The GenericSQLInsertReceiver is used to insert a Domain's generated data directly into a database table via a JDBC connection.
The GenericSQLInsertReceiver requires that the following parameters are defined:
- resourceName - Defines the name of the resource that contains the database connection information on a user's local machine.
- databaseName - Defines the name of the database to access.
- tableName - Defines the name of the database table to insert rows into.
- uniqueAttribute - Defines a Domain Attribute the Receiver will use to identify a unique value that has already been inserted into the table to prevent duplicate data entry where a unique constraint is required.
- truncate - Truncates the table before inserting rows by executing a 'delete from table' statement.
- statementSeparator - Defines when a SQL statement has ended.
Column Data Types
This Receiver uses a set of standard data types to populate columns within most database tables; these column data types should successfully work with most databases that allow for data insertion via JDBC. The column data types are the following:
- String - gets translated to a VARCHAR
- Boolean - native data type
- BigDecimal - gets translated to a DECIMAL
- Date - native data type
- Double - native data type
- Float - native data type
- Integer - native data type
- Long - gets translated to a BIGINT
- Time - native data type
- Timestamp - native data type
JDBC Configuration File
This Receiver uses a configuration file, located on the user's local computer, as a resource to attain the necessary information for connecting to a user's local database via JDBC. The required properties to connect to a database via JDBC are the following:
- driver - the path and file name of the JDBC library for the database to connect to.
- user - the name used to connect as a user to the database.
- password - the password used to connect as the given user to the database.
- url - the JDBC universal resource locator required to connect to the given database.
- batchCount - defines the number of rows of generated data that are batched together before writing to the database.
Example JDBC Configuration File
Below is an example of a JDBC configuration file defined to connect to a MySQL database called, acme:
driver=com.mysql.jdbc.Driver user=root password=openSaysMe url=jdbc:mysql://localhost:3306/acme?rewriteBatchedStatements=true batchCount=1000
Receiver Attribute Property Keys
The Receiver defines three property keys that can be modified on any of its associated Domain Attributes:
- columnName - Defines the name of the column as it is in the actual database table.
- columnType - Defines the column data type.
- include - Defines if the column should be included or excluded from the insert statement.
Example Setting of Receiver Property Key Values
