Interface SQLColumnI

All Known Implementing Classes:

PostgreSQLColumn, SQLColumn

public interface SQLColumnI

Interface representing a database column definition in the MyTISM schema generator.

Method Summary

Modifier and Type	Method and Description
boolean	equals(SQLColumnI o) Compares this column definition with another for schema equality.
CBOAttributeI	getAttribute()
java.lang.String	getColtype()
java.lang.String	getCreateStatement() Generates the SQL string required to create this column.
java.lang.String	getName()
java.lang.String	normalizeColumnType(java.lang.String typeName, int type, int size) Normalizes a database-specific column type string into a standard representation.

Method Detail

getName

java.lang.String getName()

Returns:

The logical name of the column.

getColtype

java.lang.String getColtype()

Returns:

The fully normalized SQL data type of the column (e.g. "varchar(255)").

getAttribute

CBOAttributeI getAttribute()

Returns:

The underlying schema attribute definition.

normalizeColumnType

java.lang.String normalizeColumnType(java.lang.String typeName,
                                     int type,
                                     int size)

Normalizes a database-specific column type string into a standard representation.

Parameters:

typeName - The raw type name from the database metadata.

type - The JDBC java.sql.Types integer code.

size - The column size/width.

Returns:

The normalized column type.

getCreateStatement

java.lang.String getCreateStatement()

Generates the SQL string required to create this column. Implementations MUST ensure that the column name is safely quoted.

Returns:

The column definition string (e.g. "\"col_name\" int8").

equals

boolean equals(SQLColumnI o)

Compares this column definition with another for schema equality.

Parameters:

o - The other column definition.

Returns:

true if both name and normalized column type are equal.
