SQLScript Debugger
New Debugging Authorization Concept
Prior to SPS 07, users were allowed to debug everything by simply having authorization to
SYS.DEBUG, this authorization is no longer required in SPS 07
Restricts the ability to debug procedures which are owned by other users. You can grant debug
access for a procedure or for an entire schema to a specific user.


With the following authorizations, users can set breakpoints, show procedure source in debugger UI, and inspect
intermediate results.
Grant debug on <proc> to <user>
Grant debug on schema <schema> to <user>
 Without these authorizations, the procedures are handled like a black box.

Restricts the ability to attach debugger to running session. You can grant debug access for
attaching to running session to a specific user.


With the following authorizations, users can freeze execution of another user, and see data from another user.
Grant attach debugger to <user>

SQLScript Debugger
New Debugging Authorization Concept
Procedures created directly in the catalog are owned by the user which created them, so no additional
authorization is required to debug them.
Procedures created/activated via the repository(Development Perspective) are owned by
_SYS_REPO, therefore the user must grant debug authorization to himself. Users can not execute the
“grant” statements directly. The following procedures could be used if the user has authorization to these
procedures.



Call _SYS_REPO.GRANT_PRIVILEGE_ON_ACTIVATED_CONTENT('debug','<objectname>','<username>');
Call _SYS_REPO.GRANT_SCHEMA_PRIVILEGE_ON_ACTIVATED_CONTENT('debug','<schemaname>','<username>');

Usually, users will not have authorization to these procedures, so it is recommended to add these
authorizations via a role(.hdbrole) as shown below.
role I816013.testing.roles::debug {
schema I816013.testing.data:I816013_TEST.hdbschema: DEBUG, EXECUTE;
// grant debug to schema
sql object I816013.testing.procedures:get_product_sale_price.hdbprocedure: DEBUG, EXECUTE; // grant debug to procedure
}
