Content of the fix

I have found a security problem. Variables should be given directly to the cursor instead of writing them to the SQL. This prevents SQL injections.

By changing the avoidance of sql injection, the function “get_sql()” now returns “?” at the points where variables were before.

To get the variables back, there is now “values_for_execute”, which contains the variables in the correct order. The variables are returned in the type as they are stored. String as string, integer as integer, datetime as datetime...

Example

• conn.table().update().values_for_execute
• conn.table().select().values_for_execute

The variables are used in the statements where I suspect the possibility of SQL injection.

• Setting variables
• Where to query (conditions)

Setting keys or table names, for example, is normally not something a user should do, so they are written to SQL as normal.

I learned a lot while working on other projects. This has given me some knowledge about security. So I thought it was right to apply this to old projects as well.
