SqlSelect()

Previous Next

Creates an info window with the name specified in a SELECT statement. Examples of where this function can be used include startup, button, decision and dialog actions.

Syntax

SqlSelect( { select-statement | method-call }window )

 

Select-statement is the query underlying the info window to be created. Alternatively, you can specify a method-call such as FORMULA() or an ObjectName.propertyName() call that returns the current value of a property.

The UNION set operator can NOT be used in select-statement.

The optional window identifies the window class of which an instance is to be created:

If an info window with this name is available in the ESI file, it is used.

Otherwise a default info window is created.

If window is not specified, the Object Name Plural of the main table of the underlying query is used.

Example 1

SqlSelect( 'SELECT destination, tour_type FROM TOUR', 'Destinations' )

 

If you want to refer to a certain value produced by an existing global variable, or from a certain text box or column, surround it with double quotes and start with a colon, as shown in examples 2 and 3:

Example 2

SqlSelect( 'SELECT destination, tour_type FROM TOUR where :"Global.MyVariable"', 'Destinations' )

 

Example 3

SqlSelect( 'SELECT destination, tour_type FROM TOUR where destination = :"Variables.Text_Box_1()"', 'Destinations' )

 

In a Yes or No Action Decision, you cannot define SQLSelect() statement with a placeholder referring directly to the value retrieved by its Decision SQL. Instead, first transform the output of the Decision SQL to a global variable using ResourceFileUpdate(). Then, define SqlSelect() referring to the new value of the global variable, as shown in example 4:

Example 4

(Decision SQL:)

Select destination from tour where tour_type = 'SPORTS'

 

(Yes or No Action:)

ResourceFileUpdate( 'MyFavoriteDestination: ' ||:1 )

SqlSelect( 'SELECT destination, tour_type FROM TOUR where destination = :"MyFavoriteDestination"', 'Destinations' )
