nested if else in mysql stored procedure

IF ( @count = 1 ) (SELECT skumaster.sku AS SKU, ( skumaster.minimumstock - Count(*) ) AS ReorderQuantity, 'LowInventory' AS Description FROM skumaster skuMaster JOIN inventorymaster inventoryMaster ON skumaster.sku = … Often I create a stored procedure I refer to as a switching yard. END IF blocks may be nested within other flow-control constructs, including other IF statements. Is this not possible in a stored procedure? I'm inserting real-time data throughout the day in stockData table. The stored procedure GetCustomerLevel() accepts two parameters: pCustomerNumber and pCustomerLevel.. First, select creditLimit of the customer specified by the pCustomerNumber from the customers table and store it in the local variable credit. In this case we must also issue a ROLLBACK only in the procedure where the outermost transaction is opened, but if @@TRANCOUNT>1 in the inner procedure we need to issue a COMMIT even in case of failure to end the procedure with the same value of … Here is the output: In this Stored procedure (called by this inventory-checking function), many if else if statement are used.How can it be improved? 1. I'm having trouble figuring out how to loop through a table within a stored procedure and use the results as a parameter into another stored procedure that inserts the parameter. For example; Create Procedure Test Variable VARCHAR(10) AS If Variable = Whatever Nesting IF's in Stored Proc - Microsoft SQL / MS SQL Server Therefore, the nested IF statement executes. Its only purpose is to give an application one Sp to execute. The PRINT 'x > 0 and x < y'; statement in the IF branch executes. ; Then, set value for the OUT parameter pCustomerLevel to PLATINUM if the credit limit of the customer is greater than 50,000. Something I've rarely needed to use, but recently rediscovered is using nested inline MySQL IF statements in select queries to conditionally assign a value. In this article, we will talk about IF and Else control structure which will work inside the procedure and how an if function, which will even work in the simple query too, explained below. You can use indentation to make nested flow-control blocks more easily readable by humans (although this is not required by MySQL… Finally, the nested IF statement check if @x is less than @y ( @x < @y). Because @y is set to 20, the condition (@x < @y) evaluates to true. If and Else control structure works only inside of a procedure. The MySQL stored program language uses three-valued logic; just because a statement is NOT TRUE does not mean that it is necessary FALSE—it could be NULL. We can use If and else control structure in two ways in MySQL. It's pretty simple. If that doesn't make sense, read on. MySQL IF() Function String Value Example MySQL IF() Function Number Value Example MySQL Stored Procedure Function: Making hello world Function using aliase Example MySQL Stored Procedure: Creating Table using Stored Procedure Example Parentheses in SQL Command MySQL Example Aliase column name in SQL Command MySQL Example We can also use another approach allowing the inner procedures to open transactions without checking if there are open transactions. Each IF must be terminated by its own END IF followed by a semicolon. IF and ELSE control structure. Now what I'm attempting to do is update another table (stockDataStats) that get it's results from the stored procedure I'm trying create: CREATE TABLE stockDataStats(stockSymbol VARCHAR(10) PRIMARY KEY, AvgBid DOUBLE, AvgAsk DOUBLE, AvgLast DOUBLE, AvgVolume DOUBLE) Example: CREATE PROCEDURE GetColumnData() You should think carefully about the readability of your statements—sometimes a nested set of IF or CASE statements will be more readable and possibly more efficient.
