# Sybase

Sybase tables and views can be documented in Predict with file objects of type YT and YV respectively. These file objects can be used to generate DDMs or `CREATE TABLE/VIEW` statements.

This document covers the following topics:

- Naming Conventions for Sybase

- Sybase Table, File Type YT

- Sybase View, File Type YV

## Naming Conventions for Sybase

The following naming conventions apply to files documenting Sybase tables and views.

### Upper / lower case

If the Predict parameter General Defaults > Miscellaneous > Upper/lower case / Object ID is set to L, the following attributes of Sybase objects are stored in upper and lower case as entered:

- File ID (object IDs containing lower case letters are not recommended)

- DV field expressions

- SQL verifications

- Check expressions

- Constraint names

See also section Defaults in the Predict Administration documentation.

### Length

- Table/View names for Sybase 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.

Parameters
