Mole Unless stated otherwise, the principals illustrated are the same for all message domains. When you create a message flow, you include input nodes that receive the messages and, optionally, output nodes that send out new or updated messages. Read the contents of the input message Modify message content with data from databases Modify database content with data from messages Construct new output messages created from all, part, or none of the input message in the Compute node only The following topics provide more information about these and other tasks that you can perform with ESQL.

Most of the examples included in the topics listed previously show parser-independent ESQL. Tutoial otherwise stated, these guidelines apply to messages in all message domains except the BLOB domain, for which you can implement a limited set of actions.

If required by the processing that tutoriap be performed on the message, ttutorial can include other nodes after the input node that complete the actions that your applications need. IBMintegrationMedia channel For community support, visit: For domain-specific information, use the appropriate link in the previous list.

You can run samples only eql you use the product documentation that is integrated with the IBM Integration Toolkit.

This message is provided in XML source format with tags and attributessee Example message. The topics specific to the MRM domain use the message that is created in the following sample: Where this occurs, the input message is included in the topic that refers to it.

You can use the Mapping node to customize the processing visually. Writing ESQL esqo ESQL provides a rich and flexible syntax for statements and functions that enable you to check and manipulate message and database content. Some of the built-in nodes enable you to customize the processing that they provide.

If examples include a reference to MRM, they assume that you have modeled the message in the MRM and that you have set the names of the MRM objects to be identical to the names of the corresponding tags or attributes in the XML source message. Designing a message flow. The ComputeDatabaseDatabaseInputand Filter nodes require you to provide a minimum level of ESQL, and you can provide much more than the minimum to control precisely the behavior of each node.

For more information, see Using message maps ESQL provides a rich and flexible syntax for statements and functions that enable you to exql and manipulate message and database content.

The example message is shown in the following diagram. The following topics provide additional information specific to the parser that you have specified for the input message:.

This set of topics discusses ESQL and the ways in which you can use it to essl these nodes. For more information, see Using message maps. A few other input messages are used to show ESQL that provides function tutoial messages with a structure or content that is not included in the Invoice or Video samples.
