public String getSchemaName()

getViewName

public String getViewName()

getSelectQuery

public String getSelectQuery()

getReplaceIfExists

public Boolean getReplaceIfExists()

setReplaceIfExists

public void setReplaceIfExists(Boolean replaceIfExists)

Specified by:

setReplaceIfExists in interface ReplaceIfExists

getFullDefinition

public Boolean getFullDefinition()

getPath

public String getPath()

getRelativeToChangelogFile

public Boolean getRelativeToChangelogFile()

getEncoding

public String getEncoding()

getRemarks

public String getRemarks()

validate

public ValidationErrors validate(Database database)

Description copied from class: AbstractChange

Implementation checks the ChangeParameterMetaData for declared required fields and also delegates logic to the SqlGenerator.validate(liquibase.statement.SqlStatement, liquibase.database.Database, liquibase.sqlgenerator.SqlGeneratorChain) method on the SqlStatement objects returned by Change.generateStatements(liquibase.database.Database). If no or null SqlStatements are returned by generateStatements then this method returns no errors. If there are no parameters than this method returns no errors

Specified by:

validate in interface Change

Overrides:

validate in class AbstractChange

generateStatementsVolatile

public boolean generateStatementsVolatile(Database database)

Description copied from class: AbstractChange

Implementation delegates logic to the SqlGenerator.generateStatementsIsVolatile(Database) method on the SqlStatement objects returned by Change.generateStatements(liquibase.database.Database). If zero or null SqlStatements are returned by generateStatements then this method returns false.

Specified by:

generateStatementsVolatile in interface Change

Overrides:

generateStatementsVolatile in class AbstractChange

openSqlStream

protected InputStream openSqlStream()
                             throws IOException

Throws:

IOException

getExcludedFieldFilters

public String[] getExcludedFieldFilters(ChecksumVersion version)

Overrides:

getExcludedFieldFilters in class AbstractChange

generateCheckSum

public CheckSum generateCheckSum()

Calculates the checksum based on the contained SQL.

Specified by:

generateCheckSum in interface Change

Overrides:

generateCheckSum in class AbstractChange

See Also:

• Change#generateCheckSum(ChecksumVersion)

generateStatements

public SqlStatement[] generateStatements(Database database)

Description copied from interface: Change

Generates the SqlStatement objects required to run the change for the given database.

NOTE: This method may be called multiple times throughout the changelog execution process and may be called in documentation generation and other integration points as well.

If this method reads from the current database state or uses any other logic that will be affected by whether previous changeSets have ran or not, you must return true from Change.generateStatementsVolatile(liquibase.database.Database).

Specified by:

generateStatements in interface Change

createViewStatement

protected CreateViewStatement createViewStatement(String catalogName,
 String schemaName,
 String viewName,
 String selectQuery,
 boolean replaceIfExists)

getConfirmationMessage

public String getConfirmationMessage()

Description copied from interface: Change

Confirmation message to be displayed after the change is executed. Should include relevant configuration settings to make it as helpful as possible. This method may be called outside the changelog execution process, such as in documentation generation.

Specified by:

getConfirmationMessage in interface Change

createInverses

protected Change[] createInverses()

Description copied from class: AbstractChange

Create inverse changes that can roll back this change. This method is intended to be overridden by Change implementations that have a logical inverse operation. Default implementation returns null.

If AbstractChange.generateRollbackStatements(liquibase.database.Database) is overridden, this method may not be called.

Overrides:

createInverses in class AbstractChange

Returns:

Return null if there is no corresponding inverse and therefore automatic rollback is not possible. Return an empty array to have a no-op rollback.

See Also:

• #supportsRollback

checkStatus

public ChangeStatus checkStatus(Database database)

Description copied from interface: Change

Validate that this change executed successfully against the given database. This will check that the update completed at a high level plus check details of the change. For example, a change to add a column will check that the column exists plus data type, default values, etc.

Specified by:

checkStatus in interface Change

Overrides:

checkStatus in class AbstractChange

getSerializedObjectNamespace

public String getSerializedObjectNamespace()

Specified by:

getSerializedObjectNamespace in interface LiquibaseSerializable

Overrides:

getSerializedObjectNamespace in class AbstractChange

customLoadLogic

protected void customLoadLogic(ParsedNode parsedNode,
 ResourceAccessor resourceAccessor)
                        throws ParsedNodeException

Overrides:

customLoadLogic in class AbstractChange

Throws:

ParsedNodeException
