Automatically connect or not. If the value is true, use db.query() function or a SQL statement starting with $ directly to access the database; if it is false, there will be no automatic connection; you should first establish the connection with connect(db) statement before you can access the database.


<property name="autoConnect" value="true"/>

<!—Set whether to use schema name. For instance, when “UseSchema” value is set as true, the syntax in the automatically generated SQL statement is select tbl.col1,tbl.col2 from tb1; otherwise the syntax is select col1,col2 from tbl -->

<property name="useSchema" value="false"/>

<!-- Set whether to enclose object in quotes -->

<property name="addTilde" value="false"/>

<!-- Set whether to transcode the content retrieved from the database; when setting the value as true, the retrieved data will be transcoded for display when the database encoding is different from encoding at the frontend-->

<property name="needTransContent" value="false" />

<!-- Set whether to transcode the SQL statement because you may need to convert the type of encoded characters at the frontend into the database encoding type for SQL execution from frontend to the database -->

<property name="needTransSentence" value="false" />

<!-- Set whether to set case-sensitive for the SQL statement-->

<!-- esProc charset-->



Configure the search path of the script file. Multiple paths separated by ";" are allowed. The script file can also be placed in the application project’s classpath, which has the priority over the search path for file loading.



< splPath>D:\files\spl;D:\files\txt;D:\files</splPath>


<!—Date type, time type and other data types -->

<dateFormat> yyyy-MM-dd</dateFormat>


<dateTimeFormat> yyyy-MM-dd HH:mm:ss</dateTimeFormat>

<!-- Method one for data source configuration: configure connection pool and specify the data source name in the application server -->

<!-- esProc main path, which is a single absolute path -->

<mainPath> D:\files</mainPath>

<!-- The save path for temporary files; it can be an absolute path. If using a relative path, put it under the main path; don’t start a relative path with “/” or “\” -->


<!-- Set file buffer size, whose unit is byte -->


<!-- Set the maximum number of parallel tasks -->




<!-- Set the composite file block size -->


<!-- Set default number of subcursors in a multicursor -->


<!-- A null string in text data -->


<!-- Set the number of records fetched from the cursor -->


<!-- Configure external library directory-->




<!-- Log level, which can be OFF,SEVERE,WARNING,INFO,DEBUG; their priorities decrease in the order. Do not output any log information when log level is OFF; output WARNING, INFO, SERVERE when log level is INFO; and so on-->





<!—Default connection; the connected source can be one in DBList or in the following JNDIList -->


<!—Set JNDI data source –>


<JNDI name="jdbc/test">

//Database type number; 0-14 represents database types in order: [UNKNOWN:0; ORACLE:1; SQLSVR:2; SYBASE:3; SQLANY:4; INFMIX:5; FOXPRO:6; ACCESS:7; FOXBAS:8; DB2:9; MYSQL:10; KINGBASE:11; DERBY:12; HSQL:13; TERADATA:14;]

<property name="batchSize" value="1000"/>

// Reference database’s JNDI data source, the format is: java:comp/env/DataSource name.

<property name="lookup" value="java:comp/env/jdbc/test"/>



</JNDIList >

<!—The log record configuration properties file. See raqsoftLog.properties for details -->


<property name="logConfig" value="raqsoftLog.properties"/>



<!—Whether to read the runtime configurations or Server’s JNDIList; delete the unwanted one -->


<!—After the jdbc gateway is configured, all statements will be parsed by the script file and return a table sequence or a cursor; the script file has two parameters: sql and args (which is the sequence of sql’s parameters) -->


<!—Remote server list for a JDBC invoke for configuring IPs and port numbers of nodes -->






<!— The specified script file executed first for system initialization -->


</Init >


Both esProc JDBC and the Integrated Development Environment (IDE) share the same raqsoftConfig.xml file, so you can configure the above information on the IDE interface.

Click Tool>Options on the menu bar to edit the configuration information on the Option window. The key information related to JDBC, like paths, format of date and time and so on, can be edited on the Environment page:

General page also provides JDBC-related settings, such as log level and number of parallel tasks:

Besides, the raqsoftConfig.xml file’s data source information can be configured in the data source manager. Click Tool>Datasource connection on the menu bar to open the data source manager window:

You can add, delete or modify the data source configuration information in the data source manager. Click Edit to edit the connection parameters of the data source:

In the data source manager, you can set the data source driver, data source URL, user name, password, batch size, and other information. Note that demo is the system data source, whose connection parameters cannot be changed. In addition, esProc JDBC itself cannot be used as a data source during the data source connection configuration.

The <Server/> node configures connection pool, log configuration file, and other information. If a data source needs to be connected for the script file invoked through the esProc JDBC, the related information should be configured in raqsoftConfig.xml’s data source or connection pool. Particularly, if db.query() function or $(db) sql statement is used to directly access the database, the autoConnect property of this database should be true. For detailed information about esProc JDBC, refer to Java Invocation.

In the log configuration properties file raqsoftLog.properties , you can configure log levels and other information:

// Log levels include OFF, ERROR, WARN, INFO, DEBUG and ALL, whose priority levels decrease from left to right. Level OFF turns off logging.

// Log messages. Level INFO indicates that messages of levels ERROR, WARN and INFO will be exported; each level exports messages likewise.

// Specify name and log level for Logger.

// Format: Level (can be omitted; default level is INFO), log name 1, log name 2.



// Output log messages to the console. There are only two forms of message logging: console and file.


// INFO Log message level; messages whose priority levels are lower than it will be ignored. If it is omitted, level INFO is used by default.



// Output logs to the specified file.

// Specify the full path of LOG2; default full path is the application’s current working path.



// Default mode of logging is appending if not specified.



// Maximum number of bytes in a log file; the default value is infinite if not specified.



// Maximum number of backup files; the default value is 1 if not specified.




// Whether or not make the log name fixed; without making it fixed, a separate log file will be generated for each date according to the specified log file name


The raqsoftConfig.xml file in Java application’s classpath will be automatically loaded in the use of esProc JDBC, and cannot be renamed at this point. But if esProc JDBC’s connecting string uses the format like ...?config=..., the .xml file specified by config in the connecting string will be loaded for use in the configuration and the default file defined in the configuration will be ignored.

For example, with a connecting string like con= DriverManager.getConnection("jdbc:esproc:local:/?config=myconfig.xml"), the configuration in myconfig.xml will be used.
