How to Work with Processes > Working with the Local Database Processes Group

Process Purpose

The "Local Database Free SQL Statement" process is used to execute free SQL statements to a data source in a specific Host server.

When you add a process, you are required to define its settings. This occurs in the process's properties window which is displayed automatically after having added the "Local Database Free SQL Statement" process. This properties window is divided into two tabs - "General" and "Advanced".

If any subsequent edition is required, double-click the process to open its properties window and enter the necessary modifications.

"General" tab

Fill in the following options:

SQL Statement
Define the SQL statement. You can enter it and click to include variables anywhere in the statement. Ex: Select * from table where field = '&A1'
Response
Wait for Returned Value	Check this option to wait for an answer from the database regarding the SQL statement and to enable the "Store in Variable" option.
Store in Variable	Click to select the variable that will receive the return value. You can retrieve up to 80 values at once. See To Select/Create a Variable.

Use the editing icons to the right of the table to move the rows up and down and to delete or add more rows.

Proceed to the "Advanced" tab.

"Advanced" tab

Fill in the following options:

Store Number of Selected Record(s) in Variable
Variable	Click to select the variable that will receive the number of selected records. See To Select/Create a Variable.
Store Number of Affected Record(s) in Variable
Variable	Click to select the variable that will receive the number of affected records.
If No Record(s) Selected
Go to	Select a target location from the drop-down or list, in case no records are selected. See Detail of a window below. When defining a screen as a target destination (ex: via a “Go to” process), you CANNOT use variables to specify the name of that target screen. You must select the intended screen from the available drop-down/list.
If No Records Affected
Go to	Select a target location from the drop-down or list, in case no records are affected. See Detail of a window below. When defining a screen as a target destination (ex: via a “Go to” process), you CANNOT use variables to specify the name of that target screen. You must select the intended screen from the available drop-down/list.
If SQL Error
Go to	Select a target location from the drop-down or list, in case an "SQL Error" occurs. See Detail of a window below. When defining a screen as a target destination (ex: via a “Go to” process), you CANNOT use variables to specify the name of that target screen. You must select the intended screen from the available drop-down/list.

Depending on the used SQL statement, the returned condition will either include the selected or the affected records.

Ex: When using an "UPDATE " SQL statement, the "Selected Records" return condition will not be used.

Detail of a window:

"S:Menu" is a screen included in the same program as the process.

"R:Routine_1" is a routine included in the same program as the process.

If required, use the icons on the upper right corner of the properties window:

Click it to create a new table in a local database. See Creating a Table.

Click it to test SQL scripts. See To Test SQL Scripts.

Use the icon to attach any relevant notes to this process. Click it and enter your notes in the resulting text box. These notes will be displayed in the corresponding "Actions" tab or "Process" window (in the "Notes" field) and in the "Developer Report".

After filling in the required options, click to conclude or to abort the operation.

The added process is displayed in the corresponding "Actions" tab or "Process" window.

If you want to use a label as a target destination, you can use the "Auto-Label" mechanism. This alternative to the "Set Label" process allows you to create a label in the properties window of a process - specifically, in the fields used to define target destinations (ex: the "If Error..." type fields). See To Automatically Create a Label.

Use the right-click in MCL-Designer's input boxes to access some related options as well as the general "Cut", "Copy"; "Paste"; "Search" actions (active/inactive according to the current context).

Ex: If you right-click the "Variable" input box (included in a "Conversion's" properties window), you are provided with general editing/search actions and other more specific options such as "Variable Select" (see "Variable Select"); "Variable Insert" (see "Variable Insert"); "Insert Special Character" (see To Insert Special Characters into a Control's Text Input Field) and "Localization Select" (see Localization List).

If you right-click another input box, it may provide other possibilities.
