Because many SQL build classes need to establish MySQL connections, but sometimes we just want SQL statements, do not want to connect to the database, so it is particularly important to have a pure SQL build tool.
Current SQL building tools are based on ThinkPHP 3.2, and most SQL operations are the same as ThinkPHP 3.2 model operations.

Using this tool, you do not need to configure any database information, and you will not establish MySQL connections.
The Sql class supports the singleton creation of objects Sql:: getInstance ();, or directly new Sql ().
For detailed instructions, see demo.php, or ThinkPHP 3.2 operation model instructions

Validation of database fields is not supported. [ Table structure information cannot be obtained without establishing MySQL connections, and therefore cannot be validated ]
Objects are not supported to create new data objects, that is, there is no create method, only in the form of arrays.
The cache method in coherent operations is not supported.
Calling the fieldmethod before the add method does not support field filtering.
Calling the fieldmethod before the save method does not support field filtering, but does support data filtering.
Deleting data does not support sql-> delete ('1,2,5'); This usage means that the deletemethod cannot take parameters
The select function does not support parameters
Mapping tables to classes and records to objects is not supported
Field mapping is not supported
The relation method in coherent operations is not supported
