Using LEN within VarChar in a CAST statement - tsql

I'm setting up an Audit Case statement and want to capture the LEN of the field contents in the VarChar() - TSQL doesn't seem to like me doing it that way, does anyone have a simple solution for this - thanks in advance!
Ex: VarChar(Len(a.areacode))
Using MS-SQL 2016
CASE WHEN LEN(a.areacode) > 3 THEN CAST(a.areacode as VarChar(Len(a.areacode)))
ELSE CAST(LEFT(a.areacode,3) as VarChar(3))
END AS areacode

I need to change the output of a query so that instead of it coming back as the abbreviation 'em' it says 'employee'. Tsql

I have the correct result coming back. I just need to convert 6 abbreviations in that result to their correct names. There are 20k names assigned to 1 of 6 abbreviated names.
I tried aliasing but that seems to only work for table names.
I tried doing a case statement but that didn't work.
You need to provide more details (like some sample input and output), but if you have data like EM100, and you want to make it EMPLOYEE 100, then you could use an expression such as:
CASE WHEN ColumnName like 'EM%' THEN 'EMPLOYEE ' + SUBSTRING (ColumnName,3,100)
WHEN ColumnName like 'RN%' THEN 'REGNURSE' + SUBSTRING (ColumnName,3,100)
else ColumnName END
But providing more details will help provide a more specific answer.

Crystal Reports Formula: Help forming IIF Statement

I am working with Crystal Reports 11.5.10.1263 [CR Developer Type: Full].
I am familiar with Programming and SQL syntax in general and have worked with expressions in SSRS & MS Access but never in Crystal Reports.
Problem:
I modified the SQL in the Crystal report and it has had the desired effect - except in the last part of the report output - where the changes I made to the SQL do not have the desired effect.
The 'desired effect' is that when a field named 'FundNumber' has the values '2595', '2597' Then the field named 'Organization' should be assigned the value '41600'.
The Detail Record in the Report has the following three rows as part of its 'Formula':
+ IIf({Data.Payments} > 0, "+01W ", "-01W ")
+ Left({Data.FundNumber}+ SPACE(6),6)
+ Left({Data.Organization}+ SPACE(6),6)
I want to change the Data.Organization row to an IIF Statement that says [pseucode]:
IIf Data.FundNumber IN ["2595", "2597"] Then "41600" Else Data.Organization
I believe the Left() function is saying 'return the left 6 characters of [Data.Organization + 6 Spaces] ?? and that it has to do with the way the data is presented in the output.
I would appreciate help with creating the IIF statement for this.
I included the 'IIf({Data.Payments} ...' row in case that helps - as my google searches have turned up examples that use IF instead of IIF.
Thanks!
The syntax most of the time is the same as VB. Try
IIF({Data.FundNumber} = "2595" or {Data.FundNumber} = "2597", "41600", {Data.Organization})

How to prevent the NULLS being removed?

I am currently using SQL Server 2008R2.
I am using this script:
SELECT a.productname, a.orderdate, a.workarea
FROM database1table1 AS a
WHERE a.orderdate >='2016/08/01'
Which gives the output:
PRODUCT NAME ORDER DATE WORKAREA
x 2016/08/07 NULL
y 2016/08/09 HOLDING
z 2016/08/10 ACTION
a 2016/08/12 ACTION
My problem arises when I amend the above script to read,
...
WHERE a.orderdate >='2016/08/01'
**AND a.workarea NOT IN ('HOLDING')**
When I do this, not only does it remove 'HOLDING', but it also removes the NULL rows as well, which I definitely do not want.
Please can you suggest an amendment to the script to prevent the NULLS being removed - I only want to see the value 'HOLDING' taken out.
With many thanks!
You can try a workaround
AND ISNULL(a.workarea,'') NOT IN ('HOLDING')
It will transform all null a.workarea in the "where" the "not in" works correctly

T-SQL Conversion failed when converting the nvarchar value '12-02' to data type int

I'm trying to convert this NVARCHAR value into a periodeId.
The Raw data could be '12-02'.
My solution for this was first to try this
(1000+CONVERT(INT,LEFT(2,T1.PERIOD_NAME)))*100+CONVERT(Int,RIGHT(2,t1.PERIOD_NAME))
But i get the same error message here and could find any quick solution for it.
I also tried to just do a simple
LEFT(2,T1.PERIOD_NAME) to see if it was the formula itself that crashed it, but the same error came up.
If you want '12-02' to be 1202, then use replace() to remove the hyphen before conversion:
select cast(replace(period_name, '-', '') as int)
In SQL Server 2012+, you should use try_convert(), in case there are other unexpected values.
You can try:
SELECT (1000+CONVERT(INT,LEFT(t1.PERIOD_NAME,2)))*100+CONVERT(Int,RIGHT(t1.PERIOD_NAME,2))
The character_expression that LEFT operates on is at first place, whereas the integer expression that specifies how many characters of the character_expression will be returned, comes at second place.

T-SQL SELECT Statment to Exclude Text Between ( And ) Without Update or Variables

I'm wondering if this is possible, I have a messy set of first name data to work with, and it's shared by other applications so I don't want to run any update statements. But the data will sometime include an AKA such as:
Robert (AKA Bob)
And I am trying to get a clean data where it just says "Robert".
One way I thought of is to use a temp table then CHARINDEX for ( and ) then REPLACE what's between ( and ). This seems like a long winded way to do this.
Is there a smarter way?
EDIT: More examples of the data hell. Sometimes the parenthesis comes in the front or mixed up such as:
(Bill) William
Richard (Dick) Jr.
Untested:
FirstName = case when charindex('(AKA', FirstName) = 0
then FirstName
else substring(FirstName, 1, charindex('(AKA', FirstName)) end
If the noisy string pattern is unpredictable, better to use SQL CLR TVF(table value function), utilize C# code regex. Taking an xml as input parameter, which includes data you need to process, return a table with data processed.
Pieter got the ball rolling for me! Thank you for getting me started on the right track!
SELECT
CASE WHEN FirstName like '%)%'
THEN REPLACE(FirstName,
SUBSTRING(FirstName,CHARINDEX('(',FirstName),CHARINDEX(')',FirstName)-CHARINDEX('(',FirstName)+1),'')
ELSE FirstName END
