You is DataSnap server connection way or the other,

On the server side, if it is DataSnap be established through SQL accept upload data method,

In this way, the client can pass this method is called, upload the data to the table, such as: DataModule1. SocketConnection1. AppServer. MyQuery (SQL, err);

CodePudding user response:

If just insert the information in the edit1 database,
Use the TADOQuery, joining together the simplest SQL statements,

However, I see you stick figure,
Suppose you want to according to the results in the DBGrid,
If so, you have to TADOQuery using a simple SQL Select statement,
Such as SELECT * from TableName where 1 & lt;> 1
In order to obtain an empty data set,
Then, use the TADOQuery append, post to insert database,
