Update Transactions - Code Examples

• Run the INSERT command using the Fabric user code as follows:

Db ci = db("fabric");

// Get the instance ID 
ci.execute("get Customer.'" + IID + "'");

// Begin Trx
ci.beginTransaction();

//Perform the INSERT command
String SQL = "INSERT into CONTRACT_COPY (CUSTOMER_ID,CONTRACT_ID,CONTRACT_REF_ID) values (?, ?, ?)";
Object[] params = new Object[]{IID, contrID, contrRefID};
ci.execute(SQL, params);

//Commit Trx
ci.execute("commit");

• Run the GET and INSERT commands from the Web Service within the same transaction as follows:

String getCommand = "get " + LU_NAME + ".'" + UID + "'";
Db ci = db("fabric");
String status = "SUCCESS";

try {
    ci.execute(getCommand);             
    String sql = "SELECT COUNT(*) NO_OF_ACT FROM ACTIVITY";    
    ludb(LU_NAME, UID).fetch(sql).each(row->{
    ci.beginTransaction();
    Object [] params = new Object[]{UID, 99, 0, "NA", row.cell(0) + " total num of activities for the customer"};
    //log.info("*-*-* Insert records into ACT_CASE_NOTE" );
    ci.execute("INSERT INTO ACT_CASE_NOTE (CUSTOMER_ID, ACTIVITY_ID, CASE_ID, CASE_NOTE_ID, CASE_NOTE_TEXT) VALUES (?, ?, ?, ?, ?)", params);
    ci.commit();
    });        
} catch (Exception e) {
    log.info("Insert failed: " + e.getMessage());
    ci.rollback();
    status = "FAILURE";    
}

• Run the transaction using the Fabric Console as follows:

 // get the instance ID  
 get Customer.22;

 // Begin Trx
 begin;

 // Run the UPDATE command
 update CONTRACT_COPY set CONTRACT_REF_ID = 'AXD1234' where CUSTOMER_ID = 22;    

 // Commit Trx
 commit;

• Run the Reference update transaction:

Db ci = db(“fabric”);
ci.beginTransaction(); 
ci.execute("INSERT INTO REF_STATUS (STATUS_CODE, STATUS_DESC) VALUES (?,?)", i_cd, i_desc);
ci.commit();
