SQLConnectionMBS.CancelAllCommands
Function:
Cancel all commands for the connection.
Notes: This loops over the list of commands associated with this connection and calls Cancel on them.
| Type | Topic | Plugin | Version | macOS | Windows | Linux | Console & Web | iOS |
| method | SQL | MBS SQL Plugin | 18.4 | Yes | Yes | Yes | Yes | No |

SQLConnectionMBS.Commands as SQLCommandMBS()
Function:
Queries list of all command objects related to the connection.
| Type | Topic | Plugin | Version | macOS | Windows | Linux | Console & Web | iOS |
| method | SQL | MBS SQL Plugin | 18.4 | Yes | Yes | Yes | Yes | No |
SQLConnectionMBS.Commit
Function:
Saves any changes and ends the current transaction.
Notes:
Use Commit method to write transaction changes permanently to a database. It commits the work of all commands that associated with that connection.
All changes to the database since the last commit are made permanent and cannot be undone. Before a commit, all changes made since the start of the transaction can be rolled back using Rollback method.

SQLConnectionMBS.Connect(DBString as string, UserID as string, Password as string, client as Integer = 0)
Function:
Opens the connection to a data source.
Example:
Notes:
Using the Connect method on a SAConnection object establishes the physical connection to a data source. After this method successfully completes, the connection is live and you can issue commands against it and process the results.
If you use the default value of Client parameter, you should set Client before using Connect.
To check whether a connection established use isConnected method. To check whether a connection is brocken or not use isAlive method.

For IPv6 we changed plugin to use , instead of : for the port separator. So please use , to separate port from IP or host.
For Firebird, if you connect to a database and you have 32/64bit mismatch, you get error number 3.
