data type, use that, not a varchar or something else. Then, there are some very specific and common mistakes that people make in their T-SQL code. Using the wrong data types This is surprisingly simple in concept, but seems to be incredibly difficult in practice. Don’t believe me? SELECT e.BusinessEntityID, e.NationalIDNumber FROM HumanResources.Employee AS e WHERE e.NationalIDNumber = 112457891; Nice & simple.

That’s right. WHERE e.NationalIDNumber = '112457891'; Use the correct data types. a.City, Nodes() Method (xml Data Type) The nodes() method is useful when you want to shred an xml data type instance into relational data. It allows you to identify nodes that will be mapped into a new row. Every xml data type instance has an implicitly provided context node. For the XML instance stored in a column or variable, this is the document node. The document node is the implicit node at the top of every xml data type instance. The result of the nodes() method is a rowset that contains logical copies of the original XML instances. In these logical copies, the context node of every row instance is set to one of the nodes identified with the query expression, so that subsequent queries can navigate relative to these context nodes.

You can retrieve multiple values from the rowset. Nodes (XQuery) as Table(Column) XQuery Is a string literal, an XQuery expression. Table(Column) Is the table name and the column name for the resulting rowset. As an example, assume that you have the following table: SELECT T2.Loc.query('.')
