Execute Dynamic SQL commands in SQL Server

-
In some applications having hard-coded SQL statements is not appealing, because of the dynamic nature of the queries being issued against the database server. Because of this sometimes there is a need to dynamically create a SQL statement on the fly and then run that command. This can be done quite simply from the application perspective where the statement is built on the fly whether you are using ASP.NET , ColdFusion or any other programming language. But how do you do this from within a SQL Server stored procedure? SQL Server offers a few ways of running a dynamically built SQL statement. These ways are: Writing a query with parameters Using EXEC Using sp_executesql Writing a query with parameters This first approach is pretty straightforward if you only need to pass parameters into the WHERE clause of your SQL statement. Let’s say we need to find all records from the Customers table where City = ‘London’. This can be done easily as the following example shows.

How to rename a Stored Procedure in SQL

-

Sometimes by mistake, if you create a wrongly named stored procedure, you can easily rename the store procedure.
Checkout following commands for renaming the stored procedure

Syntax:

sp_rename 'procedure_name1', 'procedure_name2'
  • procedure_name1 The current name of the stored procedure
  • procedure_name2 The new name of the stored procedure.

A stored procedure can be renamed. The new name should follow the rules for identifiers.

Examples


`EXEC sp_rename 'spGetAvgGrade', 'spNewAvgGrade';`
Output:

Caution: Changing any part of an object name could break scripts and stored procedures. The object was renamed to ‘spNewAvgGrade’.`

Explanation:

In the above example, we change the name of the stored procedure spGetAvgGrade to spNewAvgGrade.

Check If Temporary Table Exists

-
When working with temporary tables in SQL Server, the common conundrum is often determining whether a temp table exists before performing operations on it. In this blog post, we’ll delve into the nuances of checking the existence of temp tables and explore the potential pitfalls and solutions. The Basics: Local Temp Tables To check if a local temp table exists, one commonly used approach is: IF OBJECT_ID ( 'tempdb..#temp' ) IS NOT NULL BEGIN PRINT '#temp exists!' END ELSE BEGIN PRINT '#temp does not exist!' END This method utilizes the OBJECT_ID function to verify the existence of the temp table in the tempdb database. The Undocumented Second Parameter An alternative way involves an undocumented optional second parameter: IF OBJECT_ID ( 'tempdb..#temp' , 'u' ) IS NOT NULL BEGIN PRINT '#temp exists!' END ELSE BEGIN PRINT '#temp does not exist!' END However, it’s important to no

Multiple NULL values in a Unique index in SQL

-
this project needed to support having multiple NULL values in the column and still have a UNIQUE constraint . That is allowed by Oracle but not in SQL Server and DB2 LUW. There is a way to make this work in SQL Server and DB2 LUW also but that requires a work -around. Consider this table : CREATE TABLE TEST_UQ (COL1 INT IDENTITY (1,1) PRIMARY KEY , COL2 NVARCHAR(10) NULL ) GO In this table , COL1 has been declared as the primary key but we want a UNIQUE constraint to be put on COL2 as well. Please note that COL2 is a nullable column and that SQL Server does not allow multiple NULL values in a UNIQUE index and treats them the same way. We can test it out prior to proceeding with the work -around: Let tus create a unique index first : CREATE UNIQUE INDEX TEST_UQ_IND_1 ON TEST_UQ (COL2) GO Now, let us try to insert these values : insert into test_uq (col2) values (’abc’); insert into test_uq (col2) values (’xyz’); insert into

Row To Column

Suppose you have a table structure like create table tmpStocks ( [StockSymbol] [char] (8), [ExchMM] [varchar] (10) ) go create table tmpExchanges ( [Name] [char] (10), [ExchSymbo] [char] (1) ) go 2. Insert some values: insert into tmpStocks (stocksymbol,exchmm) values ('KS','IP') insert into tmpStocks (stocksymbol,exchmm) values ('PK6','IB') insert into tmpStocks (stocksymbol,exchmm) values ('LHJ','I') insert into tmpStocks (stocksymbol,exchmm) values ('JHL','P') insert into tmpExchanges (name,ExchSymbo) values ('ISE','I') insert into tmpExchanges (name,ExchSymbo) values ('BOX','B') insert into tmpExchanges (name,ExchSymbo) values ('PCost','P') and you want result like how to get the results as following: [StockSymbol] [ExchMM] [ISE] [BOX] [PCost] ks IP 1 0 1 PK6
