The Create/Modify Trigger wizard allows you to set the properties for new ABL triggers or modify the properties of existing ABL triggers in an OpenEdge database.
| Table | A valid table name from a list of tables in the PUB schema. |
| Column Trigger | When the option is selected, displays all columns for the selected table in the Column combo box. The Event field is set to ASSIGN (since that is the only event for a column trigger). |
| Column | A list of the columns in the selected table. |
| Event | A list of available trigger types including: CREATE, DELETE, WRITE, FIND, REPLICATION-CREATE, REPLICATION-DELETE, REPLICATION-WRITE, and ASSIGN (for column triggers). |
| Create new trigger file | When the option is selected, the system creates a new file by the system in a specified project and folder. You specify the project and folder in the New File dialog, which appears when you select the Browse button. When you specify the project and folder, they appear in the read-only Parent Folder field. The read-only Propath field displays the PROPATH setting for the selected OpenEdge project. |
| Attach existing trigger | When the option is selected, the system attaches a specified trigger to this trigger. You select an existing trigger in the Trigger Selection dialog box, which appears when you select the Browse button. After you select a trigger, the trigger file name appears in the read-only File Name field. |
| Override | When the option is selected, users can redefine and overwrite triggers at run time. |
| Check CRC | When the option is selected, the system checks the validity of the trigger at run time. CRC (Cyclical Redundancy Check) is an algorithm that verifies the integrity of executables. It compares a stored number in the executable with a number calculated from the schema. If the numbers do not match (after a schema change, for example), the executable must be recompiled. |
