Limitation

Description

Some SOQL queries are not supported for the guess schema and guess query features of tSalesforceInput.
  • the SOQL query using the aggregate function
  • the SOQL query using the TYPEOF expression
  • the SOQL query using alias
  • the prefix in the SOQL query is the same as the module name after FROM

    For example, SELECT Account.Name, (SELECT Contact.LastName FROM Account.Contacts) FROM Account is not supported, while SELECT Name, (SELECT LastName FROM Contacts) FROM Account that performs the same function is supported.

  • the SOQL query with multiple modules after FROM

    For example, SELECT Contact.Firstname, Account.Name FROM Contact,Contact.Account is not supported. However, the child-to-parent and parent-to-child relationship queries are supported, so this query can be improved to SELECT Firstname, Account.Name FROM Contact.

  • the SOQL query using toLabel()
  • the field with the underscore character '_' in its name
Java PSU is not supported. Talend is only supported on Java CPU Versions, not Java PSU.

Some users reported problems using Talend Studio with Java PSU versions (such as jdk8_u92), but when reverting to a Java CPU Version (such as jdk8_u91) the problem was resolved.

Collation limitation with Access Since 6.0, the Access components in Talend Studio support only the General collation mode.

OAuth mode in the Salesforce wizard

To establish a Salesforce connection using OAuth2 authentication, you need first to execute a Talend Job to obtain your token file and then initialize it in the wizard.

Issue

Workaround

If Talend Administration Center works in clustered mode (two Talend Administration Center instances located on different physical servers but connected to the same database), context values may not be available in task execution details. It is recommended to use shared folder in Job Conductor configuration which are available for all works in cluster mode.
