Oracle

Oracle tables and views can be documented in Predict with file objects of type OT and OV respectively. These file objects can be used to generate DDMs or CREATE TABLE/VIEW statements.

This document covers the following topics:

Naming Conventions
Oracle Table, File Type OT
Oracle View, File Type OV

Naming Conventions

The following naming conventions apply for Oracle objects (Files of type OT and OV)

Upper / lower case

IDs must be entered in upper case. If the Predict parameter General Defaults > Miscellaneous > Upper/lower case / Object ID is set to L and you try and enter a file ID containing lower case letters, an error message is given.

See also section Defaults in the Predict Administration documentation.

Length

Table/View names for Oracle objects can have up to 30 characters.
A fully qualified ID (Creator + Hyphen + Table/View name) must not exceed 32 characters.

Permitted characters

IDs containing special characters must be enclosed in double quotes, for example:
```
"USR1"-"FIL£ABC"
```
See overview of permitted characters in Naming Conventions.

Oracle Table, File Type OT

Attributes

Note:
Parameters not listed below are described in other sections of this documentation: Parameters common to all object types, for example Keys, are described under Global Attributes. Parameters common to all file types, for example Literal name, are described under Common File Attributes. See also Common Parameters for SQL File Types.

Parameters
Pctfree	If an integer from 1 - 99 is specified here, the clause `PCTFREE` `n` is generated in the `CREATE TABLE` statement. `PCTFREE` reserves a set amount of room in every block allocated to a table for future updates to that table's data.
Pctused	If an integer from 1 - 99 is specified here, the clause `PCTUSED` `n` is generated in the `CREATE TABLE` statement. `PCTUSED` specifies the minimum level of space usage that Oracle will maintain for each block of the table.
Initrans	If a value from 1 - 255 is entered here, the clause `INITRANS` `n` is generated in the `CREATE TABLE` statement. `INITRANS` is the initial number of transaction entries that are allocated within each block.
Maxtrans	If a value from 1 - 255 is entered here, the clause `MAXTRANS` `n` is generated in the `CREATE TABLE` statement. `MAXTRANS` specifies the maximum number of transactions that may update a data block concurrently.
Tablespace name	If a tablespace name is entered here, the clause `TABLESPACE` name is generated in the `CREATE TABLE` statement. This name represents the tablespace in which the table will be created.
Cluster name	If a cluster name is entered here, the clause `CLUSTER` name is generated in the `CREATE TABLE` statement. The table is to be included in the specified cluster.
Cluster column	Table columns that correspond to the cluster columns of the cluster specified under Cluster name.
Check constraint name	If a table check expression has been defined and the name of a check constraint is entered here, the following clause is generated in the `CREATE TABLE` statement: CONSTRAINT constraint_name CHECK (check_expression)
Storage clause
If specified, the values below are used in the `STORAGE` clause generated with the `CREATE TABLE` statement. All of the values below must be specified as integers.
Initial	The size in bytes of the first extent allocated when the object is created - the original amount of space allocated to the object.
Next	The size in bytes of every subsequent extent to be allocated.
Minextents	The total number of extents to be allocated when the segment is created.
Maxextents	The total number of extents, including the first, which can ever be allocated.
Pctincrease	The percent by which each NEXT extent will grow over the last extent allocated.

See your Oracle documentation for more information on these Oracle-specific parameters.
