Constructor Details

PostgreSqlDdlBuilder

public PostgreSqlDdlBuilder()

Method Details

mapDefaultValue

public String mapDefaultValue(Object defaultValue,
 Column column)

Specified by:

mapDefaultValue in interface IDdlBuilder

Overrides:

mapDefaultValue in class AbstractDdlBuilder

isUsePseudoSequence

public static boolean isUsePseudoSequence()

isMapCharToJson

public static boolean isMapCharToJson()

dropTable

protected void dropTable(Table table,
 StringBuilder ddl,
 boolean temporary,
 boolean recreate)

Description copied from class: AbstractDdlBuilder

Outputs the DDL to drop the table. Note that this method does not drop foreign keys to this table. Use #dropTable(Database, Table) if you want that.

Overrides:

dropTable in class AbstractDdlBuilder

recreate - TODO

writeAlterColumnDataTypeToBigInt

protected boolean writeAlterColumnDataTypeToBigInt(ColumnDataTypeChange change,
 StringBuilder ddl)

Overrides:

writeAlterColumnDataTypeToBigInt in class AbstractDdlBuilder

writeExternalIndexDropStmt

public void writeExternalIndexDropStmt(Table table,
 IIndex index,
 StringBuilder ddl)

Description copied from class: AbstractDdlBuilder

Generates the statement to drop a non-embedded index from the database.

Overrides:

writeExternalIndexDropStmt in class AbstractDdlBuilder

createTable

protected void createTable(Table table,
 StringBuilder ddl,
 boolean temporary,
 boolean recreate)

Description copied from class: AbstractDdlBuilder

Outputs the DDL to create the table along with any non-external constraints as well as with external primary keys and indices (but not foreign keys).

Overrides:

createTable in class AbstractDdlBuilder

recreate - TODO

writeColumnAutoIncrementStmt

protected void writeColumnAutoIncrementStmt(Table table,
 Column column,
 StringBuilder ddl)

Description copied from class: AbstractDdlBuilder

Prints that the column is an auto increment column.

Overrides:

writeColumnAutoIncrementStmt in class AbstractDdlBuilder

writeGeneratedColumn

protected void writeGeneratedColumn(Table table,
 Column column,
 StringBuilder ddl)

Overrides:

writeGeneratedColumn in class AbstractDdlBuilder

getSelectLastIdentityValues

public String getSelectLastIdentityValues(Table table)

Description copied from class: AbstractDdlBuilder

Generates the SQL for querying the id that was created in the last insertion operation. This is obviously only useful for pk fields that are auto-incrementing. A database that does not support this, will return null.

Overrides:

getSelectLastIdentityValues in class AbstractDdlBuilder

Parameters:

table - The table

Returns:

The sql, or null if the database does not support this

writeCastExpression

protected void writeCastExpression(Column sourceColumn,
 Column targetColumn,
 StringBuilder ddl)

Description copied from class: AbstractDdlBuilder

Writes a cast expression that converts the value of the source column to the data type of the target column. Per default, simply the name of the source column is written thereby assuming that any casts happen implicitly.

Overrides:

writeCastExpression in class AbstractDdlBuilder

processTableStructureChanges

protected void processTableStructureChanges(Database currentModel,
 Database desiredModel,
 Table sourceTable,
 Table targetTable,
 List<TableChange> changes,
 StringBuilder ddl)

Description copied from class: AbstractDdlBuilder

Allows database-specific implementations to handle changes in a database specific manner. Any handled change should be applied to the given current model (which is a copy of the real original model) and be removed from the list of changes.
In the default implementation, all AddPrimaryKeyChange changes are applied via an ALTER TABLE ADD CONSTRAINT statement.

Overrides:

processTableStructureChanges in class AbstractDdlBuilder

Parameters:

currentModel - The current database schema

desiredModel - The desired database schema

sourceTable - The original table

targetTable - The desired table

changes - The change objects for the target table

 Column column,
 StringBuilder ddl)

Description copied from class: AbstractDdlBuilder

Prints the default value of the column.

Overrides:

printDefaultValue in class AbstractDdlBuilder

shouldUseQuotes

protected boolean shouldUseQuotes(String defaultValue,
 Column column)

Overrides:

shouldUseQuotes in class AbstractDdlBuilder

getSqlType

public String getSqlType(Column column)

Description copied from class: AbstractDdlBuilder

Specified by:

getSqlType in interface IDdlBuilder

Overrides:

getSqlType in class AbstractDdlBuilder

Parameters:

column - The column

Returns:

The full SQL type string including the size
