When a variable is declared as a LIST data type or a Key-Value data type, it can only hold values that are applicable to that particular data type. The number of iterations is the number of values present in the collection. In other words, the iteration variable - value holds the first value on the first iteration, the second value on the second iteration, and so forth. It holds every value in the collection, one at a time. If a new value is inserted with an existing key, it will overwrite the existing value. Instead, the values are identified by their associated keys. The key-value collection does not hold values in an ordered manner. The index of Shawn, Alan, and Kate are 0, 1, and 2 respectively. Therefore, the index starts from 0 and extends up to 2. Note that for a collection that has "n" number of elements, the indexes range from 0 to (n-1). The index of the first value in a collection is always 0 and the subsequent values are 1, 2, 3, and so forth. The indexes are numbers that identify values in a collection. The order is marked by a value positioning entity, index. The index-value collection holds the data in an ordered manner, i.e., it retains the order in which the values are inserted. The following two types are the broad classification of collection. Or, the values themselves could be collections. The values in a collection can be of any basic data type. OverviewĬollection allows you to store, insert, retrieve, delete, and manipulate a group of data. To learn about a collection variable, which is used to hold a collection of records in Zoho Creator, refer to this page. That is why this block has a socket for plugging in expressions.Note: Collection data type is not to be confused with a collection variable. NOTE: This block differs from the block described above because it is a RETURN block. This way all variables in this procedure will all start with the same value each time the procedure is run. This block is a mutator that allows you to create new variables that are only used in the procedure you run in the RETURN part of the block. You can rename the variables in this block at any time and any corresponding blocks elsewhere in your program that refer to the old name will be updated automatically initialize local name to - in (return) That is why this block has space inside for statement blocks to be attached. NOTE: This block differs from the block described below because it is a DO block. This block is a mutator that allows you to create new variables that are only used in the procedure you run in the DO part of the block. Once a variable v is selected, you can attach a block to give v a new value. Only variables in scope will be available in the dropdown. This block follows the same rules as get. This block provides a way to get any variables you may have created. You can rename this block at any time and any associated blocks referring to the old name will be updated automatically. Global variables can be changed while an app is running and can be referred to and changed from any part of the app even within procedures and event handlers. Global variables are used in all procedures or events so this block will stand alone. Clicking on name will change the name of this global variable. It takes in any type of value as an argument. This block is used to create global variables. There are five main types of variable blocks:
