IN() function failure - sql

Can somebody please help me to understand why the IN() function does not work in any of the below attempts?
DECLARE #Company VARCHAR(50) = ('''ABC''' + ', ' + '''DEF''' + ', ' + '''VEG''' + ', ' + '''HIJ''') --+ WNY, VEG''')
PRINT #Company
PRINT IIF('VEG' IN (#Company), 'TRUE', 'FALSE');
DECLARE #Company2 VARCHAR(50) = ('''ABC, DEF, VEG, HIJ''')
PRINT #Company2
PRINT IIF('VEG' IN (#Company2), 'TRUE', 'FAL
Tried running the command as presented and both IIF()s return false.

How to convert string which is output of select .....from for JSON AUTO to JSON Formatted file which is readable without using third party tool SSIS

HI I am writing SSIS package to get the output from
Select a,b,c from CUST FOR JSON AUTO
However I am getting output in a single row like
{"a":"Rock" ,"b":"paper" ,"c":"scissors"}, {"a":"Rock" ,"b":"paper" ,"c":"scissors"}, {"a":"Rock" ,"b":"paper" ,"c":"scissors"}....
However I want output as
{
"a":"Rock",
"b":"paper",
"c":"scissors"
},
{
"a":"Rock",
"b":"paper",
"c":"scissors"
},
{
"a":"Rock",
"b":"paper",
"c":"scissors"
},
My client argument is the Json file will be big file and he don't want to do extra formatting and should be readable

If you can add a javascript component to SSIS, it can be done.
(I'm not sure on how to do that in SSIS). But here is how you do it in javascript
I have a way to get this done rather messy way, but you can see whether that serves you the purpose
DECLARE #nl varchar(2) = char(13), #Json nvarchar(MAX) = (Select a,b,c from #CUST FOR JSON AUTO)
Select #Json = Replace(#Json, '[{','[' + #nl + '{' + #nl)
Select #Json = Replace(#Json, '{','{' + #nl)
Select #Json = Replace(#Json, '","','",' + #nl + '"' )
Select #Json = Replace(#Json, '"},{','"' + #nl + '},' + #nl + #nl + '{' )
Select #Json = Replace(#Json, '"}]','"' + #nl + '}' + #nl + ']' + #nl + #nl)
Select #Json as FormattedJSON
And here is the fiddle with more improvements

Extract Certain String after Some Expression

I have table customer_info in which a column PrintData which contains many information. I would like to get Transaction id from that column.
The column data look like this:
<Line28>.TVR: 4000008000</Line28>
<Line29>.IAD: 06020103649D00</Line29>
<Line30>.TSI: E800</Line30>
<Line31>.ARC: 00</Line31>
<Line32>.CVM: PIN VERIFIED</Line32>
<Line33>.TRAN ID: 000000000075169</Line33>
I would like to get only 000000000075169 i.e. TRAN ID:
I have tried this as:
SUBSTRING(PrintData,CHARINDEX('TRAN ID: ',PrintData),CHARINDEX('</Li',PrintData))
but it is not giving write answer.

DECLARE #z NVARCHAR(MAX) = '
<Line28>.TVR: 4000008000</Line28>
<Line29>.IAD: 06020103649D00</Line29>
<Line30>.TSI: E800</Line30>
<Line31>.ARC: 00</Line31>
<Line32>.CVM: PIN VERIFIED</Line32>
<Line33>.TRAN ID: 000000000075169</Line33>
'
SELECT SUBSTRING(#z, CHARINDEX('TRAN ID: ', #z) + 9 -- offset charindex by 9 characters to omit the 'TRAN ID: '
, CHARINDEX('</Li', #z, CHARINDEX('TRAN ID: ', #z))-CHARINDEX('TRAN ID: ', #z) - 9) -- find the </Li AFTER the occurence of TRAN ID, and subract 9 to account for the offset
Yields 000000000075169.

Can you please with the following query.
DECLARE #PrintData AS VARCHAR (200) = '<Line33>.TRAN ID: 000000000075169</Line33>';
SELECT SUBSTRING(#PrintData,
CHARINDEX('TRAN ID: ', #PrintData) + LEN('TRAN ID: '),
CHARINDEX('</Li',#PrintData) - (CHARINDEX('TRAN ID: ', #PrintData) + LEN('TRAN ID: '))
);
The syntax is SUBSTRING (expression, start_position, length)
UPDATE:
As per the comment by MarcinJ, for the multiple instance of </Line, the folllowing query will work.
DECLARE #PrintData VARCHAR(2000) = '
<Line28>.TVR: 4000008000</Line28>
<Line29>.IAD: 06020103649D00</Line29>
<Line30>.TSI: E800</Line30>
<Line31>.ARC: 00</Line31>
<Line32>.CVM: PIN VERIFIED</Line32>
<Line33>.TRAN ID: 000000000075169</Line33>
';
DECLARE #FindString AS VARCHAR (20) = 'TRAN ID: ';
DECLARE #LenFindString AS INT = LEN(#FindString);
SELECT SUBSTRING(#PrintData,
CHARINDEX(#FindString, #PrintData) + #LenFindString,
CHARINDEX('</Line', #PrintData, CHARINDEX(#FindString, #PrintData)) - (CHARINDEX(#FindString, #PrintData) + #LenFindString)
);

I would simply use APPLY :
select #PrintData AS Original_string,
substring(tran_id, 1, charindex('</', tran_id) -1) as Tran_ID
from ( values ( substring(PrintData, charindex('TRAN ID:', PrintData) + 8, len(PrintData)) )
) t(tran_id);

SQL query variable nvarchar(max) can not store more than 4000 characters

I am having problem with dynamic sql query.
Declare sql query variable with nvarchar(max) and building dynamic query and then running it with using sq_executesql.
Please suggest if you have any solution for this.
Below are my code snippet:
DECLARE #count int, #sql nvarchar(max),#where nvarchar(max)
SELECT #count = 2, #where=' Where 1 = 1 '
set #sql = '

You need to explicit cast your large string to NVARCHAR(MAX) like this:
DECLARE #count int, #sql nvarchar(max),#where nvarchar(max)
SELECT #count = 2, #where=' Where 1 = 1 '
set #sql = '
SELECT top 2

When you are concatenating nvarchar(1-4000) strings the output string is not converted to max if it is not possible to store all the data. Also, in your example, you are concatenating a nvarchar value with the second large string which is varchar(4251). You can test what is the output parameter type very easy using sp_describe_first_result_set.
So, we have:
EXEC sp_describe_first_result_set #tsql = N'SELECT CAST(''a'' as nvarchar(50)) + cast(''b'' as varchar(4261)) as x'
and the result is a string as follows:
That's why we need to explicity convert the large string to NVARCHAR(MAX).

SQL Nested Replace Order

Dumb question, but can't seem to find a quick answer... I am creating UDF to replace name prefix with a nested replace... something like this:
REPLACE(
REPLACE(
REPLACE(
REPLACE(
REPLACE(
REPLACE(
REPLACE(
REPLACE(
#Name
, 'Mr ', '')
, 'Mrs ', '')
, 'Ms ', '')
, 'Dr ', '')
, 'Mr. ', '')
, 'Mrs. ', '')
, 'Ms. ', '')
, 'Dr. ', '')
but want to replace those containing a '.' BEFORE those without. What's the order/hierarchy of nested replace? TIA, Danny

Your inner most Replace will always run first on the character string. So from inner to outer is the order in which they will be executed. I suggest though trying a more elegant approach perhaps through the use of regex and case statements so it might be easier to maintain rather than just having a ton of nested replaces which don't necessarily all do work.

I suggest using a function like this in SQL:
CREATE FUNCTION [dbo].[ReplaceNamePrefix]
(#value NVARCHAR(50)
)
RETURNS NVARCHAR(50)
AS
BEGIN
DECLARE #RETURN NVARCHAR(50);
SET #RETURN = #value;
SET #RETURN = REPLACE(#RETURN, 'Mrs.', '');
SET #RETURN = REPLACE(#RETURN, 'Mrs', '');
SET #RETURN = REPLACE(#RETURN, 'Mr.', '');
SET #RETURN = REPLACE(#RETURN, 'Mr', '');
SET #RETURN = REPLACE(#RETURN, 'Ms.', '');
SET #RETURN = REPLACE(#RETURN, 'Ms', '');
SET #RETURN = REPLACE(#RETURN, 'Dr. ', '');
SET #RETURN = REPLACE(#RETURN, 'Dr', ''); ');
SET #RETURN = RTRIM(LTRIM(#RETURN));
RETURN #RETURN;
END;
Use the following command to get your goal:
SELECT [dbo].[ReplaceNamePrefix]('Dr. Danny Dennison');
the result is: Danny Dennison
But if you insist on using your own code, use the following:
SELECT REPLACE( REPLACE( REPLACE( REPLACE( REPLACE( REPLACE( REPLACE( REPLACE( 'MR Danny Dennison', 'Mrs.', '' ), 'Mrs', '' ), 'Mr.', '' ), 'Mr', '' ), 'Ms.', '' ), 'Ms', '' ), 'Dr. ', '' ), 'Dr', '' );

SQL Query to send e-mail based on records number

I have this sql query:

#profile_name = 'profile name',
#recipients='e-mail account',
#subject = 'e-mail subject',

But I need only send the e-mail if there are records on query.
Can someone help???
Thank you.

Just check for the existence of data first. Something like this:
