SQLScript Editor

SQLScript Debugger

SQLScript Language

User Defined Functions

SQLScript Editor


SQLScript Editor

Procedure wizardNew artifact hierarchyRenamed to “Stored Procedure”


SQLScript Editor

Two file formats.hdbprocedure is the new artifact type which will be the recommended file format moving forward..procedure is still supported, but has been deprecated and eventually will be removed.Procedure templates are still supported but currently only via .procedure format.


SQLScript Editor

Source Code Editor for .hdbprocedureCREATE keyword is now removedExplicit schema definitionPackage/procedure name separator is now double colon(::)No local table types definition. Use CDS(.hdbdd) to define global table types


SQLScript Editor

SQLScript ViewerProcedures in the catalog can now be viewed in the SQLScript editor in read-only mode.Allows for setting/removing of breakpoints within the runtime object.

SQLScript Debugger


SQLScript Debugger

Debug catalog proceduresDebug configuration now allows for debugging of both design time(repository) and run-time(catalog) proceduresOpen the run-time procedure from the catalog and set breakpointsWithin the debug configuration, choose


SQLScript Debugger

New Debugging Authorization ConceptPrior to SPS 07, users were allowed to debug everything by simply having authorization to SYS.DEBUG, this authorization is no longer required in SPS 07Restricts 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 ConceptProcedures 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

}
