Prerequisite for Data examples

In order to make the usage examples of various Data blocks clear and easy to understand, we have created a common background or scenario, which we will explain in this section.

Introduction Video

The following video serves as a great introduction to databases and also provides a general overview of data features in your Zingy app.

Table Information

We will continue to use the example Customers Database Table presented in the above video and also detailed below:

Example Database Table about Customers

Sample Records

We will use the following sample records for the Customers Database Table.

Example records for the Customers table

Sample Queries

The following queries are part of the Customers Database Table.

• NameMatch

  

  This query will list records where either the value of the FirstName OR the LastName fields, contains the text specified in the Input-1 parameter.

• NamePhoneMatch

  

  This query will list records where the PhoneNumber field contains the text specified in the Input-2 parameter AND either of the FirstName or the LastName fields, contains the text specified in the Input-1 parameter.

Database Reading Logic for examples

For Page Flow/Cloud Flow blocks that are related to reading of database records, the following base logic is used:

• The Data Read block is used to read from the Customers Database Table with the dataset name of ds1.
• The Data Status block is then used to check the status.
• In the Success Tasks Flow Parameter of the Data Status block, the function Usage Example is invoked.
• All examples will be shown implementing the Usage Example function containing the specific block being explained.
