Please refer that here we are discussing about Sql Server only. There is no function named 'Translate' in Sql Server. 'Translate' function exists in Oracle for translating a single character to some other character.

Replace fucntion in Sql server is used to replace a string as well as character to another string or character. No need to have a seperate function like Transalate in Oracle:

Find below the examples to get the clear idea:

Ex 1: Sql Server replace function similar to Oracle Replace function

Declare @Str varchar(100)

set @Str='India is my country'

print @Str

print replace(@Str,'India','Pakistan')

Result

India is my country

Pakistan is my country

Ex 1: Sql Server replace function similar to Oracle Translate Replace function

Declare @Str varchar(100)

set @Str='Think You'

print @Str

print replace(@Str,'i','a')
Result

Think You

Thank You

Note: Please try to post Sql server questions only here. Ther is a seperate section available for Oracle. If we mix both, it will confuse the people who are specializing their skill in particular area. Thank you.

Though the HAVING clause specifies a condition that is similar to the purpose of a WHERE clause, the two clauses are not interchangeable. Listed below are some differences to help distinguish between the two:

1. The WHERE clause specifies the criteria which individual records must meet to be selcted by a query. It can be used without the GROUP BY clause. The HAVING clause cannot be used without the GROUP BY clause.
2. The WHERE clause selects rows before grouping. The HAVING clause selects rows after grouping.
3. The WHERE clause cannot contain aggregate functions. The HAVING clause can contain aggregate functions.

for Example: if for an "Select" statement we use the "where" clause then the the result based on the "where" condition results and then we can use "group by" clause to arrange in some order, Now if we want to impose the condition on that group then we use "having" clause.

The main reason for using WHERE clause is to select rows that are to be included in the query. For example, assume table Test.Suppose I want the names, account numbers, and balance due of all customers from California and Los Angles. Since STATE is one of the fields in the record format, I can use WHERE to select those customers.

Using the code

Code
span style="color: #ff0000;">'CA', 'LA'

Suppose I want the total amount due from customers by state. In that case, I would need to use the GROUP BY clause to build an aggregate query.

Here are the Binary data types in sql server - bit, binary, varbinary, image. Bit variables store a single bit with a value of 0, 1 or NULL. binary(n) variables store n bytes of fixed-size binary data. They may store a maximum of 8,000 bytes. varbinary(n) variables store variable-length binary data of approximately n bytes. They may store a maximum of 8,000 bytes. image variables store up to 2 gigabytes of data and are commonly used to store any type of data file. Rest of the data types are non-binary

I would use full-text indexing as you are on the latest version. Create and store the html in varbinary(max) column and set its associated file type to ".html" in a file type column. Then enable full-text index, so indexer will parse the data and search only the text content while ignoring the HTML tags. We had been using blob to store the documents, with the new features have come out in the later versions, this seems to be best option. We are in the process of migrating one of the app to use varbinary and to take advantage of the search feature. There is another way of storing using filestrem. Here is a good read-up from MS . FILESTREAM enables SQL Server-based applications to store unstructured data, such as documents and images, on the file system. Applications can leverage the rich streaming APIs and performance of the file system and at the same time maintain transactional consistency between the unstructured data and corresponding structured data http://blogs.msdn.com/b/manisblog/archive/2007/10/21/filestream-data-type-sql-server-2008.aspx Here is another old report from MS back in 2006 explains about using oldway of BLOG http://research.microsoft.com/apps/pubs/default.aspx?id=64525 There are multiple options for you, pick the best approach that matches your needs Thanks, Suji

Here are multiple ways to get the table information. The DESCRIBE command does not exist in MS SQL SERVER. This is an Oracle command used to describe the structure of objects within a given database. To achieve the same task in MSSQL Server, there are a series of stored procedures with the prefix SP_ that can be used. To view the structure of a table within the current database, use the command

Code
sp_help 'TABLE_NAME';

If you would like to see more details, Create your custom procedure

Code
span style="color: #ff0000;">'order'

Here is another alternative way to get the same information

Code
span style="color: #ff0000;">'TableName''Employee'

Here is the usage :

Code
span style="color: #ff0000;">'Department''sa''TableName'

Can i update views in SQL if yes in what scenarios?
if your view is joining multiple tables

Ayushi

We can update simple views(having data from one table) and complex views(having data from multiple tables) but columns should be taken from one base table for update.

Normalizatiopn is the process of splitting tables up to reduce record redundancy. For instance if you have a table of addresses you may want to create a table of cities and link the addresses to the cities table in a foreign key. Since the city names would be identical on several records this would save a lot of space. In some cases if tables are not normalized the amount of space they would take up would be so large that it would not be possible to record the data. The amount of normalization that you choose would depend upon how often field data is repeated throughout the table.
