The Multiple Record Retrieval template is a versatile tool for developers looking to build a wide range of web applications. Whether you are designing simple applications, such as a customer master search, or complex applications, such as a shopping cart, the Multiple Record Retrieval template is worth considering. The design of this template features displaying data in a grid layout. Additionally, it supports ad-hoc sorting and searching to allow end-users to quickly and easily find important data.

Features that Apply to All m-Power Templates

Features that Apply to the Multiple Record Retrieval Template

All Templates Features:

Query Database Table:
m-Power templates allow you to retrieve rows of data from one or more database tables or database views. Utilizing SQL statements, m-Power connects to your database and allows you to access the data via a web application.
Back To Diagram

Ad Hoc Template Specific:
m-Power templates allow the end user to sort the data fetched from the database. Ascending or descending order can be controlled from the table heading by clicking the up or down arrows. To turn this feature on or off, access the application properties and select Yes or No for the advancedSort property.

Format Numeric Data:
m-Power templates allow developers to easily modify the numeric format of fields to better suit your needs, directly from the interface. An example of this can be the use of a comma at the thousand decimal point: (2,000) or the inclusion of decimal digits: (2,000.00) From the application menu, click Field Settings. For numeric fields you will see a Numeric Field Format column, use the drop down to select the numeric format you need.

Filter Via Record Selections:
Create hard-coded or user interactive filters based on specific criteria from your data. This feature allows users to filter the data to display only those records that match the selection criteria. Several options are available to create the relationship of the search, including "equal to, not equal to, is in the list, is in the range" and many more. Learn more.

Add Multi-Tenant Security:
m-Power applications can be secured to allow different users to access the same application, but see different results, based on the user login credentials. One example of this can be a report that contains records of customers for all the States in the USA, but the user will only work with the customers in his/her home State, via row level security m-Power can filter and display only the customers that the user is allowed to see. This technique allows you to fully implement scalable security solutions. Learn more.

Override/Customizable Error Messages:
All m-Power templates allow you to modify the default error messages. Most error messages are generic in describing the issue, maybe you need your users to see a more personalized or informative error message. From the application properties developers can change the error message without having to open the code source of the application. Learn more.

Call External Object Programs:
m-Power can handle your back-end business code too! The use of External Objects allows m-Power to tie into your custom coding easily, whether it is Java, SQL, or RPG. Learn more.
Back To Diagram

Saved Searches:
For end users running applications, there is a feature that allows them to save the search and come back to it later, saving them time and making it more efficient by saving multiple searches and switching between them with just a click. These searches can be found on the right upper corner of the running application by clicking Options then Saved Searches. Learn more.
Back To Diagram

Customize HTML with m-Painter:
m-Power ships with its own HTML editor. This tool, called m-Painter, allows you to modify the HTML code in a very easy way by using a WYSIWYG (What You See Is What You Get) editor, where all the graphical modifications are instantly visible. For the advance developers, there is a text editor mode too. You can access the HTML editor by clicking Presentation on the Application Menu. Learn more.
Back To Diagram

Control DB Join Type:
When joining tables you can set the join type of the application to be Left Outer Join or Inner Join. An inner join specifies that only records in the primary table with matching records in the secondary table will be displayed.
Back To Diagram

Add Row-Level Logical Fields:
m-Power allows you to create a logical field at the database level that is available to all applications. The options are Substring, Concatenation, or UDF (User Defined Function). By creating these files at the dictionary level, they are reusable across the entire dictionary, saving the developer time! Learn more.
Back To Diagram

Tablet & Mobile Output:
m-Power allows developers to create applications specifically for PC browser, Tablet, and Smartphone devices. For the user, this means that they can access the same report on their PC, tablet, and smartphone and see a completely different output on each that has been tailor-made for their device. For the developer, it means that they can create and maintain one single application that will create the proper output formats automatically. Learn more.
Back To Diagram

SmartLinks:
SmartLinks allow developers to easily link one application (Inquiry, Report, or Maintenance) to any other application, passing key data automatically. An example of this can be an Inquiry or a Report that links to a maintainer to update only an specific record and then redirect back to the list of records. By smartlinking applications m-Power makes it easy to link applications together to create smooth navigation between web applications. Learn more.

Ability to Ad-Hoc Sort on Any Column:
By clicking the up or down arrows next to the column name, Multiple Record inquiry allow end users to sort the data in ascending or descending order at runtime, based on any field from the application.
Back To Diagram

Ability to Ad-Hoc Filter on Any Column:
On the pagination bar you will find a button labeled "Selection", this feature allows users to search through records within the application. Here users can control how many records to display per page. Filter on specific fields by selecting a relationship, and the ability to input a value to search for. All of this from the web browser, at runtime.
Back To Diagram

Paginates Through Record Set:
The Multiple Record inquiry makes it easy to navigate through large number of records by displaying only 10 records per page and allowing users to use the navigation bar to move back and forward through pages. The amount of records displayed per page can be changed by simply clicking the Selections button.

Template Notes

Application Settings

Description: Allow developers to give their application a description.

Program Name: This will be the application’s name, by default m-Power uses the letter I (Inquiry) followed by a five digits number. Also by default, for every new application m-Power will look at the largest number in use and increase it by 10, you can manually change this number.
Note: the number must be unique in the Data Dictionary.

Select Only Matching Records: When joining to other tables, you have the option to create a Left Outer Join or and Inner Join. Selecting Yes (inner join) will include only matching records from the joined table. A simple example of this could be a Sales History table that links to a Product Master table. Now imagine some products have been discontinued and subsequently removed from the Product Master table. With an outer join, the discontinued products will still be reported. However, with an inner join, records without matching records in the product master will be omitted from the result set.

Template: You can select a template by scrolling left or right through the available templates. The templates define the general layout and functionality of the resulting application. This section will list all the available retrieval templates; you will see a small screenshot of what that template looks like at runtime. Learn more about templates.

Compile Options: Selecting the Advanced Search Row will display an input box for every column that will allow users to filter based on a value, in that column/field. Selecting Advanced Search Dialog will display a button labeled "Selections" clicking this button at runtime; will open a popup window where users can create multiple filters for multiple fields.

Data Selection

Here you will see/modify the table you have selected for your application. Here you can create or modify joins to other tables as well.

Sequencing

Here you can select the field that your application will sequence by; you can have multiple sequence fields. You can re-order the sequences to fit your application’s needs. Retrievals also have the power to allow end users to Ad-Hoc sort at runtime on a specific field or column. Learn more.

Field Settings

Here you will find the settings for all the fields in the application. The options are:

Delete: You can delete fields by clicking the checkbox and clicking Accept. If a field has a red circle with a cross line, that means that the field is being used somewhere else in the application (sequence, calculation, etc.), and, due to this dependency, is not available for deletion.
Note: Deleting a field will remove the field from the application only, the table will be unchanged.

Field Name: This is the same name the field has in the table.

Table: The name of the table where that field exists.

Field Description: This is the text that will appear in the column header for that field, you can modify this field to suit your needs. This field will populate with the field description from the table by default, but it can be customized at the application level.

Display: A radio button allows developers to display or hide the field from the output page. There may be situations where a field is needed for calculation purposes, but the field does not need to be displayed at runtime.

Length: Here you can modify the length of the field. m-Power will only allow developers to shorten the length of the field, shortening a fields length will truncate its data. For example, if a field is 10 alpha and it is changed to 5 alpha, now only the first 5 characters will be displayed. The same principle applies to a numeric field, if a numeric field is 8 digits long; changing it to 4 digits long will only display the first 4 digits, and leave out the rest of digits.

Decimals: For numeric fields, you can modify the amount of decimal digits. A numeric field will have the option of changing its decimal length, alpha fields does not have a decimal option, developers can use this as an indicator to check if a field is a numeric or character type.

Numeric Format Code: For numeric fields, you can modify the way the numbers will display, this includes displaying decimals or not, how to display negative numbers, etc. Multiple formats are built in for developers to use, shall you need a different format code, m-Power allows developers to create their own User Defined Format codes; these codes will add logic for common types of fields such as: Currency, Time, or Dates. Accessing the User Defined Format Codes from the Admin section will also allow developers to modify current codes. Learn more.

Note: Do not confuse the User Defined Format Code with the User Defined Functions (UDF). The latter is a feature that allows developers to create or incorporate programing functions into m-Power. Learn more about UDF's.

User def: This feature has being deprecated

Record Selections

Record Selections can be created over fields from both primary as well as secondary tables. These are the options:

Field: A drop down allows you to select the field you want to filter on.

Relation: A drop down allows you to select a relationship for the filter.

Value: This is the value to compare against. The options are:

Constant Value: A constant value allows you to hard-code any given value into a selection. This value cannot be modified by the end-user at run–time.

Application Field Value: Developers have the option of comparing a value from one field to a value from another field within the same record.

And/Or: When creating multiple record selections, you have the option to set them as "and" or "or" Example: selection A "and" selection B will display only records that match both selections. Selection A "or" selection B will display records that match one or both selections. Learn more.

Calculations

Calculations are a very powerful feature of m-Power; with calculations, developers can create logical fields that will apply to the current application only. This can be used to include SQL code in a field, such as cast a numeric field as character, create date conversions, inserting the current date and time, and much more. Learn more.

External Objects

This feature allows developers to connect m-Power application with their current business logic, or to extend m-Power capabilities by allowing developers to write their own Java, RPG, or SQL programs, and integrating these programs into the applications. m-Power utilizes "locations" to connect the external objects, these locations vary depending on what the external object does and when it should be executed. The following locations are supported in this template: Learn more.

*CALCOBJ Used when parameter calculations are present in the application. The external object is called after each row is processed.
*STRADVSCH This location has been deprecated.
*ADVRECSEC This location has been deprecated. Learn more about Row Level security.
*READRECRD This location will call the external object after each record is processed.
*SELECTFLT This location has been deprecated. Learn more about creating dropdown lists using m-Painter.

SmartLinks

SmartLinks allow developers to easily link one application (Retrieval, Report, or Maintenance) to any other application, passing key data automatically. The benefits of this are many, including: creating applications that will allow developers to link a Retrieval to a Maintainer in order to update an specific record passing key parameters automatically. Create a Hover-Over window; create a popup dialog, and many more. By, passing parameters automatically when creating a link in m-Painter, SmartLinks save the developer time by simplifying the process. Learn more.

Note: After performing any changes in the above sections, the application must be recompiled for the changes to load. If the changes are to be displayed at runtime, then the Presentation Layer code (HTML) must be overwritten when recompiling the application.

Runtime Walkthrough

Multiple record inquiries are designed to display information in a simple, user-friendly design. By default, ten records will be returned to the screen. End-users can sort on individual fields within the application by clicking on the arrows next to the field names. Alternatively, end-users can search for records. This can be done through the Advanced Selection dialog. To search for a record, simply enter a value and the appropriate relationship. Then click ‘OK’. Also notice that end users can designate the number of rows to display per page through the selections button. End-users can page through the data by clicking the single arrows, or skip to the end or beginning of the data by clicking the double arrows. The default settings can all be controlled by the developer within the m-Power interface.
