• Functionality Added or Changed

• Bugs Fixed

Functionality Added or Changed

• Built against the MySQL server 5.5.27 client library.

• Support of INOUT and OUT parameters. (WL #6116)

• Driver prepares statements on server.

Bugs Fixed

• Close proximity issue when handling OS signals in myodbc. (Bug #14303803)

• Several catalog or info functions could raise an incorrect error String data, right truncated when only partial information was requested. For example, if the application called SQLDescribeCol(hstmt, ColNumber, ColName, BufferLen, ....), but did not want the column name (ColName == NULL and BufferLen == 0). SQL_SUCCESS_WITH_INFO could also be returned rather than the correct value SQL_SUCCESS. This issue affected many ADO, DAO, and other applications.

  Affected functions include:

  Spurious error and incorrect return code:
  
  SQLDescribeCol
  SQLDescribeColA
  SQLDescribeColW
  SQLGetInfoA
  SQLGetInfoW
  
  Incorrect return code:
  
  SQLColAttribute
  SQLColAttributeW
  SQLGetConnectAttr
  SQLGetConnectAttrW
  SQLGetCursorName
  SQLGetCursorNameW
  SQLGetInfo
  SQLGetInfoW
  SQLNativeSql
  SQLNativeSqlW

  (Bug #14285620)

• Long table names crash OBDC driver. (Bug #14085211, Bug #65200)
