SQL For Json path - auto inserted '\' if parameter content '/' - sql

Declare #ContractCode nvarchar(100) = N'02/HĐLĐ-NGG';
Declare #DateStartWork date = '2020-06-01';
Declare #DeptID int = 2;
Declare #PositionID int = 4;
Declare #HRDecisionID int = 614
Select #ContractCode as ContractCode,
#DateStartWork as DateStartWork,
#DeptID as DeptID,
#HRDecisionID as HRDecisionID
For Json Path
Then the Result =
[{"ContractCode":"02\/HĐLĐ-NGG","DateStartWork":"2020-06-01","DeptID":2,"HRDecisionID":614}]
Instead of right value like:
[{"ContractCode":"02/HĐLĐ-NGG","DateStartWork":"2020-06-01","DeptID":2,"HRDecisionID":614}]
So please help me to answer Why it automatically inserted \ before '/' into ContractCode.

How to return true=1 or false=0 when updating

ALTER PROCEDURE [dbo].[Proc_Erp_Branch_Update]
#Id int,
#Code varchar(20),
#Name nvarchar(50),
#IsActive bit=1,
#UpdateBy varchar(50),
#ImgId int
AS
BEGIN
IF EXISTS (SELECT* FROM Branch WHERE Id = #id AND IsDelete =0)
BEGIN
UPDATE Branch
SET Code = ISNULL(#Code,Code),
Name = ISNULL( #Name,Name),
IsActive = ISNULL( #IsActive,IsActive),
UpdatedBy = ISNULL( #UpdateBy,UpdatedBy),
ImageId = ISNULL( #ImgId,ImageId)
output deleted.Id
WHERE Id = #Id AND IsDelete = 0
END
ELSE
BEGIN
SELECT 0
END
END
Why does the procedure always return 0 even though the update statement appears to be successful in the [dbo].[Proc_Erp_Branch_Update]?
How do I resolve this?
var query = "Proc_Erp_Position_Update";
var res = await con.QueryFirstOrDefaultAsync<int>(query, new { Id = model.Id, Code = model.Code, Name = model.Name, IsAtive = model.IsActive, UpdatBy = username, ImageId = imgid.HasValue? imgid : 0 }, commandType: System.Data.CommandType.StoredProcedure);
return res;
res always returns 0
res will always be 0 since if your procedure does find the row and update it, it will not select any value - and the default for int in dot net is 0.
However, there is another problem in your procedure - there is a chance, though admittedly a small chance, that the relevant row will be changed or deleted between the select statement in the exists condition and the update statement that follows.
Luckily, there's an easy fix for that - simply remove the if.
Executing a stored procedure will return, by default, the number of rows effected, so you can simply use con.ExecuteAsync to get that number.
SQL:
ALTER PROCEDURE [dbo].[Proc_Erp_Branch_Update]
#Id int,
#Code varchar(20),
#Name nvarchar(50),
#IsActive bit=1,
#UpdateBy varchar(50),
#ImgId int
AS
BEGIN
UPDATE Branch
SET Code = ISNULL(#Code,Code),
Name = ISNULL( #Name,Name),
IsActive = ISNULL( #IsActive,IsActive),
UpdatedBy = ISNULL( #UpdateBy,UpdatedBy),
ImageId = ISNULL( #ImgId,ImageId)
WHERE Id = #Id AND IsDelete = 0
END
C#:
var query = "Proc_Erp_Position_Update";
var res = await con.ExecuteAsync(query, new { Id = model.Id, Code = model.Code, Name = model.Name, IsAtive = model.IsActive, UpdatBy = username, ImageId = imgid.HasValue? imgid : 0 }, commandType: System.Data.CommandType.StoredProcedure);
return res;
Note: I'm assuming you're using c# and Dapper based on the code you've shown in your question.

SQL stored procedure call failed with index out of range

I am trying to execute a stored procedure in SQL Server from my java code. This stored procedure is used in some other language and it was working fine from long back. Now I need to integrate it in my java app. I have 15 columns in my table. When I tried this in my java code, its throwing

Script to check changes on SQL Server Instance?

Is there any SQL script to check the changes on SQL Server instance made by other DB admin and i get email alert of that changes. if yes, then please provide me the script and all the steps for applying it. I am using SQL Server 2012.
One solution is to use a DDL trigger to catch all schema changes (procedures, functions, table definition etc.). This can work for all non-encrypted objects and of course, other admins must not disable it.
More details about how to write such a trigger and persist changes can be found here.
[Later edit]
I remembered I have created such an audit on the development environment and I can provide a custom version based on the indicated article. Besides usual information, I have also included a "distance" between old object text and new object text to have a basic idea about change magnitude.
1) Table definition:
IF OBJECT_ID('dbo.DDLEvents', 'U') IS NULL
BEGIN
CREATE TABLE dbo.DDLEvents
(
EventId INT IDENTITY(1, 1) NOT NULL,
EventDate DATETIME NOT NULL DEFAULT CURRENT_TIMESTAMP,
EventType NVARCHAR(64),
EventXML XML,
DatabaseName NVARCHAR(255),
SchemaName NVARCHAR(255),
ObjectName NVARCHAR(255),
HostName VARCHAR(128),
IPAddress VARCHAR(32),
ProgramName NVARCHAR(255),
LoginName NVARCHAR(255),
ObjectDefinition NVARCHAR(MAX),
LastObjDefinition NVARCHAR(MAX),
Diff INT -- edit distance between last and current object version (gives an idea of how much was changed in the object)
);
create index IDX_DDLEvents_Object ON DDLEvents (SchemaName, ObjectName)
END
go
2) Initial text for existing objects:
IF NOT EXISTS(SELECT * FROM dbo.DDLEvents)
BEGIN
INSERT INTO dbo.DDLEvents
(EventType, DatabaseName, SchemaName, ObjectName, LoginName, ObjectDefinition)
SELECT 'CREATE_PROCEDURE', DB_NAME(), OBJECT_SCHEMA_NAME([object_id]), OBJECT_NAME([object_id]), 'SYSTEM', OBJECT_DEFINITION([object_id])
FROM sys.procedures;
INSERT INTO dbo.DDLEvents
(EventType, DatabaseName, SchemaName, ObjectName, LoginName, ObjectDefinition)
SELECT 'CREATE_VIEW', DB_NAME(), OBJECT_SCHEMA_NAME([object_id]), OBJECT_NAME([object_id]), 'SYSTEM', OBJECT_DEFINITION([object_id])
FROM sys.views;
INSERT INTO dbo.DDLEvents

FROM sys.objects
-- scalar, inline table-valued, table-valued
WHERE type IN ('FN', 'IF', 'TF')
END
go
3) Distance function (CLR):

public static int Levenshtein(SqlString S1, SqlString S2)

if (S1.IsNull)
S1 = new SqlString("");

// keeping only the first part of the string (performance reasons)
String SC1 = S1.Value.ToUpper();
String SC2 = S2.Value.ToUpper();
if (SC1.Length > maxLen)
SC1 = SC1.Remove(maxLen);
if (SC2.Length > maxLen)
SC2 = SC2.Remove(maxLen);
int n = SC1.Length;
int m = SC2.Length;
short[,] d = new short[n + 1, m + 1];
int cost = 0;

for (short j = 0; j <= m; j++)
d[0, j] = j;
for (int i = 1; i <= n; i++)
{
for (int j = 1; j <= m; j++)
{

else
cost = 1;
d[i, j] = (short) System.Math.Min(System.Math.Min(d[i - 1, j] + 1, d[i, j - 1] + 1), d[i - 1, j - 1] + cost);
}
}
// double percentage = System.Math.Round((1.0 - ((double)d[n, m] / (double)System.Math.Max(n, m))) * 100.0, 2);
// return percentage;
return d[n, m];
}

Although I send the parameter I get "Can not insert NULL value..."

I am developing an ADO.NET application. At some point in the DAL I call a stored-procedure named "CREATE_CUSTOMER". Although I set the SHORT_NAME field I still get the
"Msg 515, Level 16, State 2, Procedure CREATE_CUSTOMER, Line 29
Cannot insert the value NULL into column 'SHORT_NAME', table 'MYDB.app.CUSTOMER';
column does not allow nulls. INSERT fails." error.
When I inspect the query with the SQL profiler I get the following SQL runs on the server. As I Copy&Paste it to a new Query Window I still get the same error.
Do I miss something?

Your code is the equivalent of doing this:
DECLARE #SHORT_NAME nvarchar(11) = N'NEW Corp';
...
EXEC [app].[CREATE_CUSTOMER];
You are just declaring the parameters, never actually passing them to the procedure invocation. Your code should be like this:
exec sp_executesql N'[app].[CREATE_CUSTOMER] #SHORT_NAME, #MAIL_NAME, ...',
N'#SHORT_NAME nvarchar(11),
#MAIL_NAME nvarchar(18),
...',
#SHORT_NAME=N'NEW Corp',
#MAIL_NAME=N'NEW Corporation',
...
You must not only declare the parameters you pass to the batch, you must also use them when you invoke the procedure.
When I inspect the query with the SQL profiler I get the following SQL runs on the server. As I Copy&Paste it to a new Query Window I still get the same error
This sounds suspiciously like you are using a SqlCommand but forgot to set the CommandType to Procedure. the default is Text and will behave exactly as you observed.
Do not assign null values to ur variable, try only with DECLARING it as bellow
DECLARE #SHORT_NAME varchar(250) ,
instead of
#SHORT_NAME varchar(250) = NULL,

Issue with SQL Stored Procedure Note Returning Values when passing in NULLS

I have a stored procedure that I created and sometimes there are parameters that pass in a NULL value. I set up the stored procedure to take this into account, but every time I pass in a NULL value it doesn't return anything even if some of the other parameters are passed in. Can you please help? Here is my stored procedure. I'm not sure if it's the join that isn't correct or what.
Thanks.

#CollectionID int = NULL,

RETURN
What I do in these scenarios is change the default for #ProductId to -1
DO NOT SEND ANY VALUE FOR THE PARAMETER, IF YOU SEND A NULL THEN IT WILL USE THAT VALUE. DEFAULT VALUES ARE ONLY USED WHEN THE PARAMETER IS NOT SENT.
#ProductID int = -1,
#CollectionID int = NULL,
#ApplicationID int = NULL,
#StyleID int = NULL
WHERE (#ProductID = -1 OR dbo.CrossoverDesignTable.ProductID = #ProductID)
AND .....
Assuming -1 is a value you don't have, I recommend you use this:
ISNULL(dbo.CrossoverDesignTable.ProductID, -1) = ISNULL(#ProductID, -1)
instead of:
dbo.CrossoverDesignTable.ProductID = #ProductID OR #ProductID IS NULL
and do the other comparisons in the same way.
If you want to keep your approach, you should do it this way, I think.
( (#ProductID is null) AND (dbo.CrossoverDesignTable.ProductID is null) )
OR (dbo.CrossoverDesignTable.ProductID = #ProductID)
