KirSQLite - Flex AIR Database Manager: Part 45

In this tutorial we'll work on the trigger creation window.

When the user clicks "New trigger", a pop up shows up with options of creating triggers.

The syntax of Trigger creation can be found on the official site.

Before we create the window with all the content in it, let's declare a bunch of variables.

We'll need 2 empty ArrayCollections - triggerTableColumns and triggerTables. These ones will be used for storing all available columns of the selected table, and all the available tables of the selected database.

<mx:ArrayCollection id="triggerTableColumns">
</mx:ArrayCollection>
<mx:ArrayCollection id="triggerTables">
</mx:ArrayCollection>

We'll also need 2 already filled ArrayCollection objects - triggerKeywordOptions and triggerActionOptions. The options for trigger keywords are "BEFORE ", "AFTER ", "INSTEAD OF " and blank " ". Notice how there's a whitespace after each of the keyword. That will come in handy later.

The options for trigger actions are "DELETE ", "INSERT ", "UPDATE ".

<mx:ArrayCollection id="triggerKeywordOptions">
<fx:String>BEFORE </fx:String>
<fx:String>AFTER </fx:String>
<fx:String>INSTEAD OF </fx:String>
<fx:String> </fx:String>
</mx:ArrayCollection>
<mx:ArrayCollection id="triggerActionOptions">
<fx:String>DELETE </fx:String>
<fx:String>INSERT </fx:String>
<fx:String>UPDATE </fx:String>
</mx:ArrayCollection>

Now we'll create the TitleWindow object. Call it triggerWindow. Set its close event handler to closeTriggerWindow.

<mx:TitleWindow id="triggerWindow" title="Add a new trigger" close="closeTriggerWindow();" showCloseButton="true" width="400">
<s:VGroup paddingTop="4" width="100%">

Here are all the controls we'll have to include:

1) A TextInput called "triggerName" where the user will enter a name for the trigger

<s:HGroup width="100%" verticalAlign="middle">
<s:Label>Trigger name: </s:Label>
<s:TextInput id="triggerName" width="100%" />
</s:HGroup>

2) A ComboBox "triggerDatabase" that the user will use to choose the database that the trigger will be created in. This is also the database the table is located in. Set its dataProvider bound to {databaseData} and change event handler to updateTriggerTables().

<s:HGroup width="100%" verticalAlign="middle">
<s:Label>Trigger database: </s:Label>
<mx:ComboBox editable="false" id="triggerDatabase" dataProvider="{databaseData}" labelField="name" change="updateTriggerTables();" />
</s:HGroup>

3) Another ComboBox, this time for table selection. Call it "triggerTable" and bind to {triggerTables}. Set the change event listener to updateTriggerTableColumns():

<s:HGroup width="100%" verticalAlign="middle">
<s:Label>Table: </s:Label>
<mx:ComboBox editable="false" id="triggerTable" dataProvider="{triggerTables}" labelField="name" change="updateTriggerTableColumns();" />
</s:HGroup>

4) Next is a ComboBox that is used to choose one of the keywords from triggerKeywordOptions ArrayCollection. Set its id to "triggerKeyword" and dataProvider to {triggerKeywordOptions}:

<s:HGroup width="100%" verticalAlign="middle">
<s:Label>Keyword: </s:Label>
<mx:ComboBox editable="false" id="triggerKeyword" dataProvider="{triggerKeywordOptions}"/>
</s:HGroup>

5) A "triggerAction" ComboBox bound to {triggerActionOptions}:

<s:HGroup width="100%" verticalAlign="middle">
<s:Label>Action: </s:Label>
<mx:ComboBox editable="false" id="triggerAction" dataProvider="{triggerActionOptions}"/>
</s:HGroup>

6) A List object that is enabled when the "UPDATE" keyword is used called "triggerColumnList". DataProvider bound to {triggerTableColumns}. Using this control the user will be able to select one or multiple columns to listen for updates on. Make sure its allowMultipleSelection property is set to true:

<s:Label>Optional: UPDATE column(s): </s:Label>
<s:List enabled="{triggerAction.selectedIndex==2}" allowMultipleSelection="true" width="100%" height="100" id="triggerColumnList" dataProvider="{triggerTableColumns}" />

7) A CheckBox with an id "triggerForEachRow". Will enable "FOR EACH ROW" when ticked:

<s:CheckBox id="triggerForEachRow" label="FOR EACH ROW" />

8) An optional clause WHEN will require a TextArea. Call it "triggerWhen":

<s:Label>Optional: WHEN</s:Label>
<s:TextArea id="triggerWhen" width="100%" height="50" />

9) A rather big TextArea surrounded by "BEGIN" and "END" clauses. Call it "triggerBegin":

<s:Label>BEGIN</s:Label>
<s:TextArea id="triggerBegin" width="100%" height="100" />
<s:Label>END</s:Label>

10 ) Finally, a button "Add trigger" with click event handler doNewTrigger():

<s:Button click="doNewTrigger();" label="Add trigger" width="100%" />

</s:VGroup>
</mx:TitleWindow>

Full TitleWindow code:

<mx:TitleWindow id="triggerWindow" title="Add a new trigger" close="closeTriggerWindow();" showCloseButton="true" width="400">
<s:VGroup paddingTop="4" width="100%">
<s:HGroup width="100%" verticalAlign="middle">
<s:Label>Trigger name: </s:Label>
<s:TextInput id="triggerName" width="100%" />
</s:HGroup>
<s:HGroup width="100%" verticalAlign="middle">
<s:Label>Trigger database: </s:Label>
<mx:ComboBox editable="false" id="triggerDatabase" dataProvider="{databaseData}" labelField="name" change="updateTriggerTables();" />
</s:HGroup>
<s:HGroup width="100%" verticalAlign="middle">
<s:Label>Table: </s:Label>
<mx:ComboBox editable="false" id="triggerTable" dataProvider="{triggerTables}" labelField="name" change="updateTriggerTableColumns();" />
</s:HGroup>
<s:HGroup width="100%" verticalAlign="middle">
<s:Label>Keyword: </s:Label>
<mx:ComboBox editable="false" id="triggerKeyword" dataProvider="{triggerKeywordOptions}"/>
</s:HGroup>
<s:HGroup width="100%" verticalAlign="middle">
<s:Label>Action: </s:Label>
<mx:ComboBox editable="false" id="triggerAction" dataProvider="{triggerActionOptions}"/>
</s:HGroup>
<s:Label>Optional: UPDATE column(s): </s:Label>
<s:List enabled="{triggerAction.selectedIndex==2}" allowMultipleSelection="true" width="100%" height="100" id="triggerColumnList" dataProvider="{triggerTableColumns}" />
<s:CheckBox id="triggerForEachRow" label="FOR EACH ROW" />
<s:Label>Optional: WHEN</s:Label>
<s:TextArea id="triggerWhen" width="100%" height="50" />
<s:Label>BEGIN</s:Label>
<s:TextArea id="triggerBegin" width="100%" height="100" />
<s:Label>END</s:Label>
<s:Button click="doNewTrigger();" label="Add trigger" width="100%" />
</s:VGroup>
</mx:TitleWindow>

Now let's add some code for the functions.

In the existing empty newTrigger() function, add and center this pop up, set enableEverything to true.

Set default value for triggerName.

Load databases into databaseData to use in triggerDatabase.

Load tables by calling updateTriggerTables():

private function newTrigger():void {
PopUpManager.addPopUp(triggerWindow, this);
PopUpManager.centerPopUp(triggerWindow);
enableEverything = false;
// set default name
triggerName.text = "UntitledTrigger";
// load databases
databaseData = new ArrayCollection([]);
for (var i:int = 0; i < dbData..db.length(); i++) {
var dbid:String;
if (dbData..db[i].@numid == 1) dbid = "main";
if (dbData..db[i].@numid != 1) dbid = "db" + dbData..db[i].@numid;
databaseData.addItem( { name:dbData..db[i].@name, did:dbid } );
}
// load tables
updateTriggerTables();
}

The updateTriggerTables() function is also called when the user selects a different database. Here we load tables of the said database and put them in triggerTables. Then we call updateTriggerTableColumns():

private function updateTriggerTables():void {
triggerTables = new ArrayCollection([]);
connection.loadSchema(null, null, triggerDatabase.selectedItem.did);
var schema:SQLSchemaResult = connection.getSchemaResult();
for (var i:int = 0; i < schema.tables.length; i++) {
triggerTables.addItem( {name: schema.tables[i].name} );
}
// load columns
updateTriggerTableColumns();
}

UpdateTriggerTableColumns() is also called when the user chooses a different table. Here we load columns and put them in triggerTableColumns:

private function updateTriggerTableColumns():void {
triggerTableColumns = new ArrayCollection([]);
connection.loadSchema(SQLTableSchema, triggerTable.selectedItem.name, triggerDatabase.selectedItem.did);
var schema:SQLSchemaResult = connection.getSchemaResult();
for (var i:int = 0; i < schema.tables[0].columns.length; i++) {
triggerTableColumns.addItem(schema.tables[0].columns[i].name);
}
}

In closeTriggerWindow() we remove the pop up and disable everything:

private function closeTriggerWindow():void {
PopUpManager.removePopUp(triggerWindow);
enableEverything = true;
}

In doNewTrigger() we close the window for now:

private function doNewTrigger():void {
closeTriggerWindow();
}
