SQL statements are generated by AECOsim Building Designer each time you use certain database tools and key-ins. For example, AECOsim Building Designer generates a SQL INSERT statement when you use the Attach Active Entity tool with Linkage Mode set to New.

By default, AECOsim Building Designer immediately commits SQL statements to the database software. In an alternate mode, AECOsim Building Designer commits statements only when your input necessitates the addition of a row to a database table. The process of adding rows requires the database software to lock tables, and commitment is required to release those locks. The alternate mode can be useful when it is desirable to be able to undo uncommitted SQL statements.
