Running a SELECT query over an IBMDB2I table with a cp1250 character set was producing an error 2027 (ibmdb2i error 2027: Error converting single-byte sort sequence to UCS-2). The QMY_DESCRIBE_RANGE API was returning error 2027 to the storage engine because the CCSID used for a cp1250 column (870) does not match the CCSID used by the DB2 sort sequences associated with cp1250_* collations (1153). This was because the storage engine relies on a set of system APIs to determine which CCSID value most closely matches a particular MySQL character set. However, in the case of cp1250, the system is returning CCSID 870, which does not have a codepoint for the euro symbol, making it an incorrect match. This patch overrides the selection of a compatible CCSID to always return 1153 for cp1250. storage/ibmdb2i/db2i_charsetSupport.cc: Bug#45197 cp1250 character set with IBMDB2I generates 2027 error override the selection of a compatible CCSID to always return 1153 for cp1250.
