HCK-14785: RE relationships

[chulanovskyi-bs]

HCK-14785 [DB2][RE from instance] relationships aren't REed from instance if schema name length is less than 8

Content:

• normalized schema names in DDL statements on RE.

Technical details

• The PR fixes the behavior of CALL SYSPROC.DB2LK_GENERATE_DDL, where the schema names are right padded by default. For examples:
  • schema name in the model is x
  • after applying it to the instance, trying to reverse it back as DDL will return:

-- "x"."t" definition

CREATE TABLE "x       "."t"  (
		  "c1" VARCHAR(20 OCTETS) )   
		 IN "IBMDB2SAMPLEREL"  
		 ORGANIZE BY ROW;

• This happens because the schema name was created as a fixed-length CHAR value (default 8) and is blank-padded internally to full length.
• This impacts the internal resolution of references on most levels (relationships, types, columns, views, etc.)
