Constructor Detail

SybaseBuilder

public SybaseBuilder(Platform platform)

Creates a new builder instance.

Parameters:

platform - The plaftform this builder belongs to

Method Detail

createTable

public void createTable(Database database,
               Table table,
               Map parameters)
                 throws IOException

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 SqlBuilder

Parameters:

database - The database model

table - The table

parameters - Additional platform-specific parameters for the table creation

Throws:

IOException

writeTableCreationStmtEnding

protected void writeTableCreationStmtEnding(Table table,
                                Map parameters)
                                     throws IOException

Writes the end of the table creation statement. Per default, only the end of the statement is written, but this can be changed in subclasses.

Overrides:

writeTableCreationStmtEnding in class SqlBuilder

Parameters:

table - The table

parameters - Additional platform-specific parameters for the table creation

Throws:

IOException

writeColumn

protected void writeColumn(Table table,
               Column column)
                    throws IOException

Outputs the DDL for the specified column.

Overrides:

writeColumn in class SqlBuilder

Parameters:

table - The table containing the column

column - The column

Throws:

IOException

getNativeDefaultValue

protected String getNativeDefaultValue(Column column)

Returns the native default value for the column.

Overrides:

getNativeDefaultValue in class SqlBuilder

Parameters:

column - The column

Returns:

The native default value

dropTable

public void dropTable(Table table)
               throws IOException

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

Overrides:

dropTable in class SqlBuilder

Parameters:

table - The table to drop

Throws:

IOException

dropForeignKey

public void dropForeignKey(Table table,
                  ForeignKey foreignKey)
                    throws IOException

Generates the statement to drop a foreignkey constraint from the database using an alter table statement.

Overrides:

dropForeignKey in class SqlBuilder

Parameters:

table - The table

foreignKey - The foreign key

Throws:

IOException

dropIndex

public void dropIndex(Table table,
             Index index)
               throws IOException

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

Overrides:

dropIndex in class SqlBuilder

Parameters:

table - The table the index is on

index - The index to drop

Throws:

IOException

dropForeignKeys

public void dropForeignKeys(Table table)
                     throws IOException

Creates external foreignkey drop statements.

Overrides:

dropForeignKeys in class SqlBuilder

Parameters:

table - The table

Throws:

IOException

getSelectLastIdentityValues

public String getSelectLastIdentityValues(Table table)

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 SqlBuilder

Parameters:

table - The table

Returns:

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

getEnableIdentityOverrideSql

protected String getEnableIdentityOverrideSql(Table table)

Returns the SQL to enable identity override mode.

Parameters:

table - The table to enable the mode for

Returns:

The SQL

getDisableIdentityOverrideSql

protected String getDisableIdentityOverrideSql(Table table)

Returns the SQL to disable identity override mode.

Parameters:

table - The table to disable the mode for

Returns:

The SQL

getQuotationOnStatement

protected String getQuotationOnStatement()

Returns the statement that turns on the ability to write delimited identifiers.

Returns:

The quotation-on statement

turnOnQuotation

public void turnOnQuotation()
                     throws IOException

Writes the statement that turns on the ability to write delimited identifiers.

Throws:

IOException

turnOnIdentityOverride

public void turnOnIdentityOverride(Table table)
                            throws IOException

Writes the statement that turns on identity override mode.

Parameters:

table - The table to enable the mode for

Throws:

IOException

turnOffIdentityOverride

public void turnOffIdentityOverride(Table table)
                             throws IOException

Writes the statement that turns off identity override mode.

Parameters:

table - The table to disable the mode for

Throws:

IOException

copyData

protected void copyData(Table sourceTable,
            Table targetTable)
                 throws IOException

Writes a statement that copies the data from the source to the target table. Note that this copies only those columns that are in both tables. Database-specific implementations might redefine this method though it usually suffices to redefine the SqlBuilder.writeCastExpression(Column, Column) method.

Overrides:

copyData in class SqlBuilder

Parameters:

sourceTable - The source table

targetTable - The target table

Throws:

IOException

writeCastExpression

protected void writeCastExpression(Column sourceColumn,
                       Column targetColumn)
                            throws IOException

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 SqlBuilder

Parameters:

sourceColumn - The source column

targetColumn - The target column

Throws:

IOException

addColumn

public void addColumn(Database model,
             Table table,
             Column newColumn)
               throws IOException

Overrides:

addColumn in class SqlBuilder

Parameters:

model - The database model

table - The table

newColumn - The new column

IOException

dropColumn

Writes the SQL to drop a column.

Parameters:

IOException

dropPrimaryKey

public void dropPrimaryKey(Table table)
                    throws IOException

Writes the SQL to drop the primary key of the given table.

Parameters:

table - The table

Throws:

IOException

changeColumnDefaultValue

public void changeColumnDefaultValue(Table table,
                            Column column,
                            String newDefaultValue)
