Drupal uses db_query_range() for the reason that not all databases support LIMIT,
can you name a few?
回答1:
DB2, MSSQL, Oracle, and Informix all do not support LIMIT. As a matter of fact, it's not in the SQL standard. (The standard one is "FETCH FIRST" indeed)
Here is a good source for SQL comparisons: http://troels.arvin.dk/db/rdbms/#select-limit
回答2:
Microsoft SQL Server does not support LIMIT. It supports the TOP statement which can be used to accomplish similar things. The primary limitation with TOP is the inability to specify an offset.
回答3:
ms sql, oracle.
and actually LIMIT doesn't exists in ANSI SQL '92 which all modern databases should follow. so currently it's just an unnecessary extension/syntactic sugar/specific sql dialect
回答4:
DB2, Oracle, and MS SQL Server do not support the LIMIT clause.
Google for <database name> LIMIT, and you'll get to know the equivalent supported clause for that database, or whether LIMIT itself is supported.
回答5:
On the flip side, ANSI-92 SQL provides the ROW_NUMBER() window function for achieving this, which is supported on many databases. See SELECT (SQL) on Wikipedia.
