The While Loop action enables you to specify an action or group of actions that the Integration Service will continue to execute sequentially as long as the specified condition continues to be satisfied.

You can configure the following properties for the While Loop action:

Action

• Name: Specifies the name of the action. If desired, you can replace the default name by typing a new name in the field.

• Description: Allows you to save a description for the action.

• Run While: Allows you to specify for how long you want the Integration Service to continue to execute the actions in the group.

  • Always: Specifies that the Integration Service will continue to run each action in the group until a Stop or Go To action within the group is executed.

  • Never: Specifies that the Integration Service will not run the actions in the group when it runs the integration.

  • Conditionally, based on variable: Specifies that the Integration Service will continue executing the actions in the group for as long as the selected variable meets the specified condition. Use this option in situations where there is only one condition that determines whether or not the actions will run. Once you have enabled this option, you can create the conditional statement in the input box provided.

    Input box controls

    • Variable: Enter the variable that you want to use for the conditional statement. Alternatively, expand the dropdown list and select a recently used variable, or select Variables or More Variables to open the Insert Variable dialog.

    • [Relational Operator]: Specifies the relational operator to use for the conditional statement. Click the existing operator to open a list of additional operators, and select the one you want to use. For more information, refer to Relational Operators. The operators available in the list depend on whether you have selected Text or Decimal for the Type option.

    • Value: Specifies the value(s) to use for the conditional statement. Some operators, such as Is null and Is not null, do not require a value to be specified. In these situations, the Value field is not available.

    • Type: Specifies whether the conditional statement is evaluating a text or decimal value.

       

  • Conditionally, based on expression: Specifies the conditions under which the Integration Service will continue executing the actions in the group. Use this option for situations that require more than one conditional statement. Once you have enabled this option, you can create the conditional expression in the input box provided by creating the desired conditional statements. You create and edit your conditional expression on the Tree View tab. Click the Text View tab to see a read-only text view of the conditional expression.

    • [Conditional Joiner]: Specifies the conditional joiner for the conditional statements within the group. The default conditional joiner is And.

      Click the existing conditional joiner to access a menu that allows you to configure your conditional expression in one of the following ways:

      • Select a different conditional joiner: The menu options include a list of conditional joiners. Select the conditional joiner you want to use for the conditional statements. For more information about the supported conditional joiners, see Conditional Joiners.

      • Add Condition: Click to add another conditional statement to the current group.

      • Add Group: Click to add a sub-group of conditional statements to the current group.

      • Remove Group: Available in the menu when the menu has been opened from a sub-group. Click to delete the sub-group.

      • Clear All: Available in the menu when the menu has been opened from the top-most group. Click to delete all conditional statements (including sub-groups).

    • : Visible just to the right of each conditional joiner in your expression. Click to add a conditional statement to the group associated with that joiner.

    • :  Visible when you position the cursor over an existing conditional statement. Click to delete the conditional statement.

    • Variable: Enter the variable that you want to use for the conditional statement. Alternatively, expand the dropdown list and select a recently used variable, or select Variables or More Variables to open the Insert Variable dialog.

    • [Relational Operator]: Specifies the relational operator to use for the conditional statement. Click the existing operator to open a list of additional operators, and select the one you want to use. For more information, refer to Relational Operators. The operators available in the list depend on whether you have selected Text or Decimal for the Type option.

    • Value: Specifies the value(s) to use for the conditional statement. Some operators, such as Is null and Is not null do not require a value to be specified. In these situations, the Value field will be hidden.

    • Type: Specifies whether the conditional statement is evaluating a text or decimal value.

User Account

• Inherit from parent action: When enabled, the action inherits the user account credentials specified on the Actions property page. Alternatively, if the action is part of a Group action, it will inherit the user account credentials specified on the immediate parent Group action’s property page.

• Specify user credentials: When enabled, the action runs using the credentials specified.

Error Handling and Diagnostics

• Ignore errors and continue running actions: When enabled, specifies that if the action fails, the remaining actions will continue to run.

  When this property is not enabled and the action fails, the resulting behavior depends on the following scenarios:  If you have specified Sequentially for the Execute Actions property of the selected action's hierarchical Actions or Group property page, no further actions within that group are executed. If you have specified In Parallel for the Execute Actions property of the action's hierarchical Actions or Group property page, the actions within that same group are not affected; the errors are ignored and the other actions within the group are executed. If the selected action is within a Group action, no actions outside of that Group action are affected.
