Specifies the SQL condition corresponding to the WHERE part of a SELECT statement which would return only 1 row (the expression of the primary key).
For example for a table created as "CREATE TABLE mytable (part1 int NOT NULL, part2 string NOT NULL,
name string, PRIMARY KEY (part1,
part2))", and if pmodel corresponds to the execution of the "SELECT name, part1, part2 FROM mytable", then the sensible value
for sql_where would be "part1 = ##-1::int AND part2 = ##-2::string" because the values of the 'part1' field are located in
pmodel's column number 1 and the values of the 'part2' field are located in pmodel's column number 2 and the
primary key is composed of (part1, part2).
For more information about the syntax of the parameters (named "##-1::int" for example), see the GdaSqlParser documentation, and set_modification_statement.
