  integercbdsnmax,refintegerpcbdsn,refstringszdescription,integercbdescriptionmax,refintegerpcbdescription)library"odbc32.dll"
  functionintegerSQLAllocConnect(longhenv,reflonghdbc)library"odbc32.dll"
  functionintegerSQLConnect(longhstmt,refstringszdsn,integerdsnlen,refstring
  szuid,integeruidlen,refstringszpwd,integerpwdlen)library"odbc32.dll"
  functionintegerSQLDisconnect(longhdbc)library"odbc32.dll"
  functionintegerSQLAllocStmt(longhdbc,reflonghstmt)library"odbc32.dll"
