Instead of specifying a clause parameter with a particular Item ID, this parameter can also be specific with 'X'. The result of placing an X for a parameter, is that a single TQL statement is by mutliple TQL statement, one with each Item ID for that Clause Parameter that can be found in the project data. Internally, the resulting TQL statements are placed in a single array and the result will be an array of TQL results.

For example, the TQL statement

SELECT_NAME_WHERE_NEIGHBORHOOD_IS_X

is internally replaced with a list of TQL statements, separated by comma's,

SELECT_NAME_WHERE_NEIGHBORHOOD_IS_0, SELECT_NAME_WHERE_NEIGHBORHOOD_IS_2, SELECT_NAME_WHERE_NEIGHBORHOOD_IS_3, SELECT_NAME_WHERE_NEIGHBORHOOD_IS_5

Its result will be a list of names, separated by comma's, for example:

"Mayfair", "Soho", "Marylebone", "Hyde Park"

Clause Parameters

The X value can be used in the following TQL Clause parameters:
