22 | /** |
|
23 | * <p> |
|
24 | * Supports the Derby / DB2 / SQL92 standard for defining Binary data fields |
|
25 | * with either CHAR(#) FOR BIT DATA or VARCHAR(#) FOR BIT DATA. This can be |
|
26 | * used in Platform implimentors initialize() methods, by using lines like: |
|
27 | * </p> |
|
28 | * <code> |
|
29 | * setSchemaDomainMapping(new SizedForBitDataDomain( |
|
30 | * SchemaType.BINARY, "CHAR", "1")); |
|
31 | * setSchemaDomainMapping(new SizedForBitDataDomain( |
|
32 | * SchemaType.VARBINARY, "VARCHAR")); |
|
33 | * </code> |
|
34 | * <p> |
|
35 | * This will cause the Column.getSqlString() method to produce items similar to: |
|
36 | * </p> |
|
37 | * <code> |
|
38 | * CHAR(#) FOR BIT DATA |
|
39 | * VARCHAR(#)FOR BIT DATA |
|
40 | * </code> |
|
41 | * <p> |
|
42 | * Where: # is the size= schema attribute or a default size specified in the |
|
43 | * constructor. |
|
44 | * </p> |
|
45 | * <p> |
|
46 | * Note that this is dependent on the platform implimentation correctly defining |
|
47 | * BINARY and VARBINARY as having a size attribute in the "hasSize()" method. |
|
48 | * </p> |
