JDBC Flags
Applies to ✅ Open Source Edition ✅ Express Edition ✅ Professional Edition ✅ Enterprise Edition
JDBC statements feature a couple of flags that influence the execution of such a statement. Each of these flags can be configured through jOOQ's org.jooq.Query and org.jooq.ResultQuery on a statement-per-statement basis, but there's also the possibility to centrally specify a value for these flags. These are the three flags:
-
queryTimeout: The JDBC statement timeout in seconds. Corresponds to Query.queryTimeout() or Statement.setQueryTimeout() -
maxRows: The maximum number of rows returned by the JDBC statement. Corresponds to ResultQuery.maxRows() or Statement.setMaxRows() -
fetchSize: The number of rows to be buffered by the JDBC ResultSet. Corresponds to ResultQuery.fetchSize() or Statement.setFetchSize()
All of these flags are JDBC-only features with no direct effect on jOOQ. jOOQ only passes them through to the underlying statement.
Programmatic configuration
Settings settings = new Settings()
.withQueryTimeout(5)
.withMaxRows(1000)
.withFetchSize(20);
XML configuration
<settings xmlns="http://www.jooq.org/xsd/jooq-runtime-3.9.0.xsd"> <queryTimeout>5</queryTimeout> <maxRows>1000</maxRows> <fetchSize>20</fetchSize> </settings>
