The SELECT
statement for TQL provides a means of obtaining data of a session.
The 'Select' statement is consists of the SELECT
word followed by a Selection type and the word WHERE
. Depending on the Selection Type one or more clauses can be added. Clauses are separated with the AND
word. All of these parts are separated by an underscore _
.
An example of a TQL select statement is: SELECT_LOTSIZE_WHERE_CATEGORY_IS_SOCIAL_AND_STAKEHOLDERTYPE_IS_MUNICIPALITY
. In this example, SELECT_LOTSIZE_WHERE
is the statement. CATEGORY_IS_SOCIAL
is the first clause, and STAKEHOLDERTYPE_IS_MUNICIPALITY
is the second clause. It would return all the land area taken up with social housing, which is also owned by a municipal stakeholder.
