SQL Server 2012 :: Stored Procedure With Conditional IF Statement Logic
Aug 9, 2015
I have a data model with 7 tables and I'm trying to write a stored procedure for each table that allows four actions. Each stored procedure should have 4 parameters to allow a user to insert, select, update and delete a record from the table.
I want to have a stored procedure that can accept those 4 parameters so I only need to have one stored procedure per table instead of having 28 stored procedures for those 4 actions for 7 tables. I haven't found a good example online yet of conditional logic used in a stored procedure.
Is there a way to add a conditional logic IF statement to a stored procedure so if the parameter was INSERT, go run this statement, if it was UPDATE, go run this statement, etc?
I have attached my data model for reference.

Hello.Looking for a smarter way to code the following. I have a storedprocedure I will be passing several variables to. Some times, some ofthe fields used in a WHERE clause will not be passed, and I would liketo avoid having to code a bunch of if statements to set the executingcode. For example, below I would only like to execute the LIKEconditions only when the variable in question is not NULL. I did atest and if the variable is set to null, obviously the select does notreturn what I'm expecting.if @switch = "B"SELECT * from ikb whereikbtitle like @ins1 andikbtitle like @ins2 andikbtitle not like @ins3 andikbbody like @ins1 andikbbody like @ins2 andikbbody not like @ins3endThanks for any help or information with this.

I'm trying to convert the query immediately below into a function with the conditional logic to return a VARCHAR value with the gender: male, female or unknown.
SELECT empid, firstname, lastname, titleofcourtesy,
CASE
WHEN titleofcourtesy IN('Ms.', 'Mrs.') THEN 'Female'
WHEN titleofcourtesy = 'Mr.' THEN 'Male'
ELSE 'Unknown'
END AS gender
FROM HR.Employees;
GO
Below is the conditional logic function I'm trying to create to replicate the logic above.
CREATE FUNCTION dbo.Gender
(
@male AS VARCHAR(10),
@female AS VARCHAR(10),
@unknown AS VARCHAR(10)
)
RETURNS VARCHAR(10)
[Code] .....

I am writing a stored procedure that takes in a customer number, a current (most recent) sales order quote, a prior (to most current) sales order quote, a current item 1, and a prior item 1, all of these parameters are required.Then I have current item 2, prior item 2, current item 3, prior item 3, which are optional.
I added an IF to check for the value of current item 2, prior item 2, current item 3, prior item 3, if there are values, then variable tables are created and filled with data, then are retrieved. As it is, my stored procedure returns 3 sets of data when current item 1, prior item 1, current item 2, prior item 2, current item 3, prior item 3 are passed to it, and only one if 2, and 3 are omitted.I would like to learn how can I return this as a one data set, either using a full outer join, or a union all?I am including a copy of my stored procedure as it is.

I have a stored procedure that ends with
Select columnname from tablename order by ordercolumn
We will call that "sp_foldersOfFile". It takes 1 parameter, a fileID (int) value.
The result when I execute this from within Management Studio is a single column of 1 to n rows. I want to use these values in another stored procedure like this:
Select @userCount = COUNT(*) from permissions where UserID = @userID and
(projectid = @projectID or projectid=0) and
clientid = @clientID and
folderpermissions in (dbo.sp_FoldersOfFile(@fileID))
The Stored Procedure compiles but it does not query the folderpermissions in the selected values from the sp_FoldersOfFile procedure. I'm sure it is a syntax issue.

I have a stored proc that contains an update which utilizes a case statement to populate values in a particular column in a table, based on values found in other columns within the same table. The existing update looks like this (object names and values have been changed to protect the innocent):
UPDATE dbo.target_table
set target_column =
case
when source_column_1= 'ABC'then 'XYZ'
when source_column_2= '123'then 'PDQ'
[Code] ....
The powers that be would like to replace this case statement with some sort of table-driven structure, so that the mapping rules defined above can be maintained in the database by the business owner, rather than having it embedded in code and thus requiring developer intervention to perform changes/additions to the rules.
The rules defined in the case statement are in a pre-defined sequence which reflects the order of precedence in which the rules are to be applied (in other words, if a matching value in source_column_1 is found, this trumps a conflicting matching value in source_column_2, etc). A case statement handles this nicely, of course, because the case statement will stop when it finds the first "hit" amongst the WHEN clauses, testing each in the order in which they are coded in the proc logic.
What I'm struggling with is how to replicate this using a lookup table of some sort and joins from the target table to the lookup to replace the above case statement. I'm thinking that I would need a lookup table that has column name/value pairings, with a sequence number on each row that designates the row's placement in the precedence hierarchy. I'd then join to the lookup table somehow based on column names and values and return the match with the lowest sequence number, or something to that effect.

I have a stored procedure that I have written that manipulates date fields in order to produce certain reports. I would like to add a column in the dataset that will be a join from another table (the table name is Periods).
The structure of the periods table is as follows:
[ID] [int] NOT NULL,
[Period] [int] NULL,
[Quarter] [int] NULL,
[Year] [int] NULL,
[PeriodStarts] [date] NULL,
[PeriodEnds] [date] NULL
The stored procedure is currently:
USE [International_Forecast_New]
GO
/****** Object: StoredProcedure [dbo].[GetOpenResult] Script Date: 01/07/2014 11:41:35 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
[Code] ....
What I need is to add the period, quarter and year to the dataset based on the "Store_Open" value.
For example Period 2 looks like this
Period Quarter Year Period Start Period End
2 1 20142014-01-27 2014-02-23
So if the store_open value is 02/05/2014, it would populate Period 2, Quarter 1, Year 2014.

I have a table containing a 'queue' of rows waiting to be processed by my application.
Is it possible to call a single stored procedure that selects a row, returns the data and then deletes the row ?
If not, what is the best logic for doing it with two stored procedures ?
The table contains a unique ID, DateTime and nVarChar colums and I could easily add a 'flag' if required.
Any suggestions appreciated.
Steve.

Hi
i have written a script that collects the applications and the components each application uses.
I wanted to create a stored procedure so that i could get a snapshot of the application and the components that an application has at a given time.
i have the following database structure
CREATE TABLE [Components] (
[CompID] [int] IDENTITY (1, 1) NOT NULL ,
[RT] [nchar] (7) COLLATE Latin1_General_CI_AS NOT NULL ,
[Name] [nchar] (50) COLLATE Latin1_General_CI_AS NULL ,
[Version] [smallint] NULL ,
PRIMARY KEY CLUSTERED
(
[CompID]
) ON [PRIMARY]
) ON [PRIMARY]
GO
CREATE TABLE [ApplicationID] (
[ApplicationID] [int] IDENTITY (1, 1) NOT NULL ,
[NodeID] [nchar] (15) COLLATE Latin1_General_CI_AS NULL ,
[WinVer] [nchar] (40) COLLATE Latin1_General_CI_AS NULL ,
[Hw] [nchar] (40) COLLATE Latin1_General_CI_AS NULL ,
[BT] [nchar] (20) COLLATE Latin1_General_CI_AS NULL ,
[MT] [nchar] (20) COLLATE Latin1_General_CI_AS NULL ,
[Cust] [nchar] (20) COLLATE Latin1_General_CI_AS NULL ,
[BVer] [nchar] (10) COLLATE Latin1_General_CI_AS NULL ,
[BRel] [nchar] (10) COLLATE Latin1_General_CI_AS NULL ,
[WStyle] [nchar] (15) COLLATE Latin1_General_CI_AS NULL ,
[DateInst] [datetime] NULL ,
[SnapDate] [datetime] NULL ,
PRIMARY KEY CLUSTERED
(
[ApplicationID]
) ON [PRIMARY]
) ON [PRIMARY]
GO
CREATE TABLE [AppComponents] (
[ApplicationID] [int] NOT NULL ,
[CompID] [int] NOT NULL ,
[InsT] [datetime] NULL ,
[Installed] [bit] NULL ,
[SnapDate] [datetime] NOT NULL ,
CONSTRAINT [FK_AppsComponents_ApplicationID] FOREIGN KEY
(
[ApplicationID]
) REFERENCES [ApplicationID] (
[ApplicationID]
),
CONSTRAINT [FK_AppsComponents_Components] FOREIGN KEY
(
[CompID]
) REFERENCES [Components] (
[CompID]
)
) ON [PRIMARY]
GO
is there a way of checking if the component is already in the data base if it is then just get the CompID and attach that CompId in the AppsComponents link table and put that in the AppComponents table. the snapdate field is to be the current datetime when the data is collected. Is there a current date function in SQL server? Is it possible to do this in a stored procedure?

I have a stored procedure using UNION joins on three SQL queries.
Sadly, I'm only now learning how to use Stored Procedures, so if this is a really dumb question, please forgive me. I'm not used to big UNION statements like this either... usually I'm just programming websites to serve information out pretty simply :)
I need to return one result set, sorted by date... one complete result per day. eg: 5/15/2007 | XX | XX | XX | XX | XX | XX |5/16/2007 | XX | XX | XX | XX | XX | XX |5/17/2007 | XX | XX | XX | XX | XX | XX |
Currently, when I run the query, I'm getting three separate date values for each date...
eg:5/15/2007 | XX | XX | 00 | 00 | 00 | 00 |5/15/2007 | 00 | 00 | XX | XX | 00 | 00 |5/15/2007 | 00 | 00 | 00 | 00 | XX | XX |5/16/2007 | XX | XX | 00 | 00 | 00 | 00 |5/16/2007 | 00 | 00 | XX | XX | 00 | 00 |5/16/2007 | 00 | 00 | 00 | 00 | XX | XX |etc
How do I fix this? I've looked through my query ad naseum and don't see anything that sets me off as "wrong".
Here is the stored procedure if you can help. I'd really really love the help!
C R E A T E P R O C E D U R E sp_ApptActivityDate
(@strWHERE as varchar(500), @strWHERECANCELED as varchar(500))

On SQL 2012 (64bit) I have a CLR stored procedure that calls another, T-SQL stored procedure.
The CLR procedure passes a sizeable amount of data via a user defined table type resp.table values parameter. It passes about 12,000 rows with 3 columns each.
For some reason the call of the procedure is verz very slow. I mean just the call, not the procedure.
I changed the procdure to do nothing (return 1 in first line).
So with all parameters set from
command.ExecuteNonQuery()to
create proc usp_Proc1
@myTable myTable read only
begin
return 1
end
it takes 8 seconds.I measured all other steps (creating the data table in CLR, creating the SQL Param, adding it to the command, executing the stored procedure) and all of them work fine and very fast.
When I trace the procedure call in SQL Profiler I get a line like this for each line of the data table (12,000)
SP:StmtCompleted -- Encrypted Text.
As I said, not the procedure or the creation of the data table takes so long, really only the passing of the data table to the procedure.

Using: SQL Server 7.0
Is there any way to use conditional SQL in the SELECT clause of a stored procedure, i.e., use an IF-THEN to SELECT either COUNT(*) or a column-list based on the value of a parameter passed to the stored procedure? (I'd like to avoid having two sets of queries with the same WHERE clause).

I want to return a subset of data from my 'items' table using a stored procedure based on a number of parameters as follows :
customer code varchar(8)
userid varchar(10)
status tinyint
where the customer code can be any valid customer code OR blank, the userid can be any valid userid or blank and the status can be 1 (item is open), 2 (item is closed) or 3 (item is open or closed, i.e. no filter on status)
Is there a better way to achieve this than the following disaster:
IF LEN(RTRIM(LTRIM(@custcode))) = 0
BEGIN
IF LEN(RTRIM(LTRIM(@userid))) = 0

IF @status = 1

Is there a simple way to do conditional totaling?
I have a table that has incremental values, so the maximum value is the current total, however on occassion the value is reset and the increment begins anew. What I need to do is get the total the maximum value each time it is reset.
ie.
Value Date
----- -----
12 1-1
14 1-2
100 1-8
35 1-10
50 1-12
5 1-15
the total would be 155 (100 + 50 + 5)

Hi all,
I created a stored procedure which perfoms a simple select like this:
CREATE PROCEDURE Reports_Category
( @loc varchar(255), @pnum varchar(255) )
AS declare @vSQL nvarchar(1000) set @vSQL = 'SELECT ' + @loc + ', ' + @pnum + ' FROM Category ' exec sp_executesql @vSQL
RETURNGO
It takes field names as parameters. What happens is that when I supply value to only one parameter, the procedure gives error as it is expecting both values. Is there a way to make these parameters work like an 'OR' so that the procedure returns a dataset even if there is only one value supllied.
Please help,
Thanks,

Hi,
I'm converting some direct SQL queries into stored procedures. The
original queries have conditional parts appended depending on certain
parameters like this:
Sql = "First part"
If certain condition then
Sql &= "Second part"
Endif
How could I do this in a stored procedure? So far I have made them like this:
IF @condition > 0
Fist part Second part
ELSE
First part
You can see that I have to maintain 'First part' in two locations. What is a better way of dealing with this?
Thanks!

I have a table like this

The value that you are passing is numeric and numeric with only decimal 0 value, and then convert it to integer otherwise leave as it is
So if I run a query something like this
Select value, fn_convertointerger(value) as converted_value from TableA
I will get
Value converted_value
* *
001 1
004.00 4
3.0 3
1.22 1.22
2.02 2.02
