Add / edit / delete data source
All added data sources should be tested for connectivity by clicking the Test Connection button before adding to ensure connectivity.
The data sources are divided into query data sources / non-query data sources . The query data source appears only within the scope of the query data source with fine-grained permissions. The same goes for non-query data sources. (The query and execution data source should be split into two to ensure that the online execution data source will not affect the business due to the slow query sql)
After this category is added cannot be modified by editing , please add it carefully.
