* In XQuery, local options can be set via option declarations and pragmas (see [[XQuery Extensions#Pragmas|pragmas]]).
If options are changed by operations in the [[GUI]], the underlying commands will be listed in the [[GUI#Visualizations|Info View]].<br/><br/>

===FAIRLOCK===
{| width='100%'
| '''Summary'''
|Defines the locking strategy:
* By default, non-fair is used. Read transactions will be favored, and transactions that access no databases can be evaluated even if the limit of parallel transactions (specified via {{Option|PARALLEL}} ) has been reached. This prevents update operations from blocking all other requests (for . For example, the DBA can further be used to see which jobs are running, even if the queue is full).
* If fair locking is enabled, read and write transactions will be treated equally (first in, first out). This avoids starvation of update operations, and it should be used if the prompt evaluation of update operations is critical.

| '''Summary'''
|This is a list of hosts that should be directly accessed. If the value is an empty string, it will be ignored.

===IGNOREHOSTNAME===
{{Mark|Introduced with Version 9.0.}}

|{{Code|IGNOREHOSTNAME [boolean]}}
|-
| '''Default'''
|{{Code|false}}
|-
| '''Summary'''
|If this option is enabled, hostnames of certificates will not be verified. Use {{Option|IGNORECERT}} to completely disable certificate verification.
|}
|-
| '''Summary'''
|This option can be turned on to ignore untrusted certificates when connecting to servers. Please use this option carefullyUse {{Option|IGNOREHOSTNAME}} to suppress only the hostname verification.

| '''Summary'''
===PARSERESTXQ===
{| width='100%'
|-
| '''Summary'''
|By default, if BaseX is run as [[Web Application]], a database server instance will be started as soon as the first HTTP service is calledwell. The server can then be addressed by other BaseX clients in parallel to the HTTP services.<br/>If the option is set to {{Code|falsetrue}}, the database server will be disabled.

===ENFORCEINDEX===
{{Mark|Introduced with Version 9.0:}}:
{| width='100%'
| '''Summary'''
|Enforces index rewritings in path expressions (see [[Indexes#Enforce Rewritings|Enforce Rewritings]] for details).
|}
===COPYNODE===
{{Mark|Introduced with Version 9.0:}}
{| width='100%'
|-
| width='120' | '''Signature'''
|{{Code|COPYNODE [boolean]}}
|-
| '''Default'''
|{{Code|true}}
|-
| '''Summary'''
|When creating new nodes in XQuery via [https://www.w3.org/TR/xquery-31/#id-constructors Node Constructors], all enclosed nodes will be copied, and all resulting nodes will get new node identities. This step can be very expensive, and it can be disabled with this option. The option should be used carefully, as it changes the standard behavior of XQuery. It should preferrably be used in [[XQuery Extensions#Database Pragmas|Pragmas]].
