How to include the missing columns when using an SOQL statement

How to include the missing columns when using an SOQL statement

The following concern applies to previous releases (before 1.9). Currently, all columns from the SOQL are automatically created, but in some cases, the data type of the column might not be retrieved from the results and a WSTR 250 would be assumed.

The Salesforce service only returns fields containing data. If there is no data for a specific field, no data is returned. Therefore, it is impossible to set up the appropriate field and field type. There are 3 options to include the missing columns:

Option 1
This option will work fine for SOQL statements without relationships. For statements with relationships, see the other options below.

1. Set the InputType to 'Object'. Select the object from which you want to retrieve data.
2. Go to the 'Column Mappings' tab and press 'Refresh' to reload the object's columns.
3. Set the InputType to ‘Statement’ and specify your statement. Do not refresh the columns in the 'Column Mappings' tab.
4. If you want to remove columns you don't need, go to the 'Column Mappings' tab and remove the mappings you don't need.

Option 2

1. Set up a temporary Salesforce record and the required relationship data.
2. Open the 'Salesforce Source' component setup dialog and specify the SOQL statement retrieving the temporary record data.
3. Refresh the 'Column Mappings' tab. All needed column metadata should now be included.
4. Go back to the Salesforce setup window and remove the temporary record and all other unneeded data.

Option 3
This option requires manual definition of the missing columns.

1. Go to the 'Input and Output Properties' tab.
2. Go to 'Salesforce Source Output' -> 'External Columns'.
3. Press 'Add Column'.
4. Specify the column name and type. Make sure the name is specified properly with the appropriate structured definition.
