Migration Commands

Command Syntax

This syntax developed by considering four types of profiles. Please find the details in Profiles. Where default profiles are blank. Need not to mention in Maven build. 

# mvn clean install -P[[[diff]database,]context,]command
# mvn clean install -P[[[dat,]mys,]dev,]log

mvn clean install -Pmys,dev,log      # mysql , development
mvn clean install -Pora,pro,log      # oracle, production
mvn clean install -Pdev,log          # h2    , development
mvn clean install -Plog              # h2    , development

Generate Change Log

# exclude data
mvn clean install -Pmys,dev,log      # mysql , development
mvn clean install -Pora,pro,log      # oracle, production
mvn clean install -Pdev,log          # h2    , development
mvn clean install -Plog              # h2    , development

# include data
mvn clean install -Pdat,mys,dev,log   # mysql , development
mvn clean install -Pdat,ora,pro,log   # oracle, production
mvn clean install -Pdat,dev,log       # h2    , development
mvn clean install -Pdat,log           # h2    , development

Differential Change Log

# exclude data
mvn clean install -Pmys,dev,dif      # mysql , development
mvn clean install -Pora,pro,dif      # oracle, production
mvn clean install -Pdev,dif          # h2    , development
mvn clean install -Pdif              # h2    , development

# include data
mvn clean install -Pdat,mys,dev,dif   # mysql , development
mvn clean install -Pdat,ora,pro,dif   # oracle, production
mvn clean install -Pdat,dev,dif       # h2    , development
mvn clean install -Pdat,dif           # h2    , development

Synchronize Change Log

mvn clean install -Pmys,dev,syn                        # mysql , development
mvn clean install -Pora,pro,syn                        # oracle, production
mvn clean install -Pdev,syn                            # h2    , development
mvn clean install -Psyn                                # h2    , development

Migrate/Update Database

mvn clean install -Pmys,dev,upd                        # mysql , development
mvn clean install -Pora,pro,upd                        # oracle, production
mvn clean install -Pdev,upd                            # h2    , development
mvn clean install -Pupd                                # h2    , development

Rollback Change Log

mvn clean install -Pmys,dev,rol -Dchorke.tag=20131216  # mysql , development
mvn clean install -Pora,pro,rol -Dchorke.tag=20131216  # oracle, production
mvn clean install -Pdev,rol -Dchorke.tag=20131216      # h2    , development
mvn clean install -Prol -Dchorke.tag=20131216          # h2    , development

Drop All/Clean Database

mvn clean install -Pmys,dev,del                        # mysql , development
mvn clean install -Pora,pro,del                        # oracle, production
mvn clean install -Pdev,del                            # h2    , development
mvn clean install -Pdel                                # h2    , development

Profiles

Four types of profiles are considerate for Maven build. Please find those profiles details are as respectively as below:

  1. Diff (dat, default)
  2. Database (der, h2d, hsq, mys, ora, pos, default)
  3. Context (dev, dmo, qac, uat, pro, default)
  4. Command (Change Log(log), Different(dif), Synchronise(syn), Update(upd), Clear Checksum(cle), Rollback(rol), Empty DB(del))
  5. labels (ddl,dml)
    1. DDL:
      1. Operations: ddl, create(new), alter(alt), drop(dro)
      2. Constraints: Foreign(fkc), Not Null(nnc), Primary(pkc), Unique(ukc)
      3. Objects: table(tbl), sequence(sqn), column(col), index(idx), view(vue), function(fun), procedure(pro)
    2. DML: dml, csv, insert(ins), update(upd), delete(del)

Where default profiles are blank. Need not to mention in Maven build.
