Cursor Concurrency (ODBC)

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 Simultaneidad de cursor (motor de base de datos).
