General syntax for add parameter methods

The general syntax of these methods is as follows:

Syntax

public void addProgressType(int position, DataTypevalue, int mode,
                     [ int extentValue|MetaTypemetaData])
            throws Open4GLException

ProgressType

Indicates the ABL data type of the parameter, such as Decimal in addDecimal(), for adding a parameter of data type DECIMAL.

position

Specifies a 0-based index indicating the parameter position.

DataType

Specifies the Java data type of the parameter, for example, java.math.BigDecimal or java.math.BigDecimal[].

value

Specifies a variable that contains the value of the parameter, or null for an OUTPUT parameter.

mode

Specifies the ABL mode (passing direction) of the parameter. This can be one of the following constant values:

• ParamArrayMode.INPUT
• ParamArrayMode.INPUT_OUTPUT
• ParamArrayMode.OUTPUT

extentValue

Specifies the extent of an array for methods that add an array parameter (where ProgressType is appended with Array, as in AddDecimalArray()).

MetaType

Specifies one of the following classes for methods that add a temp-table or ProDataSet parameter:

• ProResultSetMetaDataImpl — Provides the schema information for temp-table parameters that are mapped to a java.sql.ResultSet. For more information on defining this schema, see Define the schema for a temp-table parameter mapped to a java.sql.ResultSet.
• ProDataGraphMetaData — Provides the schema information for ProDataSet parameters and temp-table parameters that are mapped to a com.progress.open4gl.ProDataGraph. For more information on defining the schema for ProDataSet parameters, see Define the schema for a ProDataSet parameter. For more information on defining the schema for temp-table parameters mapped to a ProDataGraph, see Define the schema for a temp-table parameter mapped to a ProDataGraph.

metaData

Specifies an instance of MetaType. When mode is ParamArrayMode.OUTPUT and ProgressType is DatasetHandle or TableHandle (passing a dynamic ProDataSet or temp-table parameter), you can set this parameter to null.
