A table OTD represents a database table. It consists of fields and methods. Fields correspond to the columns of a table while methods are the operations that you can apply to the OTD. This allows you to perform query, update, insert, and delete SQL operations in a table. The ability to update via a resultset is called “Updatable Resultset”, which is a feature supported by this adapter.
By default, the Table OTD has UpdatableConcurrency and ScrollTypeForwardOnly. Normally you do not have to change the default setting.
The type of result returned by the select() method can be specified using:
SetConcurrencytoUpdatable
SetConcurrencytoReadOnly
SetScrollTypetoForwardOnly
SetScrollTypetoScrollSensitive
SetScrollTypetoInsensitive
Execute the select() method with the “where” clause specified if necessary.
Loop through the ResultSet using the next() method.
Process the return record within a while() loop.
For example:
package prjVSAM_JCDjcdALL; public class jcdTableSelect { public com.stc.codegen.logger.Logger logger; public com.stc.codegen.alerter.Alerter alerter; public com.stc.codegen.util.CollaborationContext collabContext; public com.stc.codegen.util.TypeConverter typeConverter; public void receive( com.stc.connector.appconn.file. FileTextMessage input, otdVSAM.OtdVSAMOTD otdVSAM_1, dtd. otdOutputDTD_1935483687.Emp otdOutputDTD_Emp_1, com.stc.connector. appconn.file.FileApplication FileClient_1 ) throws Throwable { FileClient_1.setText( "Selecting record(s) from CICSEMP table via table select .." ); FileClient_1.write(); otdVSAM_1.getCICSEMP().select( input.getText() ); while (otdVSAM_1.getCICSEMP().next()) { otdOutputDTD_Emp_1.setENAME( otdVSAM_1.getCICSEMP().getENAME() ); otdOutputDTD_Emp_1.setPHONE( typeConverter.intToString( otdVSAM_1. getCICSEMP().getPHONE(), "#", false, "" ) ); otdOutputDTD_Emp_1.setMAILID( otdVSAM_1.getCICSEMP().getMAILID() ); otdOutputDTD_Emp_1.setSALARY( otdVSAM_1.getCICSEMP().getSALARY(). toString() ); otdOutputDTD_Emp_1.setJOBID( typeConverter.doubleToString( otdVSAM_1.getCICSEMP().getJOBID(), "#.000000;-#.000000", false, "" ) ); otdOutputDTD_Emp_1.setEMPID( typeConverter.intToString( otdVSAM_1.getCICSEMP().getEMPID(), "#", false, "" ) ); otdOutputDTD_Emp_1.setDEPTID( typeConverter.shortToString( otdVSAM_1.getCICSEMP().getDEPTID(), "#", false, "" ) ); otdOutputDTD_Emp_1.setDEPARTMENT( otdVSAM_1.getCICSEMP().getDEPARTMENT() ); FileClient_1.setText( otdOutputDTD_Emp_1.marshalToString() ); FileClient_1.write(); } FileClient_1.setText( "Done table select." ); FileClient_1.write(); } } |
Execute the insert() method. Assign a field.
Insert the row by calling insertRow()
This example inserts an employee record:
package prjVSAM_JCDjcdALL; public class jcdInsert { public com.stc.codegen.logger.Logger logger; public com.stc.codegen.alerter.Alerter alerter; public com.stc.codegen.util.CollaborationContext collabContext; public com.stc.codegen.util.TypeConverter typeConverter; public void receive( com.stc.connector.appconn.file.FileTextMessage input, dtd.otdInputDTD_622919076.Emp otdInputDTD_Emp_1, otdVSAM.OtdVSAMOTD otdVSAM_1, com.stc.connector.appconn.file.FileApplication FileClient_1 ) throws Throwable { FileClient_1.setText( "Inserting records into CICSEMP table .." ); FileClient_1.write(); otdInputDTD_Emp_1.unmarshalFromString( input.getText() ); otdVSAM_1.getCICSEMP().insert(); for (int i1 = 0; i1 < otdInputDTD_Emp_1.countX_sequence_A(); i1 += 1) { otdVSAM_1.getCICSEMP().setENAME( otdInputDTD_Emp_1.getX_sequence_A( i1 ).getENAME() ); otdVSAM_1.getCICSEMP().setPHONE( typeConverter.stringToInt( otdInputDTD_Emp_1.getX_sequence_A( i1 ).getPHONE(), "#", false, 0 ) ); otdVSAM_1.getCICSEMP().setMAILID( otdInputDTD_Emp_1.getX_sequence_A( i1 ).getMAILID() ); otdVSAM_1.getCICSEMP().setSALARY( new java.math.BigDecimal( otdInputDTD_Emp_1.getX_sequence_A( i1 ).getSALARY() ) ); otdVSAM_1.getCICSEMP().setJOBID( typeConverter.stringToDouble( otdInputDTD_Emp_1.getX_sequence_A( i1 ).getJOBID(), "#.000000;-#.000000", false, 0 ) ); otdVSAM_1.getCICSEMP().setEMPID( typeConverter.stringToInt( otdInputDTD_Emp_1.getX_sequence_A( i1 ).getEMPID(), "#", false, 0 ) ); otdVSAM_1.getCICSEMP().setDEPTID( typeConverter.stringToShort( otdInputDTD_Emp_1.getX_sequence_A( i1 ).getDEPTID(), "#", false, 0 ) ); otdVSAM_1.getCICSEMP().setDEPARTMENT( otdInputDTD_Emp_1.getX_sequence_A( i1 ).getDEPARTMENT() ); otdVSAM_1.getCICSEMP().insertRow(); } FileClient_1.setText( "Done Insert." ); FileClient_1.write(); } } |
Execute the update() method.
Using a while loop together with next(), move to the row that you want to update.
Assign updating value(s) to the fields of the table OTD
Update the row by calling updateRow().
package prjVSAM_JCDjcdALL; public class jcdUpdate { public com.stc.codegen.logger.Logger logger; public com.stc.codegen.alerter.Alerter alerter; public com.stc.codegen.util.CollaborationContext collabContext; public com.stc.codegen.util.TypeConverter typeConverter; public void receive( com.stc.connector.appconn.file.FileTextMessage input, otdVSAM.OtdVSAMOTD otdVSAM_1, dtd.otdOutputDTD_1935483687. Emp otdOutputDTD_Emp_1, com.stc.connector.appconn.file.FileApplication FileClient_1 ) throws Throwable { FileClient_1.setText( "Update the Department .. " ); FileClient_1.write(); otdVSAM_1.getCICSEMP().update( input.getText() ); while (otdVSAM_1.getCICSEMP().next()) { otdVSAM_1.getCICSEMP().setDEPARTMENT( "QAQAQA" ); otdVSAM_1.getCICSEMP().updateRow(); } FileClient_1.setText( "Done Update." ); FileClient_1.write(); } } |
Execute the delete() method.
In this example DELETE an employee.
package prjVSAM_JCDjcdALL; public class jcdDelete { public com.stc.codegen.logger.Logger logger; public com.stc.codegen.alerter.Alerter alerter; public com.stc.codegen.util.CollaborationContext collabContext; public com.stc.codegen.util.TypeConverter typeConverter; public void receive( com.stc.connector.appconn.file. FileTextMessage input, otdVSAM.OtdVSAMOTD otdVSAM_1, dtd. otdOutputDTD_1935483687.Emp otdOutputDTD_Emp_1, com.stc.connector. appconn.file.FileApplication FileClient_1 ) throws Throwable { FileClient_1.setText( "Delete record .." ); FileClient_1.write(); otdVSAM_1.getCICSEMP().delete( input.getText() ); FileClient_1.setText( "Done delete." ); FileClient_1.write(); } } |
