All Implemented Interfaces:

Serializable, javax.resource.cci.InteractionSpec

public class DLIInteractionSpec
extends com.ibm.ims.db.cci.InteractionSpecImpl

Use this class to access data from an IMS database with the IMS Universal Database Resource Adapter using DL/I-like queries. The DLInteractionSpec is used by an Interaction to execute the specified function on an IMS database.

Method Detail

setSSAList

public void setSSAList(String ssaList)

Sets the segment search argument list to be used with the DL/I query when the interaction is executed.

The following code example shows how to set the SSA qualification statement string to return the last patient admitted to all wards with more than five doctors and less than three nurses in hospital "ALEXANDRIA". The command *L means "last occurance".

 String query = "Hospital(HospName=ALEXANDRIA) Ward(Doccount>5 | Nurcount<3) Patient *L";
 iSpec.setSSAList(query);
 

Parameters:

ssaList - a String set with the SSA qualification statement

setPCBName

public void setPCBName(String pcbName)

Sets the name of the PCB the interaction will use when executed.

Parameters:

pcbName - the PCB name

getSSAList

public String getSSAList()

Returns the segment search argument list the interaction will use when executed.

Returns:

the segment search argument list represented in a String format.

getPCBName

public String getPCBName()

Returns the PCB name the interaction will use when executed.

Returns:

the PCB name

getFunctionName

public String getFunctionName()

Retrieves the function to be performed in this interaction by name.

Returns:

the function name ("CREATE", "RETREIVE", "UPDATE", or "DELETE") as a String value

setFunctionName

public void setFunctionName(String functionName)
                     throws javax.resource.ResourceException

Sets the function to be performed in this interaction by function name.

Parameters:

functionName - Valid values are "CREATE", "RETREIVE", "UPDATE", or "DELETE".

Throws:

javax.resource.ResourceException

getFunctionType

public int getFunctionType()

Retrieves the function to be performed in this interaction by type.

Returns:

the int constant value for the function (FUNC_CREATE, FUNC_RETRIEVE, FUNC_UPDATE, or FUNC_DELETE)

setFetchSize

public void setFetchSize(int rows)

Gives the DLI driver a hint as to the number of rows that should be fetched from the database when more rows are needed. The number of rows specified affects only result sets created using this interaction. If the value specified is zero, then the hint is ignored. The default value is zero.

Overrides:

setFetchSize in class com.ibm.ims.db.cci.InteractionSpecImpl

Parameters:

rows - the number of rows to fetch

getFetchSize

public int getFetchSize()

Retrieves the number of result set rows that is the default fetch size for DLIResultSet objects generated from this interaction.

Overrides:

getFetchSize in class com.ibm.ims.db.cci.InteractionSpecImpl

Returns:

the default fetch size for result sets generated from this interaction.
