Method Detail

getRecordCheck

protected abstract String getRecordCheck(InsertOrUpdateStatement insertOrUpdateStatement,
                                         Database database,
                                         String whereClause)

getElse

protected abstract String getElse(Database database)

getPostUpdateStatements

protected String getPostUpdateStatements(Database database)

getPriority

public int getPriority()

Description copied from interface: SqlGenerator

Of all the SqlGenerators that "support" a given SqlStatement/Database, SqlGeneratorFactory will return the one with the highest priority.

Specified by:

getPriority in interface PrioritizedService

Specified by:

getPriority in interface SqlGenerator<InsertOrUpdateStatement>

Overrides:

getPriority in class AbstractSqlGenerator<InsertOrUpdateStatement>

validate

public ValidationErrors validate(InsertOrUpdateStatement statement,
                                 Database database,
                                 SqlGeneratorChain sqlGeneratorChain)

Description copied from interface: SqlGenerator

Validate the data contained in the SqlStatement. If there are no errors, return an empty ValidationErrors object, not a null value. Liquibase will inspect the ValidationErrors result before attempting to call generateSql.

getWhereClause

protected String getWhereClause(InsertOrUpdateStatement insertOrUpdateStatement,
                                Database database)

getInsertStatement

protected String getInsertStatement(InsertOrUpdateStatement insertOrUpdateStatement,
                                    Database database,
                                    SqlGeneratorChain sqlGeneratorChain)

getUpdateStatement

protected String getUpdateStatement(InsertOrUpdateStatement insertOrUpdateStatement,
                                    Database database,
                                    String whereClause,
                                    SqlGeneratorChain sqlGeneratorChain)
                             throws LiquibaseException

Parameters:

insertOrUpdateStatement -

database -

whereClause -

sqlGeneratorChain -

Returns:

the update statement, if there is nothing to update return null

Throws:

LiquibaseException

generateSql

public Sql[] generateSql(InsertOrUpdateStatement insertOrUpdateStatement,
                         Database database,
                         SqlGeneratorChain sqlGeneratorChain)

Description copied from interface: SqlGenerator

Generate the actual Sql for the given statement and database.
