Sql if else not working

Try using just if instead of else if. If Else not working in TSQL - Stack. SQL Server : IF ELSE condition not working. I am trying to get SQL to look through the stg tbale and find matches in the dbo table. If there are matches then I would like the dbo table updated and if there are no matches in the stg table then I would like that data inserted into the dbo table.

So far I have come up with the following code but the ELSE statement is being ignored. Currently i am using lots of if…. After seeing this articles i am planning to change my if. IF NOT EXISTS, but i am getting a small problem while using this query. This query is not working for tables that do’t have any records.

Can u help me regarding this. SQL If statement will test the condition first and depending upon the result it will execute the statements. Unless a statement block is use the IF or ELSE condition can affect the performance of only one Transact- SQL statement.

To define a statement block, use the control-of-flow keywords BEGIN and END. IIF is a shorthand method for performing an IF. Restructuring our above example to use IIF is quite simple.

IF-ELSE statement is not working in T- SQL. Imposes conditions on the execution of a Transact-SQL statement. The Transact-SQL statement ( sql _statement) following the Boolean_expressionis executed if the Boolean_expression evaluates to TRUE. The optional ELSE keyword is an alternate Transact-SQL statement that is executed when Boolean_expression evaluates to FALSE or NULL. They are only allowed in functions and stored procedures.

Maybe Case is not what I am looking for. Is there a way to do that? Since the ELSE condition is optional, you are not required to include the ELSE condition in the IF. The SQL NOT condition (sometimes called the NOT Operator) is used to negate a condition in the WHERE clause of a SELECT, INSERT, UPDATE, or DELETE statement.

It will check for the first condition, if the condition is TRUE then it will execute the statements present in that block. An IF-THEN statement can be followed by an optional ELSIF. As we all know that stored procedure is faster than LINQ, so we will fetch data from database using stored procedure. So if you place a GO, the IF statement ends there and the other sql code lines after GO are executed as a new batch. I have a query that I wrote utilizing a CASE statement.

I have WHEN statements and one ELSE statement. The query is working as expected except for the ELSE statement. I get no syntax errors it just not hitting the ELSE case when it shoul and instead returns nothing.

Not sure why the expresssion are not working in T- SQL. I appreciate your responses. All you programmers out there who have been following this tutorial are probably salivating now at the prospect of getting stuck into some proper programming. Salivate not , because.

This SQL tutorial explains how to use the SQL NOT condition with syntax and examples. The ELSE clause has no condition evaluation and the THEN key word is omitted. If the condition is true, one record is inserted into the customer table. When i run the code, the SP are not doing the job. But if I exec them alone, they work fine.

Notwithstanding the hint above, there is a place for IF statements in SQL. Greetings, I have an IF ELSE SQL query to display in a Gridview. Basically, there is a textbox that would pull a specific query to the Gridview.

In the event that the box is null, the query would pull into the gridview all rows with incident type Deployer and not in Complete status. If it fails the first test, then it will look at the initial ELSE test and if it meets that criteria, it will carry out the task but not look at any further ELSE options. The code continues in this way until either one match has been found actioned or the end of the code is reached. Once a condition is found to be TRUE, the IF -THEN- ELSE statement will execute the corresponding code and not evaluate the conditions any further. If no condition is met, the ELSE portion of the IF -THEN- ELSE statement will be executed.

It is important to note that the ELSEIF and ELSE portions are optional.
