addData

void sqlDataManager.addData ( String table, Map data ) (professional and enterprise editions only)
void sqlDataManager.addData ( String table, String columnName, Object value ) (professional and enterprise editions only)

Description

Add data to fields, in preparation for insertion into a database.

When adding data in a many-to-many relation, if setAutoManyToMany is set to false, a null row should be inserted into the relating table so the datamanager will link the keys correctly between related tables. For example, dm.addData("many_to_many", null);

Before adding data the first time, you must build the schema of any tables you will use, as well as add foreign keys if you are not using a database engine that natively supports them (such as InnoDB for MySQL).

Parameters

table Name of the database table that the data corresponds to, as a string.
data (this or columnName and value) Map using field names as keys to desired values to be added in the database for fields. This can be a dataRecord object.
columnName (requires value) The name of the column/field in the database table that the data is being added for, as a string.
value (requires columnName) The value being inserted into the column/field.

The SqlDataManager will attempt to convert a value that is given to the correct format for the database. For example, if the database requires an int for a column named age, dm.addData("table", "age", "32") will convert the String "32" to an int before adding it to the database. See the table below the examples for other types of java objects and how they map to SQL types.

The table and columnName parameters are not case sensitive. The same is true for the key values in the data map.

Return Values

Returns void.

Examples

Add Data from Data Record

// Get datamanager
dm = session.getv( "DATAMANAGER" );

// Add DataRecord Information into person table
dm.addData( "person", dataRecord );

// Create and add query to buffer
dm.commit( "person" );

Add Data In a Specific Field

// Get datamanager
dm = session.getv( "DATAMANAGER" );

// Add DataRecord Information into person table
dm.addData( "person", dataRecord );

// Add Specific Other Data
dm.addData( "person", "date_collected", "2010-07-13" );

// Create and add query to buffer
dm.commit( "person" );

Java Object and SQL Type Mappings

Since the DataManager is designed with screen-scraper in mind all inputs support using the String type in addition to their corresponding Java object type, but the String needs to be parseable into the corresponding data type. For example if there is a column that is defined as an Integer in the database then the String needs to be parseable by Integer.parseInt(String value). Here is a mapping of the sql types (based on java.sql.Types) to Java objects:

SQL Type		Java Object
java.sql.Types.CHAR		String
java.sql.Types.VARCHAR		String
java.sql.Types.LONGVARCHAR		String
java.sql.Types.LONGNVARCHAR		String
java.sql.Types.NUMERIC		BigDecimal
java.sql.Types.DECIMAL		BigDecimal
java.sql.Types.TINYINT		Integer
java.sql.Types.SMALLINT		Integer
java.sql.Types.INTEGER		Integer
java.sql.Types.BIGINT		Long
java.sql.Types.REAL		Float
java.sql.Types.FLOAT		Double
java.sql.Types.DOUBLE		Double
java.sql.Types.BIT		Boolean
java.sql.Types.BINARY		ByteArray
java.sql.Types.VARBINARY		ByteArray
java.sql.Types.LONGVARBINARY		ByteArray
java.sql.Types.DATE		SQLDate or Long
java.sql.Types.TIME		SQLTime or Long
java.sql.Types.TIMESTAMP		SQLTime or Long
java.sql.Types.ARRAY		Object
java.sql.Types.BLOB		ByteArray
java.sql.Types.CLOB		Object
java.sql.Types.JAVA_OBJECT		Object
java.sql.Types.OTHER		Object
