DB2 - Problem description

Problem IC63665 Status: Closed

Query compilation fails with -901 "sqlnp_initlex [300]"

product:
DB2 FOR LUW / DB2FORLUW / 910 - DB2
Problem description:
Compiling a query that uses optimization guidelines may fail 
with SQLCODE -901 reason 
"sqlnp_initlex [300]". This happens when the guideline 
contains a malformed table reference.  In the following example, 
a double quote is missing from the table reference: 
 
SELECT C1 FROM "schema" . "table" 
     /*<OPTGUIDELINES><TBSCAN TABLE=' "schema . "table" 
 '/></OPTGUIDELINES>*/; 
 SQL0901N  The SQL statement failed because of a non-severe 
system error. 
Subsequent SQL statements can be processed. (Reason 
"sqlnp_initlex 
[300]:rc(     0)   ".) SQLSTATE=58004
