/**
* pragmaGetTest.rex
*
* One of the non-standard SQL features of SQLitet is the PRAGMA statement.
*
* "The pragma command is specific to SQLite and is very unlikely to be
* compatible with any other SQL database engine."
*
* PRAGMA statements are executed like any other SQL. Some pragmas return
* tables, some do not. Unknown pragmas are ignored by SQLite. Some pragmas
* set values, some return a single value.
*
* Because of these differences, ooSQLite wraps the execution of a pragma in
* the pragma() method. You would not have to use the pragma() method, you
* could instantiate an ooSQLiteStmt and execute the SQL like any other SQL.
*
* This test issues pragmas that return a single value.
