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

There is a function in SQL server - TRIM
For example TRIM(',' FROM #str)
Documentation says - TRIM removes the space character char(32) or other specified characters from the start and end of a string.
But how does this function implemented in terms of sql? Why does FROM allowed there?
Official docs says that
In Transact-SQL, the FROM clause is available on the following statements:
DELETE
UPDATE
SELECT.
But I don't see select, update or delete here. How does it works? How can I implement similar function? Where is documentation for this feature at all?
This use of FROM has nothing to do with the FROM clause in a SELECT (or UPDATE or DELETE) statement.
It is simply the syntax for this particular function call. I think this form of the function is specified by the SQL standard.
Another case of such ambiguity -- that I can readily think of -- is GROUPING which is used for both GROUPING SETS and as a special function. There are probably others as well.
Is there any other way to replace multiple strings in sql server 2008r2? which is also fast?
My query is below.
Select REPLACE(REPLACE(EmailText,'#{Name}#',UV.Name),'#{organisation}#',CV.Organisation)
I am written it with example also
Select REPLACE(REPLACE('Hi #{Name}# from #{organisation}#','#{Name}#','Jhon'),'#{organisation}#','Cocacola')
There are all sorts of ways:
A CLR function equivalent to string.Format in C#
String.Format like functionality in T-SQL?
But 'best' as in 'fastest' is probably going to be using REPLACE Repeatedly, as all the attempts in these links have some limitation..
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).
I'm trying to filter results from a Query i have created in Microsoft Query to pull data from a database into my Excel sheet. Specifically I'm trying to filter out based on the nth character of a string.
I can easily filter out the based on the first char:
SOPOrderReturnLine.ItemCode Like 'A25%'
But I have no idea how I could filter to show only entries where the 10th char = "A". I'm sure I have to use a Substring function, but it's not familiar to me and I'm struggling to get it to work.
Try to edit your sql query and enter the following statement:
select * from SOPOrderReturnLine where substring(SOPOrderReturnLine.ItemCode,10,1) = 'A';
The statement should work for a MySql database as well as for an Sql Server in the background; (I've tested it with an MySql database).
Hope this helps.
In MSQuery (Jet under the covers, I think), the function is Mid.
SELECT * FROM tblLocation WHERE (Mid(LocationName,2,1)='e')
to find a lower case 'e' in the second location.
I assume when you say MS Query, you are running a query against a DBMS (SQL Server or some other via ODBC).
The use of substr, substring or mid should work, depending on which DBMS. That said, unless you're using MS Access, I think most DBMSs will support the underscore character as "any single character." It might even work in Access, but I don't know for sure. Therefore, I think in addition to the suggestions you've gotten, this will also work in most cases:
SOPOrderReturnLine.ItemCode Like '_________A%'
If you want to use substring, don't hold me to these, but I think:
Oracle / DB2 / SQLite - substr
Microsoft SQL Server / Sybase / MySQL - substring
MS Access - mid
PostgreSQL -substr or substring
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
http://msdn.microsoft.com/en-us/library/ms181984.aspx
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).
