How to replace all string in SQL Server 2005? - sql

In postgresql database have one function btrim(string text [, characters text]).
For examples
btrim('xwxpostsqlwwx', 'wx')
In this function return value postsql.
Like this I need to do in SQL Server 2005. Is there any similar builtin function available in SQL Server?


REPLACE, SUBSTRING,CHARINDEX

I don't know of any exact equivalent, but you should be able to achieve the same results using SQLServer's Regular Expression functionality.


I believe there is no such a built-in function, but you can create your own if you like. You can find an example of a function doing exactly what you want here (at the bottom of the page).

How to create real function in Bigquery Legacy SQL

I know UDF in legacy sql, but UDF need you pass whole row into function, and return whole record, and UDF can't put into select section, this is not real function I need, Is Bigquery Legacy SQL can write function like Standard SQL? (can put into select or where section)
thanks :)

This functionality is only supported in Standard SQL (and as Elliott mentions in the comments, is unlikely to be added to Legacy SQL because it is being phased out).

Informatica Coding to SQL

I am attempting to translate the following Informatica code to the equivalent SQL scripts. I am a little stuck as I am not familiar with Informatica and would appreciate any assistance.
The original informatica code reads as follows:
LTRIM(RTRIM(SUBSTR(COV_REINS_CONCAT_BK,11, INSTR(COV_REINS_CONCAT_BK, '|',1,3)-INSTR(COV_REINS_CONCAT_BK, '|',1,2)-1 ))) || 'C'

select LTRIM(RTRIM(SUBSTR(COV_REINS_CONCAT_BK,11,INSTR(COV_REINS_CONCAT_BK,'|',1‌​,3)
-INSTR(COV_REINS_CONCAT_BK,'|',1,2)-1 )))||'C' from TABLE;
Above script will work fine in Oracle. Please replace table with your table name.

It becomes increasingly difficult to port such expressions that make extensive use of INSTR function using the occurrence parameter.
Maybe it's easier to create in your MS-SQL database an INSTR equivalent function that supports the occurrence parameter. See how to create the dbo.INSTR function here.
On this same site you can also see a table with more function equivalences from Oracle to MS-SQL.
Then the expression from the comment becomes much easier to translate:
LTRIM(RTRIM(SUBSTRING(COV_REINS_CONCAT_BK,11,dbo.INSTR(COV_REINS_CONCAT_BK,'|',1‌​,3)
-dbo.INSTR(COV_REINS_CONCAT_BK,'|',1,2)-1 )))+'C'
Here SUBSTR became SUBSTRING, and INSTR became dbo.INSTR and concatenation || was changed to +.

The SUBSTR() and instr() functions are from the Informatica Transformation Language. IMHO it has its roots in function names from Oracle and MSSQL / Sybase function names. This is why it doesn't translate directly to either but is similar. The functions are very well documented in the online help. You'll need to review the switches in the INSTR() function for case sensitivity and the like to ensure their parallel can be written correctly in another tool. The numbers may translate to different things and in some of the Informatica functions the end arguments can be omitted such as, in the SUBSTR() function, meaning that the SUBSTR() will take effect from the numbered position to the end of the string regardless of length. The typing of the port in Informatica can affect the result too, although in this case, the combined function is performing a trim at the end.

SUBSTR() and INSTR() functions are not MS SQL Server functions. I'm guessing the code snippet is Oracle's PL/SQL. Try resources such as http://www.dba-oracle.com/oracle_news/2005_12_16_sql_syntax_differences.htm

Any function equivalent to oracle sql's DBMS_UTILITY.get_hash_value() in Transact-SQL?

On searching msdn, I found a built-in function called HASHBYTES(). Not sure if that can be used to get a result that DBMS_UTILITY.get_hash_value() gives in oracle.I am using SQL Server 2008. Thanks in advance.

HASHBYTES is close, but uses presets for certain algorithms (e.g. SHA1 or MD5)
You can't choose the base or length like you can with DBMS_UTILITY.GET_HASH_VALUE()
You may have to roll your own to emulate it exactly but I'd see this as a backwards step...

How can i search a non case sensitive word with Sql Server XQuery?

I'm using an Xml field in my Sql Server database table. I'm trying to search a word using the XQuery contains method but it seems to search only in case sensitive mode. The lower method isn't implemented on Sql Server XQuery implementation also.
¿Is there a simple solution to this problem?

If you're using SQL Server 2005, I'm afraid you're out of luck.
If you're using SQL Server 2008, you can use the upper-case function like this :
DECLARE #x xml = N'abcDEF!#4';
SELECT #x.value('fn:upper-case(/text()[1])', 'nvarchar(10)');
Here's a link on MSDN for the upper-case syntax and a couple search examples :

First link from google points to MSDN page:
contains Function (XQuery)
In order to get case-insensitive
comparisons, the upper-case or
lower-case functions can be used.
