A_MSSQL_NO_TABLE_LOCKS

Setting this variable to On means the interface does not use the AcuOpenTables1 table, which causes all table locking to be disabled. This can improve performance on OPEN and CLOSE statements. While the default value is Off (false, no), this variable can also take the value of On (true, yes).

For information about AcuOpenTables1, see Table Locking.
