This section describes the attribute types for a table. Not all JDBC attribute types are implemented by all databases. Using an unsupported type will result in errors during table creation. In addition, databases often implement types in slightly different ways, so the descriptions below may not be accurate in all cases. ![]() This type is used to represent 64-bit signed integers. ![]() This type is used to represent 32-bit signed integers. ![]() This type is used to represent 16-bit signed integers. ![]() This type is used to represent 8-bit integers that may be signed or unsigned. ![]() This type is used to represent an integer with a value of 1 (True) or 0 (False). ![]() This type is used to represent fixed precision and scale numeric data with at least the specified precision. ![]() This type is used to represent fixed precision and scale numeric data with exactly the specified precision. ![]() This type is used to represent 64-bit floating precision numbers. ![]() This type is used to represent 32-bit floating precision numbers. ![]() This type is used to represent dates. ![]() This type is used to represent times. ![]() This type is used to represent date and time data. ![]() This type is used to represent fixed-length character data. ![]() This type is used to represent variable-length character data. ![]() This type is used to represent large amounts of variable-length character data. ![]() This type is used to represent fixed-length international character data. ![]() This type is used to represent variable-length international character data. ![]() This type is used to represent large amounts of variable-length international character data. ![]() This type is used to represent fixed-length binary data. ![]() This type is used to represent variable-length binary data. ![]() This type is used to represent large amounts of variable-length binary data. |
Index |
The type of index or constraint to create for the column. Indexes and constraints are only created if the table is created. The valid values for the column type are listed below: PrimaryKey: Create a Primary Key index on the column. Unique: Only one of each non-null value is allowed in the column. NotNull: Nulls are not allowed in the column. UniqueNotNull: Only one of each value is allowed in the column. Nulls are not allowed. |
