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 Cursor Concurrency (Database Engine).
