Cursor Concurrency (ODBC)

  • Статья

Cursor operations, like cursor types, are affected by the concurrency options set by the application. Concurrency options are set using the SQL_ATTR_CONCURRENCY option of SQLSetStmtAttr. The concurrency types are:

  • Read-only (SQL_CONCUR_READONLY)
  • Values (SQL_CONCUR_VALUES)
  • Row version (SQL_CONCUR_ROWVER)
  • Lock (SQL_CONCUR_LOCK)

For more information about the types of locks generated by these concurrency options, see Параллелизм курсоров (компонент Database Engine).
