DSQL map features
Talend Data Mapper provides a few features in DSQL maps on top of the existing Data Shaping Language functions.
You can find the documentation for the other Data Shaping Language functions in the Talend Data Shaping Language Reference Guide.
getContextVariable
You can use the getContextVariable function to call a context variable defined in your Talend Studio Job.
Arguments
Name of the context variable.
getMapProperty
You can use the getMapProperty function to retrieve the value of an execution property. This function is particularly useful in Camel Routes (including the cMap component) to access exchange inbound headers.
Arguments
Name of the execution property as a string literal.
Examples
getMapProperty('propertyName')If the specified property does not exist, the function returns null.
java:call
You can use the java:call feature to call a Java method. This can be used to call beans and routines available in Talend Studio for example.

Java parameters.
- Call to a static method: java:call(<class_name>, <method_name>, <arguments>)
- Call to a non-static method: java:call(java:new(<class_name>, <constructor_arguments>), <method_name>, <arguments>)
- Call to a non-static method of a Java object returned by another method of a Java object: java:call(java:call(<class_name>, <method_name>, <arguments>), <method_name>, <arguments>)
